About

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

Full description

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

30 participants in 2 patient groups

EMG Biofeedback assisted Quadriceps exercises.

Experimental group

Description:

Hot Pack will be applied before session for general relaxation for 10 minutes. Knee isometric exercises will be performed via an EMG Biofeedback device; patients in the EMG BF group will receive visual and auditory feedback.Knee isometrics will be performed with 5 seconds hold. Then, the muscle will be relaxed for 10 seconds and the cycle repeated for a total of 15 minutes. (20 reps, 3 sets) Session will be performed thrice a week for six weeks.

Treatment:

Device: Electromyographic Biofeedback

Quadriceps exercises without EMG Biofeedback

Active Comparator group

Description:

Hot Pack will be applied before session for general relaxation 10 minutes. In the control group, the active electrode will not be connected, so subjects will not receive any feedback from the device. Knee isometrics perform with 5 seconds hold. Then, the muscle will be relaxed for 10 seconds and the cycle repeated for a total of 15 minutes. (20 reps, 3 sets)Session will be performed thrice a week for six weeks.

Treatment:

Other: Quadriceps Isometric exercises
