Experiential avoidance – and persistent pain


Most of us will recognise that when we experience a pain, we firstly notice where it is, and the sensory qualities of it. We automatically make judgements about that pain – some of this judgement is about whether we recognise this pain (have we had it before?), some is about whether it’s important enough to interrupt what we’re doing (should I drop this hot cup of coffee, or can I hold onto it long enough to place the cup carefully on the bench), and some is about how we feel emotionally (yes, swearing is common when we smack our thumb with a hammer!).

In our response to acute pain, we often want to avoid or escape whatever we think gave us the pain – unless, of course, it’s something we choose to do even though it hurts. You know, things like lifting really heavy weights, running distances, taking rugby tackles, eating chilli! But in most cases where the pain is unexpected we’re inclined to want to make it stop, get away from the thing that probably caused it, and take a few minutes (or longer) to not do the things that make it worse. So we avoid walking on a newly sprained ankle and we don’t keep poking and prodding at a cut or a bruise.

Avoiding is quite common and even helpful when we experience the initial onset of a pain.

So why do we talk about “fear avoidance” as if it’s a bad thing?

Well, it’s because avoiding beyond a useful period of time often leads to ongoing problems. Some of these problems are possibly over-stated: things like “deconditioning” are probably not as much of a problem as we once thought (see Andrews, Strong & Meredith, 2021; Tagliaferri, Armbrecht, Miller, Owen et al, 2020). While other forms of avoidance may never even be considered.

What do I mean?

For a moment, think of a “weekend warrior”. The kind of person who heroically plays sport on a Saturday, trains once or twice during the week, and otherwise works hard and plays hard. Let’s think of this person as a male, perhaps in his late 30’s, thinks of himself as a hard worker and a family man. When he sprains his wrist after a particularly hard tackle in a weekend rugby game, he’s the kind who shrugs it off, and just keeps going. After a few weeks and his wrist doesn’t get much better, he heads off to see his local physio.

We wouldn’t usually think of him as an “avoider”. He’s not pain-avoidant, but sometimes because he doesn’t stop to take care of his wrist sprain, he ends up with a more troublesome injury. He might even develop a “boom and bust” pattern of activity: on a day he’s feeling good he’ll push through, but then his wrist starts playing up and he needs to take a day or two off.

I’m going to call it like I see it: this bloke is avoiding. What he’s avoiding is the experience of being vulnerable, of seeking help, of being advised to stop pushing himself for a day or so.

You see, experiential avoidance is what we do to avoid feelings (emotions) and actions that we don’t like or don’t want.

We see experiential avoidance most often described in pain research in the group of people who don’t resume their usual daily activities in part because they’re afraid of their pain. Or they’re afraid of what their pain might mean, or the effect of their pain on other things they need or want to do. For example, Angelina (see here) might be worried about the effect of pain on her sleep. And we’re reasonably OK with offering these people some information about what might be going on in their tissues, and that the relationship between pain and what’s going on in the tissues might not be as straightforward as it is when we hit our thumb with a hammer.

What we might be less aware of, and perhaps struggle to deal with is when a person appears to be doing the right things, like they’re remaining active and staying at work, but might be overdoing it. What might this person be avoiding? Perhaps, as I’ve suggested in the example above, it’s about avoiding feeling vulnerable, feeling like he’ll be told to slow down for a bit. Slowing down might be a sign, at least to our weekend warrior, that he’s not as young as he used to be. Perhaps he’s afraid of stopping because that means his busy mind can start to plague him with unhelpful thoughts about things he’s worrying about.

Experiential avoidance, like avoidance when a painful injury first happens, isn’t always a negative. When it’s used as the key strategy for life, indiscriminately and with an eye only to short-term benefits and not long-term consequences, then it’s not so good.

You see I hope we can help people to develop psychological flexibility: the ability to choose a response to any given situation that maintains moving towards what matters even if this means doing what feels odd or even a backwards step.

I also think we might benefit from developing psychological flexibility ourselves as clinicians. If we continue using the same old, same old strategy even if the results aren’t what we hoped for, we’re not helping anyone.

Your patient has psychosocial risk factors: what now?


Congratulations! You’re an insightful clinician who’s offered your patient a screening assessment to find out if she or he has psychosocial risk factors – and yes! they do! Well done. Now what?

Do you…

  • send your patient to the nearest psychologist?
  • spend at least one treatment session offering pain neurobiology education?
  • scramble to find a “psychologically informed physio” to send them to, because it takes really highly trained and special clinicians to work with these people
  • give your patient the same exercise prescription you were going to anyway because, after all, they still have things going on in their tissues (or is it their nervous system? I forget – whatever, they just need to move, dammit!)
  • throw your hands up in horror and say “I never wanted to deal with people in pain anyway!”

You’d have to be hiding beneath a rock to avoid learning that people with musculoskeletal pain with psychosocial risk factors such as feeling that back pain is terrible and it isn’t going to get better, believing that it’s not safe to move or exercise with back pain, having worrying thoughts going through their mind, or not enjoying things very much should have special attention when they seek help for their pain. And we’ve all read studies showing that many of our frontline clinicians who see people with musculoskeletal pain aren’t comfortable, confident or clear about what to do with people who are, frankly, scared and distressed.

Papers like Caneiro, Bunzli & O’Sulllivan’s (2021) Masterclass clearly show that messages people with pain get told include avoiding certain movements to prevent damage, being advised that special exercises ‘protect’ the body, and that clinicians believe that certain postures and movements are inherently unsafe (bending, lifting with a rounded back). At the same time, Sajid, Parkunan & Frost (2021) found that only 11.8% of people referred by GPs for musculoskeletal MRIs had their mental health problems addressed, while only 16.7% of the MRI results were correctly interpreted by GPs and in 65.4% of cases were referred for “spurious overperception of surgical targets.”

