Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

There will be two treatment groups of participants, Experimental group will receive Isometric exercises with EMGBF( Electromyographic Biofeedback ) and control group receive exercises without EMGBF.

Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Participants

There will be two treatment groups of participants, Experimental group will receive Isometric exercises with EMGBF( Electromyographic Biofeedback ) and control group receive exercises without EMGBF.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

Electromyographic Biofeedback

Intervention Type 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

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.

Group Type ACTIVE_COMPARATOR

Quadriceps Isometric exercises

Intervention Type OTHER

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