Coping strategies

Being mindful about mindfulness


I’m generally a supporter of mindfulness practice. It’s been a great discipline for me as I deal with everyday life and everything. I don’t admit to being incredibly disciplined about “making time for meditation” every day – that is, I don’t sit down and do the whole thing at a set time each day – but I do dip in and out of mindfulness throughout my day. While I’m brushing my teeth, slurping on a coffee, driving, sitting in the sun, looking at the leaves on the trees, cuddling my Sheba-dog I’ll bring myself to the present moment and take a couple of minutes to be fully present. Oddly enough I don’t do this nearly as often when I’m cold (like this morning when it’s about 8 degrees in my office!), or when I’m eating parsnip (ewwwww!), or waiting to see a dentist. Or perhaps that’s not odd at all, because I wonder if we have a skewed view on mindfulness and what it’s about.

My reason for writing this post comes from reading Anhever, Haller, Barth, Lauche, Dobos & Cramer (2017) recent review of mindfulness-based stress reduction for treating low back pain. In it, they found “MBSR was associated with short-term improvements in pain intensity (4 RCTs; mean difference [MD], −0.96 point on a numerical rating scale [95% CI, −1.64 to −0.34 point]; standardized mean difference [SMD], −0.48 point [CI, −0.82 to −0.14 point]) and physical functioning (2 RCTs; MD, 2.50 [CI, 0.90 to 4.10 point]; SMD, 0.25 [CI, 0.09 to 0.41 point]) that were not sustained in the long term.” There were only seven RCTs included in the study, with a total of only 864 participants, and many of the studies had no active control groups, so my interpretation is that there are flaws in many of the studies examining MBSR, and that it’s difficult to draw any conclusions, let alone strong conclusions.

Where do we go wrong with mindfulness? The first point about the studies included in Anhever and colleagues paper is that there is a difference between mindfulness in general and mindfulness based stress reduction – and although the difference may be minimal, it’s nevertheless worth understanding. MBSR is a full programme that includes mindfulness as one element (Kabat-Zinn, 1982). Mindfulness is a key component, yes, but the programmes include other elements.  The second point is that perhaps we’re assuming mindfulness to be something that it isn’t –  I suspect, from reading numerous articles in both the popular media and research papers, that mindfulness is being applied as another form of relaxation.

Relaxation training was introduced as part of a behavioural approach to managing stress. In pain management it’s been part of programmes since the 1970’s, particularly using forms of progressive muscle relaxation (See Dawn & Seers, 1998). The intention is to provide an experience that is incompatible with tension, and to develop the capability to down-regulate the body and mind to mitigate the stress response that is so often part of persistent pain.

Relaxation training can take many forms, and breath control is a common component. I use it often for myself, and when working with clients – I’m aiming to show people that although they may not be able to control heart rate or blood pressure, they can control breath and muscle tension. It’s useful especially as part of sleep management.

The thing with relaxation training is it’s entire purpose is to help downregulate an upregulated nervous system. Mindfulness, on the other hand, is not.

What is mindfulness about if it’s not about relaxation? Well, mindfulness has been defined in many different ways, but the one I especially like is by Kabat-Zinn (1990) “a process of bringing a certain quality of attention to moment-by-moment experience”.  This definition can be further unpacked by examining its components: “Mindfulness begins by bringing awareness to current experience—observing and attending to the changing field of thoughts, feelings, and sensations from moment to moment—by regulating the focus of attention.” (italics are mine) –  this quote is from Bishop, Lau, Shapiro and colleagues (2004) and is from a paper looking at defining mindfulness in an operational way (so we can be aware of what it means in practice, or as we teach others). These authors go on to say that this process leads to a feeling of being very alert to what is occurring in the here and now. I like to remind people that it’s about being here rather than remembering or anticipating what might.

So at least one part of mindfulness is learning how to attend to what YOU want to attend to, rather than being dragged back to memories, or forward to predictions, or to experiences or moments that you don’t want to notice at that moment.  The definition also points to noticing and experiencing what is happening, rather than thoughts or ruminations about what you’re experiencing. For people living with persistent pain, I think this is an invaluable tool for dealing with the interruptive effects of pain on attention.

A second aspect of mindfulness is an attitude – one of curiosity. When being mindful, you’re not trying to produce any particular state, instead you’re being curious about what you are experiencing, whether it’s something you’d ordinarily want to experience – or not. This approach to experience is really similar to what we’re aiming for in persistent pain management – acknowledging and being willing to experience what is, rather than attempting to avoid that experience, or quickly change it to something more palatable.

Now this aspect of mindfulness is often brought to bear on new and pleasant experiences – sometimes people are asked to mindfully eat a raisin, or mindfully examine a ballpoint pen (one of my favourites). But it’s also just as valid to bring this attitude to bear on less than pleasant experiences like my cold fingers and legs (it’s cold in my office this morning). Or to pain and where it is – and where it isn’t.

So I wonder if part of our approach to using mindfulness in pain management is incorrect. If we’re intending people to come away from mindfulness feeling relaxed and calm, perhaps we’re doing it wrong. If we think people should feel better after mindfulness, again, perhaps we’re doing it wrong. Sometimes, yes, these are the effects we’ll have. Other times, not so much. What we will always develop, over time, however, is better ability to focus attention where we want it to go, and more openness to being present to what is rather than struggling against it. And I think those are incredibly valuable tools in life, not just persistent pain management. And perhaps, just perhaps, if we began viewing our use of mindfulness in these ways, the outcomes from RCTs of mindfulness might show more of what it can do.

Mulling over the pain management vs pain reduction divide


I’ve worked in persistent pain management for most of my career. This means I am biased towards pain management. At times this creates tension when I begin talking to clinicians who work in acute or subacute musculoskeletal pain, because they wonder whether what I talk about is relevant to them. After all, why would someone need to know about ongoing management when hopefully their pain will completely go?

I have sympathy for this position – for many people, a bout of tendonosis, or a strained muscle or even radicular pain can ebb away, leaving the person feeling as good as new. While it might take a few months for these pain problems to settle, in many instances there’s not too much need for long-term changes in how the person lives their life.

On the other hand, there are many, many people who either don’t have simple musculoskeletal problems (ie they’re complicated by other health conditions, or they have concurrent issues that make dealing with pain a bit of a challenge), or they have conditions that simply do not resolve. Good examples of these include osteoarthritis (hip, knee, shoulder, thumbs, fingers) and grumbly old lower back pain, or peripheral neuropathy (diabetic or otherwise). In these cases the potential for pain to carry on is very present, and I sometimes wonder how well we are set up to help them.

