초록

본 연구의 목적은 해부학적 근거로 제작한 5가지의 EMS 요추 복압 벨트가 요추 안정화에 미치는 영향을 연구하는 것이다. 본 연구는 요방형근, 척추세움근, 내복사근, 외복사근, 대요근으로 총 5가지의 코어 근육을 선정하여 이에 맞는 근육 모양과 통증 유발점인 압통점을 고려해 전도성 원단으로 패턴을 설계하여 복압 벨트에 결합했다. 총 4가지 동작으로 실험을 진행하여 각각 다른 EMS복압 벨트가 요추 안정화에 미치는 영향을 알아보았다. 건강한 신체의 20대 남성 5명을 대상으로 진행하였고 선정 조건은 최근 3개월 동안 요통 과거력이 없고 사전 검사를 통해 제한되는 동작이 없고, 체간의 근력이 정상등급에 속한 대상이다. 실험 동작의 순서는 하지직거상 검사, 좌전굴, 체전굴, 배근력으로 다음 동작에 제한되지 않게 선정하였다. 동작 간의 휴식은 2분으로 진행하였고, EMS복압 벨트를 착용 후 실험을 진행할 때는 혈류량 증가와 근 활성화를 위해 전기자극을 10분씩 적용하고 진행하였다. 실험 결과의 통계는 비모수 검정으로 윌콕슨 검정과 프리드만 검정을 실시함으로 구체적인 차이를 분석하였다. 본 연구의 결과 5가지의 패턴 중 5,4,3,1,2 순으로 Type별 순위 결과를 확인할 수 있었으며 각 근육의 움직임과 연관성이 있는 실험 동작에 조금 더 유의미한 결과를 확인할 수 있었다. 본 연구의 결론은 해부학적 근거로 제작된 패턴으로 인해 각 근육에 각기 다른 모양으로 전기자극을 전달하였을 때 구분되는 효과를 확인할 수 있었으며 일반인 대상으로 일상생활이나 트레이닝에 있어 요추 안정화를 향상할 수 있을 것으로 기대된다.

In this study, we investigated the effects of five EMS lumbar back pressure belts produced on an anatomical basis on lumbar spine stabilization. Five core muscles were selected, including the urinal, vertebral column, endotracheal, external abdominal, and large back muscles, and patterns were designed using a conductive fabric considering the appropriate muscle shape and pain-causing points. We experimented with four motions to examine the effects of different EMS abdominal compression belts on lumbar spine stabilization. Five healthy men in their 20s were selected. The selection conditions include no back pain history for the past three months, no restricted movements through pre-inspection, and the muscular strength of the body should belong to the normal grade. Using SLR, the sequence of experimental actions was chosen from the following but not limited to left-hand, body-hand, and back-line forces. Resting between movements lasted for 2 min, and the experiments were conducted after wearing the EMS abdominal pressure belt. Electrical stimulation was applied for 10 min to increase blood flow and muscle activation. The statistics of the experimental results were analyzed for specific differences by conducting the Wilcoxon and Friedman tests with nonparametric tests. The ranking results of each pattern were successfully assessed in the order of 5, 4, 3, 1, 2 for the five patterns, and we could identify slightly more significant results for experimental behavior associated with each muscle movement. Patterns produced based on anatomy showed differentiated effects when electric stimulation was applied to each muscle in different shapes, which could improve the stabilization of the lumbar spine in everyday life or training to the public. Based on these results, subsequent research would focus on developing smart healthcare clothing that is practical in daily life by employing different anatomical mechanisms, depending on the back pain, to utilize trunk-type tights.
