Electromyography (EMG) is an electrodiagnostic technique for recording the extracellular activity of skeletal muscles at rest, during voluntary contractions, and during electrical stimulation. Needle EMG, the gold standard for evaluating the electrical activity of muscles, is an invasive procedure that records the activity of individual muscles. Surface EMG records the electrical activity of groups of muscles through placement of electrodes on the surface of the skin.
Surface EMG (SEMG) may be characterized in several ways, including but not limited to paraspinal, high-density (more than 2 closely spaced electrodes), dynamic (performed during or after exercise) or macro (more than one muscle fiber) SEMG. The technology has been proposed for a variety of clinical indications including: clarification of a diagnosis (i.e., muscle, joint, or disk disease), follow-up of acute back pain, evaluation of exacerbation of chronic back pain, evaluation of pain management treatment techniques, and evaluation and monitoring of temporomandibular disorder (TMD).
The use of surface electromyography (SEMG) is considered EXPERIMENTAL/INVESTIGATIVE for all indications, including temporomandibular disorder (TMD), due to lack of clinical evidence indicating its impact on improved health outcomes.