Let’s take the case of osteoarthritis. Because our overall population is aging, and because of, perhaps, obesity and inactivity, osteoarthritis of the knee is becoming a problem. People can develop OA knee early in their life after sustaining trauma to the knee (those rugby tackles, falling off motorcycles, falling off horses, running injuries), or later in life as they age – so OA knee is a problem of middle to later age. People living with knee OA describe being concerned about pain, especially pain that goes on after they’ve stopped activities; they’re worried about walking, bending and maintaining independence – and are kinda pessimistic about the future thinking that  “in 10 years their health would be worse and their arthritis would be a major problem” (Burks, 2002).

To someone living with osteoarthritis, especially knee osteoarthritis, it can seem that there is only one solution: get a knee replacement. People are told that knee replacements are a good thing, but also warned that knee replacements shouldn’t be done “too soon”, leaving them feeling a bit stranded (Demierre, Castelao & Piot-Ziegler, 2011). Conversations about osteoarthritis are not prioritised in healthcare consultations – in part because people with knee osteoarthritis believe that knee pain is “just part of normal aging”, that there’s little to be done about it, and medications are thought to be unpleasant and not especially helpful (Jinks, Ong & Richardson, 2007).

I wonder how many healthcare professionals feel the same as the participants in the studies I’ve cited above. Do we think that knee OA is just something to “live with” because the problem is just part of old age, there’s an eventual solution, and meanwhile there’s not a lot we can do about it?

When I think about our approach to managing the pain of osteoarthritis, I also wonder about our approach to other pains that don’t settle the way we think they should. Is part of our reluctance to talk about pain that persists because we don’t feel we know enough to help? Or that we feel we’ve failed? Or that it’s just part of life and people should just get on with it? Is it about our feelings of powerlessness?

In the flush of enthusiasm for explaining the mechanisms of pain neurobiology, have we become somewhat insensitive to what it feels like to be on the receiving end when the “education” doesn’t reduce pain? And what do we do when our efforts to reduce pain fail to produce the kind of results we hope for? And the critical point, when do we begin talking about adapting to living well alongside pain?

What does a conversation about learning to adapt to pain look like – or do we just quietly let the person stop coming to see us once we establish their pain isn’t subsiding? I rather fancy it might be the latter.

Here’s a couple of thoughts about how we might broach the subject of learning to live with persistent pain rather than focusing exclusively on reducing pain:

  • “What would you be doing if pain was less of a problem?” My old standby because in talking about this I can begin to see underlying values and valued activities that I can help the person look at starting, albeit maybe doing them differently.
  • “What do you think are the chances of this pain completely going away?” Some might say this is about expectancy and I’m setting up a “nocebic” effect, but I argue that understanding the person’s own perspective is helpful. And sometimes, when a person has persistent pain and a diagnosis like osteoarthritis, their appraisal is less about catastrophising and more about holding a realistic view about their own body. It’s not about the appraisal – it’s about what we do about this. And we can use this perspective to built confidence and increase the importance of learning coping strategies.
  • “If I could show you some ways to deal with pain fluctuations, would you be interested in learning more?” All episodes of pain that persists will have times when pain is more intense than others – flare-ups are a normal part of recovering from, and living with persistent pain. Everyone needs to know some ways of going with, being flexible about or coping with flare-ups. I teach people not to focus exclusively on reducing pain during these flare-up periods. This is because even during rehabilitation we don’t want to use pain as a guide (it can be a cruel task-master). We know that rehabilitation can increase (temporarily) pain while the body habituates to new movement patterns, the brain gets used to new input, and the homunculus gets redefined. It’s great to be able to teach strategies that increase the sense of safety, security and down-regulation that can be lost in the initial onslaught of pain.

To summarise, not all pain problems settle. We can help everyone to be more resilient if we begin talking about ways of coping with flare-ups even during subacute pain, particularly if we avoid an excessive focus on trying to avoid them. Instead, we can begin to help people feel confident that flare-ups always settle down, and that they can manage them effectively by using effective self management.

…and now what we’ve all been waiting for: What do to about central sensitisation in the clinic


For the last couple of weeks I’ve posted about central sensitisation; what it is, and how to assess for it. Today I’m going to turn to the “so what” question, and talk about what this might mean when we’re in the clinic.  Remember that most of this material comes from Jo Nijs’ recent talks at the New Zealand Pain Society.
Firstly, remember that pain is an experience that people have, underpinned by neurobiology, but also, depending on the level of analysis, on interactions with others, on systems and how they work, on culture, on individual experiences, and of course, on interacting within a body within an environment or context. Everything I say from here on is based on these assumptions.

The first point Jo Nijs makes is that when we know a bit more about the neurobiology of persistent pain associated with central sensitisation, we can use this knowledge wisely when we help someone make sense of their pain. This doesn’t mean wholesale and broadcast “I-will-tell-you-all-I-know-about-pain-neurobiology-because-I-know-you-need-to-know-it-because-I-know-it-and-think-it’s-important” which is, truth to tell, a lot more about the know-it-all than the person in front of them! We need to earn the right to give information – that means establishing that we’ve heard the other person’s story and the current meanings they’ve made from their experience. It also means asking permission to share new information. It means thinking about WHY we want to share new information.

So what if the person doesn’t use the same groovy language we use to describe his or her understanding?! So what if they’ve got some of the newer ideas slightly skewed. In the end, what’s important is that the person understands these things:

  • Pain isn’t a direct reflection of what’s happening in the tissues.
  • Pain can be influenced by many things, some of which are physical forces (heat, pressure and so forth), some of which are ideas, and some are emotions. And there are a bunch of other variables that can influence the experience, including what else is going on around the person.
  • The brain is intimately involved with our experience of pain, and it’s a two-way street from body to brain and brain to body.
  • Persistent pain is more about neurobiology than tissue damage per se (but not exclusively about neurobiology).

Our job is to make sure the person understands these things, rather than our job being about “educating” people. The end result matters, rather than any particular process.

If we look at the evidence for helping people reconceptualise their pain, there’s plenty to show that this approach is useful – it’s been a key tenet of a self-management cognitive behavioural approach to pain management since at least the late 1970’s. The later research (from Butler, Moseley and Louw et al) is simply looking at this approach within a slightly different cohort and in a different context. Rather than being integrated with an interdisciplinary pain management programme, research from these guys shows that physiotherapists (in particular) can deliver this kind of information very effectively – and that it helps reduce the fear and subsequent efforts to avoid pain (such as not moving, seeking healthcare, and being worried about pain). Yay!

