To Evaluate the Effectiveness of Isotonic Quadriceps Resistance Training on Selective Functional Activities and Pain in Patient with Osteoarthrosis of Knee

Objective: To evaluate the effectiveness of isotonic quadriceps resistance training on selective functional activities and pain in patient with osteoarthrosis of knee.

Methods: Thirty patients with unilateral osteoarthrosis of knee, were randomly assigned in two groups. (Control N=15, Experimental N=15). The patient in the both groups were underwent wax therapy for 20 minutes by using clothing method in a day. The control group underwent isometric quadriceps muscle setting exercise for a period of 10 minutes, with a brief rest in between. The experimental group underwent of pain tolerable isotonic quadriceps muscle resisted exercise by using quadriceps chair for a period of 10 minutes, with a brief rest in between.

Outcome measures: Functional capacity and pain during rest were tested before and after training in both the groups by using, NPRS (Numerical Pain Rating Scale) and WOMAC SCALE (Western Ontario and McMaster university osteoarthritis index).

Results: The isometric training group scored a NPRS pain rating scale mean value of 1.87 ± 0.64 and isotonic resisted training shows a mean value of 2.67 ± 0.99 with a t value of 4.598 and a significant of p value 0.001. Also, the study revealed that the patient who received isometric training shows a WOMAC score mean difference of 9.28 ± 7.07 and isotonic resisted training shows a value of mean difference of 18.90 ± 8.07 with a t value of 3.474 and a significant of p value of 0.002. This shows that the isotonic resistance training and wax bath was highly effective in improving functional activity and reducing pain in patient with OA knee.

Conclusion: Both the training group showed a marked decrease in pain scores and increase in functional activities. When compared between the groups, the isotonic training group had a significant improvement in functional activities and pain reduction in patient with OA knee.
