What Is Biofeedback Training Like?
Surface electromyography, or EMG biofeedback, makes it possible to see when you are tensing muscles and unnecessarily during habitual activities. Unlike needle electromyography, a medical-diagnostic procedure, EMG biofeedback involves placing flat, not sharp, sensors on the surface of the skin over the muscles to measure the amplitude of the electrical signals that tell muscle-fibers to contract. Guided in relaxing by the feedback, you learn new skills and habits that enable recovery from pain. The biofeedback equipment is either connected to a computer, which allows you to see your actual reactions, or to a device that emits sounds.