Worse, Nicola, Correia, Ditchburn & Drummond (2021) conducted a systematic review of the effects of pain invalidation on individuals – invalidation from family, friends and healthcare individuals, and the person themselves. They found five themes: not being believed, lack of compassion, lack of pain awareness and understanding, feeling stigmatised and critical self-judgement. Perceived social unacceptability of experiencing pain was found to have an impact on the emotional state and self-image of those with persistent pain. Ya think?!

If I return to the case I presented last week, Angelina, a pretty common case of someone with a neck pain who is having trouble sleeping and generally handles her pain independently, we could assume that she doesn’t have significant psychosocial risk factors. After all, she’s managing to stay working, does a bit of self-help, and she’s not depressed though she’s a bit irritable.

What would you do?

I guess my first thought is: would Angelina even get a screening assessment to see whether she has any psychosocial risk factors? Might she present superficially well enough for her therapist to think she’s fine, let’s just treat the neck?

Of all the neck pain treatments available, what would she be given? And what might she be told about the rationale for that treatment? A recent systematic review with meta-analysis pointed out that while specific exercises helped in the short to medium term, the quality of that evidence was low (Villaneuva-Ruiz, Falla, Lascurain-Aquirrebena, 2021), while a systematic review with network meta-analysis of 40 RCTs found “There is not one superior type of physical exercise for people with chronic non-specific neck pain.
Rather, there is very low quality evidence that motor control, yoga/Pilates/Tai Chi/Qigong and strengthening exercises are equally effective.” (de Zoete, Armfield, McAuley, Chen, & Sterling, 2020).

More than this: would her sleep and relationship concerns be discussed? What about her safety while driving? How about how she manages her work, and her belief that perhaps her pain is happening because of a period at work where she wasn’t positioned “correctly”?

You see, at the moment in our musculoskeletal treatment literature, the focus has been almost entirely on grouped data. And this, folks, is where Steven Hayes points out that the ergodic theorum is violated. Ergodic theory is “…the idea that a point of a moving system, either a dynamical system or a stochastic process, will eventually visit all parts of the space that the system moves in, in a uniform and random sense. This implies that the average behavior of the system can be deduced from the trajectory of a “typical” point. Equivalently, a sufficiently large collection of random samples from a process can represent the average statistical properties of the entire process.” (I stole that from https://en.wikipedia.org/wiki/Ergodicity).

Hayes, Hofmann & Ciarrochi (2020) point out that “We cannot assume that the behavior of collectives (e.g., a volume of gas) models the behavior of an individual element (e.g., a molecule of gas) unless the material involved is “ergodic” and thus all elements are identical and are unaffected by change processes.” Humans are not ergodic (only a few noble gases are…) and what this means is that “statistical techniques based on inter-individual variation cannot properly assess the contribution of given elements to phenotypic change.” In other words: humans actively respond and change to what they’re exposed to – each of us presents to treatment with our own incredibly unique range of responses and past history, and these influence how we respond to a treatment. And perhaps this explains why most of our treatments (RCTs, using grouped data and uniformly applied and consistent treatments) particularly for persistent pain problems end up showing pretty small effect sizes. We’re violating the assumptions of the ergodic theorum. What we need are more sophisticated ways to analyse the impact of any therapy, and far fewer algorithms and cookie cutter treatments.

Where does this leave us? I have loads of ideas about where to from here, but not nearly enough space today to write about them!

My first suggestion is to avoid blindly following a treatment algorithm that fails to support YOU to sensitively and reflexively offer treatments that fit for your patient.

My second is to avoid measuring the impact of what you do only at the end of treatment (or worse, not at all!). Measure often, and measure things that matter – either to how you get to the end outcome, or that the person values. Or both.

And third: Get reading outside of your profession. Dig into psychology (I especially recommend Hayes); look at sociology (try Jutel); anthropology (try Sarah Pink’s “Sensuous futures: re-thinking the concept of trust in design anthropology”); make 2022 the year that you lean into uncertainty. I know the past two years have been incredibly unsettling – but this is the perfect time to continue on this journey into new ideas, fresh concepts, and ambiguity.

Making first contact: what to do with all that information! Part 3


In my last post I described the “4 P” model (sometimes called the 5P!) of formulation for pain. In today’s post I want to talk about an integrated approach for a team.

Teamwork in pain management is an enormous thing – IASP (International Association for the Study of Pain) endorses multidisciplinary (I prefer interprofessional) teamwork but gives little information on how teams best work together. In fact, research exploring teamwork processes in pain management is remarkably absent, even though there’s considerable research elsewhere in healthcare showing that effective teamwork is quite distinct from being an effective solo clinician. The processes of coming together, learning about one another and what each person and profession contributes, learning how to make decisions, how to negotiate differences of opinion, to trust one another: all of these have been explored in other health settings, but not in pain management ones. This matters because of all the areas in healthcare, pain management presents us with the most complex inter-related problems where the model of pain adopted by a team must be consistent or the person with pain will likely feel utterly confused.

’nuff said. Let’s take a look at a team mental model of pain, because this is where learning from one another and across professions becomes “live”.

The basic assumption for the whole team must be that pain is a multifactorial experience, influenced by (broadly) biological, psychological and social elements. In other words, a team won’t work well if some of the members think that pain can be “fixed” by addressing only one piece of the puzzle. Even in acute pain, the team needs to recognise that what a person believes is going on, the meaning they draw from the experience, the influence of others (the family, hospital staff, community) will make a difference to the person’s distress and disability. Context always matters and people always bring their previous experiences (either personal or drawing from what they’ve seen/heard from others, including media) with them when they’re in pain.

If the team takes this idea on board, then the weight that’s placed on the various factors contributing to distress and disability should be equal, at least initially. For example, although anxiety might be a key influence in one person’s pain experience, this shouldn’t be valued above possible biological factors. Each contributing factor needs to earn its way into the overall formulation, and it’s only from reviewing the formulation as a whole that it’s possible to determine where to begin with treatment.

