Life seems but a succession of busy nothings – Jane Austin


We hold some very contradictory opinions about being busy. On the one hand, Socrates is reported to have said “Beware the barrenness of a busy life”, and on the other Dale Carnegie is quoted as saying “Inaction breeds doubt and fear. Action breeds confidence and courage. If you want to conquer fear, do not sit home and think about it. Go out and get busy.”

Pacing, one of the cornerstones of “traditional” pain management, is intended to moderate both under-activity (avoidance) and over-activity so that important things can get done without running out of puff – or having an enormous flare-up of pain with subsequent crash into a jellied lump. Yet people who cope well with pain, and ourselves if we’re honest, are often guilty of doing more when we are highly  motivated to do something (or want to achieve a specific goal), and doing less afterwards so we can recuperate.

What is an optimal level of activity for a person living with chronic pain and why might this be important?

I’ll address the second question first. Fatigue is experienced by many people living with chronic pain. Fatigue is a term “used to describe a period of extreme tiredness, as a result of emotional strain, physical exertion, boredom or a general lack of rest and sleep” (Psychology dictionary) People living with chronic pain often develop a sense of fatigue as part of their pain, and some authors believe that not only is it because of disruption to the delta sleep phase (the deepest sleep we achieve), but also because some brain activity continues all the time as the neuromatrix processes potential threat from the painful parts of the body. This activity may result in changes to brain structure, although brain structures may actually cause some of this effect (Baliki, Geha, Apkarian & Chialvo, 2008; Wiech, Ploner & Tracey, 2008). The practical impact of experiencing fatigue is to reduce cognitive efficiency: it takes longer to solve problems, and even boring tasks can feel very difficult.

Some interesting facts: the effect of fatigue on performance differs depending on an individual’s beliefs about fatigue – there is a thing called “fatigue catastrophising” which, like pain catastrophising, means individuals unduly and negatively assess the effect of fatigue on their ability to do things. Being fatigued influences the ability to switch tasks from one task to another, fatigue reduces the ability to ‘change tack’. Interestingly, being bored increases the likelihood of experiencing fatigue. There is an optimal level of stimulation in which we operate. Stress, while initially increasing alertness, over time results in increased fatigue.

So in terms of the importance of identifying and developing an optimal level of activity, it seems that for people living with chronic pain, there might be a need to carefully work out just what level of activity is sufficient to avoid boredom but not so much as to stimulate unhealthy levels of fatigue.

And now, what is an optimal level of activity for a person living with chronic pain?

This question is a much more difficult question to answer, not only because “optimal” will depend a great deal on an individual’s satisfaction with his or her activity level, but also because it’s difficult to measure, definitions about activity level are unclear, and because there are many assumptions about activity levels that have been retained since the early operant conditioning model of pain was proposed by Fordyce. In this model, avoidance develops by reducing activity levels as a way to reduce pain (or prevent it from increasing), while over-activity is thought to occur when activity increases pain resulting in avoidance. Some research suggests that over-activity is an ongoing habit used by individuals who have always tended to be those that work long hours and remain highly engaged in activities they value.

There has been a lot of interest in the notion of over-activity, in part because of the recent interest in “pacing”, but also because people who “over-do” exhibit some features inconsistent with the old avoidance model. For some reason people who over-do engage in activity that will increase their pain – and yet they continue doing so, despite the need to “recover” or do less on the days following their high activity days. Something is overriding the (expected or usual) sense of concern about experiencing pain at the time of their over-activity.

A study by Andrews, Strong and Meredith (in press) looks at activity patterns and particularly over-activity and avoidance patterns and has been able to validate the construct of “over-activity” as a pattern of activity that increases pain – but inconsistent findings relating to avoidance and over-activity. While pain is known to increase, the effect of this on future activity levels is not yet known.

What I wonder is whether these patterns relate to contextual aspects of activity carried out by people living lives. We all know that we push ourselves some days and chill out a little on others. We know that sometimes we’ll do things that will be either fatiguing or actually generate pain (like when you need to move house, dig the garden in spring, do a fun run, have a Christmas dinner at our place), and for most of us this is something we accommodate by being a little less busy for a couple of days afterwards. If we take actigraph recordings over a week or two (Jawbone anyone?), I’m sure it will also show a pattern of high activity and then lower activity, so that over time the activity levels probably flatten out around a mean level of activity. When we do something we value very much, the perceived sense of effort (fatigue) may be lower – we feel energised and enthused although we are tired. When we do something we don’t value (for me it has to be vacuuming!), it feels more tiring and time goes very slowly.

I wonder if people living with pain need additional time to “recover” because of both increased pain, and also the feeling of fatigue. And whether perhaps we need to also study what it is about the tasks being undertaken that is valued rather than simply the task activity level. Busyness may depend on the value of what is being done.

Those who expect moments of change to be comfortable and free of conflict have not learned their history ~ Joan Wallach Scott


I’ve been touring North America – Chicago, Toronto, Edmonton and Vancouver. As I’ve toured I’ve been listening to the stories of change and insight as different professions review their contributions to effective pain treatment. Some things change, some things stay the same – but as the quote above indicates, change isn’t comfortable nor free of conflict.

What have I found in my travels?

There’s a great deal to be proud of in our approaches to helping people who live with pain. Allied health practitioners of various backgrounds have adopted and adapted to the discoveries about how people experience and deal with their experience of pain. There’s been enormous change in our views of pain as neither a form of mental illness (or malingering, or imagination, or even simply weakness of spirit), nor a lifelong static state. Allied health practitioners of every kind know that they can contribute to helping people make sense of their pain, perhaps change their experience and reduce the distress and disability that living with pain can bring.

Disturbingly, though, I heard the exact same issues as those I face in New Zealand, when it comes to unrest and disquiet about competence, scope, and funding for effective treatments.

