Abstract
One of the most important problems of knee arthroplasty operations is the speed of rehabilitation in patients. The object of this study wase to analyze the progressive resistance exercises (PRE) with knee flex device and its effect in increasing muscular power and specially decreasing the angle of ROM in people who had Arthroplasty operation.
This study was to Quasi – experimental and has done on 30 voluntary male patients between 55–60 who had knee arthroplasty. These patients were randomly divided in 2 groups of control and experimental each with 15 samples and then completed standard questionnaire (oxford score knee) and described their physical situation, and their life after knee arthroplasty. In the first evaluation to register the knee ROM and determine the power of Quadriceps femoris muscle, the digital set square and dynamometer device were used. To measure their pain we used the Visual Analogue Scale (VAS). The experimental group in 8 weeks and 3 sessions per week were done exercise with different degrees of knee flex device and at the end data were collect in both groups and analyzed by descriptive and dependent – independent (t) test .
The results showed that working with knee flex device and doing progressive resistance exercises is meaningful in decreasing the angle of knee and increasing power and decreasing the muscle pain in experimental group p<0.05
Doing resistant exercises with knee flex device decreases the knee flexion angle, increases the power of Quadriceps femoris muscle and also decreases the pain of knee in people who had knee arthroplasty
