Electromyographic biofeedback (EB) detects and amplifies neurological activity and converts it to auditory and/or visual signals. EB serves as an adjunct treatment for muscle re-education, strengthening, or relaxation by measuring electrical activity in muscles and providing feedback to help restore normal neurological pathways. Basic EB units have silver electrodes that measure electrical activity in muscles to provide feedback and help patients re-establish motor control inhibited by conditions like injury or immobilization.
