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

Turkey (Türkiye)40 participantsStarted 2025-06-01

Plain-language summary

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
