Abstract
Deformation of joint structures in flat foot individual was hypothesized to be a cause of ankle joint instability. Objective: To compare the ability to control static and dynamic ankle joint stability between flat foot and normal foot individuals. Methods: Healthy male volunteers with normal (n=15) and without flatfoot (n=15) were measured static ankle joint stability with one leg standing test (OLS) and dynamic ankle joint stability with functional reach test (FRT) and multiple directional reach test (MRT). Independent-t-test and Mann Whitney U test were used to analyze the data. Results: No differences between two groups were found in three conditions including the OLS test (eyes open: 14.84±9.48s VS.20.01±9.86s, eyes closed: 3.06±1.87s VS.3.82±2.18s), the FRT test (10.13±3.25 in VS. 11.91±1.98in) and the MRT test for left side (6.71±2.02in VS.7.49±1.11in), but there was significant difference in the MRT test values for right side (6.62±1.74in VS.8.10±1.43in, p<0.05). Conclusion: The ability to control static ankle joint stability in healthy male individuals with and without flat foot was not different. Statistically significant difference in dynamic ankle stability control between normal and flatfoot individuals may not be clinically significant.