This sounds complicated – and it can be in some cases! But it is really a mindset rather than being horribly complex. If we hold each piece of the puzzle lightly, look to the relationships between each piece, then we can begin to see how one factor influences another. And teams can, if they share their ideas, put the pieces together much more effectively than any single person can – even the person with pain.

Yes, the person with pain IS part of the team – always. How else will the team know they’ve been effective?

Teams form a mental model of what each other knows, what the team (as a whole) thinks matters, and who in the team might offer the mix of skills the person needs. This mental model doesn’t happen instantly: you can’t put six clinicians in a room and an hour later expect them to have a common understanding of pain, each other, and what the team can do. There’s good research showing that teams need time together – even virtual teams (Maynard & Gilson, 2021) – and that frequently changing team members reduces the teams’ effectiveness (Bedwell, 2019; Williams & Potts, 2010). Mental models emerge as teams share knowledge – the problem is that group members often share knowledge that is common, rather than unique information that could be the linchpin to an effective decision (Levine, 2018).

In my experience, and reading through an enormous amount of research, the most commonly adopted model in persistent pain management is a cognitive behavioural approach. Now this is not “CBT” the therapy, but instead an approach that recognises:

People are active processors of information and not passive reactors.

Thoughts (e.g., appraisals, expectations, and beliefs) can elicit and influence mood, affect physiological processes, have social consequences, and also serve as an impetus for behavior; conversely, mood, physiology, environmental factors, and behavior can influence the nature and content of thought processes.

• Behaviour is reciprocally determined by both individual and environmental factors.

People can learn more adaptive ways of thinking, feeling, and behaving.

People should be active collaborators in changing their maladaptive thoughts, feelings, and behaviour. (Turk & Flor, 2013)

We might disagree on how these points might be operationalised, and treated, but a team should have something like this as a critical understanding of how the factors influencing a person’s distress and disability might fit together.

I’ve written plenty of times about the formulation approach that I’ve often used – here and here – and I’ll show you another ACT-based formulation next week. In the meantime, perhaps it’s time to consider how well you and your team know one another, and consider whether you have enough trust in one another to debate issues (not people), bring unique information (rather than shared), and collaborate rather than compete?

Making first contact: What to do with all that information! part 2


Last week I described some of the reasons for using a case formulation approach when working through initial assessment information, and today I’m going to describe one approach for organising a formulation. This is the “4 P” formulation, and it’s one that’s often used in mental health (Bolton, 2014).

In the 4 P model, there are four questions to ask yourself:

  1. Preconditions – Why is this person vulnerable to this problem?
  2. Precipitating factors – Why now? This can mean “why is this person having symptoms now?” or “why is this person presenting to this person for treatment right now?”
  3. Perpetuating factors – Why is this person still ill?
  4. Protective factors – Why is this person not more ill?

Remembering that people are whole people, and that pain is always multifactorial, this formulation approach incorporates diagnostic information (disease) alongside a person’s response to disease (illness). The two facets of “being unwell” go together – but not synchronously. We can have a disease and be oblivious to it (think of many forms of cancer, hypertension, Type 2 diabetes, osteoarthritis…and even Covid-19). Once we begin to experience symptoms and decide that this is not “normal” we call it illness. And if symptoms and signs begin to impinge on what we can and can’t do in life, we can call this disability or functional limitations. These in turn (more or less) influence participation in community life. The relationships are not straightforward, and this is partly why a formulation can be so helpful. Formulations help us explore – in collaboration with the person – why is this problem such a problem? – whether it’s simply the presence of pain, or more related to the disability and distress that pain is posing for the person.

Preconditions include biological factors such as gender, ethnicity, and age. Preconditions also include psychological factors such as previous experiences in life, prevailing beliefs, emotional reactivity, and attention. Social factors such as employment status, social connection, stigma, socio-economic status, family and living situation are all contributors to a person’s vulnerability to the problem they’re presenting with. In our pain formulations, we know about many of these preconditions that make the people we see vulnerable to having trouble with their pain.

Precipitating factors can be considered in several ways. I like to consider behavioural antecedents for seeking help – what’s been happening in the immediate weeks before a person seeks help – as well as antecedents to the onset of symptoms. For example, people might wait for some weeks before seeking help for a back pain because “it usually settles down” – and this suggests to me that their current episode hasn’t settled down, and they have some thoughts or worries about why. Others might be seeking help because of insurance or workplace requirements where, if they don’t seek help and have the problem recorded, they may not get cover for treatment if the problem reoccurs. Some might be seeking help because their partner or family member is worried, or because they read something in the media or online. I also ask about what was happening at the time the symptoms started. Sometimes this is about an unusually busy time (at work or home), a change in activity level, a new tool or piece of equipment, a new manager or coworkers, perhaps a new daily routine, or a change in living circumstances. While these factors may not be directly causal (biologically) the meaning of these events is valuable because they inform me of the person’s beliefs about their problem.

Perpetuating factors are again, multifactorial and often unrelated to the factors that precipitated the problem. There could be factors associated with disuse influencing changes to the tissues and neurobiology; there could be steps the person has taken to deal with the problem that impact on how quickly it resolves such as using NSAIDs or strapping/wrapping, wearing splints, changed movement patterns. Some of the factors are likely to be beliefs about what’s going on and what should be done about it – like “all the pain must be gone before I start back at work”, or “it’s damaged so I need surgery”. Others could be instructions from people (or held in the community at large) about what to do, like resting, moving in particular ways, or when to seek treatment. Some can be how others respond to the person, like getting irritated because the person isn’t 100% “yet”, or mollycoddling the person (wrapping them up in cottonwool and not letting them do things again). Workplace factors like policies not allowing a person back “until fully fit” or “there are no light duties” also contribute to trouble resuming normal activities.

Protective factors help explain resilience, or strengths the person has that help them maintain well being in the face of this problem. They can be attitudes and practices of the person like believing the body is good at recovering, or maintaining healthy eating and sleeping. They may be factors such as the person’s age, gender, general health. They can include the ability to get to and from treatment (and pay for it), the person’s social supports, their relationships with other health professionals, perhaps strategies they’ve used for other problems (including similar ones to this event) that they haven’t thought to use for this one.

