Coping strategies

Each time we face our fear, we gain strength, courage, and confidence in the doing – Theodore Roosevelt


I’m not certain Theodore Roosevelt actually said that – but who cares?! It’s a great statement. For the person living with persistent pain, though, it can be the last thing you want to hear. After all, it’s tough enough getting up and just doing the normal things let alone challenge yourself! So… how can a health professional help?

Let’s briefly recap. Self efficacy is the confidence I can do something successfully if I wanted to. It’s a robust predictor of many health behaviours including exercise, stopping smoking, eating healthily and coping well with persistent pain (Jackson, Wang, Wang & Fan, 2014; Williams & Rhodes, 2016). It was first introduced as a concept by Bandura as part of his theoretical model of behaviour change, and further discussed in an experimental study in a paper investigating systematic desensitisation processes, arguing that this approach to treatment created and strengthened expectations of personal efficacy (Bandura & Adams, 1977). Bandura argued that people develop a sense (expectation) of self efficacy from their own performance, watching others succeed, being persuaded by someone that yes indeed you have the skills to achieve, and also awareness of physiological arousal from which people can judge their own level of anxiety.

Self efficacy is more than a simple “general confidence” construct, however. It’s far more selective than this. For example, although I believe I can successfully dance in my lounge with no-one there and the curtains closed, this does not translate to me dancing on a stage on my own in the spotlights with an audience watching! Self efficacy refers to confidence to succeed and produce the outcome I desire in a given context – and that’s extremely important for pain management, and in particular, exercise for people experiencing pain.

How does self efficacy improve outcomes? There are at least two ways: (1) through the actions taken to manage or control pain (for example, gradually increasing activity levels but not doing too much) and (2) managing the situations associated with pain (for example, people with low self efficacy may avoid activities that increase pain, or cope by using more medication (Jackson, Wang, Wang & Fan, 2014).

To examine how self efficacy affects outcomes, Jackson and colleagues (2014) conducted a meta-analysis of papers examining this variable along with other important outcomes. Overall effect sizes for relationships between self efficacy and all chronic pain outcomes were medium and highly significant. This is really important stuff – we don’t find all that many studies where a single variable has this much predictive power!

As a moderator, the adjusted overall effect size (r=.50) of self efficacy and impairment was larger than the average effect sizes of meta-analyses on relations between disability and fear-avoidance beliefs, and pain as a threat for future damage and challenge for future opportunities. Self efficacy has stronger links with impairment than cognitive factors such as fear-avoidance beliefs and primary appraisals of pain (Jackson, Wang, Wang & Fan, 2014).  Age and duration of pain were the strongest moderators of these associations and suggest that reduced self-efficacy can become entrenched over time. In other words – as time passes, people experience fewer opportunities for success and begin to expect they won’t ever manage their pain well.

An important point is made by these authors: how we measure self efficacy matters. They found that self efficacy measures tapping “confidence in the capacity to function despite pain” had
stronger associations with impairment than did those assessing confidence in controlling pain or managing other symptoms.

Bolstering self efficacy – not just about telling people they can do it!

Given that self efficacy is domain-specific, or a construct that refers to confidence to do actions that lead to success in specified situations, here are a few of my questions:

  • Why are most people attending pain management programmes provided with gym-based programmes that don’t look at lot like the kinds of things people have to do in daily life? It’s like there’s an expectation that “doing exercise” – any exercise – is enough to improve a person’s capabilities.

    BUT while this might increase my confidence to (a) do exercise and (b) do it in a gym – but does it mean I’ll be more confident to return to work? Or do my housework?

  • How often are people attending gyms told to “push on”, or to “stop if it hurts”? And what effect does this have on people?

If their confidence is low, being told “just do it” is NOT likely to work. People need to experience that it’s possible to do things despite pain – and I think, to be able to handle a flare-up successfully. Now this is not going to happen if we adopt the line that getting rid of all pain is the aim, and that flare-ups should be avoided. If we want people to deal successfully with the inevitable flare-ups that occur, especially with low back pain, then we need to (a) be gentle, and grade the activities in an appropriate way (b) have some “ways of coping” we can introduce to people rather than simply telling them they can cope or reducing the demands (c) have other people around them also coping well (and that includes us health professionals)

  • Ensure we attribute change to the person, not to us.

That’s right: not to our sparkling personality, not to our special exercises, not to the machines we use, not to the techniques we have – you get the drift? Progress must be attributed to the person and his or her skills and perseverance. Because, seriously, all this arguing over which exercise regime is best doesn’t stack up when it’s actually self efficacy that predicts a good outcome.

And for case managers who may read this: just because someone has successfully completed an exercise programme, or a vocational programme with exercise as a component, this does not mean the person can manage successfully at work. Well, they may manage – but they may utterly lack confidence that they can. Context matters.

The confidence that you’ll succeed if you try…


Self efficacy. It’s a word bandied about a lot in pain management, and for a group of clinicians in NZ, it’s been a shock to find out that – oh no! They’re not supporting self efficacy with their patients very much! It means “confidence that if I do this under these conditions, I’ll be successful”.

Self efficacy is part of Bandura’s social learning theory (click here for the Wikipedia entry) where he proposed that much of psychological treatment is driven by a common underlying mechanism: to create and strengthen expectations of personal effectiveness. Bandura recognised that we don’t always have to personally experiment through trial and error in order to learn. Self efficacy expectations were thought to develop from personal experience (let me do, and I’ll learn how); watching other people try (show me, and I’ll see if you succeed, then I’ll copy you); verbal persuasion that aims to convince that you have the capabilities to manage successfully (encourage me, let me know I can, and I’ll try); and how physiologically aroused or alert you are (if I feel confident inside, I’ll try but if I feel anxious or stressed I’m less inclined to) (Bandura, 1977).

Bandura and colleagues established that “different treatment approaches alter expectations of personal efficacy, and the more dependable the source of efficacy information, the greater are the changes in self-efficacy.” (Bandura & Adams, 1977, p. 288). The conclusions drawn from this mean that treatments where people DO and succeed are more effective at enhancing their belief in self efficacy, while watching others, or being told how to do something are far weaker at building this effect.

Bandura began working on this theory while pondering how psychological treatments, particularly for systematic desensitisation or graded exposure, generated their effects. Systematic desensitisation aimed to reduce arousal levels and thus avoidance while being in a relaxed state – therefore the person is exposed to increasingly “aversive” stimuli (stimuli you want to avoid) while remaining calm and relaxed. Bandura thought that there were other factors involved in avoidance behaviour, developing his theory that expectations of negative consequences alone can generate fear and defensive behaviour and that this isn’t necessarily reflected in autonomic arousal and actions. Bandura hypothesised that reducing physiological arousal improved performance not by eliminating a drive to escape – but instead by increasing the confidence that the person can successfully manage the situation.