It’s true that there are many different ways to influence the descending modulatory system, and release endorphins. One of them is to help people understand their pain and be more confident about moving. Another is to place hands on the person – hence massage therapy, manual therapies, manipulations and so on. Nijs believes hands on therapy has best effect after you’ve gone through some of the reconceptualisation that’s often needed (Bishop, Torres-Cueco, Gay, Lluch-Girbes, Beneciuk, & Bialosky, 2015).

Similar arguments can be made for considering sleep management and stress management as an integral part of pain management. (To be perfectly honest, I always thought this was part of what we did…). So here’s the argument: we know most people with persistent pain experience rotten sleep. We also know that people are stressed by their experience of pain. Because poor sleep is associated with increased activation of glia in the prefrontal cortex, amygdala and hippocampus, and therefore are pro-inflammatory, pain is often increased after a poor night’s sleep. Sleep medications interfere with the sleep architecture, so it’s useful to consider nonpharmacological approaches to sleep management.

Three strategies to consider:

  • CBT for insomnia – here’s one resource to use
  • ACT or acceptance and commitment therapy – I’ve written a great deal about ACT, just use the search function on this blog for more
  • Exercise – OMG yes, exercise is effective! (just not right before bedtime, kthx)

Stress management is tougher. We can’t avoid experiencing stress – and neither can we live in a bubble where we don’t ever get exposed to stress. Instead, we probably all could do with learning multiple ways of managing stress. Things like realistic evaluations of the situation, increasing our capabilities for regulating our response to stress via biofeedback if need be, and using mindfulness as a strategy for being with stress instead of fighting against it, or folding beneath it.

I haven’t cited many references in this post – not because there aren’t many, but because there are SO many! And I’ll post more next week when I start looking at the rather sexy neurobiological examinations of processes used in pain management for years (yes, we’ve been doing it for a long time, we now have great explanations for how these things might work – though effect sizes are still small.)

A surfeit of learning


It’s been a busy few weeks as I’ve been at the San Diego Pain Summit and then the New Zealand Pain Society meeting where wonderful speakers presented on topics like exercise for pain, cognitive functional therapy, central sensitisation, opioid use in New Zealand, sensory profiles and other such topics. The chance to meet and spend time with clinicians who are passionate to not only learn about pain, but apply what they’ve learned in clinical practice is something I can’t miss.

What’s difficult, though, is deciding what to apply on Monday morning after having been to meetings or events where there’s so much new material to absorb. And that’s one of the problems, I think, in our clinical practice today. The years when it was relatively easy to do the same old, same old, have (thankfully!) gone – but in its place is the challenge of sifting through that new information and deciding what and how to do it.

So today I thought I’d go through some of the practices I’ve used – maybe it will help someone else?

Firstly, I try to take just one thing away from a meeting. If I absorb more than this, it’s fine, but one new thing is usually quite enough for me! Someone made the point that changing habits is hard – and, just for a moment, think about what we expect the people we treat to do, and then think about that last conference and what you intended to do, but just didn’t… Without  intention, planning and support to change what you do, you’ll carry on doing what’s easy, what’s worked before, and what feels “comfortable”. So be kind to yourself and pick just one thing. For me, that one thing is to feel OK about teaching people to ask “and what does that mean to you?” when someone is telling me their story about their pain.

Next, I let the rest of the information I heard just sit and percolate a while. This means I might casually read something related, or I might review the speaker’s slides or recordings, but I don’t do this in a way that I’m madly trying to cram in action points. This is because I’ve chosen one thing to do, and that’s enough. The rest of the information won’t just disappear because I’m letting it rest, it’s just going to connect with other concepts and pop out later when I stumble on it while reading something else.

To apply what I’ve learned, I plan. Yep, you heard it, I plan! Just like our clients, we need to make specific action plans if we’re going to do things differently. I think there are two factors to apply: the first is how important I think the concept/action is to me, the second is how confident I am to make a change.

  1. Importance: While simply selecting the single thing I take away from a meeting implies that I think it’s important, it’s worth considering why I decided it’s so important. So I list a few reasons I valued that concept. For me, it was the idea that we can uncover more of the real concerns of a person if we ask what it means to them, we can be more able to hear what the person really wants. I also took the idea that anyone: PT, OT, MT, Osteo, Chiro, Doc, Nurse ANYONE can ask this question. This is important to me because if that question isn’t asked, the person may go on fearing the worst even if they appear to be “doing well”. And we cannot rely on “someone else” asking this question. Even if we’re not psychologists, and so think that beliefs and attitudes are out of scope, we ARE experts in how the human body works. We know structure and function. This means we have a responsibility to help people understand what’s going on their body rather than living in ignorance or confusion.
  2. Confidence: It’s not enough to think that something is important. We need to make it easy to make a change. This means identifying what might get in the way of change and planning around that. It also means identifying what might make it easy to change and structuring life so it’s not hard. It could mean writing some “cheat sheets” giving brief phrases to use (Alison Sim and I used this approach in our recent workshop), or it might mean a poster in a prominent place to act as a reminder. It might mean removing something from the environment so you don’t use it as easily. It could mean simplifying for a couple of times. For me it will mean working through possible arguments people make against asking those questions about meaning, using open-ended questions. Often the questions relate to time available in clinic, scope of practice questions, “opening Pandora’s box” questions, “what do I say next” questions, or the “it’s not my focus” questions. I’ll work on responses to these in advance so I can explore what these mean to the clinician before asking if it’s OK to explain my perspective.

I ask myself “what would it look like if I applied this new strategy?”, or “how would I know I was using this strategy?”. I also take time to review how I’ve gone using that new strategy – recording myself, asking someone to sit in on a session, even just reviewing against the “cheat sheet” to see what I used, and what I could have used.

If you take a moment to review my process, hopefully you’ll see the elements of a motivational approach to behaviour change. I’ve written quite a bit about motivation – hope this helps you too!

 

What to do with the results from the PCS


The Pain Catastrophising Scale is one of the more popular measures used in pain assessment. It’s popular because catastrophising (thinking the worst) has been identified as an especially important risk factor for slow recovery from pain (Abbott, Tyni-Lenne & Hedlund, 2010), for reporting high levels of pain intensity (Langley, 2011), and for ongoing disability (Elfving, Andersoon & Grooten, 2007). I could have cited hundreds more references to support these claims, BTW.