The 4P approach has multiple variants. Some include “the Problem” and call it a 5P model. Some are explicitly tied to a theory of human behaviour (such as a CBT model, ACT model or applied behaviour analysis). Some are entirely developed from the person’s own words and experiences, while others draw on reports from other team members, or previous interactions. The over-riding themes of all of these are that a formulation is developed in collaboration with the person, and considers the whole person in their own usual context.

Next time I’ll look at another formulation approach, and discuss it in relation to teams and how they might use it to form a “team model” of pain and musculoskeletal problems.

Thought experiment: Would therapists be out of a job if we could “fix” persistent pain?


Every few years someone, somewhere, announces that “it won’t be long before we have a treatment to rid the world of persistent pain.” And there’s a hiss and roar to celebrate this momentous finding, and much ado about how wonderful it will be.

I’m still waiting. BUT I thought it might be an interesting thought experiment to wonder what might happen if a “cure” was available for fibromyalgia.

As readers will know, I have lived with what eventually was named “fibromyalgia” since my early 20’s, and probably longer. I’ve dabbled in various treatments over the years but sadly, nothing but good clean living has helped (by which I mean early to bed, good diet, maintain healthy movement, manage stress, have good friends to connect with, play, have fun). So I would dearly love a treatment that would remove the constant aching, reduce the prolonged DOMs, keep a lid on delayed recovery after injury, and generally offer me a life relatively “normal.”

I am definitely pro-pain reduction and pain treatment. I just haven’t found anything that changes mine.

We have had some spectacular developments in therapies over the past 25 years – particularly in the inflammatory rheumatological diseases like ankylosing spondylitis, rheumatoid arthritis and ulcerative colitis. Treatments with anti-TNF alpha biologicals means that my partner who lives with anky spond now has normal C reactive protein levels, no pain, the disease activity has stopped, and he’s tickety-boo.

So why am I just a tad reserved about the notion of a “fix” based on new discoveries about mechanisms associated with neuropathic and nociplastic pains? Why am I just a little skeptical of a new psychological study showing outstanding results (Ashar, Gordon & Schubiner, 2021)? Am I just worried I’ll be out of a job if there’s an effective treatment?

Nope.

You see, even though some people like my Manly Jack have had a wonderful response to treatment for inflammatory disease, there are many more who have not. Or, who have significant reductions in inflammation – but not to “normal” levels, and accompanied by complications/adverse effects, and, in many instances, continued pain. Why is that? Well – I think it’s because while treatments target mechanisms, people are enormously variable in both biology and more importantly, psychology and sociology.

And it’s these last two that have been identified as amongst the most important contributors to ongoing disability and limited participation.

Now the social deserves a little attention. Drug developments are not cheap. The medication my partner uses is extremely expensive – NZ$1200 every two weeks. Luckily for us, this drug is fully funded by the NZ Government. There’s an economic argument for having meds like these publicly funded – without this drug, it would have been very difficult for my man to carry on working. He was having trouble rolling over in bed at night, had trouble coughing, couldn’t inhale fully, and walked like a little old man. He’s now fit as a buck rat and pays his taxes because he’s working.

The problem is, as we can see from the Covid vaccination roll-outs world-wide, people and countries without resources have less access to effective treatments. Even in NZ where we don’t have the “vaccine hesitancy” of other countries, the people who are least likely to be vaccinated right now are those who have trouble traveling to a centre, who don’t feel “at home” in healthcare, who are hard to reach, perhaps not very literate, don’t speak English or te reo Māori. The NZ government is working incredibly hard to ensure the vaccine is given to these people, and I’m proud of the variety of ways they’re doing so.

But spare a thought for countries where there is no relative affluence. Where other countries don’t have the will to help. Where infrastructure is poor. Where women, children, and people from different cultural backgrounds or religions are discriminated against. In these countries, vaccinations are very slow to reach those in need.

So one risk from a fancy new treatment is that people who need it but can’t afford it, don’t trust healthcare (who would after the stigmatisation so many people receive?), and people who are from countries where the rest of the world doesn’t help out – they risk missing out.

Another risk is that while pain might be reduced or even eliminated, these address only the biology, and people are people, and pain is multidimensional. People remember what it was like to be in pain. People have their own narratives about what’s going on to create their pain. We all learn from our experiences, and beliefs, attitudes, emotions, the influence of others around us, the communities and families and workplaces we come from, all of these have an effect on “what it is like to be experiencing pain.”

We know that people who have completely successful joint replacements without pain, don’t resume the activities they were doing before their joints became painful (see my last blog post). People successfully treated with biologicals still hold fears about future harm that developed before they got their treatment. We know that many people take years before being diagnosed and treated successfully – and that’s a long time to develop beliefs, habits, routines and relationships that don’t support recovery. We also know the trauma of unhelpful and stigmatising healthcare interactions can live long, even after successful care.

Resuming daily life and valued activities is integral to pain rehabilitation. Helping people safely do what matters to them in their life contexts is still needed. In the enthusiasm for applauding treatment advances, we need to remember that people are more than the sum of their diagnoses, more than their biology, and our societies are not fair.

Adam’s slow recovery


Not long ago I wrote about Adam Meakins back pain, and the astonishing response he’s had from fellow clinicians as he’s documented his recovery. Sadly, the polarised views of how therapists should approach a person with low back pain show me just how appallingly badly we adhere to low back pain guidelines… and worse, the kind of language and attitudes shown to a colleague who knows what he’s doing, demonstrates why change is so very slow.

What do I mean? Well, Adam has been following evidence-based low back pain guidelines that haven’t really changed a great deal since the advent of New Zealand’s “Yellow Flags” and guide to low back pain published waaaaay back in 1997. I’ve jumped to the NICE guidelines, as an example of one guideline, but you could look to many others.