For parents, the idea that if you believe you can do what you set out to do, is embodied in the little book “The Little Engine That Could” (Piper, 1930/1989). Remember? The little engine that couldn’t because all the bigger engines said so, but then tried and tried and believed he could – and he did!

So, what does this have to do with pain management?

Let’s paint a scenario. Allan comes to see a hands-on therapist because he has a sore back. He believes that hands-on therapy is the thing, because others have said it’s really good. He goes, gets his treatment and wow! Things improve! The next time he has a sore back (because, you know, it almost always comes back) what does he do? Well, on the basis of his past experience, he heads to his hands-on therapist, because he’s confident this will help his pain. The problem is, his therapist has moved town. He’s a bit stuck now because in his town there are not many therapists doing this particular kind of treatment – what does he do? He doesn’t believe that anyone else can help, and he has no belief that he can manage by himself. He has little self efficacy for managing his own back pain.

Self efficacy is not about whether a person can do certain movements, it’s about believing that the person can organise skills to achieve goals within a changing context – not just what I will do, under duress, but what I can do, what I’m capable of doing, and what I say I’ll probably do.

Self efficacy is not a belief that a specific behaviour will lead to a certain outcome in a certain situation, it’s the belief that I can perform that behaviour to produce the outcome.

So, self efficacy isn’t a generalised attitude – it’s a specific belief about certain actions, certain outcomes in certain situations. It’s not a personality trait like hardiness, or resilience, or general confidence or self-esteem, it’s about being confident that I can generate a solution to a problem in a particular part of my life.

The times when we’re least confident are often when we’re facing a new experience, or we’ve had a bad experience previously. Particularly if we’ve seen other people fail at the same thing, or succeed but do so with much fear and loathing. In the case of pain, there are ample opportunities to have a bad experience in the past, and to learn from other people around us that – oooh back pain is something to be afraid of, and you can’t manage it alone – you need to get help from someone else. Consequently, many people have very low self efficacy for successfully dealing with a bout of low back pain.

And health professionals: we can foster this.

How? By implying that success is due to what we do, rather than being a natural process of recovery. By suggesting it’s something about our “magic hands” or pills, or injections or surgery or special exercises, or “using the core correctly”. In doing so, we’re generating a belief that the person cannot manage alone. That it’s not what the person does, but the magic hands, pills, injections, surgery, special exercises or using the core…

Damush, Kroenke, Bair, Wu, Tu, Krebs and Poleshuck (2016) found that self management approaches to pain increase self efficacy, self management actions, and reduced pain intensity and depression in a group of community patients with chronic musculoskeletal pain and depression. A typically tough group to work with because confidence to succeed at anything is pretty low in depression. Self management aims to ensure the credit for recovery lies with the person doing things that help – creating and supporting a belief that the person has the capability to successfully manage their situation. The techniques? Simple strengthening and stretching exercises, progressive muscle relaxation, and visualisation, in a group setting. Strategies that typically don’t need technology, but do provide support. Information about the natural history of recovery was included – so people were given realistic and optimistic information about their recovery, whether it meant pain reduction, or not. The usual goal setting, problem-solving, and positive self talk were encouraged, and people set goals each week to achieve – maybe based on something from the session, or something the person wanted to do for themselves.

This is not a high-tech approach. This is simple, straightforward pain management as it has been done for years (right back as far as the mid-1970’s and Sternberg!). And through it, these people become increasingly confident that they could successfully manage their own mood and pain independently. As a business model it’s probably not the best for repeat business – but oh how good for those participants who could go away and live their lives without having to think of themselves as patients.

More on self efficacy in the next couple of weeks – we can help people to become confident that they can succeed at managing their pain if it should happen again.

Managing sleep problems – a medication-free approach (iv)


The fourth step in learning to sleep well within an ACT framework, is build. My previous posts were: Discover and Accept and Welcome.

In build, we’re beginning to build new practices. This is about learning how much sleep you need, and when you need to head to bed and wake up again.

I know when I had trouble sleeping at night (I refused to call it insomnia, but it most definitely was!), I thought I’d tried everything to help. I had used all the sleep hygiene strategies like no devices in bed, no TV in bed, do some relaxation as I lay down, have a regular bed-time and wake-up time – and one of the things I tried to do was eliminate coffee after lunchtime. While most of the time coffee isn’t a problem for me, I learned that when I was vulnerable to not sleeping, coffee and similar substances (including chocolate and alcohol) were not good for me. And today I still don’t drink coffee after lunch and limit myself to three or so cups a day.

So… what’s different about ACT and this stage of learning to sleep again?

Well, people with pain often talk about being interrupted by their pain – of waking up in the middle of the night because of pain and then not being able to get back to sleep. While there is some truth to the idea that we wake because of pain, in fact we all wake up over the course of a night. You’ll know the typical “sleep architecture” (click here for a nice explanation) where we fall into a deep stage of sleep fairly soon after heading to bed, and that we have periods of REM or rapid eye movement sleep (dreaming sleep) at regular intervals over the night. What you may not be as aware of is that in the periods just before and just after REM sleep, we’re actually awake. Not very awake – but awake enough to roll over and get comfy again. If your bladder does what mine does, I usually have a quick trip to the loo around 2.30ish, and go right back to sleep again.

When you have pain, chances are greater than you are more aware of those lighter periods of sleep and, like I do with my bladder, notice that you are awake. If you then start noticing your pain… or your worries… or your mind starts dropping comments to you, then it’s possible you’ll stay awake. Partly this is because the biological drive to fall into a deep sleep at the beginning of the night has been partly satisfied. Partly also because experiences like pain are very salient or important. So are noises (the cry of a baby, that tapping sound on the window, the car roaring down the road) and during the lighter periods of sleep we’re more likely to wake fully rather than just roll over. We’re not actually waking more often as much as waking more fully, and perhaps for longer than normal.

Building new patterns means some basic “rules” – but rules that are held lightly. In other words, it’s fine to change things up a little from time to time (after all, birthdays, travel, having a cold, or getting a puppy are all things that can disrupt sleep), but broadly these things seem to be habits of good sleepers:

  1. Heading to bed around the same time-ish each night (or within 20 – 30 minutes of this time). Same applies to waking up – and to help you wake, an alarm clock (I do use my phone for this), and in winter, I use a bright SAD light, and bump up the temperature on my electric blanket. Light and warmth both tend to make you wake up a bit more quickly, so it’s helpful for me during winter when I have seasonal affective disorder (winter depression).
  2. Knowing that it’s normal to take around 10 – 15 minutes to fall asleep, and being OK with this.
  3. Changing how long you sleep for will take a few weeks – it’s a habit! So don’t go changing your bedtime or wakeup time too often. If you’re using sleep restriction (going to bed a little later than normal, perhaps getting up a little earlier) you can return to a more “normal” length as part of fine-tuning how long you need to sleep for your needs. But, don’t change things too often!
  4. If you have a late night out (or if you’re travelling over a time zone or two), try to get up at your usual time. Yes, this means keeping the same wake time over the weekends as the week days!
  5. Develop a kind of “wind down” habit – but again, hold this lightly because sometimes there are enjoyable events on late, or you have people visiting, that may mean you’re a little more alert than normal. But on the whole, basically spend around 30 – 45 minutes giving your mind signals that you’re heading to bed. This means cleaning your teeth, checking the doors, stopping watching TV or going on devices, maybe get into your jimjams (PJs!) and heading to bed with a book or magazine.
  6. When you’re in bed, just quietly lying there, letting thoughts wander in and out without getting caught up in the content, and you’ll notice yourself quietly falling asleep. This is totally normal. If you do get caught up in your mind chatter, as soon as you notice you are gently bring your attention to your breathing and the sensations of lying in bed, and this should (at this point in your journey) help you fall asleep.

