The Effect Of Dynamic Versus Isometric Resistance Training With Swd On Pain And Functioning Among Adults With Osteoarthritis Of The Knee

Abstract

In this study we compare 4 weeks of isometric versus dynamic resistance training with SWD ON pain and functioning among adults with osteoarthritis of the knee. A total of 30 volunteer subjects with OA of the knee, Group A: (Dynamic resistance training with shortwave diathermy) -n = 15 (7 males and 8 females) and Group B: (Isometric resistance training with shortwave diathermy) -n = 15 (8 males and 7 females). Strength exercises for the legs, 3 times weekly for 4 weeks. Dynamic group: exercises across a functional range of motion; isometric: exercises at discrete joint angles. The time to descend and ascend a flight of stairs and to get down and up off of the floor. Knee pain was assessed immediately after each functional task. The VAS, WOMAC and Stair Ascending and descending score Index was used to assess perceived pain, stiffness, and functional ability. Measures of pain and functioning were significantly and favourably affected in the training groups. The improvements in the 2 training groups as a result of their respective therapies were not significantly different. Dynamic or isometric resistance training with SWD improves functional ability and reduces knee joint pain of patients with knee OA.
