EMG Biofeedback is a device used to retrain muscles that commonly "turn off" in the presence of pain. The most common of these is VastusMedialis Oblique (VMO) in the presence of knee pain that can effect any age.
It is a non-painful, non-invasive apparatus that measures the amount of 'activity' in a muscle upon movement and provides feedback to the patient with a visual scale. The patient can use that feedback as well as the physiotherapist's advice to improve the quality of their muscle activity. This ineveitable leads to improved function and reduced pain and is a highly successful and well researched modality.
This modality is used as standard protocol for treating our patients at myphysio.