You can see it’s not too different from what I hope you’ve been practicing all along – just that instead of fighting with those thoughts, or getting all tangled up in them, you’ve got skills to let them go, and just be there in the darkness, resting.

There are a lot of specific issues you may also encounter – things like your partner who snores like a chainsaw, or twitches all night long (I’m the guilty party here!); or when you have a cold or a stuffy nose – the former might take a little longer to deal with, but the latter is usually just for a week or so and I tend to be happy using decongestants just for those few nights when I cannot breathe…. As for the partner noise or twitching, like dealing with your thoughts this is probably about you dealing with your thoughts about the noise or twitching! Again, try welcoming or being willing to listen to or feel those habits. Making some room for them rather than getting caught up in thoughts of smothering him or her! And go back to your usual mindfulness practice.

Finally – the last step is living! We tend to put life on hold when we try to control rotten sleep patterns.  Now it’s time to know that while sleeping badly can come again from time to time, you have skills to roll with it – you know you can manage if you avoid fighting with it or trying to control it. Take those steps to build your new sleep habit, and go out there and DO again!

 

Managing sleep problems – a medication-free approach (iii)


More on sleeping the ACT way. Step one was discover – all the things you’re doing to help yourself sleep, but in your attempts to control the uncontrollable (thoughts, feelings, memories, worries, sensations, the environment and so on). And hopefully you’ve seen that these things can be counter-productive. That flash new pillow and bed is pretty useless if you travel somewhere. The pills need to be stopped at some point – and then you have to withdraw from them. And the thoughts, and sensations (including pain) just carry right on there not matter what you do.

So step two is to accept: accept what you can control, and what you can’t. Radically, this means changing some of the things you do to get to sleep – like pills (but get medical help for this process), doing relaxation, wearing your eyeshades and earplugs, getting up and doing things when you can’t sleep. It usually means a bit of mind chatter!

The common mind chatter is “I’ll fail”; “I know I won’t sleep and then I’ll be useless the next day”; “if I can’t sleep with my pills and earplugs, how will I sleep without them?”; “I’ll feel lousy the next day”; “I’ve slept this badly my entire life, it’s too late for me”; “why me? It’s a punishment”; “but I’ve got [a new job, a baby, a puppy, going on holiday]”; “I’m too tired”

It’s likely, as you begin doing this, you’ll be in bed wide awake – and it’s at this point you can choose. In that moment, you can decide to listen to your mind – or think of your mind as holding an opinion, but one you do not have to follow. In ACT language, what you’re doing here is learning to accept, or be willing to sit with (lie with), to make room for not sleeping rather than struggling to control it. You can’t control your risk factors, you can’t control that you’ve learned to be awake at this time. You can’t control your thoughts about this – but you can lie there and just notice the things your mind is dumping on your doorstep. This isn’t “giving up” – this is radical willingness to come alongside and be with your own sleeplessness.

The best way to learn to do this is – you guessed it, mindfulness.

Now mindfulness is NOT about getting you to fall asleep. You may fall asleep or feel drowsy which is cool, but if you try to use mindfulness “to fall asleep” you’re again trying to control the problem and mindfulness can then become an empty process. You ARE allowed to let your mind wander… just gently bring it back to where you want it to be. Practicing mindfulness can be done anywhere and everywhere – for a few short seconds while cleaning your teeth, sitting in the car, walking through a door – or longer, like at the end of the day, or in the morning.

Some ways to be mindful: notice your senses by bringing your mind to sounds, sights, smells, tastes, touch. Just list all the things you experience – like “a bird chirp”, “the weight of my legs on the seat”, “the smell of coffee”…and as your mind wanders off, as it will, bring it back gently to what you want to focus on.

Another one to try: close your eyes for a few seconds and notice any thoughts or images that pop into your mind. List it – thought, image, work worry, dinner planning.

This skill is one of the most important and useful skills when you’re learning to sleep again. When you lie in bed wide awake, it’s easy to get caught up in the content of what your mind is bringing to  you, rather than just noticing that you are thinking. The problem is, thoughts your mind brings often lead to that heart thump and dry mouth that keeps you wide awake! Instead, directing your focus on to your breathing, or your body contact on the bed, are simple things that help you just notice and be in the present.

If you have pain, mindfulness is one way of letting you experience the ache without that “Oh no, it’s really bad tonight” judgements of that ache. Gently letting yourself notice where you’re sore – and equally, where you’re not sore – and guiding your mind around your body, noticing every part, the painful and the non-painful – allows you to be present with your pain, without fighting against it. Practicing this skill many times during the day really helps you develop this skill. And don’t be surprised if your mind starts trying to either judge or solve the problem of pain, because that is simply the mind doing what it’s done since forever. Be kind to your mind, and bring your attention back to your breath, or your left earlobe, or your belly button, or your little toe…

At night, in bed, mindfulness is not about helping you relax and fall asleep. What it’s there for is to help you guide your mind away from being caught up in the content of your thoughts or feelings or sensations, and back onto just noticing that you are thinking, and bringing your attention onto something like your breath. It can be scary doing this at night because we often want to get out of bed or control what we’re thinking and force ourselves into sleep. And you know it doesn’t work! What mindfulness does is let your brain and mind know that being awake isn’t a threat – remember the flight, fright, freeze response? By letting your mind know you’re not buying into the horror stories, and instead you’re being OK with simply lying there noticing, you’re teaching your mind to let go of the struggle.

  • Start with feeling the sensation of the bed against your body, from the toes to the head. When your mind begins “minding”, bring your attention to your breath. If you get the urge to move or get up (actually, your mind brings the urge), notice it and choose to stay in bed, and bring your attention back to your breath or touch.

Welcome: You’ll find your mind will have a good go at dumping scary thoughts on you when you decide to be present and stay. Remember it’s your mind’s opinions – and be gentle with your thoughts, feelings and yourself. Stay with it, notice your breathing, make room to feel a bit tired (because you were going to be tired anyway, right?!), and be kind, but firm, with your mind, and bring your attention to your breath yet again. You’re resting your body while you’re lying down, and that’s a good thing.

