Objective:
@EN To study normal values of sensory organization t3est(SOT) and motor control test(MCT) of computerized dynamic posturography (CDP) in the healthy Koreans. Background : Balance is made up of three biological functions; sensory input, motor
output, and
CNS integration. But, there has been no method for assessing the sensory, motor, and CNS integration function quantitatively, CDP is a tool for assessing the balance function quantitatively under a variety of tasks.
@ES Methods:
@EN To assess the balance using CDP, I studied equilibrium score (ES) of SOT and weight symmetry, latency, and adaptation scores of MCT in 112 Korean healthy population. Arbitarily I divided the population into two groups, under 60 years and over
60
years of age. In SOT, I 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, I studied latencies in sudden translation of foot plate.
@ES Results:
@EN The study group was 112 Korean healthy population with a mean age of 47±26 years. In SOT, the range of median equilibrium scores were from 68 to 93 under 60 years group, 58 to 91 over 60 years group. In MCT, during sudden anterior and
posterior
pertubation, weight symmetries were 101±24.8 under 60 years group and 104±30.1 over 60 years group. Median latencies were 116 to 141msec under 60 years, 127 to 130msec over 60 years. In toes up and toes down test of MCT the mean adaptation
scores
were
50 to 83 and 34 to 75 under 60 years, 64 to 75 and 48 to 73 over 60 years, respectively.
@ES Conclusion:
@EN This study could be a baseline control data in Koreans in assessing the sensory, motor, and CNS integration function of balance in dizziness patient using CDP.
