Effect of exercises for VMO in patients with OA Knee by EMG analysis: Quasi experimental Study

Abstract

Osteoarthritis is a chronic degenerative disorder primarily affecting the articular cartilage of synovial joints, with eventual bony remodelling and overgrowth at the marginal of the joints. Electromyography is used to evaluate the scope of neuromuscular disease or trauma, and kinesiological electromyography is a tool to study muscle function. The Vastus Medialis Oblique is the most important quadriceps muscle and the most responsible muscle for knee stability.

Aim: To check the EMG activity of Vastus Medialis muscle before and after multi model exercises for Vastus Medialis muscle in patients with OA knee.

Method: Total 40 subjects (15 male and 25female) were taken in this study. EMG activity of VMO was recorded before and after exercises.

Outcome Measure: EMG activity-Amplitude

                                  NPRS - Pain scale

Statistical Analysis: The differences between the Vastus Medialis Oblique muscle was assessed by using student t-test.

Results: The EMG activity of Vastus Medialis muscle was recorded

Conclusion: These finding suggest that there was significant difference in data before and after intervention.