The problem is, once the PCS is administered and scored: what then? What difference does it make in how we go about helping a person think a little more positively about their pain, do more and feel more confident?

If you haven’t seen my earlier posts about the PCS, take a look at this, this, and this for more details.

Anyway, so someone has high scores on rumination, helplessness and magnifying – what does this mean? Let’s say we have two people attending the clinic, one has really high scores on all three subscales, while the other has low or average scores. Both have grumbly old low back pain, both have had exercises in the past, both are finding it tough to do normal daily activities right now.

For a good, general pain management approach to low back pain, and once red flags are excluded (yes, the “bio” comes first!) this is what I do. I establish what the person thinks is going on and ask if it’s OK to talk about pain neurobiology. Together we’ll generate a pain formulation, which is really a spaghetti diagram showing the experience as described by the person (I used guided discovery to develop it). I then ask the person what they’d be doing if their pain wasn’t such a problem for them, perhaps what they’re finding the most frustrating thing about their situation at the moment. Often it will be sleep, or driving or cooking dinner, or perhaps even getting clothes on (shoes and socks!). I’ll then begin with helping the person develop good relaxed breathing (for using with painful movements), and start by encouraging movement into the painful zone while remaining relaxed, and tie this in with one of the common activities (occupations) the person needs or wants to do. For example, I’ll encourage bending forward to put shoes and socks on while breathing in a relaxed and calm way. I’ll be watching and also encourage relaxing the shoulders and any other tense parts of the body. For someone who is just generally sore but doesn’t report high pain catastrophising, I will also encourage some daily movements doing something they enjoy – it might be walking, yoga, dancing, gardening, whatever they enjoy and will do regularly every day for whatever they can manage. Sometimes people need to start small so 5 minutes might be enough. I suggest being consistent, doing some relaxation afterwards, and building up only once the person has maintained four or five days of consistent activity. And doing the activity the person has been finding difficult.

If the person I’m seeing has high scores on the PCS I’ll begin in a similar way, but I’ll teach a couple of additional things, and I’ll expect to set a much lower target – and probably provide far more support. Catastrophising is often associated with having trouble disengaging from thinking about pain (ruminating), so I’ll teach the person some ways to deal with persistent thoughts that hang around.

A couple to try: mindfulness, although this practice requires practice! It’s not intended to help the person become relaxed! It’s intended to help them discipline their mind to attend to one thing without judgement and to notice and be gentle with the mind when it gets off track, which it will. I ask people to practice this at least four times a day, or whenever they’re waiting for something – like the jug to boil, or while cleaning teeth, or perhaps waiting for a traffic light.

Another is to use a “15 minutes of worry” practice. I ask the person to set a time in the evening to sit down and worry, usually from 7.00 – 7.15pm. Throughout the day I ask the person to notice when they’re ruminating on their situation. I ask them to remind themselves that they’re going to worry about that tonight and deliberately put that worry aside until their appointment with worry. Then, at 7.00pm they are asked to get a piece of paper and write ALL their worries down for a solid 15 minutes. No stopping until 15 minutes is over! It’s really hard. Then when they go to sleep, I ask them to remind themselves that they’ve now worried all their worries, and they can gently set those thoughts aside because they won’t forget their worry, it’s written down (I think worry is one way a mind tries hard to stop you from forgetting to DO something about the worry!). People can throw the paper away in the morning because then it begins all over again.

Usually people who score high on the PCS also find it hard to be realistic about their pain, they’ll use words that are really emotive and often fail to notice parts of the body that aren’t in pain. By noticing the worst, they find it tough to notice the best.  I like to guide people to notice the unloved parts of their body, the bits that don’t hurt – like the earlobes, or the belly button. I’ll offer guidance as to what to notice while we’re doing things, in particular, I like to guide people to notice those parts of the body that are moving smoothly, comfortably and that look relaxed. This is intended to support selective attention to good things – rather than only noticing pain.

Finally, I give more support to those who tend to be more worried about their pain than others. So I might set the goals a little lower – walking for five times a week, two days off for good behaviour rather than every day. Walking for five minutes rather than ten. And I’ll check in with them more often – by text, email or setting appointments closer together. It’s important for people who fear the worst to experience some success, so setting small goals that are achieved can build self efficacy – especially when I try hard to offer encouragement in terms of what the person has done despite the odds. So, if the person says they’ve had a real flare-up, I’ll try to boost confidence by acknowledging that they’ve come in to see me even though it’s a bad pain day, that they’ve tried to do something instead of nothing, that talking to me about the challenge shows guts and determination.

People who see the glass as half empty rather than half full are just people. Like you and I, they’re people who have a cognitive bias. With support, we can help people view their pain differently – and that process applies to all of us, not just those with high scores on the PCS.

What is pain for?


We’re told we need pain – without the experience, we risk harming our bodies and living short lives. With pain, and for most people, we learn to not go there, don’t do that, don’t do that AGAIN, and look at that person – don’t do what they’re doing! Thirst, hunger, fear, delicious tastes and smells, the feelings of belonging, of safety and security, of calm and comfort: all of these are experiences we learn about as we develop greater control over our bodies.

Pain is an experience we learn to associate with actual or possible threat to “self”. Let’s take a moment to think about what “self-hood” means.

If I ask you “who are you?” you’ll tell me your name, probably your occupation, maybe where you live and who you live with. Baumeister (1997) suggests our sense of self is about “the direct feeling each person has of privileged access to his or her own thoughts and feelings and sensations.” He goes on to say “it begins with the awareness of one’s own body and is augmented by the sense of being able to make choices and initiate action.” We learn about who we are through interacting with the environment, but also as we interact with other people and begin to sort through our roles, contributions and relationships.

Of course, our sense of self changes over time and is reciprocally influenced by choices we make as well as opportunities (and threats) around us, both environmental and social.

We work really hard to avoid threats to our sense of self. For example, I’ll bet we’ve all seen that person who steadfastly refuses to stop colouring his hair, wearing the same clothing styles as he did in his 20’s, holding on to the same habits as he did at the same age even when he’s now in his 50’s, has a paunch, and still looks for partners 20 years younger than he is…  He still believes he’s that young stud despite the evidence in the mirror. And of course the same applies to women perhaps more so!

So what happens when our mind/body is threatened? How do we know it? And what do we do about it?

