how is surface EMG used for biofeedback?

uses electrodes not he surface of the skin to detect underlying intrinsic electrical activity of muscle tissue and converts this to extrinsic auditory, visual or tactile signal to the patient

what 3 things can surface EMG be used for?

-up train: improve muscle performance

-down train: decrease motor input to a muscle

-improve neuromuscular coordination

what is surface EMG commonly used for?

commonly used for muscle activity retraining
