Abstract
The purpose of this study was to determine the effects of a MotoTiles exercise on balance ability in communitydwelling older adults. The participants were 11 women who lived in T city and had performed a community-group exercise. The exercise was carried out twice a week for a period of 12 weeks using the local community center. For the balance index, a 20-sec stepping test was performed with the eyes open, and the total head movment distance (TMD), maximum movment distance (MMD), and the distance of the knee joint point (KMD) were used using KINECTTM infrared sensor. The pace of both legs (PACE left and right) and its coefficient of variation (CV) were used using Optogait infrared sensor system. Functional reach (FR), up-and-go (TUG), and 30sec-chair stand (30-CS) were also examined. As a result of 12 weeks of exercise, there was significant improved on TMD, MMD, PACE left CV, FR, TUG, and 30-CS (effect size were moderate to large). No significant changes were observed in other infrared sensor-related indexes, but overall, the head and knee sway during the stepping test and the variation when raising the legs tended to be smaller. The MotoTiles Exercise appears to be useful for assessing one of balance ability in older adults.
