ME/CFS Science @mecfsscience.org · 14/09/20265) I think the document make some sensible recommendations but I also have strong doubts about some of the threshold they use. For actigraphy they use a cutoff of <2300 steps/day which is quite low. Many patients with mild-moderate ME/CFS will have more steps than this. 2142

For fatigue they recommend the Chalder Fatigue Scale (not a good choice!). 190
