研究了空开-合-紧循环的重现性。4名受试者被要求以S-1动作的1/2、1、2个周期各进行30次空开合握动作，共3次。为了描述这样的一系列30个动作，选择了一组9个参数。通过参考这些参数，研究人员发现，受试者并不总是能够在一次重复测试中准确地再现一系列30个动作。运动参数强烈依赖于运动的频率。随着频率的增加，运动周期被划分的持续时间减少，而打开和关闭时的最大颌骨速度和接触牙齿之前的颌骨速度增加。被选来描述动作流畅度的参数值表明，动作执行的频率越高，动作越流畅。
The reproducibility of the empty open-close-clench cycle has been investigated. Four subjects were asked three times to perform thirty empty open-close-clench movements at each frequency of 1/2, 1 and 2 cycles s-1. To describe such a series of thirty movements a set of nine parameters were selected. By reference to these parameters it was found that the subjects were not always able to exactly reproduce a series of thirty movements at a repeat test. The movement-parameters strongly depended on the frequency of the movements. On increasing the frequency the durations of time in which a movement cycle was divided decreased, while the maximum jaw speeds during opening and closing and the jaw speed just before tooth contact increased. The parameter values chosen to describe the smoothness of the movements performed, indicated that the smoother movements were executed at the higher frequencies.