Disquiet because some of the different professions lay claim to certain areas of practice as “theirs”. Disquiet because there are attempts to limit access to learning about aspects of pain that are integral to the experience and management of pain. Concerns that some clinicians might be overstepping their scope when they begin to develop skills in, most notably, psychosocial aspects of our experience of pain. And disproportionate funding given to short-term (primarily) biomedical interventions without a consistent or even logical argument for similar funding levels to be applied to allied health approaches. Or worse – funding given to those working in a single-discipline approach, and loss of funding (or funding not even considered for) approaches where teamwork is a critical part of the treatment.

As a somewhat renegade occupational therapist with a MSc in psychology, PhD in health sciences, and great interest in psychosocial aspects of pain, I know that I don’t sit especially comfortably in one little box. And it was SO refreshing to find that I’m not alone in this. As allied health professionals develop knowledge and skills in a biopsychosocial and neurobiologically sophisticated model of pain, it becomes increasingly difficult to distinguish between the practice of good occupational therapists, physiotherapists, massage therapists, psychologists, nurses and social workers when working with people who live with pain.

Our aims are the same: we want to help people live good lives despite experiencing pain. Some of the ways we ALL do this are to help people reconceptualise pain as something that is not fixed but can be influenced by reducing the threat value of the experience within the context of what we view as important.

We ALL draw on learning theories, influencing beliefs and attitudes, consider contingencies and work at reducing the relationship between experiencing something inherently unpleasant and avoiding that experience.

We ALL help people set goals, work hard to achieve them, use movement and activity to help pursue what is valued and deal effectively with what gets in the way of this.

We ALL use motivational approaches, we ALL consider personal values and choices, we ALL want the people we work with to have the freedom to choose personally-valued goals and outcomes.

We ALL draw freely on the published scientific literature across all the branches of pain research – biological, psychological, and to a lesser extent, sociological. (I’d love to see far more emphasis on the social as I’m sure regular readers know!).

It confuses and perplexes me that each one of our professional groups has, at times, criticised other professions for failing to address or consider the aspects of pain experience that our particular group sees as critical. But what really perplexes me is that once another profession begins to take up the challenge of adopting and integrating learning from “outside” their original knowledge base, some people turn right around and begin to criticise that group for “working out of scope”. It does not make sense.

A discussion that I think needs to begin is to consider the merit of a specialist “certification” if you like, for those people who have taken time to learn about pain in-depth, and who no longer fit as comfortably within their original profession as they once did. As I saw so often in my travels, when we get beyond the simplistic level of learning about pain as a biopsychosocial experience we begin to recognise that the way we work with people changes over time to become so much more similar than dissimilar that our professional disciplinary approaches seem to fade away.

I know that in the years since my original training and graduation as an occupational therapist (waaaay back in 1983) I’ve done so much more learning and development that what I do now is so very different from what I did then. I’m still essentially interested in helping people do what is important in their lives. Doing, or occupation, is integral to my practice. The ways I help people achieve this (thus reducing distress and disability) has changed but my “domain of concern” (old-fashioned language for “what I’m interested in”) is still occupation, or the things people want and need to do in daily life.

The obstacles to participating in occupations might be addressed in slightly different ways, but I draw on the same fields of knowledge that I drew on in 1983. Just as I learned then that biomechanical, kinesiological, anatomical, biological, psychological, social, anthropological – and the rest – ways of understanding human behaviour informed the way I work with people, I STILL draw on those same fields of knowledge. The first three fields might have less influence now than I thought they did when I first started working in pain management, but they all contribute.

So here’s the thing: if there is so much our different professions have in common with one another, is it time for allied health professionals to work in a united way to demonstrate just how significant our contribution is to the health and wellbeing of people living with pain? Is it time to trust one another just a little more and stop the infighting as to who is working “in” or “out” of scope? Isn’t it time we looked to the people we work with and for, and focused a little more on sharing our expertise with one another? Shouldn’t we trust that if we’re interested in what works well for the people we want to help, we’ll develop effective knowledge and skills rather than thinking, like Gollum “It’s mine! It’s my preciousssssss!”

I truly thing we can do a much more effective job if we remember that while we let go of some things that we think of as “ours” we might have made just a little room to add some new skills to our own repertoire? And perhaps that change might happen more smoothly if we were more accepting of the need to let go some control and trust a little more.

When medication side effects get in the way of living life


There are very few people living with chronic pain who gleefully swallow a handful of pills and skip happily off for the day feeling chipper and bright as a button. For the most part, people living with chronic pain don’t seem to enjoy the need to take medications – I’ve heard some say they’re worried about “not being able to tell whether I’m doing damage” when they can’t feel their pain, others say they don’t think medications are very helpful, while still others complain about rattling when they walk. But by far the biggest complaint is the medications for chronic pain have unpleasant side effects – side effects so bad that for some people, it’s just not worth taking the pills at all.

Surprisingly, although there are many studies looking at the side effects of medications, and why they occur, the effect of side effects on doing everyday activities has seldom been examined. Thankfully a group of researchers from Harvard and Johns Hopkins have taken on this task, and we now have some information about just how much side effects can get in the way of life.

What side effects do people experience?

Nausea, dizziness, headaches, constipation, weakness, cognitive fogginess, excessive sleepiness, skin itchiness and rashes, muscle twitching – you get the drift!

Why do they happen?

Many medications for pain, and particularly medications for chronic pain, exert their influence on the central nervous system – where the receptors for neurochemicals important in modulating our experience of pain are found. It would be fabulous if there were some separate receptors that only dealt with “unhelpful” pain that could be targeted, but because pain is an adaptive response designed to protect us – and because in evolutionary terms experiencing pain is crucial to our survival and has been present from early on in our evolutionary development – receptors targeted by many pain medications are found throughout the body. And particularly in the brain – hence the fogginess, sleepiness, and headaches.

What does this mean?

When prescribing medications for chronic pain, clinicians and their patients ultimately go through a process of empirical study. What this means is that because we don’t know which type of medication is most likely to help an individual, each one needs to be tried out. And the trial and error process involves establishing the balance between helpful effects – yes, pain reduction, perhaps some help with sleep – and unhelpful effects – those side effects. The process of deciding which particular combination of medications to take is absolutely personal – only the person with pain can possibly determine whether they find the balance of helpful vs unhelpful effects tolerable.

