Comparative Study
Physical activity level and physical performance in the 6-minute walk test in women with fibromyalgia.
Fibromyalgia (FM) is a chronic pain condition that causes impaired functional capacity, possibly through the adoption of sedentary behaviour. However, little is known regarding physical activity level and its relationship with physical performance in women with FM. ⋯ Women with FM had physical activity levels similar to women without FM but exhibited worse physical performance. This functional impairment may be related to lifestyle adopted because there was a relationship between physical activity level and physical performance in those patients.

Cutaneous silent period (CSP) is an inhibitory spinal protective reflex and its afferents consist of A-delta nerve fibers. We aimed to evaluate patients with fibromyalgia (FM) and healthy controls to determine any differences between the groups in terms of CSP duration and latency, and if present, to determine whether there is any relationship with disease characteristics, psychological disorders and quality of life. ⋯ CSP latencies in both upper and lower extremities in patients with FM are longer than in healthy volunteers. Moreover, prolongation of CSP latency in the lower extremity is associated with disease severity and physical functional disability.
