Title: Electromyographic biofeedback and sustained masseter muscle contraction in man. Author: Watkinson AC. Journal: J Oral Rehabil; 1988 Jul; 15(4):353-9. PubMed ID: 3171757. Abstract: Twenty-two human subjects performed sustained voluntary contractions of the mandibular elevator muscles firstly without and secondly with visual biofeedback. The level of electromyographic activity of the masseter muscle during the second clench exceeded that during the first clench by a mean of 36%. This differential indicates the ability of the subjects to override the central factors which normally limit muscle activity during a fatiguing contraction.[Abstract] [Full Text] [Related] [New Search]
