Human variability in the measurement of the masseteric silent period (SP) was quantified. There were significant differences among (1) observer groups (technicians and dental students), (2) individual observers, (3) repeated measures of the same SP, and (4) trials. No significant observer bias was found. SP's were significantly longer at an inter-incisal distance of 10 mm (48.8 +/- 5.4 ms) than at 14 or 19 mm (44.7 +/- 9.8 ms, 44.5 +/- 6.5 ms).
对咬肌静息期（SP）测量中的个体差异进行了量化。在以下方面存在显著差异：（1）观察组（技术人员和牙科学生）之间；（2）个体观察者之间；（3）同一SP的重复测量之间；以及（4）试验之间。未发现明显的观察者偏差。在切牙间距离为10毫米时SP明显更长（48.8±5.4毫秒），而在14或19毫米时则较短（44.7±9.8毫秒，44.5±6.5毫秒）。
