Brief Summary

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

Conditions

Knee Osteoarthritis

Outcome Measures

Primary Outcomes (3)

• Numeric Pain Rating Scale (NPRS)

  Changes from the baseline, Numeric Pain Rating Scale (NPRS) is used to assess pain. It scores ranges from 0-10, 0 means No pain and 10 means Severe pain. Patient will be asked to verbally report the pain score.

  Post 6 Weeks

• 1 Repetition Maximum

  Changes from the baseline, 1 RM Is used to assess maximum muscle strength. Patient is asked to extend knee against maximum resistance once.

  Post 6th week

• Vastus medialis Oblique(VMO) Thickness

  Changes from the Baseline, Musculoskeletal ultrasound will be used to measure maximum thickness of VMO muscle. Assessment will be done by a Consultant radiologist using a 7-12 MHz probe

  Post 6th week

Secondary Outcomes (1)

• Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)

  Post 6 weeks

Study Arms (2)

EMG Biofeedback assisted Quadriceps exercises.

EXPERIMENTAL

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.

Device: Electromyographic Biofeedback

Quadriceps exercises without EMG Biofeedback

ACTIVE COMPARATOR

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.

Other: Quadriceps Isometric exercises

Interventions

Electromyographic Biofeedback DEVICE

Surface EMG biofeedback is an adjunct therapy to standard exercise regime for increasing muscle strength .Electromyographic (EMG) biofeedback is a specific form of biofeedback. The biofeedback device records muscle activity through the application of electrodes superficially or subcutaneously when targeting specific muscles

EMG Biofeedback assisted Quadriceps exercises.

Quadriceps Isometric exercises OTHER

In supine lying or sitting, Patient is asked to press down knee while contracting Quadriceps muscles.

Quadriceps exercises without EMG Biofeedback
