전방머리자세를 가진 성인들에게 목 돌림 수행 시 시각적 생체되먹임 적용이 목의 가쪽 굽힘 움직임 패턴과 목빗근 근활성도에 미치는 영향 = Effects of Visual Biofeedback on Movement Patterns of Neck Lateral Bending and Muscle Activation of Sternocleidomastoid During Neck Rotation in Adults with Forward Head Posture

다국어 초록 (Multilingual Abstract)

PURPOSE: The purpose of this study was to investigate that the differences in sternocleidomastoid muscle activity, neck rotation angle, neck lateral bending angle and neck lateral bending onset time between conditions with and without visual biofeedback during neck rotation. METHODS: Ten male and four female adults with condition of forward head posture were recruited in this study. Subjects conducted to left and right maximal neck rotation under the conditions with and without visual biofeedback. During neck rotation, kinematic data of neck rotation, neck lateral bending movement, and electromyography activities of bilateral sternocleidomastold muscles were collected. Differences in dependent variables between conditions with and without visual biofeedback were analyzed using paired t-test. RESULTS: There were significant decreases in lateral bending angle, while lateral bending movement onset time was delayed significantly when applying visual biofeedback (p<.05). However, there were no significant differences in the activation of left and right sternocleidomastoid muscles and neck rotation angle between conditions with and without visual biofeedback (p>.05). CONCLUSION: These findings suggest that visual biofeedback may be effective for axial rotation of cervical spine during neck rotation in adults with forward head posture.
