1 We studied to evaluate an constitution of motor program regulating repetitive jaw movementment. The orbits of' jaw movement and mobility of various sites of the body and their accseleration were observed. Results obtained were as follows ;2. During the jaw tapping movement, forehead mobilities in the oppsite direction to the ones of mentum were observed in 94.0% of the storokes around the onsets of jaw open movement, and in 96.5%at the beginning of jaw close movement.3. Furthermore, it was confirmed that these head mobilities became to be larger with increasement of jaw opening distance and of tapping intensity.4. The impacts exerted on the tooth by jaw tapping were propagated to distal sites of limbs through the bones and soft tisses. These implied that the propagated vibration would influence the whole of' the body. On the other hand, as the amplitude of propagated vibration stimulus was influenced by posture, the posture during jaw functioning appears to be important on the reguration and retention of jaw function.5. The jaw tappinng force was regulated by alteration of the jaw opening distance, the duration of the tooth contact phase, the duration of the jaw closing phase, the maximum jaw opening velocity, and the maximum jaw closing velocity. However, the duration of the jaw opening phase and cycle time were not affected by the force reguration under our experimental conditions.6. We consider that above results imply an constitution of motor program regulating repetitive jaw movement to be layered

1.本研究旨在评价一种调节重复性下颌运动的运动程序的构成。观察了下颌运动轨迹、身体各部位活动度及增快情况。获得的结果如下;2。在叩击下颌运动中，94.0%的人在下颌张开运动开始时和96.5%的人在下颌闭合运动开始时出现了与颏部运动方向相反的额部运动.此外，还证实了这些头部活动度随着钳口张开距离和攻丝强度的增加而变大.下颌叩击对牙齿的冲击力通过骨骼和软组织传递到四肢远端。这意味着传播的振动会影响整个身体。另一方面，由于振动刺激的传播幅度受姿势的影响，因此，下颌功能的恢复和保持与姿势有关.通过改变颌骨张开距离、牙齿接触阶段的持续时间、颌骨闭合阶段的持续时间、最大颌骨张开速度和最大颌骨闭合速度来调节颌骨张开力。然而，在我们的实验条件下，力的再调节并不影响下颌张开阶段的持续时间和循环时间。我们认为上述结果暗示了调节重复性颌运动的运动程序的构成是分层的
