A preliminary study exploring the change in ankle joint laxity and general joint laxity during the menstrual cycle in cis women

Abstract Background The purpose of the present study was to examine relationship between ankle joint laxity and general (GJL) in relation menstrual cycle, which divided into four phases based on basal body temperature ovulation, assessed using an ovulation kit. Methods Participants were 14 female college students (21–22 years) with normal cycles (cis gender). Anterior drawer stress a magnitude 120 N applied for all participants. talofibular ligament (ATFL) length measured as linear distance (mm) its points attachment lateral malleolus talus ultrasonography. Data ATFL from each subject used calculate subject’s normalized change anterior (AD%). University Tokyo method evaluation GJL. AD% GJL once phase. Results There no statistically significant difference score significantly higher luteal compared early follicular showed positive correlation other Conclusions Although it is unclear whether estrogen receptors are ATFL, suggests that women high scores might be more sensitive effects estrogen, resulting
