ABSTRACT

Bae, S.W., Kim, J.I. Change the balance function with aging using computerized dynamic posturography. Exercise Science, 12(4): 747-758, 2003. The purpose of this study was to evaluate the balance with aging using the values of sensory organization test(SOT) and motor control test(MCT) of computerized dynamic posturography(CDP) in the healthy Koreans. To assess the balance, we studied equilibrium score of SOT and weight symmetry, latency, and adaptation scores of MCT in 72 Korean healthy population. We divided the population into two groups, 3rd decade and 7th decade of age. In SOT, we studied the contribution of each sense to maintaining equilibrium when other senses were either absent or provided with inaccurate information. MCT provoked autonomic postural reactions through a series of sudden anterior and posterior support surface translations. In MCT, we studied latencies in sudden translation of foot plate. In SOT, the range of median equilibrium scores were from 64 to 94 in 3rd decade group, 55 to 93 in 7th decade group. In MCT, during sudden anterior and posterior perturbation, weight symmetries were 102.9±7.9 in 3rd decade group and 106.3±9.0 in 7th decade group. Median latencies were 125.8-134.3msec in 3rd decade group, 132.6-141.8msec in 7th decade group. In toes up and toes down test of MCT the mean adaptation scores were 54 to 71 and 40 to 53 in 3rd decade group, 58 to 75 and 44 to 63 in 7th decade group, respectively. In conclusion almost all measures of balance were worse in elderly group compared with young group. The decrements in aged persons suggest decreased capacity to process sensory inputs. And this occurs most likely as a result of biomechanical or central processing changes.
