Visual and Auditory Electromyography Biofeedback Among Stroke Patients
Sponsor: University of Lahore
Summary
Stroke commonly results in impairments of balance, mobility, and lower extremity motor function that limit independence in daily activities. Electromyography (EMG) biofeedback enhances motor relearning by providing real-time feedback regarding muscle activation. Although both visual and auditory EMG biofeedback have demonstrated benefits in stroke rehabilitation, evidence directly comparing these feedback modalities remains limited. This randomized controlled trial aims to compare the effects of visual and auditory EMG biofeedback, each combined with conventional physiotherapy, on balance, functional mobility, motor function, and functional independence in individuals with stroke.

Interventions
Visual Electromyography Biofeedback
Surface electromyography biofeedback will provide real-time visual feedback of muscle activity from the tibialis anterior muscle using graphical displays on a monitor. Participants will perform task-oriented lower extremity exercises while observing muscle activation to facilitate motor relearning and improve balance, functional mobility, and lower extremity motor function. The intervention will be delivered for 20 minutes per session, five sessions per week for three weeks.
Auditory Electromyography Biofeedback
Surface electromyography biofeedback will provide real-time auditory feedback corresponding to muscle activation of the tibialis anterior muscle. Participants will perform task-oriented lower extremity exercises while using auditory cues to facilitate muscle activation, movement coordination, and motor recovery. The intervention will be delivered for 20 minutes per session, five sessions per week for three weeks.
Conventional Physiotherapy
Conventional physiotherapy will consist of lower extremity strengthening exercises, task-oriented functional training, balance exercises, gait training, stretching, and mobility exercises. All participants will receive 10 minutes of conventional physiotherapy before EMG biofeedback during each treatment session. The intervention will be delivered five sessions per week for three weeks.
