Functional Exercise Comparison Of Primary Osteoarthritis And Rheumatoid Arthritis With Osteoarthritis

Objective: The aim of this study is to compare the effect of the quadriceps musculature functional exercise on the rehabilitation of patients with different causes of knee osteoarthritis.Patients with knee osteoarthritis and patients with rheumatoid arthritis plus osteoarthritis have the short-term isometric quadriceps femoris contraction exercises,we observe the effect of this form of exercise in reducing pain and joint stiffness and improving the therapeutic effect of joint function, and we compare the differences of effects between the two diseases. We suppose to provide an economic, convenient and effective treatment for patients with knee osteoarthritis, and provide a reference for the comprehensive treatment of rheumatoid arthritis patients with knee osteoarthritis.Methods: Patients were selected the department of rheumatism and Orthopaedics clinic,who had KOA and KOA with RA(the condition is stable for more than 3 months, low or moderate disease activity,DAS28-ESR<5.1), which full the diagnosis standard of KOA and RA. The OA group and RA+OA group were divided into two subgroups according to the random number table, and randomly divided into rehabilitation group and control group. All patients avoided heavy manual labor and mountain climbing and other activities during the experiments. Patients with RA receive primary drug therapy.Therapeutic group: The patients received four tipes of quadriceps isometric isotonic contraction(squat down against the wall, Clinostatism tight the legs, extending the knee and resistance resistance,supine position and lift the leg) for three months.Crntrol group: Two groups of patients maintained the state before the experiment.All the patients avoided loading and climbing during the experiment. At the end of the experiment, the experimental results were compared by the knee pain VAS score and WOMAC score before and after the experiment.Result: The results show that of VAS score, WOAMC pain, stiffness, joint function score and WOMAC total score of the patients with the primary knee osteoarthritis(therapeutic group and control group) have significant statistical significance(P < 0.01).The VAS score, WOAMC pain, stiffness, joint function score and WOMAC total score of the patients with the knee and RA(therapeutic group and control group) have significant statistical significance(P < 0.01).The differences of VAS score and WOMAC joint function score of the patients with original KOA and KOA with RA in the therapeutic group are very significant(P < 0.01).But there was no significant(P > 0.05) in the differences of WOMAC pain, stiffness, and overall WOMAC scores between the two groups.Conclusion: Quadriceps isometric isotonic contraction can improve knee joint function of the patients who have primary KOA and KOA with RA. The effect of this fuctional exercise for the simple knee osteoarthritis patients is better than that for rheumatoid arthritis patients.
