Abstract

The purpose of this study was to investigate the functional changes of the vastus medialis while the neuromuscular electrical stimulation(NMES) was performed in elderly women with knee osteoarthritis. The subjects of this study were 30 women who were diagnosed degenerative arthritis, 15 in the experimental group and 15 in the control group. The experimental group performed conventional physical therapy and neuromuscular electrical stimulation, and the control group received only conventional physical therapy, five times per week for four weeks. Outcome measures were assessed before and after 4weeks using the VAS(pain), quadriceps femoris strength, thigh circumference, and Q-angle. The data of the quadriceps femoris strength and thigh circumference were significantly increased in experimental group(p<0.05). The data the pain was significantly decreased in both the two groups(p<0.05). There were statistically significant differences in quadriceps femoris strength and thigh circumference between the two groups(p<0.05). As the result, the application of neuromuscular electrical stimulation of the vastus medialis could be more effective for decrease pain and improving muscle function in patients with knee osteoarthritis.

본 연구의 목적은 퇴행성 슬관절염 환자의 신경근전기자극의 적용이 내측광근의 기능적 변화에 미치는 영향을 알아보기 위해서이다. 퇴행성 슬관절염으로 진단받은 여성 30명을 대상으로 보존적 물리치료를 적용한 대조군 15명과 신경근전기자극치료를 병행한 실험군 15명을 임의 배치하여 주 5회, 총 4주간의 치료후, 실험 전 후의 통증, 대퇴사두근력, 대퇴둘레, 그리고 대퇴각도의 변화를 측정하였다. 실험군에서 대퇴사두근력과 대퇴둘레를 측정한 결과 유의한 증가를 나타내었고, 통증의 측정결과에서는 실험군과 대조군 모두 유의한 감소를 나타내었다. 군 간의 비교에서는 대퇴사두근력과 대퇴둘레에서 유의한 차이가 나타났다. 결과적으로 신경근전기자극을 이용한 내측광근의 선택적 강화가 슬관절염 환자의 통증 감소 및 슬관절의 근 기능을 향상시키는데 효과가 있었음을 확인할 수 있었다.
