Abstract
Various medications and behavioral treatments for sleep-related leg cramps have been tried, but the quality of the evidence is low. Quinine seems to be effective, but dangerous. β-Agonists may be one of the more common causes of secondary leg cramps. Statins may not be implicated in leg cramps as much as has been believed. Potassium-sparing diuretics may have a higher incidence of sleep-related leg cramps than potassium-depleting diuretics. Plantar flexion of the feet may elicit most sleep-related leg cramps. More research into behavioral treatments is needed. A standardized sleep-related leg cramp questionnaire would be useful to expand research.
