The Harvard article is another demonstration of either the schizophrenia or the unthinking nature of "evidence-based" medicine when it comes to ME. Mixing and matching good biomedical disease evidence with BPS management practices without apparently thinking whether it makes medical sense for those things to be stuck together.
While there are still some errors, the article does a reasonable job describing the nature of the disease, the demographics, the evidence of pathophysiology, etc.
But the management section is this weird grab bag of "evidence" that mixes discussion about energy envelope/pacing (although still fear of activity) with CBT, GET, and a section on acupuncture, Yoga, Tai Chi, chiropractic, and massage that's particularly strange in how much emphasis they give it (about 1/2 of the whole section on treatment). Couldnt tell if they were padding the section out or they really believe this but there was a lack of ME specific evidence and no caveats on the risks - e.g. some of these can also cause PEM, are not appropriate if patients have severe OI, etc.
On GET, they acknowledge the issues with PACE and then conclude "Based on current evidence, the value of GET has been neither proved nor disproved." But they fail to mention AHRQ's finding of a lack of evidence of efficacy combined with evidence of harms from GET which should be the key point. They then go on to say that if you try graded exercise "Your program should be light enough to avoid exhaustion, but challenging enough to be invigorating and capable of increasing your strength and stamina." All in all, the content puts patients at risk of harm
Regarding CBT, it also states that is neither proven or disproven for CFS but then states "Advocates of CBT say it is most effective when it decreases a person’s perception of problems related to activity and increases the sense of control over." Ugh
