Orthostatic stress testing in myalgic encephalomyelitis/chronic fatigue syndrome patients with or without concomitant fibromyalgia: effects on pressure pain thresholds and temporal summation.

CONCLUSIONS: Pressure pain threshold decreased in ME/CFS patients with or without fibromyalgia after head-up tilt test (HUT), but did not change post-HUT in healthy controls. Windup pre- and post-HUT was significantly higher compared to healthy controls, but did not change from pre- to post-HUT. These results demonstrate that, like exercise, orthostatic stress can negatively influence the physiology of pain perception in ME/CFS. Furthermore, the physiology of pain perception is even more negatively influenced by concomitant fibromyalgia. PMID: 32940215 [PubMed - as supplied by publisher]
