초록
무릎 과다 폄을 가진 대상자에게 비대칭적 선 자세와 같은 외부적 요소가 추가되게 되면 무릎 관절에 가해지는 체중 지지가 더 증가하게 되며, 무릎 뒤쪽 구조들의 과신장이 유발된다. 이는 무릎 과다 폄 변형을 증가시킬 뿐만 아니라, 앞 십자인대와 같은 무릎 주변 연부조직의 변형 및 손상을 유발하는 요인이 될 수 있다. 따라서, 비대칭적 선 자세가 무릎 관절의 위치와 하지 근육의 활성도에 어떠한 영향을 미치는지 알아보는 것이 이 연구의 목적이다. 33명의 자발적 참여대상자들이 연구에 참여하였으며 총 60개의 다리에 대하여 무릎 과다 폄군, 정상군으로 나누어 하지근육의 근 활성도 및 무릎 폄 각도를 측정하였다. 비대칭적 선 자세 시, 무릎 관절 폄 각도와 장딴지근의 근 활성도 값은 정상군과 무릎 과다 폄 군 사이의 통계학적 유의한 차이가 나타났다. 결과를 토대로 비대칭적인 선 자세가 무릎의 과다 폄을 증가시키는 요인이 됨을 확인하였다. 따라서, 무릎 정렬에 이상을 가진 대상자들에게는 정상적인 정렬 회복과 함께 대칭적인 선 자세를 유지할 수 있도록 하는 치료적 중재 수립에 도움을 줄 것이며, 추후 엉덩관절과 발목관절의 영향을 포함한 조사연구가 필요하겠다.
Abstract
The purpose of this study was to investigate the effect of hyper-extended knee and asymmetric standing posture on knee joint position and lower extremity muscle activity. Thirty-three voluntary participants participated and included sixty legs in the study. The sixty legs were divided into two groups: hyper-extended knee and normal group. The muscle activity and knee extension angle were measured. In the asymmetric standing posture, the knee joint extension angle and the muscle activity of the gastrocnemius were statistically significant between the normal group and the hyper-extended knee group. Based on the results, we confirmed that the asymmetric standing posture increases the hyper-extended knee. Therefore, it will contribute to the establishment of therapeutic guide for the subjects with hyper-extended knee to maintain the symmetrical standing posture, and future studies need to be conducted including the effects of the hip joint and ankle joints.