What about this study?

In this study, Martel, Finan, Dolman and colleagues (2015) sampled a group of 111 people living with chronic musculoskeletal pain. The participants were asked to report once a month, for six months, on their medication use, side effects, and pain and activity levels.  Interestingly, the group selected had to have been prescribed opioids because the larger study of which this one was a small part, was designed to establish ways to improve adherence to medication taking. In addition, this group of people were considered to be at risk of prescription opioid misuse based on an assessment for this problem, but those with a current or past substance abuse problem within the past 12 months. What this means is that while the study has some interesting findings, they will not be representative of all people living with chronic pain, and results need to be interpreted in this light.

OK, OK, I’ll get on with it!

The findings

There were no differences between men and women in terms of pain intensity, mood or pain-related activity interference but women were more likely to describe side effects due to medication. Reports of side effects were no different between those taking opioid medications as well as other pain medications such as antidepressants, anticonvulsants or NSAIDs.

Now for some expected findings: people reporting greater pain-related interference were less likely to be employed, while changes in pain intensity were related to pain-related interference, and similarly, changes in mood were also associated with greater pain related interference.

After some statistical magic (multilevel modeling is horrendously complex!), these researchers examined the unique contribution of medication side effects on pain-related activity interference. What they found was that side effects contributed a unique amount to interference even after controlling for gender, pain intensity and negative mood, and even taking into account individual differences between people.

Now this is important. Medications are prescribed for pain for two reasons: to reduce pain (obviously) and it’s assumed that because pain is then lower, pain-related interference will also be lower. In other words, people will feel less pain and do more things they want to do. What this study suggests is that the burden of side effects from medications can actually ADD to the burden of disability experienced by people living with pain. Now, one way to deal with this is to reduce the number of medications a person takes. That would take care of the side effect burden – but it would also increase the pain. Both distress and disability may then increase. An alternative is to treat the side effects with something else – a bit like taking something to stop constipation when being prescribed opioids. But that in itself can create problems – because, as many people I’ve talked to mention, they really don’t want to rattle like a pill bottle from all the medications they have to swallow.

I think there are two more alternatives. One is to look at the timing of medication taking. I’ve seen many people prescribed gabapentin three times a day – but gabapentin is sedating, and people complain of the effects on driving and on concentrating at work. An alternative, and one that I’ve seen carried out very successfully for years at Burwood Pain Management Centre in Christchurch, NZ, is prescribing the same dose of gabapentin, but taking it once a day at night. A good night’s sleep is had, and the hangover effect during the day is minimised. But this requires a change in how the doctor prescribes – and some confidence to fiddle about with the timing of the dose. It also suggests that the person living with pain, his or her doctor and probably the pharmacist need to work together to develop a plan that maximises the effectiveness of medication administration.

The second is to look at reducing reliance on medication as the primary form of coping strategy for chronic pain. This solution is a vexed one. Many people living with chronic pain are afraid to reduce their use of medication. Many doctors are unaware of alternative ways of coping even though it’s evident that as many as three people in four will not obtain any benefit from medication.  Worse still, many communities have few treatment providers available to help people develop nonpharmacological ways of living well with pain. I think that’s a tragedy and I think it’s time that changed.

“Failed back surgery” syndrome – who or what failed?


It’s a term I thought had died a natural death. Failed back surgery syndrome. I used to hear it in the late 1980’s when people with low back pain often had five or six surgeries to try to “fix” whatever wasn’t working in the back. I hadn’t heard it for a while and I really thought it had gone the way it should have – into that great rubbish bin diagnosis pile in the sky, along with “somatisation” and “functional pain” and trigger points. But, to my astonishment, there it is, now a separate MeSH title when you search through Ovid or Medline.

The question I always ask is “Who or what has failed?”

Is it the patient who dares to carry on saying that they have pain, sometimes even more pain than before surgery?

Is it the surgeon for choosing the wrong surgery, or perhaps for doing surgery at all?

Is it the nervous system, already sensitised, now subject to more sensitisation through the planned trauma of the surgical scalpel?

Is it the system for funding surgery?

In a paper written by Shapiro (2015), the rate of “failed back surgery syndrome” is reported as being between 10 – 40%. It seems to increase when the surgery is complex, and it hasn’t improved despite developing less invasive surgical techniques.  Shapiro goes so far as to define FBSS as  “a multidimensional chronic pain syndrome that has significant myofascial and psychosocial components that are directly related to the high incidence of lumbar surgeries in the United States.” Sorry to say, but it’s not just present in the US.

These are the psychosocial risk factors, as identified by Chan and Peng :

  • significant levels of depression,
  • anxiety,
  • poor coping,
  • somatisation
  • hypochondriasis

To be honest, I think these indications would be risk factors for ANY surgery (and probably ANY invasive procedure, including dry needling). But there’s more than this – preoperative risks such as having had prior surgery (spinal instability seems to become worse with repeated revisions); surgery carried out when imaging results suggest there may be good reason, but there is no corresponding clinical correlation; nonsurgical cases of radiculopathy and neuropathy (eg diabetes, viruses, inflammation, vascular disease). And intra-operative risks such as difficult radiographic imaging, inadequate decompression – this paper uses the term “pain generator” for the potential source of nociception, but you and I know that pain only occurs as an output of the brain within a biopsychosocial system; lots of other surgical issues including bleeding, fragments of tissue, “battered root syndrome” (!) where the nerve root is damaged during discectomy; and finally, there are a load of post-operative issues as well – such as haematoma, pseudoarthritis, fibrosis, irritation of the nerve roots, spinal instability, loss of disc height and the list goes on.

Shapiro suggests that some types of ongoing pain after surgery are misdiagnosed myofascial pain, stirring up or producing trigger points. He does add that central sensitisation in the dorsal horn could also play a part, expanding receptive fields in the spinal cord and amplifying “perception” (once again, think of this as amplifying nociceptive input reaching the brain). He also favours the notion of motor control problems following surgery, again compounding the problems that occur with movement after surgery and feeding back into the ongoing pain experienced by the individual.

