The effect of shoe fit on the gait stability of the older adults

Abstract

Objective: To investigate whether fit shoe affects gait stability of the older people using shoe of different sizes with uniform shoe types and characteristics.

Methods: 27 older adults who participated in the disability prevention experience were included in the study. To assess gait ability, we used a tri-axial accelerometer to calculate RMS, walking speed, step length, variation in gait cycle. We used Brannock device to measure shoe size, and prepared shoes that matched the two conditions of fit and non-fit. The subjects were randomized to wear the shoes, and their gait ability was measured. Statistical analysis was performed paired t-tests corresponding to the comparison of gait-related indices in shoe fit.

Results: Comparing fit vs. non-fit, only the anterior-posterior RMS was significantly lower (smaller sway) when the non-fit shoes were worn.

Conclusions: It is possible that the propulsive force during gait may have been affected, but further study is needed.
