简要总结
This study intends to determine the Effects of Electromyographic biofeedback on performance of vastus medialis oblique muscle in knee osteoarthritis.
详细描述
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

研究组 & 干预措施
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.
干预措施: Electromyographic Biofeedback (Device)
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.
干预措施: Quadriceps Isometric exercises (Other)
结局指标
主要结局
Vastus medialis Oblique(VMO) Thickness
时间窗: 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)
时间窗: 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
时间窗: 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.
次要结局
- Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)(Post 6 weeks)
