Factors associated with night-time calf muscle cramps: a case-control study.

摘要: Introduction: Although highly prevalent and painful, night-time calf muscle cramping is poorly understood, no treatment has shown consistent efficacy or safety. Methods: One hundred sixty adults were recruited from New South Wales, Australia, including 80 who had at least once per week age- gender-matched did not. Participants assessed using reliable tests of lower limb strength, flexibility, morphometrics, circulation, sensation, questioned about health lifestyle factors, diet, medications, exercise, symptomatology, sleeping habits, footwear. Results: Conditional logistic regression identified 3 factors independently associated with cramps: twitching (OR 4.6, 95% CI 1.6–15.5, P = 0.01); tingling 4.1, 1.6–10.3, 0.003); foot dorsiflexion weakness 1.02, 1.01–1.03, 0.002), which represented other measures in the model. Conclusions: Night-time cramps markers neurological dysfunction potential musculoskeletal therapeutic targets. Muscle Nerve 47:339-343, 2013
