체위에 따른 균형 안정성 한계의 비교

Abstract

The purposes of this study were to evaluate and compare the limits of stability(LOS) atdifferent body positioning(standing and one leg standing) in normal 20 years of age. Fourty subjects participated in the study. Subjects comprised 20 males and 20 femaleswho without neurologic. orthopaedic impairments and balance performance impaired. TheLOS was measured at Two Feet Forceplate and One Leg Forceplate with BPM(BalancePerformance Monitor) Dataprint Software Version 5.3. the subjects stood 4 inchesbetween the feet at Two Feet Forceplate and stood one legged at One Leg Forceplate. Inthis study applied the paired t-test and independent t-test to determine the statisticalsignificance of results at 0.01 and 0.05 level of significance. The results of this studywere as follows: 1) the anteroposterior LOS significantly increased with one leggedstance(p(0.05). 2) The mediolateral LOS significantly decreased with one leggedstance(p(O.Ol). 3) There were significant difference posterior LOS in standing andanterior LOS in one legged stance according to sexual ditference(p(O.05). 4) the mediolateral LOS was not significant difference between standing and one legged stanceaccording to sexual difference(p)0.05) ‘
