보행 입각기 (stance phase)시 거골하 관절의 운동 특성에 관한 연구

Abstract

The purpose of this study was to analyse the subtalar joint movementcharacteristics in human stance phase. The data of subtalar joint movementpattems are collected by CT A(calcaneus to tibia angle) measurements. CT A isdefined as a angle formed between the bisect of the posterior shank and bisect ofthe posterior heel, as determined by placement of the retroreflective markers. Theangle measured in degrees. The participants are 74 healthy individuals (37 men and37 women) who have no orthopedic and neurological impairment, aged from 19 to29 years(mean 22.95). Prior to participation, each subjecct informed the proceduresof experiment from researcher and assistant researcher. The equipments of this study are walking grid, marking tapes, goniometer, videocamera, monitor and ink for foot print are used in the study. In order to determine the statistical significance of result, the paired t-test andPearson correlation were applied at the 0.05 level of significance. The results were as follows1. The reliability of measured CT A value are showed a high correlation, rangedfrom .86 - .94. 2. The mean value of step width are 7.67cm in men and 6cm in women. So,significant difference between men and women in 0.05 level of significance. 3. There was significant difference between man and women’s TOA(toe outangle)(p<0.05). 4. The CT A of female ’s is more higher than male's one, however not statisticaldifference between man and women(p>0.05). 5. The CT A is reduced according to increasing TOA(p<0.05).