NICE suggest these steps:

Assess for alternative diagnoses – in particular, “cancer, infection, trauma or inflammatory disease such as spondyloarthritis”

Risk assessment – basically, sorting people into those who are pretty OK with their pain, non-distressed and recommending those people receive “reassurance, advice to keep active and guidance on self-management.”

If Adam was distressed, or had a whole lot of risk factors for ongoing disability, then he might benefit from “more complex and intensive support for people with low back pain.” And yes, this mentions exercise programmes, manual therapy, psychological approaches.

Imaging – is not recommended, with imaging only used if the result is likely to change management.

Treatment – self-management, no orthotics or belts, no traction, and only offer manual therapy as part of an overall package that includes exercise.

No acupuncture, no electrotherapy.

Maybe use psychological therapies in conjunction with exercise.

Add in some NSAIDs

And don’t do much else…

In other words – exactly what Adam has been doing.

Why are there so many clinicians offering unsolicited opinions, without examining Adam, and without listening to his preferences, and without referring to the evidence?

What does this say about our clinical practice? What does it say about our confidence? What does it say about knowledge translation?

Most of all, what does this DO to the people we hope to help?

Seriously, folks. Watching the responses gives me nightmares.

I’ve been working in this field for 30 years now, and saying essentially the same thing about low back pain management for most of those years. I worry that an enormous business is built around scaring people, offering treatments with limited effect, for a condition that is common and responds well to doing normal movements.

In fact, one gripe I do have with the NICE guidelines is that they utterly and completely ignore daily life activities that a person needs to return to, and quickly. There’s nothing on managing sleep – and Adam’s described really rotten sleep until two days ago. There’s nothing on how to manage washing yourself, driving your car, sitting at a desk, doing the grocery shopping, preparing a meal, care for kids (or older parents) – absolutely nothing on the daily life activities that people need and want to do.

But, then again, I would say this – occupational therapists are the profession concerned about daily doing. The context of every day life. Knowledge translation from clinic/gym/exercise to what people actually do in their daily routines. It looks oh so simple – until you have to do it.

Back to Adam’s slow recovery. As I’ve watched Adam’s videos, I’m struck with the thought that many people just don’t know what to say – and so offer advice because that’s one way to deal with their own disquiet at helplessness. Clinicians, we need to develop better skills at managing our OWN emotional responses. We need to develop greater skills at sitting with our uncertainty. We need to stop leaping in with unsolicited advice that we offer just because we’re not comfortable doing nothing.

Could we just, for a moment, stop thinking about our reactions – and listen to what Adam (and I’m sure a whole bunch of our patients, too) says he wants? Listening means stopping that inner voice that’s got the “good” advice. It means really hearing what a person says. And only formulating a verbal response after we’ve digested the meaning the person is trying to convey.

Kia kaha Adam. You’re a brave man, a strong man, and I have much respect for you.

“Just a little scratch”


If you’ve had a blood test, flu jab or Covid-19 vax (please do, not just for you but for the vulnerable) you’ll probably have heard those words “Just a little scratch” then the needle goes in and ouch! I’ve wondered why phlebotomists and vaccinators use those words: is it to reduce the pain? give you some warning so you don’t pull away? why use the word “scratch” when it’s not a scratch?!

I suspect, though I haven’t read up on it, that the reason people say “just a little scratch” is to influence expectancies. Expectancies are defined as “cognitions regarding the probability of future experiences, events, and behaviour” (Peerdeman, van Laarhoven, Peters & Evers, 2016). In other words, what we expect to experience, happen or do influences what we actually experience, what happens, and what we do. Expectancies are really important when we consider placebo – and nocebo. Despite commentators who don’t consider placebo to be a thing (the response to being in a treatment ritual, over and above the effects of any active therapeutic agent), in pain, it is most definitely a thing, and one we need to be aware of as clinicians.

Back to expectancies.

Mostly, what we expect is what we experience. If we expect something to REALLY HURT then it’s likely to REALLY HURT! But what happens when we don’t expect something and it happens? Or when we expect something not to really hurt, but it actually does?

Peerdeman, Geers, Porta, Veldhuijzen and Kirsch (2021) investigated this mismatch between what we expect and what actually happens. It’s fascinating because the results weren’t quite in line with what the researchers thought…

What did they do?

The authors selected 82 healthy adults, aged between 18 and 30, with no health problems (physical or psychologist), no chronic pain, no current pain, no medications, no pacemakers, and no pregnancy. The participants weren’t allowed to use any medication, alcohol or other drugs in the 24 hours before the experiment.

Two experimenters undertook the experiments – one wasn’t aware of who was getting what, while the other was unaware of what was getting what until just before she gave the verbal suggestion. The experimenter who was blinded left the room before the second one gave the suggestion, in order to remain blinded throughout.

The participants were wired up to record heart rate, skin conductance, and then thermal and nociceptive perception thresholds were identified – at least in part to give participants a chance to get used to the heat stimulus. The experimenters went in to increase the heat to identify the temperature where participants indicated the pain was “moderately high” (who volunteers for these experiments? Oh – they recruited from around the university and on social media...). Then the experimenters got to work: participants were randomised to get either a suggestion of “no pain” (they’d already had three occasions where the thermal stimulus wasn’t painful, and three where it was), or a suggestion of moderately high pain. Then the stimulus was applied four times, with participants having to rate the expected pain intensity, how certain they were of this prediction, and how afraid they were. Afterwards, they were asked to rate pain intensity and unpleasantness.

For all the details of this experiment, head to the paper itself – it’s very detailed, and could be replicated.

Results

One person dropped out before the trial began – it was too painful – leaving 81 people remaining. The average age was 22 years, but the investigators don’t report gender.

When people were told “it’s not going to hurt” participants rated the pain lower than those who were told it was going to hurt, and while the ratings changed depending on what they experienced, when it was again suggested they’d feel no pain – again their pain ratings were lower than expected. Who knew pain intensity could vary so much? Reported pain intensity in the people who were told they wouldn’t experience pain was 4/10 points lower than the other group who were told it would hurt, and a bit over 2 points lower the second time (on a 0 – 10 numeric rating scale). That’s a thumping great amount of pain reduction! Add to this, these participants also were less afraid of their pain than the other group.

