The effect of medial longitudinal arch height and medial longitudinal arch support insoles on postural balance in perimenopausal women

Background/aim: Changes in balance and postural control have been reported during the perimenopausal period. We investigated theeffect of medial longitudinal arch height and medial arch support insoles on postural sway and balance in middle-aged perimenopausalwomen.Materials and methods: 29 women with normal arches and 29 women with low arches were included in the study. The foot arches of theparticipants were determined using the arch height index. The static balance index (SBI) measured by Kinesthetic Ability Trainer 3000and functional reach test were used to evaluate postural balance. Measurements were obtained from all participants with and withoutmedial arch support insoles.Results: The SBI-total scores without the insoles were found to be significantly higher in the lower arch group than in the normal archgroup. SBI-total, SBI-anteroposterior, and SBI-mediolateral scores significantly improved in the low arch group in the presence ofinsoles, whereas the usage of insoles resulted in no difference in the normal arch group. In the presence of insoles, the reach distances toleft and right sides increased in both groups, while the forward functional reach distances decreased.Conclusion: Medial longitudinal arch height and medial arch support insoles affect the balance parameters in perimenopausal women.
