Electromyographic Biofeedback on Performance of Vastus Medialis Oblique Muscle in Knee Osteoarthritis

Effects of Electromyographic Biofeedback on Performance of Vastus Medialis Oblique Muscle in Knee Osteoarthritis

This study intends to determine the Effects of Electromyographic biofeedback on performance of vastus medialis oblique muscle in knee osteoarthritis.

This is a single blinded randomized controlled trial, will be conducted at Railway General Hospital.Rawalpindi.

(EMG) biofeedback as an adjunct therapy to standard exercise regime for increasing muscle strength ,this study is planned to determine the effects of electromyographic biofeedback on performance and thickness of vastus medialis oblique muscle, knee pain and on lower extremity function in patients with Knee Osteoarthritis. The sample size was calculated to be n=34 through Open Epi tool version 3, with 95 % confidence interval (CI), and power 80%.

After the completion of therapeutic protocols, the participants will be assessed with the help of Numeric Pain Rating Scale (NPRS), WOMAC, Lequesne questionnaire , 1 Repetition maximum( RM) and with MSK ultrasound
