Clinical relevance of surface EMG of the masticatory muscles. (Part 1): Resting activity, maximal and submaximal voluntary contraction, symmetry of EMG activity.

摘要: Based on a comprehensive computerized literature search supplemented by specific manual of the literature, present review article focuses concrete aspects application surface electromyography (EMG) for evaluation masticatory muscles in general and masseter anterior temporal particular, presents current base knowledge clinical relevance EMG dental applications. In first stage review, publications from year 2000 or later reporting results controlled trials (randomized as far available) patients with craniomandibular temporomandibular disorders (TMD) were analyzed. Data selected systematically compiled divided into subject areas follows: Resting activity, maximal sub-maximal voluntary contraction, symmetry fatigue effects; activity during mastication, factors (including pain) that affect impact adjusting static dynamic occlusal relationships; Effects splints other treatments. Surface is principle suitable tool neuromuscular function analysis field dentistry. If used according to recommendations conjunction thorough conscientious history physical examination, measurements can provide objective, documentable, valid, reproducible data functional condition an individual patient.