In this instance I’m not talking about social threats, though there’s interesting research suggesting that being socially excluded has similar neurobiological effects as being physically threatened (or experiencing pain – though this may reflect the distress we experience when we’re hurt and when we’re socially excluded – see Iannetti, Salomons, Moayedi, Mouraux & Davis, 2013; Eisenberger, 2015). I’m instead talking about threats to our physical body. Those threats may be violence from another person, physical trauma to the body, or the threat of physical harm to the body. When we experience these kinds of threats, and once an aspect of mind/body has disentangled the threat evaluation from whatever other goals we’re currently engaged in, we experience pain. Tabor, Keogh and Eccelston (Pain, in press) define pain in terms of action: an experience which, as part of a protective strategy, attempts to defend one’s self in the presence of inferred threat.

So pain is there to help us maintain an intact sense of self in the presence of threat – threat that we’ve inferred from our context (or drawn a conclusion from incomplete data). It’s part of a system that works to maintain “us” in the face of multiple threats that we encounter.

Tabor, Keogh and Eccleston also argue that pain is an experience designed to intrude on awareness to show that “boundaries have been reached and action must be taken”. Pain is one way our mind/body can give us an indication of boundary – just how much, or how little, we can do. For example, I experience pain when I bend my thumb down to reach my wrist – it’s one way I can learn how far I can bend without disrupting something! The purpose of that pain is to help “me” defend against doing really dumb things, like stretching my thumb out of joint!

Interestingly, when we feel overwhelmed by our pain, when we can’t defend against it (because it feels too intense, has meanings that threaten our deepest sense of self) we tend to withdraw from responding to everything else – our conversations stop, we don’t notice other people or events, we pull into ourselves and ultimately, we can lose consciousness (think of the accounts of early surgery without anaesthesia – the surgeons were kinda grateful when the patient lapsed into unconsciousness because at last they weren’t writhing to get away – see Joanna Bourke’s book “The Story of Pain” for some harrowing stories!).

When we lose consciousness, our sense of self disappears. We lose contact with the “what it is to be me”.

Our sense of self also disappears when we experience pain we can’t escape and we can’t make sense of. Throughout the time while people are trying to label their pain, establish the meaning of their symptoms, and while people are searching for a solution to their pain, people’s experience of both time and “who I am” is threatened (Hellstrom, 2001).

To me, this is one of the primary problems associated with pain – and one we’ve almost completely ignored in our healthcare treatments. All our treatments are aimed at helping “get rid of the pain” – but what isn’t so often incorporated in these efforts is a way of engaging and rebuilding a resilient sense of self. So while the pain may ebb away, the “self” remains feeling vulnerable and threatened, especially if there’s any hint of pain returning.

What can we do better? Perhaps talk about what vision a person has of themselves as a “self”. Help them work towards becoming the “self” they believe they are – or at least helping them express the underlying values that their “self” has previously been expressing. That way perhaps people can find flexible ways to express that “self” – which will make them more capable of living well under any circumstances.

What difference does it make to know about psychosocial risk factors?


The “psychosocial yellow flags” or risk factors for developing ongoing disability after a bout of acute low back pain have been promulgated in New Zealand since 1997. Introduced as part of the Acute Low Back Pain Guidelines, the yellow flags were lauded both locally and internationally and subsequently there have been many international guidelines which have adopted this kind of integration. But what exactly do we do with that information? How does it help if we find out that someone is really afraid their pain means something awful, or if they fear their life will never be the same again, or if they truly worry about doing movements that provoke their pain?

Truth to tell, although there have been a lot of studies examining the relevance of psychosocial risk factors, the uptake among clinicians has been fairly abysmal. This is particularly so among clinicians who work either mainly with acute musculoskeletal pain, or amongst those who are mainly involved in treated the body. One physio I know said she got the impression during her training that psychosocial factors “are the things we can blame when our treatments don’t work”.

I think part of the problem is the focus on assessment “technology”. There is a proliferation of questionnaires that can be used to help spot the person who’s likely to have difficulty recovering. We have STartBack, Orebro Musculoskeletal Questionnaire, Pain Catastrophising Scale, Tampa Scale of Kinesiophobia, Depression Anxiety Stress Scale, Pain Self Efficacy Scale – most of which are known by their abbreviations, so it’s like an alphabet soup! But despite knowing about these questionnaires, and perhaps even administering them to people we think might need assessment, once the results come in it’s pretty difficult to know what to do next.

So what if a person reports really high levels of catastrophising? Or that they’re very high on the Fear of Injury/Reinjury on the TSK? Or that they have the lowest ever score on the PSEQ? What on earth do you do to make an impact?

Some people are very actively engaged in “Pain Education”. It’s given to absolutely everyone because “the evidence says” it “works”. Pain reduces. People get engaged in their exercise. Life returns to normal.

Some people refer immediately on to a psychologist. Let them deal with the “difficult” patients.

Others just carry on as normal but in the back of their mind have the “out” that “Oh but they have yellow flags” – and drop their expectations accordingly.

To me that’s just not good enough, and it suggests to me that we need to learn more about what these measures mean – and what to do differently as a result.

There’s a couple of problems though:

  1. How do we choose who to give a questionnaire to? – do we rely on “intuition” or do we give them out to everyone?
  2. Which questionnaires do we use? There’s no “gold standard” – just a mix of various measures that tap into part of the picture…
  3. How much do we rely on strong RCT’s examining whole treatment packages, versus how much do we rely on principles of behaviour change and knowledge of the underlying theories relevant to pain and disability?
  4. What if our clinical reasoning models are completely silent on the work involved in supporting people who present with these risk factors – what if our clinical reasoning models suggest that this work is not all that important compared with the “real” work of tissues and muscles and movement?

Here are my thoughts on what we can do.

I think we should give screening questionnaires to everyone who comes in with an acute bout of musculoskeletal pain, and I think there are a couple that really work well – Orebro is clearly one of them, PCS or PASS are both useful, and I think it’s helpful to screen for mood problems. Why do I think everyone needs these? Well, it’s easier to give them to everyone than to rely on our terribly inaccurate intuition. The risk of failing to identify someone who needs more support is high (and the consequences of omitting this is serious). By routinely administering screening measures we can de-stigmatise the process (though there shouldn’t be any stigma associated with understanding that pain involves the whole person!). We can make the administration easy by integrating it within routine clinic entry process – and by using electronic forms of each questionnaire we can make entering and scoring them easy.