If you find you have a frequent flyer – a thought or worry or sensation that comes visiting when you’re trying to sleep  – you can simply name it “Hi worry”, or “thinking”, or “here you are scared”, or “back again, pain”. Welcoming the thoughts or feelings may feel odd –  but once you’ve noticed it, labelled it, and then welcomed it, go back to your breathing or noticing your body. You can become quite creative with this process – if you have a vivid imagination for visual images, try projecting your thoughts onto a movie screen, or turning them into cartoon letters, or characters from a movie (my pain is a grumpy witch!), or a ball of string all tangled up, or a scrunched towel.  Some people have taken to imagining their thoughts as different voices – squeaky “I’m scared” or deep “I’ll never sleep tonight” – these strategies are ways to help you step back from the content of what your mind is telling you, and see your thoughts as simply thoughts made by your mind.

Managing sleep problems – a medication-free approach (ii)


Last week I described the “conventional” CBT for insomnia approach (CBTi), but this week I want to introduce an Acceptance and Commitment Therapy (ACT) approach which is superficially similar to CBTi but holds to some of the fundamental principles of ACT: mindfulness, and letting go of control. As is typical for ACT, there are no hard and fast absolutes and instead there is a focus on workability – what works, in context.

Most of the content of today’s post is drawn from my personal experience and The Sleep Book by Dr Guy Meadows. There are five basic steps and according to the book it should take five weeks to get sleep sorted. I’m not as convinced about timeframes, so I’ll describe it as five steps.

  1. Discover: this step is about discovering what triggers and maintains insomnia, and focuses on why struggling to start sleeping is counter-productive. That’s right – stop struggling!
  2. Accept: well, with a name like ACT you’d expect some acceptance, right? This is not about resigning yourself to nights of poor sleep, but rather a willingness to let go of the struggle, to be fully present in the now – rather than reminiscing about the past, or predicting the future.
  3. Welcome: everything that shows up in your mind and body (after all, they’re there whether you want them or not!).
  4. Build: a new sleeping pattern by identifying how much sleep you need and when you need it.
  5. Live: during the day and sleep during the night!

Like absolutely any behaviour change, this process is not always easy! It takes persistence, courage and doing things that may not feel like sensible things to do! Let’s begin.

Discover: we do a whole heap of things to try to get to sleep – normal sleepers don’t. Normal sleepers just put their heads on the pillow, maybe let their minds wander over the day, and then gently fall asleep. When people with insomnia try to sleep, we try all manner of things to get to that state – and many of those things either prolong the sleeplessness, or actually wind it up!

Meadows describes four factors associated with the start of insomnia:

  • risks which may be getting older, being female, being a worrier or depressed, having a family history of rotten sleep, maybe being generally full-on;
  • triggers may include life stress, some medical conditions like irritable bowel or a fracture and yes, pain, and medications or alcohol, time zone changes and so on;
  • arrivals are memories, thoughts, sensations, emotions and urges that come to visit when we’re trying to get off to sleep but can’t – and these are partly the fight, flight or freeze response which happens when we begin worrying, or are part of the triggers (and we often think it’s those things that need to be got rid of); and finally
  • amplifiers, or things that are meant to be helping reduce insomnia but can actually make it worse: things like spending longer in bed, sleeping in, going to be earlier, having naps – and oddly enough, some of the things we’re traditionally advised to do to help us sleep. Things like reading in low light, having a warm bath or warm milk drink, watching TV, listening to the radio, playing with devices like the phone…. Even some of the things we do because we’re not sleeping – like getting out of bed and doing things like checking emails, doing some exercise, going to the loo – all of these things are done to try avoid the chitter-chatter of our mind, or eat least to control or distract from it, yet can paradoxically train your brain to be awake right when you really want to sleep… even things like keeping the room dark, wearing earplugs, doing relaxation, sleeping in a different bed from your partner, trying a new mattress or pillow can be a step too far and train your brain to think controlling these thoughts about sleep is the Thing To Do.

I’ll bet that, like me, most people have done all these things – and some of them are part of CBTi. There is a place for them in moderation – but it’s even better to develop the skill of not being caught up in trying to control our thoughts, worries, feelings, body sensations when we’re heading to sleep.

Now I’m sure this is where people are going “yeah but…” and giving a whole list of why your situation is different. Would you be willing to keep reading and look at some alternatives?

The risk of trying to control these arrivals and amplifiers is that while they don’t work, it’s too scary NOT to do them. Your brain learns, as a result, that sleep is a problem. And what does the brain like best? Oh that’s right – solving problems. Except that if you’ve ever tried to “make yourself” stop thinking, or feeling – have you noticed that you just can’t? Try it now: try and make yourself feel happy. Yeah… you either have to recall something enjoyable from the past, or anticipate something in the future. And while you’re doing that, your brain is cranking up. It’s worse if you try to stop yourself from thinking or worrying because that old fight, flight or freeze response kicks in and up goes your heart rate and perspiration and breathing…

So the first step of this programme is to discover all the things you’re doing to control the uncontrollable. We can’t stop feelings, thoughts, memories and so on from arriving. They just do. So fighting with them and trying hard to get rid of them just does not work – they’re there AND you’re feeling stressed because you can’t get rid of them!

Managing sleep problems – a medication-free approach (i)


I’ve recently completed two posts on assessing sleep problems in people experiencing persistent pain, and today I turn my attention to strategies for managing sleep problems – without medication. Why without medication? Because to date there are no medications for insomnia that don’t require a ‘weaning off’ period, during which time people often find their original sleep problems emerge once again… I’m not completely against medications for sleep or pain – but I think they need to be used with care and full disclosure about the effects, side-effects, and the need to eventually withdraw from them.

The approach I’m advocating is a modified form of cognitive behavioural therapy for insomnia (CBTi). CBTi is a form of treatment that is now considered to be first line therapy by both the British Association for Psychopharmacology (Wilson, Nutt, Alford, Argyropoulos, Baldwin, Bateson et al, 2010), and the American College of Physicians (Qaseem, Kansagara, Forciea, Cooke, Denberg et al, 2016). It includes sleep hygiene, cognitive therapy for the thoughts and beliefs associated with sleep, and sleep restriction for those who clinically need it. The modified version I advocate is based on Dr Guy Meadows ACT-based approach and I’ll cover that next week, but I’ll describe the classical CBT approach first.

Basic principles

The basic idea behind a CBT approach to insomnia is that although the initiating event may be out of our control, it’s unlikely to be maintaining the problem – and the factors maintaining the problem are typically the habits people have, and the thoughts and beliefs about their sleep problem.

