Abstract: The purpose of this study was to investigate the effect of the three
phases (menstrual, follicular, luteal phase) of the menstrual cycle on active
and passive ankle joint position sense. Twenty five healthy women with regular
menstrual cycle, not pregnant and no contraceptive using with normal and
consistent length of menstrual cycle and bleeding days participated in the
study. Blood samples were collected from each subject for determination of
hormonal level the phases of menstrual cycle. Ankle joint position sense
changes during three different phases of the menstrual cycle were assessed.
Active and passive joint position sense of dominant leg of subjects was
measured using the Biodex 2 isokinetic dynamometer. The absolute reposition
errors from the target angles have been evaluated by repeated measure analysis
of variance (ANOVA) in three hormonally verified phases of menstrual cycle. No
significant interaction was observed between ankle joint position sense test
and the phases of the menstrual cycle. We did not identify ankle joint position
sense alteration across the menstrual, follicular and luteal phases. We suggest
that the menstrual cycle does not significantly affect ankle joint position
sense.
