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.

Study Overview

Detailed 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

Design Details

  • Primary Purpose: TREATMENT
  • Allocation: RANDOMIZED
  • Interventional Model: PARALLEL
  • Masking: SINGLE

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: EMG Biofeedback assisted Quadriceps exercises.
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.
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
ACTIVE_COMPARATOR: Quadriceps exercises without EMG Biofeedback
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.
In supine lying or sitting, Patient is asked to press down knee while contracting Quadriceps muscles.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Numeric Pain Rating Scale (NPRS)
Time Frame: Post 6 Weeks
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
Time Frame: Post 6th week
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
Time Frame: Post 6th week
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 Outcome Measures

Outcome Measure
Measure Description
Time Frame
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
Time Frame: Post 6 weeks
Changes from the baseline, WOMAC is used to assess the functional status. The questionnaire includes five questions about pain severity (0-20), two items on joint stiffness (0-8), and 17 questions on functional limitations of the patient (0-68). Each item is scored on a scale of 0-4, and the greater the score, the worse the pain and function. The total score of the subjects from this index was reported from a total of 96.
Post 6 weeks
