Methods： A total of 90 cases with KOA were randomized into an observation group and a control group, 45 in each group. Those in the observation group conducted Yi Jin Jing exercise once a day; whereas those in the control group received no therapies at all. The therapeutic effects have been assessed after 8 weeks of observation. Results： After 8 weeks of observation, the isokinetic muscle strength of quadriceps femoris muscle in the treatment group was substantially improved, whereas there were no distinct changes of isokinetic muscle strength of quadriceps femoris muscle in the control group. Conclusion： Yi Jin Jing exercise can definitely improve the quadriceps femoris muscle strength of patients with KOA. It is therefore an effective intervention method for KOA.展开更多

Methods： Totally 30 KOA patients were enrolled and treated mainly with massaging quadriceps, 20 min for each session, once a day, 2 weeks as a treatment course, and for 2 courses in total. After treatment, the changes of visual analogue scale （VAS） and Western Ontario and McMaster Universities osteoarthritis index （WOMAC） were observed. Result： The VAS and WOMAC scores dropped after treatment, with a statistically significant difference （P〈0.01）. After a course of treatment, the recovery rate was 33.3% and the total effective rate was 86.7%; after 2 courses, the recovery rate was 60.0% and the total effect rate was 96.7%. Conclusion： Massaging quadriceps can alleviate pain, improve the function of knee joint, and produce a significant short-term efficacy in treating KOA.展开更多