Sleep is a behaviour that is infinitely malleable, as anyone who has travelled far enough on long-haul flights will know (and parents of small babies as well!). There are cues we use to decide when we should head to bed, and how long we should stay asleep. Bodies in turn respond to these cues and modify automatic processes such as digestion, urine production, and body temperature to ensure we stay asleep for as long as needed. When those cues change – for example, we’re in a new time zone when it’s light at the “wrong” time, and we’re hungry at the “wrong” time, we have trouble staying asleep until the body adjusts. Some people say we can manage a two-hour time zone shift every 24 hours, but in some sensitive people even a one-hour daylight savings change can upset the apple-cart!

If sleep is a habitual behaviour, then we can manipulate the cues to our benefit when sleep is elusive. We learn to associate things like the routine we follow prior to going to bed, light in the room, the “winding down” process we use, and even the timing of our snacks and drinks as a way to signal to the body/mind that we’re sleepy/tired.

There are three basic steps in CBTi: stimulus control (aka sleep hygiene), cognitive therapy, and sleep restriction – with the usual relapse prevention steps an essential part as well.

Sleep hygiene (stimulus control)

The basis of sleep hygiene is to control the stimuli associated with going to sleep so that we clearly indicate to the body/mind that it’s time to get to sleep. That means some basic “rules” around what we do in the time preceding getting into bed, and what we do when in bed trying to sleep.

The golden rule is that the bed is for sleep and sex – not for worrying in, not for watching TV or using the computer or phone or tablet, not for arguing in, not for talking on the phone. If you’re awake in bed for longer than 20 minutes, it’s time to get out of bed until you’re sleepy/tired (more on this in a moment), keeping the lights down low, doing something tedious or boring, then returning to bed to actually sleep.

Simple, commonsense things like keeping the room dark and warm, blocking out the worst of the noise, NOT using a TV or radio or any other noise-making device to go to sleep, ensuring caffeine intake is limited, having a regular bedtime and wake-up time, not taking naps through the day and timing when exercise and relaxation are undertaken are all part of sleep hygiene and most of us are aware of these steps. If they’re not familiar to you, this site is a good one – click.

Cognitive therapy

The cognitive therapy part is about managing the thoughts and attitudes that can exacerbate the sleep problem – things like having a busy mind, worrying about not being able to sleep, believing that it’s crucial to have a certain number of hours of sleep or the next day will be awful, getting that sinking dread as bedtime approaches, following any number of almost (and sometimes actual) obsessive rituals to achieve sleep – and so on…

As usual, with any conventional CBT, dealing with these thoughts involves firstly reality testing – Is it true that you must have a certain number of hours of sleep or the next day will inevitably be terrible? Must the room be absolutely silent or sleep will elude you? Then challenging or disputing those thoughts – “It’s possible I’ll feel tired tomorrow, but I can still function even if I’m not at my best”, “It might take me longer to fall asleep but I’ll get to sleep even though I can hear a clock ticking”.

These simple approaches are reasonably easy to implement – and they are effective. But if sleep is still a problem, and the person isn’t getting more than 4 hours sleep a night, it’s time to bring in the big guns.

Sleep restriction

There are two parts of altering sleep habits that are particularly challenging: getting out of bed after 20 minutes of being awake (especially in the wee hours of the morning!); and using sleep restriction. Neither are easy, yet both are effective.

The idea behind sleep restriction is to reduce the amount of time being in bed while not actually being asleep. Simple huh? So that period from when you first hop into bed and until you actually fall asleep is called sleep latency – and the longer your sleep latency, the less sleep you actually get. You become inefficient at sleeping, and worst, your body/mind learns that it’s OK to be in bed wide awake, and as I mentioned earlier, people begin to associate even going into the bedroom as a negative thing which revs up the autonomic nervous system making it even more difficult to fall asleep.

The nuts and bolts are to work out what time you actually fall asleep, and only go to bed at that time. So if you stay awake until 2.00 or 3.00am, you only go to bed at 2.00am. And you keep your morning wake-up time the same as normal. Yes, this means you end up being only able to sleep for the time between 2.00am and 7.00am! Ouch!

The idea is to extinguish the “habit” of being awake while in bed, reducing the association between being in bed and wide awake, while getting you absolutely tired and sleepy that you fall asleep into a deep sleep quickly. Once this falling asleep part happens regularly (usually for a week or so) then it’s possible to begin a very gradual process of bringing the bedtime back to a more reasonable hour – I usually suggest 15 minute increments, returning to the previous step if falling asleep begins to be difficult.

The process is reasonably difficult – not because it’s hard to stay awake (after all, the person has been practicing it for some time!) but because of the mind chatter. It’s truly tough when your mind starts having a go at you, suggesting you can’t sleep, or you’ll be so incredibly tired you won’t cope, or you’ll be cranky and that it’s dangerous and how on earth  will you go at work without any sleep? And this is where having access to a really good clinician can be helpful, although there are apps that provide a pretty good alternative if a human isn’t available.

For a detailed examination of the literature on sleep restriction therapy, Kyle, Aquino, Miller, Henry, Crawford, Espie & Spielman (2015) provide a really good systematic analysis of how sleep restriction is employed in research trials.  For a plain language version of CBTi, this is a good description – click

As I mentioned above, I’ll be going through a slightly different version of CBTi – an Acceptance and Commitment Therapy approach to insomnia that is also gaining popularity and an evidence base. Come right on back next week for that exciting episode!

Assessing problems with sleep & persistent pain


Problems with sleep affect most of us from time to time. We know we might find it difficult to get off to sleep because of a busy mind, a different bedroom, changes to our schedule – but for most of us, sleep returns to our normal fairly quickly. For some of us, though, sleep problems continue for weeks, months or even years. And for people living with persistent pain, sleep can be one of the most difficult things to deal with, yet it’s also one of the most common (McCracken & Iverson, 2002). Studies of sleep problems in people with fibromyalgia show abnormal sleep continuity as well as changes in sleep architecture – this looks like increased number of times waking, a reduced amount of slow wave sleep and an abnormal alpha wave intrusion in non rapid eye movement, termed alpha-delta sleep (Dauvilliers & Touchon, 2001). People with fibromyalgia may also experience primary sleep disorder such as sleep apnoea or periodic leg movements during sleep.

The effect of rotten sleep is quite clear: pain increases the day following a disrupted night’s sleep, while high levels of pain on one day has less of an impact on subsequent sleep – but if you’ve been sleeping poorly for a while, all of this becomes something of a blur (Johnson, Weber, McCrae & Craggs, 2017; Slavish, Graham-Engeland, Martire & Smyth, 2017)! When we add in the effects of poor sleep on daily activity, and begin to unpack the relationships between sleep, pain and mood (Goerlitz, Sturgeron, Mackey & Darnell, 2017) well it’s a bit of a complicated matter, and one that I think we need to address when someone comes in for help with their pain.

