갑작스런 동요 시 중추신경계는 어떤 판단을 내리는가? | 갑작스런 동요 시 중추신경계는 신체 흔들림을 최소화하고 기저면 내 무게중심을 유지하기 위해 비수의적 반사기전을 통해 균형을 회복하고자 한다.12 이 과정에서 인체 중심부의 체간 근육(core muscles)이 중요한 역할을 하며,13,14 그 중에서도 복부 근육은 체간 안정화에 역학적인 기여가 높은 것이 밝혀지면서 많은 임상가들의 주목을 받아왔다. | |
복부 근육은 무엇으로 분류되는가? | 12 이 과정에서 인체 중심부의 체간 근육(core muscles)이 중요한 역할을 하며,13,14 그 중에서도 복부 근육은 체간 안정화에 역학적인 기여가 높은 것이 밝혀지면서 많은 임상가들의 주목을 받아왔다.15-17 복부 근육은 수축 패턴에 따라 복부 심부근의 독립 수축을 유도하는 할로잉(hollowing)과 모든 복부근육을 동시 수축하는 브레이싱(bracing)으로 분류된다. 따라서 안정시의 균형능력 비교 뿐 만 아니라 균형회복에 중요한 역할을 하는 복부수축의 패턴에 따른 차이가 있는가를 함께 확인할 필요하다. | |
균형회복 능력의 분석을 위해 표식자를 신체의 어느곳에 부착하였는가? | 피험자의 신체 분절을 인식하기 위하여 Modified Helen hays marker set에 따라 해부학적 경계점에 부착하였다.18 총 20개의 표식자를 목뼈 7번 가시돌기. 등뼈 7번 가시돌기, 등뼈 12번 가시돌기, 엉치뼈 1번 가시돌기, 전상장골극 양측, 후상장골극 양측에 부착하였으며 지지면 이동 장비의 움직임을 캡쳐하기 위하여 위에 4개의 표식자를 부착하였다. 갑작스런 동요 시 균형 회복 능력을 평가하기 위하여 척추 분절의 각 변위와 무게중심점의 선형 변위를 분석하였고 모델링 방법은 다음과 같다. |
