The effect of a sustained isometric retrusive contraction on maximum voluntary retrusive force levels was measured in normal jaw function. Surface electromyographic recordings of the suprahyoids, masseter and posterior temporalis were taken and force was measured with a force transducer. Subjects sustained isometric force at the 25, 50, 75 and 100 per cent(More)
Eight normal male volunteers performed 4 repeated sustained voluntary isometric protrusive jaw muscle contractions of 25, 50, 75 and 100% of maximum effort. Each contraction was sustained until maximum pain tolerance was reached, and all 4 contractions were completed within a single 120-min experimental period. A 30-min rest period followed each sustained(More)