We then need to learn what the questionnaires actually measure – not just the total score, but the subscales as well. Then we need to use those subscale scores to understand what we need to ask the person when we see them face-to-face. This helps us begin to understand the person and how they came to develop these beliefs and attitudes, and in doing so we can develop greater empathy for their experience – and alter our treatments to reflect their needs.

For management, I think we have to, at this stage, step beyond the RCT for evidence. There’s a few reasons for this: one is that RCTs naturally omit individual responses to the treatment meaning we lost the detail as to who responds to which aspect of the treatment. Another is that RCTs often group patients together to ensure power is reached – but in doing this, omit important individual differences. And finally, each person we see is a unique individual with a unique interaction between the various factors influencing their presentation – and there are simply insufficient RCTs to account for these differences. Does this mean we stop using evidence? Oh no!! It just means we need to look at the principles behind many treatments – what are the guiding principles and why might they apply to this person at this time? Finally we need to monitor outcomes so we can establish whether our approach actually helped.

Finally, I think our clinical reasoning models need to include important aspects of treatment that we vary, often without being aware that we do.

For example, if we see someone who scores very high on the PCS and tends to ruminate or brood on the negative, we can’t go ahead and give that person the same set of exercises or activities we’d give someone who is quite confident. We’ll need to lower the physical demands, give really good explanations, take the time to explain and de-threaten various sensations the person may experience, we’ll probably need to move slowly through the progressions, and we’ll definitely need to take time to debrief and track progress.

These “invisible” aspects of treatment are, I think, often the most important parts – but they’re often not mentioned in clinical protocols, and perhaps our skill in titrating the challenges we give our patients is not well developed. These factors incorporate psychological techniques of behaviour change – things like reinforcement, motivational interviewing, problem solving, Socratic questioning, how to fade support, how to bolster confidence, how to vary the environment, and how to avoid pliance and tracking (or going along with things rather than truly integrating the learning). If we want to work with people and help them change their lives, we need to learn how people change behaviour. That means, I’m afraid, learning some psychology…!

Empathy and catastrophising influence pain inhibition


When I went to occupational therapy school I was introduced to nociception and the biological underpinnings of pain. I wasn’t, at that time, taught anything about the brain, attention, emotions or any social responses to pain behaviour. Like most health professionals educated in the early 1980’s, pain was a biological and physical phenomenon. I suppose that’s why it can be so hard for some of my colleagues to unlearn the things they learned way back then, and begin to integrate what we know about psychological and social aspects of our pain experience. Because pain is a truly biopsychosocial experience. Those pesky psychosocial factors aren’t just present in people who have difficulty recovering from pain, they’re actually integral to the entire experience.

Anyway, ’nuff said.

Today I stumbled across a cool study exploring two of the psychosocial phenomena that we’ve learned are involved in pain. The first is catastrophising. And if you haven’t got your head around catastrophising it’s probably time to do so. It’s one of the strongest predictors of disability (Edwards, Dworkin, Sullivan, Turk & Wasan, 2016). Catastrophising is the tendency to “think the worst” and consists of ruminating (brooding on), magnifying (over-estimating the negative impact) and helplessness (feeling as if there’s nothing you can do).  The second is empathy, or the ability to sense other people’s emotions, coupled with the ability to imagine what someone else might be thinking or feeling. Empathy is not the same as sympathy which seems to be about the emotions a person experiences while observing another’s emotional state. In fact, separate parts of the brain are involved in the two experiences (Cuff, Brown, Taylor & Howat, 2014).

Back to the study. This study examined conditioned pain modulation in partners observing their partner undergoing a painful experience. It was carried out by Gougeon, Gaumond, Goffaux, Potvin and Marchand (2016) in an attempt to understand what happens to the pain experience of people watching their loved ones in pain. The experimental protocol was (1) baseline; (2) assessing pain VAS 50; (3) pre-CPT heat pain testing (thermode preimmersion at a fixed temperature); (4) CPT (either at 201Cor71C); and (5) post-CPT heat testing (thermode postimmersion at the same fixed temperature). What they did was ask the participants to submerge their right hand in a freezing cold waterbath while video recording them. They then asked their partners to place their right hand in lukewarm water while watching the video recording. Participants were asked to rate their pain intensity.

What they found was the higher the catastrophizing score was, stronger was their descending pain inhibition when they were watching either themselves or their spouse in pain. In women, the more empathic the women were, the better was their descending pain inhibition when they observed their spouse in pain.

This is extraordinary. Firstly, the finding that there was a correlation between catastrophising score and descending inhibition contradicts other research studies – Gougeon, Gaumond, Goffaux, Potvin and Marchand suggest that although cognitive and emotional processes underlying catastrophising increase pain perception and decrease inhibition, their experimental design may have increased pain perception during the conditioned stimulus which may have triggered more conditioned pain modulation. They also suggest that the catastrophising level of participants increases their perceived pain, explaining why it correlates with conditioned pain modulation efficiency.

Secondly, women were more distraught than men by observing pain in others. Adopting the perspective of a loved-one elicited stronger activation in regions involved in the “pain” matrix than adopting the stranger’s perspective (Cheng et al), and the authors suggest that empathy is a powerful factor involved in pain modulation while observing someone in pain. This shows that descending inhibition is influenced by physical stimulus characteristics (such as intensity or location), as well as personal cognitive dimensions. A far cry from the notion that psychosocial factors play little part in modulating our pain experience.

What does this actually mean for us?

Well, to me it suggests that we need to be aware of our own empathic response to observing someone else who is experiencing pain. Let’s put it this way: if I’m an especially empathic person (and especially if I tend to catastrophise) and I see people who are experiencing pain in my clinical practice, my own emotional and cognitive response to seeing people may influence my behaviour and practice. For example, I might be less willing to tell people that I don’t have a way to reduce their pain. I might pursue more “heroic” healthcare – send people off for more treatments, try for longer with unsuccessful treatments “just in case”, I might even send people away from my care because I find it hard to tolerate being around someone who “doesn’t respond”.

You see, being empathic and catastrophising tends to elevate feelings of distress in the presence of pain. If we don’t have effective ways to manage our own distress when we are in the presence of someone who is indicating they’re sore, we’re at greater risk of developing burnout and of feeling frustrated (Gleichgerrcht & Decety, 2014).

For this reason I’m a fan of using mindfulness because it does help people to step back from the emotional judgements of experience, and in particular the negative impact such judgements have on both interactions and emotions (Dobkin, Bernardi & Bagnis, 2016).

