관절제한이 정적직립자세에 미치는 영향

초록

The purpose of this study was to investigated into the displacement of COM and COP, CV(displacement of COM and COP) during quiet standing posture on constraint of joint. Nine subjects were participated in the experiment(age: 24.50±2.57 yrs, height: 177.50±2.93 cm, weight: 68.33±5.19 kg). There are four condition of joint constraints using splint and compression bandage(no constraint, constraint of knee, constraint of hip, constraint of trunk). The study method adopted 3D analysis with six cameras and ground reaction force with two force-plates. The results were as follows; In displacement of COM, CH and CT showed larger forward displacement of COM in AP direction. NC, CK, and CT was larger in order of the forward displacement of COM in ML direction, and CH were larger forward displacement of COM than CT. In trajectories of COP, NC, CK and CT showed larger forward trajectories of COP in right foot. In CV of COM, there was larger CV during CT in ML direction. In all of condition, AP direction of the CV was higher than the ML direction of the CV. In CV of COP, there was larger CV druing CH and CT in AP and ML direction of right foot, and there was larger CV during CT in AP direction of both foot. In all of condition, AP direction of the CV was higher than the ML direction of the CV.
