Abstract

Shoulder joint pain is a very common musculoskeletal disorder, in which about 20 percent of adults experience it more than once in their lives. In this study, an objective assessment was made that subacromial space was increased by pectoralis minor stretching exercise, which has a positive effect on impingement syndrome and shoulder pain. Also, This study examined the effects on pectoralis minor length(PML) and acromio-humeral distance(AHD) following pectoralis minor self-stretching exercise in normal adults. In this study, a total of 30 subjects were recruited and randomly divided into a self-stretching exercise group(n=15) and manual stretching exercise group(n=15) to compare the immediate effects of treatment. Studies have shown that both groups have significantly increased both PML and AHD within the group(p<.05). There was no statistically significant difference in the comparison between the groups(p>.05). The results suggest that self-stretching exercise can be recommended as a treatment method for impingement syndrome and prevention of shoulder disease.

어깨관절 통증은 성인의 약 20% 정도가 일생에 한 번 이상 경험하는 매우 흔한 근골격계 질환이다. 이에 본 연구에서는 작은가슴근 신장운동에 의해 어깨뼈봉우리 밑 공간이 증가하여 충돌증후군 및 어깨통증에 긍정적인 효과가 있다는 객관적 평가를 실시하고, 작은가슴근 자가 신장운동이 도수 신장운동과 비교하여 작은가슴근의 길이와 봉우리 위팔 거리에 미치는 영향을 알아보고자 실시하였다. 경상북도 소재의 대학교에서 성인 남녀 30명을 대상으로 하여 대상자가 스스로 작은가슴근 자가 신장운동을 실시하는 실험군 15명과 치료사에 의해 수행되는 작은가슴근 도수 신장운동을 적용한 대조군 15명으로 두 그룹을 무작위 배치하여 치료의 즉각적인 효과를 비교하였다. 어깨뼈봉우리 위팔 거리를 측정하기 위해 초음파 장비를 사용하였고, 작은가슴근 길이를 측정하기 위해 4번째 늑골과 복장뼈가 만나는 부위 그리고 오훼돌기 아래측면 사이의 거리를 재었다. 연구결과 실험군과 대조군 모두 그룹 내에서 작은가슴근의 길이와 봉우리 위팔 거리 모두 유의하게 증가되었고(p<.05), 그룹 간 비교에서는 통계학적으로 유의한 차이가 나타나지 않았다(p>.05). 이러한 결과는 작은가슴근의 자가 신장운동이 충돌증후군 및 어깨질환의 예방 및 치료에 효율적인 운동방법으로 제시될 수 있다고 사료된다.