… a little more about Pain Catastrophising subscales


I’ve been writing about the Pain Catastrophising Scale and how to use this instrument in clinical practice these last two posts here and here because the construct of catastrophising (thinking the worst) has become one of the most useful to help identify people who may have more distress and disability when dealing with pain. Today I want to continue with this discussion, but looking this time at a large new study where the subscales magnification, rumination and hopelessness have been examined separately to understand their individual impact on pain severity and disability.

Craner, Gilliam and Sperry looked at the results of 844 patients with chronic pain prior to taking part in a group programme (a heterogeous sample, rather than a single diagnosis, so this group probably look at lot like those admitted to high intensity tertiary chronic pain management services such as Burwood Pain Management Centre here in Christchurch).  Most of the participants were female, European/white and married, and had chronic pain for an average of 10.7 years. Just over half were using opioid medication to manage their pain.

Along with the PCS, participants also completed some very common measures of disability (Westhaven-Yale Multidimensional Pain Inventory – MPI) and quality of life (SF-36), and the CES-D which is a measure of depression.

Now here comes some statistical analysis: multiple hierarchical regression! Age, sex, duration of pain and use of opioids were entered into the equation and found to account for only 2.0% variance of the pain severity subscale of the MPI – but once the PCS was added in (subscales entered separately) an additional 14% of the variance was accounted for, but the helplessness subscale was the only one to contribute significantly to the overall variance.

When Pain Interference was  entered as the dependent variable, all the same demographic variables as above contributed a meagre 1.2% of the variance, but when the Pain Severity subscale scores were added, 25.5% of the variance was explained – while the combined PCS subscales contributed 6.5% of the variance. Again, helplessness was the only subscale to contribute to Pain Interference.

Moving to quality of life – the physical subscale of the SF-36 was used as the dependent variable, and once again the demographic variables accounted for only 1.5% variance in physical QOL, with Pain Severity accounting for 23%. PCS subscales contributed only 2.6% of the variance, with only the magnification subscale being identified as a unique contributor. When the mental health subscale was used, again demographics only accounted for 1.2% of variance, with pain severity accounting for 12.4% of the variance. This time, however, the PCS subscales contributed 19.5% of the variance with both Magnification and Helplessness contributing to the variance.

Finally, examining depression, demographics contributed a small amount of variance (3.3%), with pain severity additing 9.8% of variance. The PCS subscales were then entered and contributed a total of 21% to the prediction of depression with both Magnification and Helplessness contributing to the overall depression variance.

The so what factor

What does this actually mean in clinical practice? Well first of all this is a large group of patients, so we can draw some conclusions from the calculations – but we need to be a little cautious because these participants are a group who have managed to get into a tertiary pain management facility. They’re also a group with a large percentage using opioids, and they were pretty much all European – and from North America, not New Zealand. I’m not sure they look like the people who might commonly come into a community-based facility, or one where they’d be referred directly from a GP or primary care centre.

At the same time, while this group may not look like the people most commonly seen for pain management, they share some similar characteristics – they tend to magnify the “awfulness” of pain, and then feel helpless when their pain is bothering them. Surprisingly, I thought, ruminating or brooding on pain wasn’t a unique contributor and instead the helplessness scale contributed the most to pain severity, pain-related interference (disability associated with pain), poor mental health quality of life, and low mood, while magnification scale contributed to poorer physical health quality of life, mental health quality of life and low mood.

What this means for practice

The authors suggest that the construct measured by the helplessness subscale might be a factor underlying poor adaptation to life’s difficulties in general, leading to passivity and negative emotions. They also suggest that magnification might be a unique contributor to perceiving obstacles to doing the things we need to do every day, while hopelessness might mean people are less likely to participate in enjoyable activities and then in turn contribute to feeling low.

Importantly, the authors state: “We offer that simply collapsing the 3 dimensions of this phenomenon (ie, rumination, magnification, helplessness) may actually conceal nuanced relationships between specific dimensions of catastrophizing and outcomes that would might inform treatment approaches.” Looking at the overall scores without thinking about the subscales is going to give you less information to use for individualising your treatment.

In a clinical setting I’d be reviewing the individual subscales of the PCS alongside both disability and mood measures to see if the suggested relationships exist in the scores this person has given.

I’d be taking a look at the repertoire of coping strategies the person can identify – and more, I’d be looking at how flexibly they apply these strategies. Extending the range of strategies a person can use, and problem-solving ways to use these strategies in different activities and contexts is an important part of therapy, particularly occupational therapy and physiotherapy. Another approach you might consider is helping people return to enjoyable activities that are within their tolerance right here, right now. By building confidence that it’s possible to return to things that are fun we might counter the effects of helplessness, and help put pain back where it belongs – an experience that we can choose to respond to, or not.

I’d also be taking a look at their tendency to avoid feeling what their pain feels like, in other words I’d like to see if the person can mindfully and without judging, complete a body scan that includes the areas that are painful. This approach is intended to help people notice that alongside the painful areas are other nonpainful ones, and that they can successfully be with their pain and make room for their pain rather than attempting to block it out, or over-attend to it. The way mindfulness might work is by allowing people to experience the sensations without the judgement that the experience is bad, or indicates some terrible catastrophe. It allows people to step back from the immediate reaction “OMG that’s BAD” and to instead take time to view it as it actually is, without the emotional halo around it.

Pain catastrophising is a useful construct – but I think we need to become more nuanced in how we use the scores from the questionnaire.

Craner, J. R., Gilliam, W. P., & Sperry, J. A. (2016). Rumination, magnification, and helplessness: How do different aspects of pain catastrophizing relate to pain severity and functioning? Clinical Journal of Pain, 32(12), 1028-1035.

What do we do with those questionnaires?


Courtesy of many influences in pain management practice, you’d have to have been hiding under a rock or maybe be some sort of dinosaur not to have noticed the increasing emphasis on using questionnaires to measure factors such as pain catastrophising, depression or avoidance. The problem is I’m not sure we’ve all been certain about what to do with the results. It’s not uncommon for me to hear people saying “Oh but once I see psychosocial factors there, I just refer on”, or “they’re useful when the person’s not responding to my treatment, but otherwise…”, “we use them for outcome measures, but they’re not much use for my treatment planning”.

I think many clinicians think psychosocial questionnaires are all very well – but “intuition”  will do “…and what difference would it make to my treatment anyway?”

