가상현실에서 시각적 피드백 유,무에 따른 고관절 운동 동작 오차 수준 비교

The purpose of this study was to know that the effects of with and without visual feedback affects adult`s movement of the hip joint in three dimensional axis on virtual reality. Eight health adults participated and performed three exercise contained that one leg abducted under the condition with visual feedback of their movements and with non-visual feedback. The angle of hip abduction were analyzed in three dimensional axis (Rx, Ry, Rz), and errors of the angles among the subjects were compared followed by with and without visual feedback. The visual feedback were able to more precise movements in Rx axis (p=.034) and Ry axis (p=.008) than non-visual feedback. The exercise with visual feedback can produce positive effect on exact movements during exercise in environment of virtual reality. We expect to adopt rehabilitation treatments and learning of exercise motion for increase of its interest
