ME/CFS Skeptic

Bit confused now. Maybe if I rephrase my argument our differences will become clear. As I see it, the authors used different phrases to describe PEM from different case definition or questionnaires.Good catch! However, this is a part of how Ramsay describes MF:
One phrase that came from the Ramsay’s definition was “Prolonged worsening of symptoms after physical activity”. That one got the highest approval (89%) of ME/CFS patients. But this has little to do with muscle fatigability.
I suppose there were other phrases that came from Ramsay’s definition such as the phrases that refer to muscle fatigability. These however got much lower approval (around 70%).
That is lower than many phrases that came from the ICC such as ‘Symptoms worsen with exertion’ (87%) or ‘Post-exertional exhaustion that is immediate or delayed’ (85%).
So I don’t think it’s correct to say that muscle fatiguability is “more highly endorsed as a description of PEM than the actual descriptions given in ME-ICC.”
Hope this makes sense and that I’m not missing something.