BUT, and this is important, participants in the “it’s not going to hurt” group reported less trust in the experimenter (who would have thought, huh?!). So beware: if you tell someone “oh this won’t hurt a bit” – they may experience less pain, but they’ll look at you sideways and be a bit wary of you because you violated their trust.

Discussion

I haven’t described the second experiment because of space, but go ahead and read it. Essentially they added some more participants, varied the procedure a little to reduce the memory burden on participants, and added a “medium” underprediction element into the process. The results showed similar outcomes – lower ratings of pain in both the “you won’t feel a thing” and the “it’ll hurt but not much” experiments, and yet again, less trust in the experimenter suggesting that it wouldn’t hurt.

Lessons to learn?

Think carefully about inflating how much pain relief someone will experience, especially if you’re going to see that person again. While people might experience less pain, losing someone’s trust in a therapeutic setting is a serious problem. The authors point out that healthy volunteers in a lab setting, getting short-term pain, is not like a therapeutic setting where it’s probable that trust is well-established. We don’t know what effect violating trust in a longer-term relationship might have.

At the same time – it does strike me as intriguing that simply being told “it won’t hurt” can influence pain intensity rating. What’s going on? How can a communication stimulus influence an experience? How could a psychological input change the way we perceive a noxious stimulus? Perhaps the way forward might be to use neutral language or, more positively, suggest that the person can handle it? “Just a little sting and you’ll get through”

When living with pain is too hard


**If you’re a person living with pain, and this headline caught your attention because you’re feeling it’s just too hard to carry on – PLEASE take a moment to seek help. If you’re feeling you can’t because they might judge you, or try to stop you feeling this way, at the very least give yourself an hour before you take any action. If that feels too long, give yourself a minute. Get through that, and give yourself another minute. And so on – until you’ve give yourself some time to let this awful feeling ease up a little. You can always revisit your decision to wait. Speak to someone – anonymously if you need to. There are helplines in every country. Phone one. Please.**

Living with persistent pain can be really hard, and clinicians, family and the person with pain can be worried about suicidal thoughts and possible actions. There’s good reason to be concerned, too, as a recent study from the 2012 Canadian Community Health Survey shows.

Grocott, Sommer and El-Gabalawy (2021) used the data obtained from this Canadian Health Survey to explore the relationships between pain intensity and suicidality in people with arthritis, migraines and low back pain.

The first question is how many people in the overall population involved in this study had any of the three diagnostic groups – and, as expected and in line with many epidemiological studies, between 10.3% (migraines) and 18.1% (low back pain) indicated they had been diagnosed. The “usual” pain levels across all three groups were between 25.9 – 27.7% indicating their pain was “mild”, 52.5 – 54.5% said it was “moderate”, and 19.7 – 20.9% described it as “severe”. This does not surprise me one bit – moderate levels of pain intensity are really common, and, albeit acknolwedging the difficulty of rating pain intensity on a numeric scale and the complex relationship between pain intensity and interference with daily life, demonstrate just how necessary persistent pain services are as a health services priority.

The team then identified the rates of “lifetime” suicidality – these were measured using the following questions.

“you seriously thought about committing suicide or taking your own life” (i.e., suicide ideation; yes, no), “you made a plan for committing suicide” (i.e., suicide plans; yes, no), or “you attempted suicide or tried to take your own life” (i.e., suicide attempts; yes, no).

It’s important to note that this question asked about whether the person had ever, during their life, had these thoughts – not that they were currently present. Remember this as you interpret this study, because suicidal thoughts are relatively common but acting on those thoughts is less common.

The authors found that people who were usually in pain were more likely to have suicidal thoughts, plans or had made an attempt than those who had periods of time without pain (ie intermittent pain). The different rates were reasonably large, too – just in terms of ideation, between 18.7 – 34.0% of people who were usually in pain had suicidal thoughts as opposed to those with intermittent pain (10.5-16.6%), and this association was particularly strong for people with migraine. For people with low back pain, having pain all the time was associated with much greater odds of suicidal thoughts (1.79, 95% CI [1.19-2.68], p<.05).

Pain intensity was also a factor – lifetime suicidality prevalence increased as pain intensity increased, and this was relevant to all pain conditions measured, and especially amongst people with severe pain and migraines.

A good question to ask is whether the odds were the same for people with current mental illness as for those without – and using the magic of statistics, the authors found that this only held for some forms of pain. People with arthritis (note they didn’t identify the kind of arthritis people had) reported lower levels of suicidality even in the presence of mental ill health.

The authors point out that this is an interesting study in that yes, suicidality was higher in people with migraines, and similar to other studies, but their intriguing finding was that differences in the intensity of usual pain increased the odds, along with elevated odds if people reported higher levels of pain intensity.

Why did I choose to summarise this paper?

A few reasons: one is that as health professionals, we may not be aware of just how many people in our communities live with pain. It’s a lot – and this study only included specific diagnoses. Yet, at least in New Zealand, pain management services for people with pain are scarce.

Most people in New Zealand will maybe get referred to a physiotherapist, but it’s often difficult for people with persistent pain to raise their issues with pain with their health provider and for those providers to respond with empathy (Thompson, Dowell, Hilder, Macdonald, Stubbe & Alchin, 2021). This means that many people may not be seen by clinicians with confidence to help people with psychosocial aspects of their pain (eg Holopainen, Simpson, Piirainen, Karppinen, Schutze, O’Sullivan & Ken, 2020, Zangoni & Thompson, 2017) if they even indicate that this is a concern for them during the consultation.

Another reason is that many clinicians who work mainly in “physical” health may not know what to do if someone does disclose suicidal thoughts. It is confronting to hear someone say they don’t want to live any more – and knowing what to do next can feel highly risky. How does this fit within my scope of practice? What if I say something wrong and the person goes ahead and attempts suicide?

