Effect of Resisted Multi Angle Isometric Exercises vs Resistance Band Exercises on Pain, Muscle Strength and Functional Activities Among Subjects With Patellofemoral Osteoarthritis of the Knee

Background: Patellofemoral osteoarthritis (PFOA) is a degenerative knee condition that affects the articulation between the femur and patella, leading to anterior knee pain, stiffness, and functional limitation. OBJECTIVE: To compare the effects of resisted multi-angle isometric exercises versus resistance band exercises on pain, functional activities, and quadriceps muscle strength in individuals with patellofemoral osteoarthritis, using the KOOS questionnaire and Biodex assessment. A total of 30 participants aged 40–60 years wit Methods: h clinically diagnosed PFOA were recruited and randomly divided into two groups. Group A received resisted multi-angle isometric exercises with pulsed shortwave diathermy (PSWD), while Group B received resistance band exercises with PSWD. Both groups underwent treatment for three weeks. Baseline and postintervention outcomes were measured for pain, function (as assessed by the KOOS), and quadriceps strength (using the Biodex). Both Results: groups showed statistically signicant improvements in pain, functional outcomes, and quadriceps strength (p < 0.05).Group A demonstrated signicantly greater improvements than Group B in pain reduction (KOOS: 75.80 vs. 60.38, p = 0.011), functional activity (KOOS: 76.38 vs. 56.68, p = 0.002), and quadriceps strength at 0° exion (34.15 vs. 26.84, p = 0.001). However, no signicant differences were observed between the groups at 30° exion (57.76 vs. 54.08, p = 0.253) and 60° exion (128.49 vs. 122.61, p = 0.445). Re CONCLUSION: sisted multi-angle isometric exercises are more effective than resistance band exercises training in reducing pain, enhancing functional activities, and improving quadriceps strength among individuals with patellofemoral osteoarthritis.