Assessing unrefreshing sleep or poor sleep can be a reasonably straightforward process, but it needs to be carried out systematically. The event/s that initiate poor sleep may be very different from the events that maintain poor sleep, and while it’s interesting to know what started the sleep difficulties – in the end it’s possibly more important to work out what’s maintaining it.

The following is my attempt to outline what I look for when I’m discussing sleep with someone.

1. Is sleep really a problem? Sounds a bit odd, but some people have a strong belief that they need a certain number of hours of sleep a night, and when they’re not getting that magical number, it can be quite worrying – and actually kick off a sleep problem!

  • My key question here is do you wake feeling like you’ve had a good sleep? The number of hours of sleep is irrelevant, to a large extent, if you wake up feeling refreshed. If the person I’m talking to wakes up feeling OK I quickly swing into trying to understand why they’re worried about their sleep – and reassuring them that having a certain sleep duration is not fixed. In fact, sleep length changes over time – remember when you were a kid and slept for hours and hours? And when you were a teen and sleep in until midday if you could, but stayed up most of the night? These are pretty normal changes in pattern and nothing to worry about.

If you don’t feel refreshed, then I dig a little deeper…

2. What’s your sleep routine? This is about finding out the time someone goes to bed, how long it takes to fall asleep, what time a person wakes up, and gets up. I’ll also ask about the pre-bedtime routine: what’s the evening routine like? when do the screens go off? what’s the last drink of the evening? what’s the bedroom environment like?

  • I’m looking for a consistent bedtime at around the same time each night, a “wind down” ritual where the same things happen each night to prime the mind for sleep. I’m also looking for factors that might make it more difficult to fall asleep once in bed – screen time (devices, laptops, TV), dealing with worries, solving problems, having arguments, difficulty getting comfortable.
  • I’m also looking for a consistent wake up time, and whether the person gets out of bed then – or lies in bed and maybe falls asleep again…
  • A comfortable room temperature, a dark room, relatively little noise: all of these very basic things help keep bed for sleep (and sex) but not for much else.

The reason these basic “sleep hygiene” factors help is that our sleep pattern is malleable. It changes depending on environmental factors like light, noise and temperature. This is why we end up having jetlag – it takes a little while to adjust to the new daily light patterns (especially when you travel from Christchurch, NZ to somewhere like Norway!). Our body temperature drops during the night, our digestive processes slow down (that’s why we tend not to do “number twos” at night) and why we pee a lot less at night than during the day. Setting up a consistent routine helps us retain these habits and “teach” the mind/body to sleep at the correct time.

3. What substances do you use? I’m interested in the usual suspects: caffeine (not only coffee, but tea, energy drinks, dark chocolate), but also alcohol, the timing of medications, and that late night snack.

  • When sleep onset is a bit fragile it’s probably best not to have coffee and allied substances after mid-afternoon, and for some people (like me!) it’s best not to have them after lunch.
  • Medications for persistent pain are often sedating, so people need to know how to use this side effect for the best – and that often means taking medications earlier than first thought.
  • It also means for us, recognising that some medications alter sleep architecture (particularly meds given for, paradoxically, insomnia!). Alcohol might help people get to sleep but it changes the sleep architecture, preventing you from falling into that deepest sleep phase – and waking you up to pee halfway through the night, if you don’t do that already!
  • I also check whether people are smokers, and if they are, whether they wake in the morning absolutely gasping for a smoke, or whether they smoke during the night. Nicotine withdrawal can keep someone awake during those brief periods before and after dreaming sleep, so may need to be managed with patches.
  • Food is also something I check – snacks at midnight are the stuff of school stories, but can become a learned behaviour that we associate with being awake at that time, and maintain disrupted sleep. Maybe a mid-evening protein-based snack is a better option.

4. What’s going through your mind (or what’s your mind telling you) about your sleep? Having hopefully dealt with the basics of sleep hygiene (though I haven’t included exercise yet – that’s coming!), I’m keen to understand the person’s mind chatter about their sleep.

  • Worries, rumination and attempts at problem-solving (yes I’ve solved the problem of world peace!) can all keep us from falling asleep. What we do about those thoughts depends on the sleep management approach we’re using.
  • Often, the worries are actually worries about not sleeping – that paradoxically keep us from falling asleep! Feeling bothered about “how am I going to cope tomorrow if I don’t sleep”, or “I’m going to be so tired tomorrow, I know I won’t manage” are really common.
  • Along with worries about not sleeping, every other unsolved problem seems to pop up courtesy of your mind – this can happen because the person is too busy during the day to stop and ponder (and it’s quiet at night… fewer distractions!) so it’s worth finding out what is going through the person’s mind and dealing with those issues.

5. What’s your pattern of sleeping through the night? This is about the pattern of arousals – when, how long for, what the person does during these times.

  • Some understanding of normal sleep architecture is useful here so you can help the person understand why waking just before/just after dreams occurs.
  • Reviewing the habits at these times helps to understand the factors that maintains being awake at the wrong times! Waking briefly but without being aware of it is normal, but when internal or external factors intrude during lighter periods of sleep, we become more aware of being awake and can begin to do things that keep us awake, like watching TV, turning the radio on, having a snack, worrying.

To be continued…

These are some of the very fundamentals of assessing sleep problems. Next week I’ll review some more – and the week after look at strategies that can help!

Pain – or disability?


One of the fundamental distinctions we need to make when working with people who experience pain is to understand the difference between experiencing pain – and the behaviour or actions or responses we make to this experience. This is crucial because we can never know “what it is like” to experience pain – and all we have to rely on as external observers is what we see the person doing. Differentiating between the various dimensions associated with our experience of pain makes it far easier to address each part in the distinct ways needed.

Let me explain. We know the current definition of pain – an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in such terms (IASP, 1979). One of the key points of this definition was to remove the need for nociception as a requirement for pain to be present. So when we unpack what we understand about pain, the first step is to recognise that it’s an experience. Something we can never share with another person – just like we can’t share joy, the taste of a great craft beer, or what a lover’s touch is like.

We therefore have an inexact relationship between two concepts: nociception, or the biological mechanisms at play until the point at which we are conscious of pain; and pain, or the experience of what it is like to have an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in such terms.

But wait, there’s more. Given that this experience is a subjective, internal and personal experience – how do we know when someone is experiencing pain?

When I ask students, their answer is “oh you can see grimacing, wincing, or they tell you” – and it’s true! But let’s notice something: they’re all behaviours. Things people do, either involuntarily or voluntarily, to signal that they’re sore. Behaviours or actions are not a direct indication of “what it is like” to experience pain. Like nociception and pain, there is an inexact relationship between what someone does when they’re experiencing pain – and their resultant behaviour. So we now have three somewhat overlapping concepts: nociception (biology), pain (experience), and behaviours (actions). They overlap because there is no direct 1:1 relationship between these concepts – although in some cases it may seem like there is.

