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

- •Age : In between 45 - 65years
- •Both Genders
- •Subjects with a definite diagnosis of knee OA according to the guidelines of the American College of Rheumatology with at least 6 months of knee pain.
- •Grade 1 or 2 joint cartilage degradation based on the Kellgren-Lawrence classification
- •Body mass index (BMI) of \<35 kg/m2
Exclusion Criteria
- •Subjects who had undergone physical therapy or intraarticular injection in the past 3 months

Outcomes
Primary Outcomes
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
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.
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.
Secondary Outcomes
- Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)(Post 6 weeks)