Note though, that this study didn’t look at current levels of suicidal thought – it’s lifetime prevalence. Perhaps people who have had occasion to think about killing themselves have a greater degree of vulnerability for persistent pain, particularly when pain is intense. We don’t know – but the authors speculate. Worth reading the paper in full to find out their thoughts.

My thoughts (briefly!) are:

  • Prepare ahead of time. We’ll all likely encounter a person who is really distressed, at the end of their tether, and indicates they’re thinking of harming themselves. Being prepared makes responding to this situation much easier.
  • Preparation should include writing a policy for your practice or your setting. It should include a list of people to contact in a psychiatric emergency (when a person indicates they’re ready to take action to harm themselves), as well as specific actions to take when talking to the person.
  • We’re not all psychologists and it’s not our job to be psychologists – all we’re asked to do in this kind of situation is be a human. What I mean by this is – listen, affirm that the person is feeling really bad and support them to access the help they need. This might mean calling the psychologist if you have one you work with regularly, or calling the person’s family doctor, or calling psychiatric emergency services.
  • Ensure you hand the person to someone who will take care of them. This means not letting them go off in their car without letting their family doctor know, even if they say they’re fine. For your own reassurance this is important.
  • Take care of yourself. Don’t just go on to see the next person waiting for you. Take some time to process what’s happened, what you did, and debrief with someone you trust. It doesn’t need to be a trauma counsellor – it’s just as useful to talk to your colleagues who know you and the kind of work you do. Go have a cup of coffee, go for a walk, give yourself space to recognise that you just helped someone who was really distressed. That’s an important job.
  • Don’t ignore the person and pretend they didn’t just say that. Affirm that they’re feeling rotten. Don’t trivialise it and suggest they should just harden up, or it’s not really that bad, or that they’re at fault for feeling this way. Just be gentle and human, and recognise the privilege you have – this person trusts you enough to say how they’re really feeling. It’s an honour. So if you can’t think of anything to say, just sit with them and bear witness to their distress. Hand them a tissue. Be there for them.

Oh, and in that paper, while 18.7 – 34.0% had suicidal thoughts over their lifetime, 7.2–14.5% had made actual plans, while 6.6–14.7% had made attempts. Don’t trivialise suicidal thoughts, but at the same time, don’t freak out that the person is going to kill themselves – just take action to support them, and in most cases, the thoughts will fade as the person gains hope.

Why I don’t trust my clinical reasoning: and why this matters


“See someone experienced” I hear people with pain say. “They’ll know what’s wrong with you.”

Well, based on the research I’ve read, I wouldn’t be so sure. In fact, I’m certain my own clinical reasoning is biased, prone to errors that I don’t notice, and influenced by factors that most clinicians would be horrified to think they, too, were influenced by.

Let me give you a few to ponder:

I’m interested in women and pain – and there’s a lot of evidence showing that women’s pain doesn’t get the same kind of diagnostic and management attention as men. Now part of this is due to the inherent bias in research where experimental studies often rely on male rats, mice and undergraduates because they don’t have those pesky hormonal fluctuations each month. Even volunteering to take part in a pain study has been found to be biased – people who volunteer have been shown to be more risk-taking and more extraverted (Skinner, 1982) – though to be fair this is an old study!

But contextual factors such as gender, distress and even the supposed diagnosis do influence judgements about pain intensity (Bernardes & Lima, 2011) including potentially life-threatening chest pain (Keogh, Hamid, Hamid & Ellery, 2004). Gender bias has been identified in a large literature review of gender bias in healthcare and gendered norms towards people with chronic pain (Samulowitz, Gremyr, Eriksson & Hensing, 2018).

And if you have the misfortune to be judged to have low trustworthiness and you’re a woman, you’re more likely to be thought to have less pain and to be exaggerating your pain (Schafer, Prkachin, Kaseweter & Williams, 2016). Beware if you’re overweight and a woman because you’ll be likely judged as having less intense pain, the pain will be judged as less interfering, more exaggerated and less related to “medical” factors – women’s pain in particular is likely to be judged as “psychological” and given psychological therapy rather than other treatments (Miller, Allison, Trost, De Ruddere, Wheelis, Goubert & Hirsch, 2018).

The weird thing is that the clinicians involved in these studies were oblivious to their bias. And let’s not even go there with people of colour or so-called “minority” groups such as LGBTQI.

So as clinicians our initial impressions of a person can lead us astray – and I haven’t even started with the contribution experience has on clinical reasoning. Let me go there then!

Something that cognitive psychologists have explored for some years now, is the type of thinking that we draw on for clinical reasoning. System one is “fast reasoning” – where we rapidly, instinctively and emotionally make decisions on the fly. Kahneman (1982) first described these two processes and noted that fast thinking gets better with rehearsal and are helpful especially for skilled clinicians needing to make decisions in pressured contexts, and draw on “pattern recognition” – or to be precise, draw on deviation from a recognised pattern (Preisz, 2019). System two is “slow reasoning” where decisions are made in a considered way, are not influenced by emotional state, and can be thought of as “rational.” Slow thinking is most useful where the situation is complex, where decisions need to weigh multiple pieces of information, where the situation might be novel, or where, for persistent pain in particular, there are multiple disease processes occurring.

OK, so we should choose system two, right? Not so fast! System one is hard to switch from – it’s what underpins “intuition” or “hunches” – and it gets more entrenched the more experienced we are. According to Preisz (2019), system one “seeks to form a coherent, plausible story by relying on association, memories, pattern matching and assumption.”

Why is system one thinking not so great? Well, we’re human. We’re human in the way we respond to any reasoning situation – we anchor on the first and most “plausible” ideas, and these might be unrelated to the actual presentation we see. For example, if we’ve been reading a journal article on a new treatment and its indications, it’s amazing how many people will present with those exact same indications in the next week! This is availability bias or anchoring bias. We’re also inclined to believe our own patients and judgements are different from “those people” – especially “those people” who might respond best to clinical guidelines. This means that even in the face of clear-cut research showing the lack of effects of knee arthroscopy (Brignardello-Petersen, Guyatt, Buchbinder, Poolman et al, 2017) an orthopaedic surgeon I know argued that “we choose our patients very carefully” – essentially arguing that his patients are different, and this approach is the best one.

