Abstract

The purpose of this study was to investigate the influence of different sitting postures on range of motion, strength and proprioceptive sense of neck. Fifteen healthy university students participated in the study. Depending on upright sitting position and slump sitting position, range of motion and joint position sense were measured by using Dualer IQ. Also, the maximum isometric strength and force sense were measured by using linear force. As a result, we found that the maximum angle of neck extension and the maximum isometric strength at flexion were significantly higher in upright posture than in slump posture. Also, the maximum angle of neck flexion and the maximum isometric strength at extension were higher in slump posture than in upright posture. According to the result, proper proprioception can have an beneficial effect on postural revision of neck and body by providing the information that cognize the position of head through and sustain upright posture.

본 연구의 목적은 다른 앉기 자세에 따라 목의 관절가동범위, 근력, 위치감각과 힘 감각에 어떠한 영향을 미치는가에 대해 알아보고자 하였다. 본 연구는 15명의 건강한 일반 대학생이 참여하였다. 곧은 앉기 자세와 구부정한 앉기 자세에 따라 관절가동범위와 관절위치감각은 관절각도 측정기를 사용하여 측정하였고, 최대 등척성 근력과 힘감각은 linear force를 사용하여 측정하였다. 그 결과 곧은 자세가 구부정한 자세보다 목의 최대 신전각도, 굴곡시 최대 등척성 근력이 유의하게 컸다(p<0.05). 또한 곧은 자세에서 관절위치감각과 힘감각의 오차가 유의하게 작았다(p<0.05). 이와같은 결과를 통해 다른 앉기자세가 목의 움직임 범위와 근력, 고유수용성감각에 영향을 미치며 곧은 앉기 자세가 구부정한 자세보다 관절가동범위와 근력에 이점이 있으며 고유수용성감각에 대한 인지능력이 향상됨을 알 수 있었다.
