This review looked at eight studies involving 1,518 people with ME/CFS to see if exercise therapy helps. When compared to usual care or passive treatments, exercise probably reduced fatigue somewhat in the short term, but we cannot be sure it helps long-term. When compared to other treatments like cognitive behavioural therapy, exercise did not clearly perform better or worse. The quality of evidence was often too low to draw firm conclusions about safety or effects on pain, quality of life, and other symptoms.
This comprehensive review directly addresses a key therapeutic question in ME/CFS management by synthesizing evidence on exercise as a treatment option. Clarifying whether and when exercise may be beneficial—versus potentially harmful—is crucial for patients, clinicians, and policy-makers making informed decisions about symptom management strategies.
This review does not establish that exercise is safe or universally beneficial for all people with ME/CFS; the evidence for serious adverse events is very uncertain, and most studied patients met specific older diagnostic criteria that may not represent the full spectrum of ME/CFS severity. The review also does not compare exercise to newer interventions or post-exertional malaise-informed approaches, limiting conclusions about best current practice. Finally, it does not clarify which exercise intensities, durations, or patient subgroups might benefit most or suffer harm.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
