12 questions about that article on treating chronic pain with more pain
Edited to add: Some thoughts on Invisibilia's response to the criticism:
They say the piece was about a "small subset of chronic pain sufferers": young people with the "rare condition" Amplified Musculoskeletal Pain Syndrome (AMPS). First, AMPS is not a "condition"âit's an umbrella term (one that, as far as I can tell, is not widely used outside of these type of treatment programs). According to Hoffart, it covers âjuvenile fibromyalgia, complex regional pain syndrome, localized pain, neuropathic pain, central sensitization syndrome.â So it appears to cover basically any unexplained/idiopathic neuropathic or functional pain syndrome in children and teens. I do not know how the pediatric versions of these syndromes may differ in prevalence (or anything else) from the adult versions. But, collectively, the adult versions are not rare in the least. Fibromyalgia alone is estimated to affect at least 4 million people (most of them women) in the U.S.
This story was clearly framed as part of a broader exploration of "how our culture's attitude towards pain has shifted over the past fifty years" so the idea that it was just about one condition and one program and "was not meant to serve as a commentary on all chronic pain experiences" is hard to buy. Plus, this story is part of a larger conversation about chronic pain. While these particular treatment programs are extreme and rare, the basic theory that unexplained chronic pain is caused by patients focusing too much attention on their pain/"conversionâ of emotional distress into physical symptoms/reinforcement through âsecondary gainâ/etc. is one that much of the medical community still holds.
It is not some radical new theory; it is a very old theory. More to the point, it has been the default theory until quite recently. The long history of just assuming that unexplained pain syndromes (that, not incidentally, mostly affect women) are psychogenic or fabricated and, consequently, not scientifically researching them and dismissing sufferers as âmalingerers, liars and hystericsâ has had implications for our understanding of chronic pain in general. And how we understand what is now variously called "amplified" or "centralized" pain has implications for many, if not all, people with chronic pain.
I am not against interdisciplinary pain treatment programs. I'm not against behavioral pain management techniques. I am certainly not against incorporating psychotherapy into any pain management approach.
I am against pretending we understand what is happening in "the mind" when what we really mean is that we don't understand what is happening in the body. I am against accepting unfalsifiable and highly implausible theories by default instead of doing actual science. I'm against treating patients on the basis of those unproven theories with unbelievably little regard for the potential harm to them if we are wrong.
Original post:
I donât know what questions the journalists asked the experts in this NPR story about programs that treat unexplained chronic pain conditions in kids by forcing them âto push their bodies until they are in tons of painâ in order to retrain their brains to ignore pain.
But these are the questions I would have asked them:
1) What evaluations do patients undergo before the program to determine that there isn't an undiagnosed condition or injury that explains their pain? Literally, what lab tests and imaging is ordered? How many specialists have independently reviewed their case? How sure are you (as a percentage) that you have ruled out every possible underlying cause of the pain before accepting a patient into your program? 2) Your program is based on the theory that the pain persists because patients focus on it. But what is your theory for how the pain begins? How do you explain experiences like Devyn's in which the pain began suddenly out of the blue?
3) There are many pain experts who believe that what you call "amplified pain" is indeed caused by an amplification of the pain processing system but is due to sensitization at the level of neuron, not mediated by psychological factors like attentional focus. What evidence specifically convinces you that your theory is the more likely one? And what evidence would convince you that your theory is incorrect? Is your theory falsifiable?
4) You theorize that the pain is an expression of emotional distress in kids who are "not in touch with their feelings" and "don't have the sophisticated emotional skills they need to manage in an increasingly stressful world." Given that girls are generally more emotionally intelligent and in touch with their feelings than boys, what is your explanation for why girls are disproportionately affected by these pain syndromes? And if your theory about the root cause of the pain is correct, wouldn't the factor that explains the gender difference then need to be something nearly universalâlike, say, sex-based genetic or hormonal differencesâto produce such a marked gender imbalance in the opposite direction? And if thatâs the case, wouldnât that suggest that biological factors play a more important role than your theory allows for? 5) Many other experts in what you call amplified pain recommend exercise because of its physiological effect on the pain processing system. What makes you believe that any benefit from your program is due to the experience of pain and not the direct effect of the exercise itself? Have you done a study in which one control group got the exercise only (or the exercise, therapy, and breathing exercises) but without the focus on ignoring the pain? 6) Similarly, learning to distract yourself or even disassociate from the pain is a common way of coping with pain, both acute pain and chronic pain explained by an underlying disease or injury. Have you done a study in which you put patients with "explained" chronic pain conditions (say, rheumatoid arthritis patients) through the same treatment program? If patients with "explained" chronic pain report comparable reductions in pain wouldn't that suggest that what you are offering is not a treatment of the root cause of the pain but simply a (very unpleasant) way of teaching patients some pain coping skills? 7) Your program is rooted in a belief that you should not give more attention to patients' pain complaints. An asthma attack and a nosebleed are not pain complaints. What possible justification was there to ignore these problems in Devyn? 8) Upon completion of your program, what training do you provide to patients and their parents about how to differentiate between their existing pain, which they are instructed to ignore, and new pain complaints that may be a warning sign of an unrelated potentially life-threatening medical problem? 9) How did you get permission to implement this treatment program if the approach has never been proven safe and effective in large controlled studies? Do you inform patients and their parents of the untested, experimental nature of the program?
10) You believe that the alarmingly high and rising rates of chronic pain in the US are caused by the fact that American society has "focused way too much attention on aggressively relieving pain" and our medical system "asks patients to rate their pain on a scale of 1 to 10, and treats it like an emergency." How does this theory square with the overwhelming amount of evidence that pain is frequently undertreated in the US medical system, physicians get little training on pain management, and most continue to see pain as a diagnostic clue and not a problem in and of itself?
11) As our understanding of the neurobiology of pain has gotten progressively more sophisticated over the decades, many other previously inexplicable aspects of pain that we resorted to explaining in psychological terms have become explained in physiological ones (for example, phantom limb pain). Doesnât this history give you pause about the wisdom of resorting to psychological theories for pain that is currently âunexplainedâ?
12) You clearly believe wholeheartedly that your theory is correct. What if you are wrong?
