- Description
- Although highly prevalent and painful, night-time calf muscle cramps are poorly understood, and no treatment has shown consistent efficacy or safety. 160 adults were recruited from NSW, Australia: 80 who experienced night-time calf cramp at least once per week and 80 age- and sex-matched adults who did not. Participants were assessed using reliable tests of lower limb strength, flexibility, morphometrics, circulation and sensation, and were questioned about health and lifestyle factors, diet, medications, exercise, symptomatology, sleeping habits and footwear. Conditional logistic regression identified 3 factors independently associated with night-time calf muscle cramps: muscle twitching (OR4.6; 95%CI: 1.6 to 15.5; p=0.01), lower limb tingling (OR4.1; 95%CI: 1.6 to 10.3; p=0.003) and foot dorsiflexion weakness (OR1.02; 95%CI: 1.01 to 1.03; p=0.002), which represented other measures of lower limb weakness in the model. Night-time calf muscle cramps were associated with markers of neurological dysfunction and potential musculoskeletal therapeutic targets.