Shapiro also goes on to suggest various ways the problems could be ameliorated, primarily through careful imaging and then possible surgical management.  The overall management, however, he argues should be pharmacological, “with the goal of increasing physical activity and community involvement”.  Interestingly, Shapiro says “FBSS patients are often pushed aside and told that their surgeons have little to offer them after their surgeries were unsuccessful. These patients are generally managed by community-based physicians, including primary care physicians, anesthesiologists, physiatrists, and neurologists.”  He goes on to say “Treatment of FBSS demands recognition that it is a chronic pain syndrome. One reason that FBSS is a difficult-to-treat syndrome and a public health problem is that the antecedent back pain did not respond to intervention and was often augmented with additional pain complaints caused by the surgery. The psychosocial burden for individuals is huge, especially if there is job loss or loss of function physically. Many of the immediate postoperative pharmacologic strategies complicate the situation further by altering the patient sensorium, mood, affect, and even libido. Opioid-induced hyperalgesia is probably under-recognized and under-reported.”

What does this mean to me?

It must be terribly distressing to be offered a treatment for low back pain and leg pain that is both invasive and expensive – only to find that it hasn’t helped one bit. And even more distressing to then be advised that “there is nothing more I can do, it’s a risk of having surgery”. Worse, then to be advised that the options for managing this pain are quite limited – and for many people, means repeated surgery, perhaps even to the point of having a spinal cord stimulator implanted (with all the known complications of this kind of intervention). Shapiro describes people being offered facet joint radiofrequency neurotomy, but even he acknowledges that “it does not offer a permanent fix to facet-mediated pain, which should raise concern with regard to overutilisation”.

What astonishes me, but probably shouldn’t, is that interdisciplinary pain management approaches continue to be seen as costly, yet there is ample research showing these programmes achieve clinical and cost-effective improvements in patient function.  I’ll let you draw your own conclusions from the following paragraph snipped from Shapiro’s paper:

The cost for this individually tailored 20-day outpatient program, including physical therapy, occupational therapy, and psychological support, is approximately $15,000 (Pain SolutionsNetwork, personal communication, 2013). This is similar to the cost for a single-level laminectomy not requiring a hospital stay and is substantially less costly than the direct costs for lumbar fusion when hospital, hardware, surgeon, and anesthesia costs are added up. [and I’d go even further to add that the 30% risk of a poor outcome is even more expensive…]

I think the health system has failed the people who undergo surgery for low back pain. With a failure rate quoted by Shapiro as approximately 30%, and an increase in epidural injections and facet joint injections of over 250% without any similar improvement in health status, something is going wrong. Very wrong.

Allied health professionals can and do provide cost-effective interdisciplinary pain management for people living with so-called “failed” back surgery syndrome. I think it’s time for allied health professionals to begin agitating, and perhaps even advertising direct to people who have pain – we can help. Our treatments don’t have the risks of invasive procedures. We are focused on helping you DO despite your pain. And what we do can hardly make your pain worse – unlike some of the very sad stories I’ve read.

Central sensitisation – can a questionnaire help find out who is, and who isn’t?


My orthopaedic colleagues have been asking for a way to identify which surgical candidate is unlikely to have a good outcome after major joint surgery. They know that between 10 – 50% of people undergoing surgery will have chronic pain.  5 – 10% of those people experiencing pain that’s rated >5/10 on a numeric rating scale where 0 = no pain, and 10 = most severe pain you can imagine ( Kehlet, Jensen, & Woolf, 2006). The people with severe pain are the kind of people who hear “well the surgery I did went well…” and can be left wondering why they ever decided to go ahead with their surgery.

Two main factors seem to be important in postsurgical chronic pain: the presence of central sensitisation (usually indicated by reporting chronic pain in at least two other areas of the body) and catastrophising. I’ve discussed catastrophising a great deal here and here .

What I haven’t talked about is central sensitisation. Now, the idea that people can experience chronic pain associated with changes in the way the nervous system responds to stimuli isn’t new, but the neurobiology of it is still slowly being unravelled.  I’m not going to get into definitions or whether having changes in the nervous system equates with “chronic pain” (because pain is an experience and the neurobiology is just the scaffolding that seems present, the two are not equivalent). I want to talk about the measurement of this “sensitisation” and whether a pen and paper tool might be one way of screening people who are at greatest risk of developing problems if they proceed with surgery.

First of all, what symptoms come under this broad heading of “response to an abnormally sensitised nervous system”? Well, Yunus (2007) proposed that because there are similarities between several so-called “medically unexplained symptoms” such as fibromyalgia, chronic fatigue, irritable bowel disorder and so on, perhaps there is a common aetiology for them. Based on evidence that central sensitisation involves enhanced processing of many sensory experiences, Yunus proposed the term “central sensitivity syndrome” – basically a disorder of the nociceptive system. Obviously it’s pretty complicated, but various researchers have proposed that “dysregulation in both ascending and descending central nervous system pathways as a result of physical trauma and sustained pain impulses, and the chronic release of pro-inflammatory cytokines by the immune system, as a result of physical trauma or viral infection… including a dysfunction of the stress system, including the hypothalamic–pituitary–adrenal axis (Mayer, Neblett, Cohen, Howard, Choi et al, 2012, p. 277)”. (what are “pain impulses”?!)

By proposing this mechanism, various researchers have been able to pull together a number of symptoms that people experience, and their premise is that the more symptoms individuals endorse, the more likely it is that they have an underlying central sensitisation disorder.

The authors completed a literature review to identify symptoms and comorbidities associated with fibromyalgia and the other disorders they believe indicate a sensitised central nervous system. they then develop a self-report instrument and asked people with these problems to complete it, and compared their results with a group of people who wouldn’t usually be thought to have any sensitisation problems (students and staff at a University – we could argue this, but let’s not!).

