Although the silent period duration has often been evaluated as a potential indicator of stomatognathic system dysfunction, there is still some uncertainty as to its normal biologic variation. This study investigated the subject variation in the silent period in a group of 22 young and healthy subjects under standardized conditions. Electromyographic recordings were obtained from the masseter muscle at 40% clenching after chin taps. Four different patterns of the silent period were recorded: one simple and three combined. Although the latencies of the early and late phases of depression were generally consistent, the results for duration were more variable and depended on the pattern of the silent period.
尽管静息期时长常被评估为口颌系统功能障碍的一个潜在指标，但其正常生物学变异仍存在一些不确定性。本研究在标准化条件下，对一组22名年轻健康受试者的静息期个体差异进行了调查。在颏部轻叩后，以40%的咬合力从咬肌获取肌电图记录。记录到了静息期的四种不同模式：一种单一模式和三种组合模式。尽管抑郁早期和晚期阶段的潜伏期总体一致，但时长结果的变异性更大，且取决于静息期的模式。
