Abstract
Background: Studies have shown an increase in oestrogen levels across the menstrual cycle (MC) with an increase in muscle strength and joint laxity independently. However no research has yet been conducted into whether a relationship is demonstrated between these two parameters. Objectives: Feasibility study to identify a correlative change in joint laxity and muscle strength across one complete MC. Method: Twenty female, British School of Osteopathy (BSO) students aged 24-45 who reported normal menstrual cycles (28-32 days) participated. Joint laxity at the metercarpo-phalangel (MCP) joint and handgrip strength were measured at three phases of the MC: menstrual (days 1-4), follicular (days 12-14) and luteal (days 19-21). Results: No significant variation or relationship in joint laxity or muscle strength could be detected during the three phases of the MC. Conclusions: No association was found between hand grip strength and joint laxity as measured by the Hyperextensometer and Dynamometer however, due to the variance in sex hormones found between females, individual variations and hormone analysis is further required to distinguish whether there is a relationship between these two parameters across the MC.