What they found, after much statistical analysis, is a four factor measure:

Factor 1 – Physical Symptoms (30.9%)
Factor 2 – Emotional Distress (7.2%)
Factor 3 – Headache/Jaw Symptoms (10.1%)
Factor 4 – Urological Symptoms (5.2%)

Test-retest reliability was established, and because the questionnaire could discriminate between those who reported widespread pain (aka fibromyalgia) and those who had no pain, it’s thought to have discriminant validity as well. (BTW a copy of this measure is included in the appendix of the Mayer, Neblett, Cohen, Howard, Choi, Williams et al (2012) paper – go get it!)

The researchers then went on to look at some norms for the measure and found that amongst people with chronic pain, referred to an outpatient multidisciplinary pain centre, those with more diagnosed “central sensitisation syndromes” scored more highly on this measure, and that a score of 40 on the measure was able to discriminate between those who didn’t have sensitisation and those who did (Neblett, Cohen, Choi, Hartzell, Williams, Mayer & Gatchel, 2013).

Well and good. What does it actually mean?

This is where I think this measure can come unstuck. I like the idea of people being asked about their pain and associated symptoms. We often don’t have time in a clinical interview to ask about the enormous range of symptoms people experience, so being able to get people to fill out a pen and paper measure to take stock of the different things people know about themselves is a good thing.

What this measure doesn’t yet do is indicate whether there is any underlying common causal link between these experiences. It’s tautological to list the symptoms people might experience with central sensitisation based on the literature, then ask them to indicate which ones they experience and then conclude “oh yes! this means they have central sensitisation!” All it means is that these people report similar symptoms.

What needs to happen, and is now beginning to occur, are studies examining central nervous system processing and the scores individuals obtain on this measure. That, and establishing whether, by completing this questionnaire, it is possible to predict who is more or less likely to develop things like post-surgical chronic pain. Now that would be a really good measure, and very likely to be used by my orthopaedic colleagues.

In the meantime, whatever this measure indicates, it seems to be able to differentiate between people who are more likely to report “medically unexplained symptoms” and people who don’t. This might be useful as we begin to look at targeting treatment to suit different types of persistent pain. At this point in time, though, I think this measure is more useful in research than clinical practice.

My North American Tour!! #Bronnie2015


It’s fast coming up – my wonderful North American tour!! Thanks to some amazing friends who have organised the details, I’m going to be in North America from the end of May to mid-June at the following places:

11 June – one day workshop on graded exposure!
13/14 June
What am I doing?
This is a two-day workshop on integrating biopsychosocial factors into clinical assessment, clinical reasoning and treatment planning. It’s about taking pain management from the clinic into the real world. It’s a time to learn more about the practical aspects of integrating these messy concepts – without breaching your scope of practice!
By the end of the two days you’ll have some tools you can use on Monday, gained confidence and had fun.
Come and join me and the fabulous team who have done all the arranging for these workshops!

What does using a biopsychosocial framework mean in practice?


A good friend of mine told me that during her training (as a physiotherapist), psychosocial factors were “what you blame when your treatment doesn’t work”. It’s something I’ve heard more than once. I’ve also been asked many times “…but are you sure you’re not doing something outside your scope of practice?” when I talk about using cognitive behavioural principles and ACT (Acceptance and Commitment Therapy) and other psychological strategies. And some of you might have seen earlier posts of mine where I ask “How social is your biopsychosocial model?”

Today’s medical students are trained in using a biopsychosocial framework in their undergraduate years. They leave medical school, begin their hospital and advanced training, and I guess I wouldn’t be alone in asking “what happened to the psychosocial?” when we see them working.

So today’s post is a bit of a reflection and a musing on what I think using a BPS approach might mean in pain practice.

BPS is, I think, less of a “model” than a way of thinking. Thinking that is based on a systems approach – every factor affects and is affected by every other factor. In fact, Engel, the originator of this way of viewing human health, was strongly influenced by general systems theory which was developed by Ludwig von Bertalanffy, a biologist who lived between 1901 – 1972. General systems theory was a model describing processes thought to be common in many different fields of knowledge. General systems theory is based on these five beliefs:

(1)  There is a general tendency towards integration in the various sciences, natural and social.

(2)  Such integration seems to be centred in a general theory of systems.

(3)  Such theory may be an important means of aiming at exact theory in the nonphysical fields of science.

(4)  Developing unifying principles running ‘vertically’ through the universe of the individual sciences, this theory brings us nearer to the goal of the unity of science.

(5)  This can lead to a much-needed integration in scientific education.

Engel then applied this to a model of the influences on human health. At the time he wrote his seminal article (Engel, 1977), psychiatrists were being challenged by reductionism on the one hand, particularly around approaches to mental health – the distinction between “diseases” where biological causal factors are influential, such as neurological disorders, and “problems of living” such as alcoholism, where the relevance of biology was, at the time, hotly debated; and concern that psychiatrists might lose ground to nonmedical practitioners such as psychologists. It’s an argument that continues today: should, for example, nonspecific low back pain be the domain of medical practitioners or should physiotherapists, occupational therapists, psychologists and others pick up primary responsibility for its management? (For a very interesting discussion of socio-political debates about this, read Wilson, N., Pope, C., Roberts, L., & Crouch, R. (2014). Governing healthcare: Finding meaning in a clinical practice guideline for the management of non-specific low back pain. Social Science & Medicine, 102(0), 138-145. doi: http://dx.doi.org/10.1016/j.socscimed.2013.11.055)

Back to the story. The broad BPS “model” can’t be tested, and to some, was never intended to be a “scientific” model but rather a discussion tool. A way of shaping a dialogue between the person seeking help, and the clinician wanting to understand what was influencing how and why this person was presenting in this way at this time. I like to think of it as a way to remember that the person seeing you is a person-in-context.

We can argue the toss about exactly which factors belong in which “bit” of a biopsychosocial approach, but broadly speaking, we want to understand biological influences on health. Some of these are genetic (a bit hard to investigate for most of us), some of these are environmental (rickets? Vit D deficiency?), some are other organisms (M. leprae and M. lepromatosis? – Leprosy to you and me). Some are associated with what people do – tripping, jumping off things; while some are associated with what people don’t do – manage diabetes, exercise. The bio part is far more readily assessed and addressed than the other messy bits and pieces, so I won’t deal with that any further.

