The purpose of this study was to identify the effect of transcutaneous electrical nerve stimulation(TENS) and electroacupuncture(EA) after sciatic nerve crush injury in rats. Subjects were classified TENS group with TENS application, EA group with EA application and Control group which is not applic...

말초신경은 무엇에 의해 손상받기 쉬운가? | 말초신경은 압좌(crush), 압박(compression), 신장(stretching), 결출(avulsion)에 의해 손상받기 쉽고 이로 인하여 피부나 근육에서부터 척수와 후근절 수준에까지 각각의 신경세포와 비신경세포에 심각한 손상을 초래한다[1]. 최신 치료기법과 재건술에도 불구하고 손상 수준, 탈신경된 기간, 손상된 신경섬유의 형태, 직경 및 연령 등 다양한 변수로 인하여 말초신경의 형태학적․기능적 재생은 완전하지 않다[2]. | |
말초신경 손상은 어떤 상태를 초래하는가? | 최신 치료기법과 재건술에도 불구하고 손상 수준, 탈신경된 기간, 손상된 신경섬유의 형태, 직경 및 연령 등 다양한 변수로 인하여 말초신경의 형태학적․기능적 재생은 완전하지 않다[2]. 말초신경 손상은 치료 후에도 운동신경과 감각신경세포의 감소, 느리고 불충분한 축삭 생성, 중추신경계의 지속적인 변화와 신경병변성 통증인 이질통증(allodynia)과 통각과민(hyperalgesia) 등을 초래하게 된다[1][3]. | |
흰쥐를 대상으로 좌골신경 압좌 손상 유발 후 경피신경전기자극과 전침자극을 적용하고 진통효과와 기능회복에 미치는 영향을 알아본 결과는 어떠한가? | 실험동물은 경피신경전기자극군을 적용한 TENS군, 전침자극군을 적용한 EA군과 대조군으로 구분하였고, 각각의 군은 전기자극 적용기간에 따라 1일군, 7일군 및 14일군으로 나누었다. 경피신경자극과 전침자극을 적용한 결과, 실험군에서 대조군에 비하여 통각신경활성의 지표로 이용되는 c-fos 발현의 감소, 발도피지연시의 증가, 좌골신경기능지수의 증가를 통해 전기자극이 말초신경 손상에서 통증억제와 기능회복을 증가시키는 것으로 나타났다. 하지만 경피신경전기자극군과 전침자극군간의 유의한 차이는 관찰되지 않았다. |