Today I thought I’d deconstruct the Pain Catastrophising Scale and show what it really means in clinical practice.

The Pain Catastrophising Scale is a well-known and very useful measure of an individual’s tendency to “think the worst” when they’re considering their pain. Catastrophising is defined as “an exaggerated negative mental set brought to bear during actual or anticipated painful experience” (Sullivan et al., 2001). The questionnaire was first developed by Sullivan, Bishop and Pivik in 1995, and the full copy including an extensive manual is available here. Keep returning to that page because updates are made frequently, providing more information about the utility of the measure.

The questionnaire itself is a 13-item measure using a 0 – 4 Likert-type scale from 0 = “not at all” to 4 = “all the time”. Respondents are instructed to “indicate the degree to which you have these thoughts and feelings when you are experiencing pain”.

There are three subscales measuring three major dimensions of catastrophising: rumination “I can’t stop thinking about how much it hurts”; magnification “I worry that something serious may happen”; and helplessness “It’s awful and I feel that it overwhelms me”.

To score the instrument, simply sum all the responses to all 13 items, but to get a better idea of how to help a person, the subscale calculations involve the following:

Rumination: sum items 8,9,10, and 11

Magnification: sum items 6,7, and 13

Helplessness: sum items 1,2,3,4,5, and 12

There’s not a lot of point in having numbers without knowing what they mean, so the manual provides means and standard deviations relating to a population individuals with injury leading to lost time from work in Nova Scotia, Canada.

thingClinicians are typically interested in whether the person sitting in front of them is likely to have trouble managing their pain, so the manual also provides “cut off”scores for what could be described as “clinically relevant” levels of catastrophising. A total score of 30 or more is thought to represent the 75th percentile of scores obtained by individuals with chronic pain.

The “so what” question

Cutting to the chase, the question is “so what”? What difference will getting this information from someone make to my clinical reasoning?

Leaving aside the enormous body of literature showing a relationship between high levels of catastrophising and generally poor responses to traditional treatments that address pain alone (including surgery for major joint replacement, recovery from multiple orthopaedic trauma, low back pain, shoulder pain etc), I think it’s helpful to dig down into what the three subscales tell us about the person we’re working with. It’s once we understand these tendencies that we can begin to work out how our approach with someone who has high levels of rumination might differ from what we’ll do when working with someone who has high levels of helplessness.

As an aside and being upfront, I think it’s important to remember that a questionnaire score will only tell you what a person wants you to know. Questionnaires are NOT X-rays of the mind! They’re just convenient ways to ask the same questions more than once, to collect the answers and compare what this person says with the responses from a whole lot of other people, and they allow us to organise information in a way that we might not think to do otherwise.  I also think it’s really important NOT to label a person as “a catastrophiser” as if this is a choice the person has made. People will have all sorts of reasons for tending to think the way they do, and judging someone is unprofessional and unethical.

Rumination

Rumination is that thing we do when a thought just won’t get out of our mind. You know the one – the ear worm, the endless round and round, especially at night, when we can’t get our mind off the things we’re worrying about. If a person has trouble with being able to drag his or her attention away, there are some useful things we can suggest. One theory about rumination is that it’s there as a sort of problem solving strategy, but one that has gone haywire.

Mindfulness can help so that people can notice their thoughts but not get hooked up into them. I like to use this both as a thought strategy, but also as a way of scanning the body and just noticing not only where the pain is experienced, but also where it is not.

“Fifteen minutes of worry” can also help – setting aside one specific time of the day (I like 7.00pm – 7.15pm) where you have to write down everything you’re worried about for a whole fifteen minutes without stopping. By also telling yourself throughout the day “I’m not worrying about this until tonight” and afterwards saying “I’ve already worried about this so I don’t need to right now”, worrying and ruminating can be contained. By being present with the thoughts during that 15 minutes, the threat value of the thought content is also reduced.

Magnification

This is the tendency to think of the worst possible thing rather than the most likely outcome, and it’s common! Magnification can really increase the distress and “freeze” response to a situation. If a person is thinking of all the worst possible outcomes it’s really hard for them to focus on what is actually happening in the here and now. There’s some adaptive features to magnification – if I’ve prepared for the worst, and it doesn’t happen, then I’m in a good situation to go on, but in some people this process becomes so overwhelming that their ability to plan is stopped in its tracks.

Once again, mindfulness can be really useful here, particularly paying attention to what is actually happening in the here and now, rather than what might happen or what has happened. Mindful attention to breathing, body and thoughts can help reduce the “freeze” response, and allow some space for problem solving.

Of course, accurate information presented in nonthreatening terms and in ways the person can process is important to de-threaten the experience of pain. This is at the heart of “explain pain” approaches – and it’s useful. What’s important, however, is to directly address the main concern of the person – and it may not be the pain itself, but the beliefs about what pain will mean in terms of being a good parent, holding down a job, maintaining intimacy, being responsible and reliable. It’s crucial to find out what the person is really concerned about – and then ensure your “reassurance” is really reassuring.

Helplessness

Helplessness is that feeling of “there’s nothing I can do to avoid this awful outcome so I won’t do anything”. It’s a precursor to feelings of depression and certainly part of feeling overwhelmed and out of control.

When a person is feeling helpless it’s important to help them regain a sense of self efficacy, or confidence that they CAN do something to help themselves, to exert some sort of control over their situation. It might be tempting to aim for focusing on pain intensity and helping them gain control over pain intensity, but because it’s often so variable and influenced by numerous factors, it might be more useful to help the person achieve some small goals that are definitely achievable. I often begin with breathing because it’s a foundation for mindfulness, relaxation and has a direct influence over physiological arousal.

You might also begin with some exercise or daily activities that are well within the capabilities of the person you’re seeing. I like walking as a first step (no pun intended) because it doesn’t require any equipment, it’s something we all do, and it can be readily titrated to add difficulty. It’s also something that can be generalised into so many different environments. In a physiotherapy situation I’d like to see PTs consider exercises as their medium for helping a person experience a sense of achievement, of control, rather than a means to an end (ie to “fix” some sort of deficit).

To conclude
Questionnaires don’t add value until they’re USED. I think it’s unethical to administer a questionnaire without knowing what it means, without using the results, and without integrating the results into clinical reasoning. The problem is that so many questionnaires are based on psychological models and these haven’t been integrated into physiotherapy or occupational therapy clinical reasoning models. Maybe it’s time to work out how do this?
