Hormone status and measures of joint laxity.

Hormone status and measures of joint laxity. - 108 p.

Thesis (M.S.)--The University of North Carolina at Greensboro, 2007.

This study examined the relationships between oral contraceptive pill (OCP) use and measures of joint laxity. Methods. A menstrual history questionnaire identified 33 female athletes using OCPs. Separate stepwise linear regressions examined the extent to which OCP dosage (estradiol, progesterone) and SHBG% predicted measures of anterior knee laxity, general joint laxity and genu recurvatum. Secondary regression analyses examined the relationship between duration of OCP use and each joint laxity measure. Results. OCP dosage and %SHBG binding affinity were not predictors of joint laxity. Greater duration of OCP use positively predicted greater genu recurvatum (R2 = 20.8%, P=0.008). Conclusions. While the variations in dosages of common OCPs were not found to influence measures of joint laxity, prolonged exposure to these synthetic hormones may increase genu recurvatum over time. Further work is needed to clarify the effects of OCPs on joint laxity, a potential risk factor for knee injury.
