Biofeedback is a great tool when our therapists are trying to retrain patterns of muscle recruitment. For example, after a shoulder injury or surgery, many of us compensate by using our upper trapezius when elevating the arm. Biofeedback helps by giving us instant feedback when the wrong muscle is activated at the wrong time.

Biofeedback is also good when a muscle is almost ready to be weaned off of E-stim, but still needs a little help. In that case, biofeedback allows the patient to do most of the work and then it kicks in a little E-stim at the end of the contraction for improved firing.