What else influences our pain experience? If you’ve been paying attention to my blog these last few weeks, you’ll know that thoughts or beliefs and emotions also influence both our experience of pain and our behaviour. For example, if we know that the pain we’re experiencing is for good (such as post-surgical pain after hip replacement), we tend to be more forgiving, or at least more willing to experience it than if someone attacked us with a scalpel down some back alley! We have plenty of evidence that simply knowing the supposed cause, and something about the biology of pain, can help people to feel a little differently about it (emotions), and to move differently (behaviour) (Moseley & Butler, 2015; Tegner, Frederiksen, Esbensen & Juhl, in press), while emotions in both experimental and clinical studies have been shown to strongly affect pain intensity – and subsequent behavioural responses (Orenius, Raij, Nuortimo, Naatanen, Lipsanen, & Karlsson, 2017). Once again, the relationships are not exact – which is almost always the case when we’re studying complex systems!

Because thoughts, beliefs and emotions have both impacts on nociceptive processes and on pain experience and behaviours, I’ve depicted them as overlapping (if there was a way to show this in 3-D believe me, I would!).

But wait, there’s more!

We know context makes an enormous difference to a person’s experience of pain AND the behaviours they take in response to their pain. While contextual factors don’t directly influence nociception, these factors do influence thoughts and beliefs, emotions, and behaviour. For example, we know that in adolescents with pain, parental responses influence the amount of treatment seeking (Stone, Bruehl, Smith, Garber & Walker, 2018); and that spouses or partners of people living with pain can affect both pain intensity and behaviour because of the way they interact (Burns, Post, Smith, Porter, Buvanendran, Fras & Keefe, 2018). We also know that in different communities, responses to pain can differ: people who pursue body suspension (being pierced and suspended by hooks) are supported by those around them to “hang in there” (no pun intended!). Factors such as legislation make a difference to pursuing treatment, while treatment itself can perpetuate disability and may even increase attention to pain.

Why bother explaining all this?

The implications of understanding these associations are quite profound. Firstly, nociception is a small but important contributor to our pain experience. Most pain starts with a nociceptive stimulus, even if it ultimately ends up less influential than cortical ‘interpretive’ processes. Secondly, the experience we have of pain is something we can’t share – and thirdly the only way we can begin to infer that another person has pain is via their behaviours, or what they do. This means pain measures like the visual analogue scale, FACES scale, numeric rating scale are not direct measures but are used by people to give a message about their pain. All behaviour is influenced by both our thoughts/beliefs and emotions and contextual factors including who is nearby, past responses they’ve made to our messages, what’s normal or expected in various contexts, and the purpose we believe our behaviour will serve. And of course, many of the influences and behaviours we do are not things we’re consciously aware of because we’ve been doing them since we were born.

So when I think about what we might do to help someone with their pain, I firstly acknowledge that I can’t directly influence someone’s own experience. I’m working to influence what they do about their pain, their relationship to their pain, their beliefs and understanding, their emotions and how they communicate this to other people around them. And to me, the first step is being ready to hear what people believe about their pain. Only after I’ve successfully conveyed this to the person can I ever begin to come alongside them to help them change what they do.

Clinical reasoning – and cognitions


Possibly one of the most hotly discussed aspects of clinical reasoning and pain relates to thoughts and beliefs held by both people experiencing pain and the clinicians who work with them. It’s difficult to avoid reading papers about “pain education”, “catastrophising”, “maladaptive thinking”, but quite another to find a deeper analysis of when and why it might be useful to help people think differently about their pain, or to deal with their thoughts about their experience in a different way.

Cognition is defined by the APA Dictionary of Psychology as

1. all forms of knowing and awareness, such as perceiving, conceiving, remembering, reasoning, judging, imagining, and problem solving. Along with affect and conation, it is one of the three traditionally identified components of mind.

2. an individual percept, idea, memory, or the like. —cognitional adj. —cognitive adj.

Cognitions are arguable The Thing most accessible to ourselves and most distinctive about humans – indeed, we call ourselves “homo sapiens” or “wise man” possibly because we can recognise we have thoughts! Although, as you can see from the definition above, many aspects of cognition are not as readily available to consciousness as we might imagine.

From the early days of pain management, explanations about the biology of pain have been included. Indeed, since 1965 when Melzack and Wall introduced the Gate Control Theory, in which modulation and descending control were identified, clinicians working in pain management centres have actively included these aspects of pain biology as part of an attempt to help people with pain understand the distinction between hurting – and being harmed (see Bonica, 1993).

The purpose behind the original approaches to “explaining pain” were to provide a coherent explanation to people in pain as to the “benign” nature of their experience: in other words, by changing the understanding people held about their pain, people were more likely to willingly engage in rehabilitation – and this rehabilitation largely involved gradually increasing “up time” and reducing unhelpful positions or activity levels. Sound familiar? (see Moseley & Butler, 2015).

Of course, in the early days of pain management, specific relationships between thoughts and both automatic and volitional behaviour were unclear. What we know now is that if I wire someone up to a biofeedback machine, measuring say heart rate variability, respiration and skin conductance, and then I mention something related to the person’s appraisals of their pain – maybe “Oh this really hurts”, or “I don’t think I’ll sleep tonight with this pain” those parameters I’m measuring will fluctuate wildly. Typically, people will experience an increase of physiological arousal in response to thinking those kinds of thoughts. In turn, that elevated arousal can lead to an increased perception of pain – and increased attention to pain with difficulty taking attention off pain (see Lanzetta, Cartwright-Smith & Eleck, 1976; Crombez, Viane, Eccleston, Devuler & Goubert, 2013).

So, the relationship between what we think and both attention to pain and physiological response to those thoughts is reasonably well-established, such that if someone reports high levels of catastrophising, we can expect to find high levels of disability, and reports of higher levels of pain. So far, so good. BUT how do we integrate these findings into our clinical reasoning, especially if we’re not primarily psychologically-oriented in our treatments?

The answer has been to dish out “pain education” to everyone – giving an explanation of some of the biological underpinnings of our experience. But for some of our patients this isn’t useful, especially if they have already heard the “pain talk” – but it has only hit the head and not the heart.

As Wilbert Fordyce was known to say “Information is to behaviour change as spaghetti is to a brick”. In other words – it might hit the brick and cover it, but it doesn’t change the brick, and neither does it move the brick!

You see, cognitions are not just “thoughts”, nor thoughts we are consciously aware of. Cognitions include implicit understanding, attention, the “feeling of what it is like to” and so on. And as occupational therapists and educators have found over the years, experiential learning (learning by doing) is one of the most powerful forms of behaviour change available (Kolb, 2014). People learn by experiencing something different. This is why cognitive behavioural approaches such as Acceptance and Commitment Therapy (ACT) so strongly endorse experiential elements.

