슬관절 골관절염 환자에서 근육내 자극요법의 치료 효과
Osteoarthritis(OA) has become one of the most important medical problem among the old age because it causes severe functional disability, but, up to date, the therapeutic methods for OA have not been so satisfactory to the patients with OA. Authors have investigated the effectiveness of intramuscular stimulation(IMS) therapy as an substitutive therapy for the relief of pain and dysfunction in patients with OA of the knee.
Eighteen patients who had visited the department of family medicine, Korea university anam hospital, with symptomatic OA of the knee during the period from March 1 to May 31. 2001 were included in this study and treated with IMS therapy on the quadriceps and hamstring muscles four times during two weeks. Patients self-scored Korean Western Ontario and McMaster universities Osteoarthritis Index (KWOMAC) at baseline and after the last therapy. The result was analysed by paired t-test and ANOVA. RESULT: Patients improved on KWOMAC scales for pain, stiffness, function and total scores after IMS therapy(p<0.05). The demographic characteristics such as body mass index (BML), duration of disease, affected site, radiologic finding did not have influence on the result of this study. No adverse effects of IMS therapy were reported.
In this study, the improvement of pain, stiffness, and function of knee joint after treatment was reported. This study suggest that IMS is an effective and safe substitutive therapy for patients with OA of Knee.