If experienced clinicians find it hard to “unstick” from old practice, or move quickly to “intuitive” reasoning (even if it’s called “pattern recognition”), and if we all find it hard to recognise when we’re biased, or even that we are biased, what on earth should we do? All us old hands should retire maybe? All follow algorithms and not use “clinical judgement”? Take the “human” out of clinical management and use AI?

Some of these things might work. There is evidence that algorithms and AI can offer effective and (perhaps) less biased diagnosis and management than our unaided human brain (Kadhim, 2018) but there are also studies showing that direct comparisons between decision aids and clinical judgement are rarely made, and those that have been carried out don’t show superior results (Schriger, Elder, & Cooper, 2017). But watch this space: AI is a rapidly developing area and I predict greater use of this over time.

The risk with decision aids is – garbage in, garbage out. If we look at existing research we can see that male, pale and potentially stale dominates: this doesn’t bode well for people of colour, for women, for the unique and idiosyncratic combination of diseases a person can have, or for untangling the impact of disease on the person – in other words, disability and illness.

So, to summarise. We are all biased, and it’s best to acknowledge this to ourselves upfront and personal. We can then turn to strategies that may reduce the biases. For me, the one I turn to most often is a case formulation, using information gathered from a semi-structured interview and a standard set of questionnaires. These have been developed a priori so my biases in information gathering are limited. By taking time to follow a case formulation, my thinking is slowed to that more deliberative system two. At least some of the biases I know I’m prone to are mitigated.

And yet, I know I am biased. That’s why I use a supervision relationship to help me identify those biases, to be challenged and to reflect.

Knowledge gaps for working together


Whenever we work with someone living with pain, we form a team. A team, by definition, is “a distinguishable set of two or more people who interact dynamically, interdependently, and adaptively towards a common and valued goal/objective/mission” (Salas et al., 1992). So while many clinicians work outside an interprofessional team, they are always working in a team consisting of at least the person with pain, and themselves.

There’s a good deal of research on teamwork, and a heap of references in pain management literature on the benefits and, indeed, the need, to work in a team for best outcomes (both in terms of effects for the person and in terms of cost-effectiveness). Gilliam and colleagues (2018) demonstrate that long-term outcomes are retained by participants attending an interdisciplinary pain rehabilitation programme, while Guildford and colleaguees (2018) also showed reductions in analgesic use during an interdisciplinary pain management programme. It’s not new news folks!

Teamwork is well-investigated in health, particularly interprofessional/interdisciplinary teamwork. Much of this research, however, is focused on nursing and medicine interactions, with rather less attention paid to allied health and nursing/medicine teamwork. This matters because while nursing and medicine are moving away from the old medical model, the professions probably represent the two most similar in terms of clinical models. And this matters because one thing that’s found to be important for good teamwork in health is having a shared mental model (for example – from operation room – Wilson, 2019).

All good so far – nothing new here, move along, right?

Hold it right there, folks.

You see, when we work together in a team, particularly for people with persistent pain, we often generate a heap of new information about the person we hope to help. In New Zealand, the person will have completed the ePPOC set of questionnaires, then there will probably have been some physical performance testing, maybe some basic ROM, and muscle testing, perhaps some daily life functioning tasks, certainly some more psychological questionnaires, if the person sees a medical practitioner, there will be the obligatory bloods, urine, perhaps imaging – you know what I mean! A heap of information that each clinician deems necessary and I haven’t yet gone into each clinician’s desire to “hear the story from the beginning again!”

What’s lacking in our research on teamwork in persistent pain is discussion about how we assemble this information so that we move from a multidisciplinary team – Multidisciplinary teams involve people from different health disciplines working alongside one another while using clinical models drawn from their own professional discipline (Körner, 2010) – to an interprofessional/interdisciplinary team – Interdisciplinary teams also involve people from different health disciplines working alongside one another but meet regularly to collaborate on treatment goals and priorities (Ruan & Kaye, 2016). There is limited hierarchy and considerable communication, cooperation and often overlap between team members (Körner, 2010).

Not only a lack of a shared mental model (because we all think our model is The Best), we also lack an understanding of team processes. How do we develop an effective way to communicate, to cooperate, to deal with conflict in an open and creative way, to coordinate our work so things happen at the right time, to be coached so that the team-as-a-whole moves in the same direction and new people coming to the team feel part of the culture? Not forgetting that teams work in an ever-changing context, and team membership changes over time, while the overall team culture is something that emerges from a team collective (Salas, et al., 2015).

Are pain rehabilitation teams different from teams working in older person’s health, or palliative care, or as part of a primary health team?

I suspect so, but I can’t find good research detailing how our pain teams are different. It’s like a black box of mystery (a bit like interprofessional pain management programmes – one murky black box out of which a person pops!)

I’m left with this feeling that because teams in pain management and rehabilitation have become scarce in most part of the US, and that this is where all the research funding lives, there’s not very much that we actually know. We don’t know who holds the positions of power – is it the medical practitioner? the psychologist? the physiotherapist? the occupational therapist? Who makes the call as to when it’s time to work with the person to move from pain reduction to living well alongside pain? Are the team members actually using a common model or are they really working in parallel? And how can a team be maintained over time – I’ve had the privilege of working in a very close-knit and effective team for some years, but I’ve seen that team become smaller, fragmented, more multidisciplinary than interprofessional, with limited attention to processes of induction, developing effective conflict management, and really becoming weakened.

There is one conclusion I can draw from the mountains of material I’ve been learning and it’s this: it’s impossible to put a bunch of clinicians together and call them a team without putting effort in to develop those processes I’ve listed above. And when was the last time you attended a CPD session on “how to work in a team?”