Rather than attempting to change someone’s head knowledge of pain=harm, it might be more useful to help them experience doing something different and help them explore and generate their own conclusions from the experience.

I think both occupational therapists and clinicians who provide opportunities for movements and experiences (such as massage therapists, physiotherapists, osteopaths, chiropractors, myotherapists etc) are in an ideal position to guide people through new experiences – and then help them explore those new experiences. Rather than telling people what to think or believe (especially amongst those folks who are unconvinced by “book learning”!) we’re in a good position to help them work out what’s going through their minds – and what it feels like to do something differently. Instead of convincing, we can help people ponder for themselves. This is the essence of graded exposure: going from “OMG I can’t do that!” to “Oh yeah, I can master this”. It’s the difference between reading about how to ride a bicycle – and actually getting on a bike to learn to ride.

I agree that cognitive processes are really important in understanding a person’s experience of pain. I think, though, we’ve focused on overt thoughts to the detriment of trying to understand other aspects of cognition. We need to spend some more time exploring attention and distraction from pain; memories and how these influence pain; and to examine some of the implicit features of our understanding – and instead of approaching changes to thinking/understanding via the hammer of information dumping, maybe we can ponder the opportunities that arise from helping people experience something different and new.

When philosophy and evidence collide: is an occupation-focused approach suitable in pain management?


I have often described myself as a renegade occupational therapist: I like statistics, I think experimental research is a good way to test hypotheses, I don’t make moccasins (though I occasionally wear them!), I’m happy reading research and figuring out how I can apply findings into my clinical practice.

Occupational therapy is a profession that continues to evolve. The origins of occupational therapy lie back in the “moral” model of treatment for mental illness when advocates found that giving people things to do helped them become well (mind you, some of the reasons for admission to a “mental asylum” were things like “wandering womb”, novel reading, laziness and “female disease” read it here on Snopes). As time passed, occupational therapy was a way to “occupy” troops recovering from war wounds, and later, tuberculosis. At various points, occupational therapists have tried to enclose practice within prevailing models: anatomical, biomechanical, neurological. And then the scope broadens and the profession returns to “occupation” and all it means. Out of this latest movement, and informing occupational therapy practice today is the idea of “occupational science” – this is the “basic science” examining the factors that underpin occupational therapy practice (Yerxa, 1990).

Unlike most “basic sciences”, occupational science draws on areas of knowledge including anthropology, sociology and political science; all social sciences that bring their own philosophical biases to understanding social phenomena. Occupational science is about “what people do in daily life” – those routines, rituals, practices, customs and daily doings that support us in our roles, shape our place in the social world, and help us form an understanding of who we are in the world. Things like how we go about getting up, the way we serve a meal, the way we dress ourselves, how we go from one place to another, the hobbies and fun things we do – all fundamental building blocks of daily life. Occupational therapy, therefore, informed by occupational science, is focused on helping people participate in daily life as fully and equitably as possible, irrespective of health status, gender, ethnicity, religious belief, age and so on.

With a focus on not only helping people participate in occupations, but also using occupation as therapy, it’s not surprising to find a plurality of approaches to treatment. I have seen art used to help people with persistent pain represent the impact of pain on their sense of self – and to celebrate changes that have happened as a result of pain management. I have seen gardening used to help people become stronger, more confident to move and to reconnect with a hobby they had given up because of pain. I have seen people begin new hobbies (geocaching anyone?) as part of occupational therapy. I have used excursions to the local shopping mall to help people regain confidence and reduce their fear of crowded places where they might get bumped. Graded exposure is also an approach occupational therapists use to help people generalise their emerging skills to approach feared movements instead of avoiding them.

What I hope I don’t see is a return to a compensatory model for persistent pain. You know what I mean here: using gadgets or aids to “make life easier” when a person is dealing with persistent pain. Things like a special long-handled tool so people can pick something up from the floor – fine in a short-term situation like immediately post hip arthroplasty, but not so much when the problem is longstanding fear and avoidance. A special vacuum-cleaner so the person doesn’t have to bend – it’s so much easier yes, but it doesn’t address the underlying problem which can be remedied.

Why is a compensatory model not so good for persistent pain management? Well, because in most instances, though not all, the reason a person isn’t doing a movement when they’re sore is not because they cannot – but because that movement increases or might increase pain, and no-one really wants to increase pain, yeah? By providing a gadget of some sort, or even working through a way to avoid that movement, occupational therapists who use this sort of approach are ignoring the strong evidence that this reinforces avoidance as a strategy for managing pain, doesn’t address the underlying fear, and risks prolonging and actually reinforcing ongoing disability. This approach is harmful.

Helping people do things that might hurt isn’t a very popular idea for some clinicians and a lot of people living with persistent pain. It feels at first glance, like a really nasty thing to do to someone. BUT graded exposure is an effective, occupationally-focused treatment for fear of movement and fear of pain (Lopez-de-Uralde-Villaneuva, Munos-Garcia, Gil-Martinez, Pardo-Montero, Munoz-Plata et al, 2016). Used within an acceptance and commitment therapy model, graded exposure becomes “committed action” that’s aligned to values – and engaging in valued occupations is exactly what occupational therapy is all about.

Of course, not everyone enjoys this kind of work. That’s OK – because there are others who DO enjoy doing it! And it’s all in the way that it’s done – a framework of values, commitment, mindfulness and, that’s right, “chat therapy” – which some occupational therapists believe is right outside their scope of practice.

Now unless someone works in a vacuum, via some sort of mind-to-mind process, I cannot think of any therapist who doesn’t communicate with the person they’re working with. Humans communicate effortlessly and continuously. And “chat therapy” is about communicating – communicating skillfully, carefully selecting what to respond to and how, and focusing on clinical reasoning. Of course, if that’s ALL the treatment is about, then it’s not occupational therapy, but when it’s used in the aid of helping someone participate more fully in valued occupations using CBT, ACT, DBT or indeed motivational interviewing is one of the approaches occupational therapists can employ both within an occupation as therapy and occupation as outcome model.

I firmly believe that occupational therapists should follow an evidence base for their work. While I openly acknowledge the paucity of occupational therapy-specific research in persistent pain, particularly using occupation as therapy, there is plenty of research (carried out by other professions) to support approaches occupational therapists can adopt. After all, we already use developmental models, neurological models, sociological models, anthropological ones and yes, psychological ones. And that’s without venturing into the biomechanical ones! So it’s not an unfamiliar clinical reasoning strategy.

What makes occupational therapy practice in pain management absolutely unique are two things: a complete focus on reducing disability through enabling occupation, and a commitment to bringing skills developed “in clinic” outside into the daily lives and world of the people we are privileged to work with. What we should not do is focus on short-term outcomes like reducing (avoiding) bending with some new technique, while being ignorant of other occupational approaches. We are a fortunate profession because all of what we do is biopsychosocial, let’s not forget it.
