三个正常的成年受试者拍摄使用侧视，高速电影放射线摄影测量的运动量的外部皮肤点的下颌骨相对于下面的颌骨。将金属标记物固定在皮肤上，以模拟钳口运动的应变计转换中常用的悬臂梁连接点。颏标记相对于颌移动的标准差在前后方向上为0.52至1.28 mm，在上下方向上为0.67至2.31 mm。下唇和下巴标记位置在上下方向上高度相关。下巴标记的位置往往是更上级，在一个主题，更前唇比非唇不同的背景。在两种不同的情况下，变异程度并没有系统性的不同。
Three normal adult subjects were filmed using lateral-view, high-speed cineradiography to measure the amount of movement of external skin points on the jaw relative to the underlying jaw bone. Metal markers were secured to the skin to simulate cantilever beam attachment points commonly utilized in the strain gauge transduction of jaw movements. Standard deviations of chin marker movement relative to the jaw ranged from 0.52 to 1.28 mm in an anterior-posterior direction and 0.67 to 2.31 mm in a superior-inferior direction. Lower lip and chin marker positions were highly correlated in the superior-inferior direction. Chin marker positions tended to be more superior and, in one subject, more anterior for labial than for nonlabial different contexts. The degree of variability was not systematically different for the two different contexts.
