Effects of Menstrual Cycle Phases on Gait, Pelvis, and Sleep

This study aims to investigate the effects of different phases of the menstrual cycle on gait spatiotemporal characteristics, pelvic kinematics, and sleep quality in healthy women aged 18-35 years with regular menstrual cycles. Participants will be assessed in three phases of the cycle: early follicular (days 1-3), ovulation (days 7-9, confirmed by ovulation test), and luteal (days 20-23). Gait parameters and pelvic kinematics will be evaluated using the BTS-G walk sensor system, while sleep quality will be assessed with the Pittsburgh Sleep Quality Index (PSQI). The study seeks to determine whether physiological and hormonal changes during menstrual phases lead to measurable differences in gait, pelvic motion, and sleep quality.
