Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Fibromyalgia (FM) are two debilitating illnesses primarily characterized by chronic symptoms of fatigue and musculoskeletal pain, respectively. Some investigators have observed an elevated sense of effort in these patient groups, however, this effect has not been substantiated via quantitative review. As such, we conducted a meta-analysis of perceived exertion (RPE) responses to aerobic exercise in ME/CFS and FM compared to healthy adults.