The psychosocial, on the other hand, is messy. It’s muddled and hard to measure and changes over time and geography and culture.

To me, it means remembering that when two people get together, it’s not just about the words we use, it’s about what we both bring to the setting in terms of experience, habits, expectations, vulnerabilities. It’s about where we meet. It’s about the purpose of meeting. It’s about recognising that everything we say and do is imbued with meaning – but it’s also about not necessarily knowing what we know, or what we don’t know.

So if I’m practicing in a biopsychosocial framework, I’m going to have to know a great deal about myself and my assumptions, my attitudes, habits, how others see me, and even what I don’t know. And the same applies to my knowledge about the person I’m seeing – only because I’m usually the “treatment provider”, I need to shape my conversation so that it’s OK for that person to tell me about this stuff, and this means knowing a bit about how people tick. I especially need to know how to hear what the person coming to me is saying – and not saying.

I see much that is called “psychological” as being about how we communicate and what we know about helping people change behaviour. I’m not “doing psychology” when I teach my child how to tie shoelaces, yet I’m using psychological techniques – modeling, reinforcement, verbal instructions and so on. Likewise when I’m helping someone feel OK about driving their car when they have back pain, I’m using psychological techniques such as verbal instruction, grading the difficulty, encouraging, supporting and so on. To suggest we can’t use psychological techniques to enable normal function is unthinkable.

Using CBT or ACT or motivation interviewing simply means refining my interpersonal skills so that I can optimise the chances that the person feels heard, can understand what I’m on about, and begins to feel OK about taking steps towards the life they want and being themselves. It’s about learning ways of explaining things, learning how to show that I’m listening, learning about the right level of support and challenge that will enhance the chances of success. Most people who live with chronic pain probably don’t need to see a psychologist – they need someone to help them make sense of pain, to show they’re there as they find their way through, and celebrate when they’re doing what’s important in their lives. I think all health professionals should be doing this.

How much do you really need to deal with catastrophising?


Catastrophising is a popular concept in pain management. It’s been associated with poor outcomes in major joint replacement (Riddle, Wade, Jiranek and Kong, 2010); spinal fusion (Abbott, Tyni-Lenne & Hedlund, (2010); in experimental pain modulation (Bartley & Rhudy, 2008); in cancer pain (Bishop & Warr, 2003); and influences interpersonal relationships (Buenaver, Edwards & Haythornthwaite, 2007).

I’m often asked: so, what do I do about it? Can it be treated? What does it really mean? Should I (any kind of non-psychologist) try to treat it, or should I leave it to the psychologists?

The short answer is, I think, yes we need to be aware of catastrophising, yes we can do something to help people become less likely to catastrophise, and yes I firmly believe any and all health professionals have a contribution to make to reduce the tendency to catastrophise simply because it can be so influential for distress, function and disability.

What does catastrophising really mean?

Catastrophising is, basically, the tendency to think the worst about a situation. It probably has some adaptive function in that it helps people identify all the things that can go wrong so they can do something to reduce that risk. On the other hand, it’s not such a wonderful thing when it leads to ruminating (brooding), feeling helpless, and to magnify (or emphasise) all the disasters that could happen, when the probability is really quite low (Sullivan, Bishop & Pivik, 1995).

It’s likely that most of us will have, at one time or another, anticipated the worst. Most of the time the worst doesn’t happen, and we go our way, reassured that we’ve planned for, and managed the situation more effectively than if we’d carried out regardless. But for people who tend to catastrophise about their pain, the risk is fairly high that they’ll experience more distress, depression and disability than those who don’t.

I want to point out that identifying that someone tends to catastrophise does not mean their fears should be dismissed out of hand.  The person who tends to catastrophise is likely to disagree with you, feel their concerns are being trivialised, feel rejected and less likely to talk to you about their concerns. Not the way to maintain a therapeutic relationship!

How can you tell if someone’s catastrophising?

The main assessment measure of catastrophising is Sullivan, Bishop & Pivik’s “Pain Catastrophising Scale“.  It’s not the only measure, but it’s one of the most well-known. It’s relatively brief, and has excellent psychometric properties. But if you’re not comfortable using a pen and paper measure, how else can you decide if someone’s tending to think this way?

Some good questions to ask are:

“What do you think is the most likely outcome of this [procedure/painful event]?”

“How are you feeling about this pain?”

“What can you do to help yourself when your pain is like this?”

“How much can you distract yourself from the pain?”

“What do you think this pain means? What’s your theory about this pain?”

If the person answers negatively – for example, they say they can’t even think about an outcome it’s so bad, or they don’t think it’s ever going to get better, or it’s “terrible”, or “awful”; if they say they can’t distract themselves from the pain, they keep thinking about it all the time; and if they think there’s nothing they can do to help themselves, they feel helpless or hopeless; and if they think the pain means something sinister or bad – then you’re likely to have identified someone who is appraising their situation more fearfully than is helpful.

If the person says “Oh but it really is that bad!”

Remember when you were a kid and were terrified of the dark, or bugs, or things under the toilet lid? or when you were really upset and someone said “Calm down!” – remember that flash of anger that the other person was just not aware of how terrified you were? Simply disagreeing or correcting someone is not going to reduce their anxiety.

I find that first of all it’s important to reflect to the person that you understand they are really worried by their pain. Saying something like “It seems that your pain is really bothering you, and you’re really worried about what it means now and might mean in the future. Have I understood you correctly?”

I then find it useful to unpack the specifics of what the person is really worried about. I might ask “When you say the pain is terrible, what does that mean? What do you think might happen?”

