This treatment is performed here in our office, and usually only takes a few minutes. Electrodes are placed on the skin over the affected area, and the machine is turned on. An electrical current is then transmitted into the soft tissue or muscle. The level of current used depends on the injury, its location, and how deep the therapy will be. This electrical current causes the muscles to experience very small but quick contractions. During the treatment, patients may feel a prickly or tingling sensation; however, these sensations will subside after the machine is turned off, or shortly afterward. Many patients enjoy the sensation.
