@Invisible Woman and
@Nellie Pledge have explained the problem very well.
@Invisible Woman needed to work through feelings of boredom to get the rest she needed, and she needed long, flexible periods of rest (sounds like both pre-emptive and recuperative but correct me if I’m wrong there
@Invisible Woman). Had she done the Ho Yen programme after this study, she would have been told to limit her pre-emptive rest periods to 30 mins, and this would have been the wrong recommendation for her.
@NelliePledge explains that different people need different permutations and combinations of rest, both in terms of duration and nature, e.g. some will do best with music or meditation or a nap.
I have heard many patients say that there’s a delicate balance between resting enough for ME and not resting so much that they’re miserable.
I know that I need much longer periods of both pre-emptive and recuperative rest than 30 mins at a time, and have throughout the many severity levels I’ve experienced. Do I get bored sometimes? Sure. I’ve learned that that’s part of what getting what I need for my ME, and I’ve learned how to troubleshoot it. I’ve learned that a bit of boredom is preferable to my ME flaring horribly. I have to be much more isolated than I want to be in order to keep my ME at a level that allows me to maximise how much contact I have with people. So yep, gotta suck up some feelings of isolation.
I personally don’t get depressed, but I can see that if someone has clinical depression or anxiety alongside their ME, certain types of rest might exacerbate that, and they may need to manage things differently for a while to optimise the management of the two conditions. Similarly I can see that if someone is actually resting more than they need to, that would potentially be annoying, and should be reduced. For those individuals.
In scientific terms, we have an unevaluated recommendation that is potentially unhelpful ME-wise for the majority because of an unreplicated finding of 3 patients meeting Oxford and Ho-Yen criteria in a non-randomized trial with no active control who may have had untreated anxiety or depression (see below).
When the recommendation gets referred to in other papers without that important information (unevaluated, unreplicated, 3 people, non-randomized, no active control, untreated anxiety or depression in almost half of participants, small sample 22 patients), or when people evaluating evidence are not aware of the importance of that information, we can end up with unfounded recommendations making their way into guidelines. Our field is particularly prone to this because there is just so little research compared to other conditions. And we're particularly at risk of such an unfounded recommendation ending up in the new NICE guidelines because the current NICE guidelines already contain a completely evidence-free recommendation to restrict rest periods to 30 mins.
I'm going to use the term ME because that's how I've drafted this post and because recommendations for CFS tend to be applied to all, but Goudsmit, Ho-Yen and Dancey used the term CFS.
This was a very small trial – just 22 patients meeting Oxford criteria and Ho-Yen’s own criteria (and 22 controls). Patients were not randomized. Nearly half of those “recorded scores above the cut-off point for possible clinical anxiety and depression”. The authors mention that some participants would probably have benefited from referral to a therapist or more time discussing their emotions with the consultant. They recognize this as a limitation of the trial. So some of the patients, up to 10, potentially have under-treated pre-existing anxiety or depression during the trial. We’d expect that if we asked that group about their feelings at any time point, at least some of them would report “negative” feelings, regardless of whether they were or were not responding to treatment.
Despite this, at six months there was a “small reduction in the number of cases of possible anxiety and depression among the treatment group but not among the controls”. So the group did not become more anxious or depressed after the treatment, they became slightly less so.
But because
three patients described the pre-emptive rest periods as ‘‘boring’’, ‘‘isolating’’ and ‘‘depressing’’, a recommendation was made to reduce pre-emptive rest times to 30 mins for
all patients.
That recommendation was not evaluated – so we don’t know the effect of this reduction in pre-emptive rest on the three patients who found it challenging emotionally, and we don’t know the effect of this reduction on the 19 other patients who did not find the pre-emptive rest periods challenging emotionally. It’s possible that the change would have helpful for the 3 patients emotionally but
unhelpful for the other 19 patients ME-wise. It’s possible that the change would have been helpful for the 3 patients emotionally but unhelpful for their ME, and that what they really needed was help for pre-existing anxiety or depression.
There are plenty of alternatives to the recommendation to reduce pre-emptive rest periods for all such as:
· Check how the patient is doing ME-wise and if feeling relatively well ME-wise but finding rests challenging emotionally, then suggest that that individual patient experiments with shorter pre-emptive rest periods. If their ME remains fine, then they may have just been resting too much. Leave the other patients as they are.
· Treat patients for anxiety and depression
· Include advice in the programme for what individuals can try if finding pre-emptive rest periods boring, isolating or depressing: suggestions could include changing the nature of the rest period by listening to music or an audiobook while lying down with eyes closed, or experimenting with the timing and length of rests to see what suits them best as individuals, or advising patients that this may happen so that they know to expect it, or talking with their therapist about whether they might be resting too much e.g. if they’re actually feeling relatively well ME-wise
Most importantly all of this needs to be evaluated in a larger, randomised trial and replicated in other trials before it should be recommended at all, and definitely shouldn't appear in something like the NICE guidelines.
As I understand it, that old trial by Goudsmit and Ho Yen used pre-emptive rest which probably meant patients were instructed to rest completely (no reading or tv but more or less doing nothing) even though they felt they could do more without facing PEM. This wasn't helpful and apparently on some patients it had a detrimental effect because they were so bored.
It's important to distinguish between ME and emotions here. The results showed a significant difference between groups in fatigue. So it was helpful for one of the main ME symptoms, albeit in a trial without an active control. Depression and anxiety rates did not go up, they went slightly down for the treatment group, and significantly so for anxiety. So it was also somewhat helpful for depression and anxiety. 3 of 22 people, of whom almost half had HADS scores indicating potential anxiety or depression, felt bored/isolated/depressed while they were doing their pre-emptive rests. That's it. We don't know how the 3 people fared ME-wise - it's possible that their ME improved, and we don't know if these feelings during their rests translated into any meaningful change in their overall mental health.
But as I've mentioned before, If you do not refer to the studies by Jason and Goudsmit - who have published the most about pacing in ME/CFS - then it seems that everyone is free to make of pacing what he/she wants it to be. I haven't heard from those rejecting the Goudsmit/Jason consensus document how they would adress this problem.
I'm not suggesting not referring to any studies by Jason and Goudsmit. In my post above I suggested the opposite - looking at their other publications to find a good description of pacing that doesn't include GET programmes. I think they've both done/are doing really valuable work and we're lucky to have (had) both of them working in the field.
I didn't suggest NICE should take over all the info from the Goudsmit/Jason paper as if it was some sort of manual, I simply want it used to demonstrate that there is a consensus around pacing in ME/CFS that is very different from what pacing means in the chronic pain literature and the research by Antcliff et al.
Yeah, I get that. I'm just urging caution with that particular paper for the purpose you described. I'd go with another one/few. Of all the publications by Goudsmit and Jason that I've read, that's the one that comes closest to the Antcliff version of pacing, because it goes into such detail about increasing activity. That little paragraph that specifies prerequisites for starting GET is not strong enough or emphasized enough, in my view, to combat the overwhelming pressure to get us to increase activity/exercise. The studies reviewed after that paragraph do not have those prerequisites. If the committee were composed differently, I wouldn't be as concerned. My point is simply that things that you intend for one purpose can be used for another by people who have opposing views or don't understand the issues.
