초록

무릎 슬리브는 재활뿐만 아니라 스포츠 활동 시 손상 예방의 목적으로도 사용되고 있다. 무릎 슬리브의 스포츠 손상 예방을 정의하기 위해서는 고유수용성감각으로부터 기인하는 균형을 평가하는 것이 중요한 요소이다. 본 연구의 목적은 골지 건 기관 자극 패드 무릎 슬리브의 효과를 분석하는 것이다. 5명의 건강한 성인 남성이 본 연구의 실험대상자로 참여하였다. 실험대상자들은 일반 무릎 슬리브와 자극 패드 슬리브를 착용한 상태에서 각각 BIODEX에서 설정된 타겟(Target) 각도를 재연하였고, 한 발 서기 동작을 수행하였다. 각도 재연성 평가의 결과를 보면, 5명의 실험대상자 중 4명의 실험대상자는 무릎 슬리브를 착용했을 때 보다 자극 패드 슬리브 착용 시 %Target angle이 증가하는 결과를 보였다. 한 발 서기 동작 수행 시 무릎 슬리브 착용 시 보다 자극 패드 슬리브 착용 시 유지 시간(duration time)이 증가했으며 x, y 방향에서 COP 길이가 모두 감소했다(COPx - 무릎 슬리브: $162.06{\pm}58.99mm$, 자극 패드 무릎 슬리브: $149.03{\pm}45.30mm$; COPy - 무릎 슬리브: $310.79{\pm}115.89mm$, 자극 패드 무릎 슬리브: $291.57{\pm}76.53mm$). 초기 전이구간, 정적 구간, 말기 전이구간이 차지하는 비율은 무릎 슬리브 착용 시와 자극 패드 무릎 슬리브 착용 시에 유의한 차이를 보였다 (all, p < 0.05). 본 연구의 결과로부터 골지 건 기관 자극 패드 무릎 슬리브 착용이 고유수용성 감각과 균형에 긍정적인 영향을 미치는 것을 확인할 수 있었다.

Knee sleeve has been used for prevention of sport injuries as well as rehabilitation. To investigate prevention of sport injuries of knee sleeve, it is important to evaluate balance associated with proprioception. The aim of this study was to evaluate the effects of a knee sleeve with a pad that stimulate to golgi tendon organ (GTO_PAD) on proprioception and balance ability. Five healthy males were participated for the study. They were asked to reenact target angle with Biodex and perform one leg standing with knee sleeve and knee sleeve with GTO_PAD. There was no significant difference in %Target angle, but the value of %Target angle was higher in subjects wearing knee sleeve with GTO_PAD than only knee sleeve, except for one subject. During one leg standing, time duration was increased in subjects wearing knee sleeve with GTO_PAD. The length of center of pressure in x-axis (COPx) and COP in y-axis (COPy) were decreased when wearing knee sleeve with GTO_PAD (COPx : $162.06{\pm}58.99mm$ in knee sleeve vs. $149.03{\pm}45.30mm$ in knee sleeve with GTO_PAD, COPy : $310.79{\pm}115.89mm$ in knee sleeve, $291.57{\pm}76.53mm$ in knee sleeve with GTO_PAD). There was significant differences in INI_transition, steady, and LAT_transition phase (all, p < 0.05). These findings support that wearing knee sleeve with GTO_PAD might enhance proprioception and balance.
