This study examined the relationship between ability to maintain a stable posture on an unstable stool (involuntary stimulation test: IS test) and physical functions and fall experiences in the female elderly. The subjects were 137 elderly female (age, 76.6 +6.2years; height, 147.8+5.4cm; weight, 49.3+7.5kg). Physical functions included isometric leg strength, and balance ability. They were administered the above-stated various tests and surveys on fall experience. The relationships between each parameter were examined by Pearson's correlation coefficient. The differences between the non-fall group and fall group in stable index was examined using unpaired t-tests. The significance level in this study was set at p < 0.05.Significantly lower correlations were found between the IS test and the one-leg standing with eyes open (OLS) test (|r|= 0.23), and between the IS test and the functional reach (FR)test (|r| = 0.26).In addition, non-fall group was superior in ability to maintain a stable posture on an unstable stool compared with fall group. In this study, we found a significant relationship between the IS and the OLS tests, and between the IS and the FR tests; however, it was not high. The IS test is related to a different ability than the OLS and FR tests. |
