Abstract

The purpose of this study was to investigate the effects of cervical vertebral height and shoulder stabilization on anterior head posture in people with turtle neck. The subjects of this study consisted of normal and healthy people with 30 turtle necks. Subjects were randomly assigned to shoulder stabilization exercise and cervical vertebrae exercise (30 men, 15 men and 15 women, height: $168.67{\pm}6.51$, $22.33{\pm}8.27$, $65.03{\pm}11.98$, and $28.66{\pm}1.91$), In the experimental group, shoulder stabilization exercise and cervical spine exercise were performed for 4 weeks. Deep neck flexor, leavator scapular, upper trapezius, rhomboid, and lower trapezius showed significant differences in shoulder stabilization and cervical vertebrae before and after the experiment. As a result, the CVA value decreased significantly and the muscle activity value increased significantly when exercise and Mckenzie program were applied. These results show that exercise and Mckenzie programs have a positive effect on turtle neck improvement.

본 연구의 목적은 거북목을 가진 사람에게 메켄지 폄운동과 어깨안정화운동이 앞쪽머리자세에 미치는 영향에 대해 알아보는 것이다. 연구대상자는 30명의 거북목을 가진 평범하고 건강한 사람들로 이루어져 있다. 대상자는 어깨안정화운동과 메켄지 폄운동으로 나누어(인원=30, 남자 15명, 여자 15명) 무작위로 나누어 6주 동안 실시되었다. 본 연구는 마름근, 아래등세모근의 운동프로그램과 깊은목굽힘근, 위등세모근, 어깨올림근의 신장프로그램을 통한 목뼈의 머리척추각(Cervical Vertebra Angle) 값과 각 근육별 근전도의 차이를 알아보았다. 앞쪽머리자세와 경우에는 목과 등근육의 활성도가 감소하고 피로도는 증가함을 보였다. 이러한 결과는 목과 머리의 불안정한 상태를 안정시키기 위해서는 위등세모근, 깊은목굽힘근, 어깨올림근의 신장과 마름근, 아래등세모근의 운동을 통해 거북목의 개선에 긍정적인 변화를 줄 것으로 보인다. 이러한 근육들의 불균형한 수축과 과도한 긴장으로 근육의 경직과 피로가 누적되며 이러한 상태가 계속 유지되게 되면 만성화상태가 되어 근육의 불균형으로 인해 통증을 유발할 수 있으며, 피로의 누적으로 인하여 자극에 대한 반응과 근력을 약화시켜서 목 디스크가 발생할 확률이 높아질 것으로 사료된다.
