‘Pacing’ for management of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS): a systematic review and meta-analysis (2024)
Journal Article

Background

Pacing typically comprises regulating activity to avoid post-exertional neuroimmune exhaustion, the worsening of symptoms after an activity. Yet, the efficacy of pacing to improve symptomology is unclear.
Objective

We aimed to under... Read More about ‘Pacing’ for management of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS): a systematic review and meta-analysis.
