Just as it suggests, electricity can be utilized to stimulate the cells of diseased muscles and nerves. The most common forms of electrical stimulation (ES) in physical rehabilitation are neuromuscular electrical stimulation (NMES) and transcutaneous electrical nerve stimulation (TENS). Through the use of strategically placed electrode pads over the affected muscle groups, the muscles and nerves are stimulated using a specific timed frequency. The most common condition that our muscles are affected by is muscular weakness. NMES is often utilized to address this condition by stimulating muscle contraction. This is especially useful following orthopedic surgery. TENS is most commonly used for pain relief by providing sensory-level stimulation versus motor nerve stimulation that is utilized in NMES.
