Why use surface electromyography?
SEMG is the only way that the dentist can accurately measure and record muscle status and function. Palpation is subjective at best, has little consistency from one dentist to another, and provides no objective documentation. SEMG allows the dentist to measure and record objective data concerning muscle status. The information can be invaluable as an aid in occlusal diagnosis and is highly useful in patient education. SEMG also enables studies of muscle function – showing precise timing and activation patterns of various muscle groups. This information is adjunctive to the occlusal diagnosis and is not otherwise available.
