시ㆍ촉각 되먹임이 넙다리네갈래근 등척성 운동에 미치는 영향 = The Effects of Visual and Tactile Feedback on Quadriceps Isometric Exercise

다국어 초록 (Multilingual Abstract)

Physical therapists have been using biofeedback training to induce improvements in various circumstances. The purpose of this study was to compare the effects of virtual and tactile feedback using electrical stimulation on quadriceps strength. Nineteen women without known impairment of the neuromusculoskeletal system volunteered for this study. Subjects were randomly allocated into three groups: visual feedback, tactile feedback, and control group. The torque of isometric knee extension force was measured. Subjects were asked to exert the maximal isometric contraction force of quadriceps over a 30 second period. The resting period of 10 minutes was given after the maximal isometric contraction to avoid the muscle fatigue. In between groups comparison, significant differences of the peak torque and the torque area were found on the performance of the maximal isometric contraction of quadriceps (p<.05). The values peak of torque and torque area were significantly higher during visual feedback than tactile feedback. The results of this study suggest that visual feedback is more powerful than tactile feedback (p<.01).
