一些研究已经研究了下颌运动和头部或身体姿势之间的功能关系，但在下颌运动过程中头部和身体的运动还没有得到广泛的研究。10名健康受试者进行重复下颌敲击运动。压电加速度计被贴在参与者的前额、颏的表面，以及第六颈椎、第十二胸椎和第三腰椎的棘突上。观察了下颌叩击第6次至第25次期间，下颌张开和闭合开始前后加速度信号出现的方向。在开颌开始前后，前额和腰椎有向后移动的趋势，而颈椎和胸椎有明显的向前移动的频率。这些部位的运动方向在下颌闭合开始时发生了逆转;因此，前额和腰椎的运动再次与颈椎和胸椎的运动相反。结果表明，下颌开合运动时，头部的伸屈运动常伴随着下颌的开合运动，颈部和躯干的运动也存在，这将有助于促进下颌运动的顺利进行。
Several studies have examined the functional relationship between mandibular movement and head or body posture, but head and body motion during jaw movement have not been extensively investigated. Ten healthy participants performed repetitive jaw tapping movement. Piezoelectric accelerometers were attached on the surfaces of the participant's forehead, mentum, and over the spinous processes of the sixth cervical, twelfth thoracic and third lumbar vertebrae. The direction in which the antero-posterior acceleration signals appeared around the onsets of jaw opening and closing were observed for the period from the 6th to the 25th strokes of the jaw tapping. Around the onset of jaw opening, the forehead and the lumbar vertebra tended to move posteriorly, but the cervical and thoracic vertebrae moved anteriorly with significant frequencies. The directions of the motions of these locations reversed themselves at the beginning of jaw closing; so the motions of the forehead and the lumbar vertebra were opposed again to the ones of the cervical and thoracic vertebrae. The results suggest that the head extend-flex motion often accompanied the jaw open-close movement, and the motions of the neck and trunk existed, which would serve the purpose of promoting the mandible to move smoothly.
