​This treatment is performed in our office, and 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, location and how deep the therapy will be. The electrical current causes the muscles to experience small but quick contractions. During treatment, patients may feel a prickly or tingling sensation; however, these sensations will subside after the machine is turned off, or shortly afterward and is no cause for alarm. ​ Electrical muscle stimulation creates tiny contractions in the muscles so they become tired and relax, relieving pain and muscle spasms. In addition, it triggers the release of endorphins, which are our body’s natural pain reliever. The process is also said to clear metabolic waste so nutrients can be better delivered and soft tissue can heal more quickly. Back muscles and neck muscles are common locations for electrotherapy; however, there are many areas of the body that can experience the benefits of this treatment. Electric muscle stimulation works well for both acute and chronic pain. ​ ​
