Abstract

The purpose of this study was to determine a relations with age and quiet standing stability of elderlies, and to compare a standing stability of female and male elderlies through a analysis of COP(center of pressure). Healthy female(n=10, age: 76.00±4.37) and male(n=10, age: 77.70±3.30) elderlies participated for this project. The measurement was processed each distance and 95% confidence ellipse area of COP in those variations undergoing comfortable quiet upright standing with term interval 5 seconds, 6 sections, and overall 30 seconds. Correlation of Spearman analysis was performed age with COP factors by Pearson in two ways. Independent sample t-test was practiced for the comparison of female and male elderly groups with statistical significant level of .05. Significant result was not appeared in correlation age with factors such as distance and area. Female elderly group had a greater COP sways of distance and area than male elderly group during quiet upright standing, and COP distance offering significant data in terms of 0~5s, 6~10s, 16~20s, 21~25s. Standard Deviation(SD) data of female elderly group were greater than male elderly group over all of 5sec terms in COP distance and area. All of participants need the times(0~15s) for adapting of the initial stability posture, they showed decreasing of sways and firm stabilities since then. In conclusion, Stability of standing posture in elderlies can vary as the health and fitness condition of them. In other words, age is not the only balance decreasing factor in physical. And ability of upright standing from each individual had a wide gap in female elderly group. Female elderlies have more sways than male elderlies in stability posture, some intervention of prevent fall is demanded for female elderlies such as a specific balance program.
