Abstract

Joint flexibility is an important factor which affect the process and duration of the therapeutic methods in the filed of occupational therapy. Hip joint flexibility and electromyography (EMG) of major flexor and extensor for the hip joint were examined to understand the biomechanical characteristics of Proprioceptive Neuromuscular Facilitation (PNF). Hip joint flexibility increased $18.9^{\circ}$ on average after PNF was performed by a designated assistant on 10 college students. EMGs of quadriceps femoris muscle and hamstring muscles agreed with biomechanical characteristics of proprioceptive organs in muscles.

작업치료에서 관절의 가동성은 치료 절차와 기간에 영향을 미치는 중요한 요소이다. 수동적 스트레칭과 능동적 스트레칭을 병행하는 고유수용성 신경근 촉진법이 고관절의 가동성에 미치는 영향과 주요 굽힘/폄근의 근전도 활성정도 바탕으로 고유수용성 신경근 촉진 스트레칭의 생체역학적 특징을 고찰하였다. 10명의 20대 학생을 대상으로 고유수용성 신경근 촉진 스트레칭을 실시한 결과 고관절의 가동성이 전담 보조자의 도움을 받았을 때, 평균 $18.9^{\circ}$ 증가하였고 넙다리네갈래근과 뒤넙다리근의 근전도의 활성 또한 고유수용기의 생체역학적 특징을 나타내었다.
