Electric Muscle Stimulation, also known as EMS, sends mild electrical pulses through the skin to help stimulate injured muscles or manipulate nerves to reduce pain. EMS is a painless procedure that can accelerate healing time as well as provide relief from painful symptoms. EMS is similar to a TENS unit that you can use at home but provides a slightly stronger current for a greater benefit. Most of our patients with shoulder pain, neck pain, and lower back pain really enjoy this modality.