What I’m trying to do is reduce the global appraisal the “everything” is “awful”. I want to find out the details, the underlying beliefs that are underneath the fearful appraisal. So, for example, if the answer to the question above is “I feel like I’m going to die, I can’t breathe and it’s frightening” or “I think it’s never going to end, it’s going to be there all the time, forever”, I can begin to gently reality test these beliefs and also provide some skills to help the person get through them.  I firstly reflect what I’ve heard: “It sounds so scary, not to be able to breathe – no wonder you’re feeling afraid” or “I’d be worried too, if I thought my pain was going to be there all the time, forever”.

Then I might begin suggesting we work on ways to handle the emotions associated with this belief (it’s very hard to reality test if the person is very distressed). “I wonder if we could just spend a minute looking at some ways to help you deal with your feelings, so they don’t wind your nervous system up more? Even if it’s frightening, it’s hard to deal with when your body is getting very stressed, so tell me, what do you find works well to help you calm down?” I might either use what the person says, or teach some diaphragmatic breathing and mindfulness.

Then it’s often a good time to work through a nonthreatening explanation of pain. There are so many ways to present this – YouTube videos of Lorimer Moseley “explain pain”, or Mike Stewart “Know Pain”, or the 5 minute pain video by Hunter Integrated Pain Service. Or you can use your own explanations and metaphors that are meaningful to the person. A case formulation can be helpful too.

When should you refer to a psychologist?

I think most people with chronic pain are fine just learning simple skills like breathing, mindfulness and gently approaching movements that they’ve been worried about doing. Even better if this is carried out with a strong eye to what the person can do and wants to be able to do in their everyday life. Success does breed success.

But there are a percentage of people who really struggle with catastrophising. If you find that the person you’re working with can’t use breathing to calm down, finds it really difficult to stop brooding (especially if this is going on all night!), or finds it very hard to accept a different way of viewing pain, then it’s time to work together with a psychologist to develop an approach that combines what you do (restoring occupational engagement or function) with cognitive therapy or ACT (Acceptance and Commitment Therapy). I personally find it’s people who have very rigid beliefs about their pain, about how the world works, and who find it difficult to experiment and try new things that need this kind of input.

So – should we think about catastrophising in our clinical work? Definitely yes. It’s too important to omit. Should we help people who tend to think this way? Definitely yes, it’s not necessarily the remit only of a psychologist, and I’d argue that we ALL need to contribute.

Accepting pain – or are we measuring something else?


Acceptance. Ask a person living with chronic pain whether they accept their pain and the answer is highly probably a resounding “No!”. It’s a word that evokes resignation, feeling helpless and giving up. Or at least that’s what many qualitative papers seem to show (Afrell, Biguet, Rudebeck, 2007; Baker, Gallois, Driedger & Santesso, 2011; Budge, Carryer & Boddy, 2012; Clarke & Iphofen, 2007; Lachapelle, Lavoie & Boudreau, 2008; Risdon, Eccleston, Crombez & McCracken, 2003). I remember when hearing a person tell me “Oh I accept my pain” thinking that this was often a clear indication that underneath it all, the person was pretty angry about the unfairness of pain impacting on their life.

Acceptance is defined in Acceptance and Commitment Therapy (ACT) as “a willingness to remain in contact with and to actively experience particular private experiences (Hayes, Jacobson, Follette, Dougher, 1994) (eds): Acceptance and Change: Content and Context in Psychotherapy. Reno, Context Press, 1994), and from this Lance McCracken and colleagues developed the Chronic Pain Acceptance Questionnaire. This measure has two dimensions: willingness to experience pain and engaging in values-directed activity despite pain.  The other way acceptance has been defined draws from self-regulation, and argues that withdrawing from goals that can’t be achieved, in order to turn to goals that can be achieved is a positive way to cope with life – acceptance is defined as disengaging from a goal to get rid of pain and instead, re-engaging in other goals that aren’t affected as much by pain.

Lauwerier, Caes, Van Damme, Goubert and Rosseel (2015) have recently published a paper reviewing the various instruments that purport to measure pain acceptance. In their analysis, a coding scheme was developed consisting of the three main aspects of acceptance that seem to represent the concept: disengaging from controlling pain, pain willingness (in certain circumstances), and engaging in other valued activities. These three concepts were drawn from the literature – and then there were the left-over concepts that were also present in measures of acceptance. These are the interesting ones!

The addition five codes were: controlling pain, pain costs, pain benefits, unclear and no fit.

They identified 18 difference instruments, of which five didn’t specifically measure acceptance of chronic pain or illness and were therefore excluded from the study, leaving 13 measures to review. The one mentioned the most in the studies reviewed was the Chronic Pain Acceptance Questionnaire-2o.

Moving on to the results, what did these researchers find? And of course, why does it matter

Well, most of the instruments were measuring aspects of acceptance – the Brief Pain Coping Inventory, Chronic Pain Acceptance Questionnaire-A and CPAQ-20, and the Pain Solutions Questionnaire. The original CPAQ and the PASOL were the only two measures with moderate (but the highest percentage) of items with all three acceptance features (disengagement from pain control, pain willingness, and engaging in activity other than pain control), and interestingly, most instruments included “engaging in activities other than pain control”, while the other two factors were less well-represented.

Even more interesting is that many of the items in these instruments were classified as “controlling pain” – in other words, measuring how willing individuals are to carry on with life without trying to control pain. At the same time, many of the instruments also measured “pain costs” – such as “because of my illness, I miss the things I like to do best”.

Then these researchers did some pretty fancy analysis, looking at dimensions contained within all the items from all the measures. What they found was a 2-dimensional solution, with one dimension going from “fully engaged in valued activities” (my description!) to “pain costs”, and the other axis going from “pain willingness” to “controlling pain”.

Conclusions and why this is important

Most of the assessment measures contained some of the concepts thought to be important in pain acceptance, but the aspect most commonly found was engaging in activities other than controlling pain. Items measuring disengaging from trying to control pain, and pain willingness were found less often, while many measures incorporate pain control, and some that reflected pain costs or were unclear. This research seems to show that engagement in activities other than pain control and pain willingness are key features of items measuring acceptance, but at the same time show that not many measures look at both of these concepts together.  Additionally, this research shows that many supposedly “acceptance” instruments actually measure attempts to control pain but then reverse score these items – this can mean that people using these measures interpret them as avoidance measures rather than willingness to experience pain – appealing to quite a different theoretical model (the avoidance or fear-avoidance model) rather than a pain acceptance model.

