Consumer-Contested Evidence: Why the ME/CFS Exercise Dispute Matters So Much

A biopsychosocial camp has contended since the 1990s that regardless of how it starts, people with ME/CFS dig themselves into a hole with their attitudes and behaviors, leading to physical deconditioning (sort of the opposite of getting fit). They argue that people can dig themselves out of it by changing their beliefs and behaviors with the help of cognitive behavioral therapy (CBT) and graded exercise therapy (GET).

***

ME/CFS groups see it differently. For them, the condition is more complex than fatigue and fitness, and believing you can recover won’t overcome it. From their experience and surveys since 2001, GET in practice causes relapses, worsening symptoms for most people; CBT doesn’t change the condition’s symptoms; and self-management “pacing” does help.

***

By the early 2000s, the biopsychosocial camp could claim a few small trials in support of their position, but it was a very weak evidence base. They saw their treatment approach as a good news story for patients, though, and they had a lot of supporters. Exercise is something of a sacred cow to many – including in the evidence community. So there was a constituency that wasn’t going to be as critical of studies claiming advantages of exercise as they might be for other treatments.

There was another powerful camp that was attracted to the idea that cheap short interventions could get rid of ME/CFS, if only the person was willing to make an effort: insurance and welfare stakeholders. It was in their interests to reduce treatment expenditure and income dependency for this fairly common condition. The close associations disclosed by ME/CFS researchers in the biopsychosocial camp with these policy communities have the potential to be conflicts of interest – and they are certainly seen that way by many.

It is good, especially for someone from outside the usual ME advocacy circles. This definition of pacing bothered me though. I blame @Action for M.E. for it a lot more than Hilda Bastian.

The UK group, Action for ME, describes pacing this way:

Taking a balanced, steady approach to activity counteracts the common tendency to overdo things. It avoids the inevitable ill effects that follow. Pacing gives you awareness of your own limitations which enables you positively to plan the way that you use your energy, maximising what you can do with it. Over time, when your condition stabilises, you can very gradually increase your activities to work towards recovery. [PDF]

Pacing isn't a treatment that assures your condition stabilises or, much less, that recovery is achieved.
Pacing doesn't involve 'very gradually increasing activities'. That sounds a lot more like 'graded exercise therapy' or the now more fashionable 'graded activity therapy'.

Subsequent posts related to pacing having been moved to a thread in Lifestyle Management:

I think it's really good for us to have someone like Hilda Bastion take the time to look into things like this, and then post a blog that is really supportive of patients and our right to engage in the debate around issues like PACE. It shouldn't be controversial, but it is, and it's great that she's raising concerns with a different audience, and doing so in a way that emphasises that this is something with lessons for those who have no real interest in ME/CFS.

Lots of really good stuff in there, eg:

Instead of responsiveness to criticism, some – not all – researchers have put massive effort into discrediting the whole community and rallying other researchers to their defense. It’s been a collective ad hominem attack. Being responsive when consumers are making mistakes or unjustified criticisms isn’t always easy, especially when there’s a barrage, with extremists in the mix. But it’s not only consumers who do that, is it? And there are important and legitimate issues here – not just people who don’t agree with the results.

It seems she's actually taken the time to read and think about comments from people like Courtney and Kindlon, and that's really great. (Does that sound patronising? I don't mean it to - I'm just so used to academics commenting on these issues without doing even minimal reading).

The conclusion:

As for the dispute over the validity of key methods here? I think the balance should, and ultimately will, tip towards the ME/CFS consumer movement on this particular contested evidence.

It's a wide ranging post, and as with any post about ME/CFS there are bits I'm a bit less sure on. I wondered if sometimes she simplified some of the GET stuff in a way that could lead to someone like White criticising her. I didn't see any bits that I felt sure were wrong. Maybe this is just a result of technical errors?

Although official processes have seen important data and other information released, the researchers have also removed a lot of material that used to be in the public domain. So much so, that it’s now impossible to assess for yourself some of the concerns, because the materials have disappeared. That’s bad enough for any research, but it’s unacceptable for a publicly funded clinical trial.

I wonder if that's just QMUL changing web addressed in annoying ways? It does also seem various documents go on and off line, but I get the impression that's more technical incompetence than anything else.
 
Generally a pretty good and welcome article. Thank you, Ms Bastian.

A couple of quibbles:

AHRQ argued that you need specific ME/CFS symptoms in your criteria – like experiencing post-exertional malaise. The PACE trial measured that specific symptom, because it was a secondary outcome.
Well, they asked a single self-report question about it, which I wouldn't call a reliable measure.
We don’t know how different approaches to exercise, “graded” or “paced”, really compare yet.
Pacing is not about exercise, it is about managing existing limitations on daily activity. If pacing is being tested as a rehabilitative or curative measure, then it will fail.
 
One of the authors of the planned Cochrane individual patient data review, the protocol of which was withdrawn, is my PhD supervisor, Paul Glasziou. We have not discussed it, and have not discussed anything related to this post while I was considering, researching, and writing it.

Paul Glasziou has been pretty bad for us, so I'd say that makes the blog even more impressive.

Can somebody give her a brief explanation, either on her blog or on Twitter, of why AfME's statement that "Over time, when your condition stabilises, you can very gradually increase your activities to work towards recovery." is much too broad and optimistic, compared to the patient experienced reality?
 
She is a star:angel:! See on her website;

So Far in January 2019
News for 2019: I'm pleased to announce that I'm now a regular contributor to BMJ Blogs. I'll be generally doing (shorter) versions of suitable posts from PLOS Blogs. First up:

Evidence and choice - what does one mean without the other?

And I updated my Twitter profile pic for the first time with one of my favorites.... Hmm... Too statistical?

I've posted these as the forum




 
I dare say, this has a whistleblower feel to it. I hope it encourages more people to speak up about things they saw from within that seemed odd and unethical but did not dare question the eminence of those in charge, especially given the obvious political nature of the whole psychosocial project.

I'm also thinking this may explain the internal deliberations at Cochrane that we glimpsed but could not really determine. I don't know if Cochrane always works in double super-secret and cryptic language but this may explain some of it.

Very well-researched article. This is quite a breakthrough. Is a COSMIDORCID required to comment? I'd imagine so, wanting comments from professionals and not random people?
