A Study of Postural Sway according to the Wedge Direction during one Leg Standing

Background/Objectives: Equilibrium is the ability to maintain the Center Of Gravity (COG) in their Base Of Support (BOS) and the human body to maintain balance. The purpose of this study is to healthy adults when wearing medial/lateral wedge, ankle posture was to evaluate the effect of the dynamic balance. Methods/Statistical Analysis: This study elected a healthy adult male 14, female 26 people that have no physical balance due to musculoskeletal and neurologic abnormalities, ankle instability. Tetrax interactive balance system was maintained for 30 seconds on each surface (plane surface, lateral wedge, medial wedge) on the one leg standing position. Tetrax interactive balance system results through the General Stability Index (GST), Weight Distribution Index (WDI), weight distribution was collected. Data was analyzed the within surface in comparison paired t-test and the between surface in comparison one-way ANalysis Of VAriance (ANOVA). Findings: In the comparison between each floor, there were significant differences in weight distribution index (p<.05), in visual conditions change between the stability index was a significant difference (p<.05). Weight distribution difference of left and right were significant differences between the medial wedge and flat from the eyes open (p<.05), The eyes-closed state was a significant difference in medial wedge, flat and medial wedge, lateral wedge(p<.05). Therefore, closing one's eye is considered during dynamic balance training to get the effect of improving result. Application/Improvements: Therefore, closing one's eye is considered during dynamic balance training to get the effect of improving result.