Why is this research important? Well, acceptance is still a relatively new concept in pain research and clinical practice. While it has been talked about a great deal, and there are numerous studies of acceptance, the instruments developed for such research have not been around very long, and as we can see, don’t always adequately represent the fullness of the theoretical domains. Some aspects are not well-represented or are at risk of being misinterpreted. What works in a research setting may not always be accurately transferred to a clinical setting, especially if clinicians pick up a new measure without reading the theoretical basis for its development.

I also argue on the basis of my research that “disengaging from trying to control pain” doesn’t only need to be represented by items suggesting that people no longer seek treatment. From my findings based on people who live well with chronic pain, treatment is still a feature – but the investment in the outcome of treatment is far less. It’s less important that the pain is removed, treatment is “an option” rather than a necessary part of “returning to normal”.

I also argue that pain willingness is conditional upon the values placed on the activities the individual wants to do. So, if the activity is boring, unpleasant, hard work or doesn’t have rewards to the individual, the person is more than likely to avoid it, but if it’s highly valued then pain becomes a less dominant factor in the decision to do it.

Why should clinicians care? Because acceptance is an exciting and fruitful aspect of living well with pain that we can incorporate into our treatments. Acceptance is about learning to live well, “being with” or “making space” for the presence of pain, so that the other aspects of life are able to be engaged in. That’s important given how few people can have their pain completely reduced.

An allied health response to primary care for musculoskeletal aches and pains


For as long as I can remember, the joke about doctors saying “take two paracetamol and ring me in the morning” has been a pretty accurate reflection of reality – but no more perhaps?

A large review and meta-analysis of randomised placebo controlled trials of paracetamol in back pain and osteoarthritis has found that although paracetamol can provide a limited reduction in pain in osteoarthritis but not at a clinically important level, there is an elevated risk (four times) of having abnormal results on liver function tests (Machado, Maher, Ferreira, Pinheiro, Lin et al, 2015). The meaning of this elevated risk on liver function isn’t clear, but what is clear is the very minimal effect of what has been used as a mainstay drug for two of the most common complaints in the world.

Oh what are we to do? Because if the findings about paracetamol are stunning, add to it the clear evidence of harms associated with nonsteroidal anti-inflammatories, and we have a situation where the two most common front-line treatments for musculoskeletal pain are being strongly questioned. What’s a busy GP meant to do?

As a community, I think health professionals working with people who have musculoskeletal pain need to begin a concerted campaign to show the value of nonpharmacological approaches to managing life with aches and pains. We already have this beginning with some of the physiotherapy social media campaigns – see a physio first! But I think we could add “See your allied health team first”.

What would it mean to see an allied health professional first? And what would allied health professionals need to do to make this a valid option?

I think allied health professionals would need to make some changes to how we assess people presenting with pain – I wouldn’t want to ban the biomechanical, but here’s a question: how well do physiotherapists consider the psychosocial in their history taking? Luckily I don’t need to have the answer because Rob Oostendorp, Hans Elvers and colleagues have done the work for me.  In this study, therapists were observed conducting their first assessment with a new patient experiencing chronic neck or back pain. Their interviews were reviewed against the SCEBS (Somatic, Psychological (Cognition, Emotion and Behaviour) and Social dimensions of chronic pain), and given scores for how well the interviews explored these domains. Perhaps unsurprisingly, history taking for the Somatic dimension (how sore, where are you sore, what triggers etc) was excellent, with 98% including this area. BUT, and you’d expect this perhaps, Cognition was 43%, Behaviour was 38%, Emotion was 28%, and Social was 18%. What this means is that despite the clinicians themselves considering their coverage for all but the social domain as being “adequate”, in reality the only aspect that these clinicians covered well was the most basic area – “what does it feel like?”.

Challenging indeed.

Now, what would happen if we then examined what these clinicians do with that information? Because if we’re not so wonderful at collecting useful information across domains, my bet is that we’re even worse at combining this information to make sense of it – in other words, developing useful formulations.

Unfortunately I don’t have any information on how we as allied health clinicians use the information we collect, but if my experience as an educator and the very limited number of papers discussing formulations is anything to go by, I don’t think we’re doing too well. I suspect we tend to collect information then blithely continue doing what we’ve always done in terms of treatments. And I’m sorry I don’t have the evidence to support my hunch – would someone take this on for a project, please?

I think allied health professionals also need to make some changes to how we present what we do to the general public. While most people in the general public know that physiotherapists help people move, osteopaths are gentle and work with their hands, chiropractic looks after backs and necks – I’m not so sure anyone really knows what occupational therapists might offer, and I’m certain there would be some angst if psychologists were recommended as front line clinicians for musculoskeletal problems!

You see, while we’ve been concerned about a biomedical dominance in musculoskeletal pain, we haven’t been as good at helping the general public recognise that aches and pains are fairly common and often not a sign of pathology. We’ve been pretty poor at showing the value of relaxation, mindfulness and down-regulation as useful ways to deal with pain. We haven’t addressed the need to engage in occupations and activities that are fulfilling and enjoyable and enriching. In fact, I venture to say that we have almost wholly bought into the biomedical model when it comes to how to conceptualise musculoskeletal aches and pains. We are as guilty as anyone for considering an ache or pain as a sign that the person needs to be “fixed” or “mended” or “aligned” or “stabilised”.

I think a more radical approach, and one that allied health professionals can really endorse because there is evidence for it, is that living well involves being fully human beings. That means allowing ourselves to engage in what we love to do, to not only be active but also to relax, to be exuberant and to be peaceful. To think of our lives as a whole, rather than an isolated ouchy hip or knee or neck. And to look to our whole lifestyle as key to living well rather than “treating” the bit that happens to be bothering us right now.

Imagine that – an allied health workforce that puts out the message that life and wellbeing are the products of balancing all the wonderful facets of being human.
