Chronic fatigue syndrome and myalgic encephalomyelitis are fatiguing illnesses that often result in long-term impairment in daily functioning. In reviewing case definitions, Thrope et al. (Fatigue 4(3):175-188, 2016) noted that the vast majority of case definitions used to describe these illnesses list a "substantial reduction" in activities as a required feature for diagnosis. However, there is no consensus on how to best operationalize the criterion of substantial reduction.
