Kinesthetic experience accompanying vibration of human jaw muscles was investigated in 12 healthy subjects. Vibration of the masseter muscle with the jaw in a 20-mm opened position caused the subjects either to underestimate jaw closing effects or to experience jaw opening movements depending on whether the mandible was free to move or kept in a constant position. During vibration of the depressor muscles with the mandible in its rest position the subjects underestimated an opening movement, but fixation of the mandible caused no illusions of movement. All kinesthetic illusions perceived during vibration corresponded to elongation of the muscles under study beyond their actual length. Distortion of kinesthesia was independent of the amplitude and frequency of vibration and it persisted during anesthesia of the temporomandibular joints and loading of the mandible. It can be concluded that jaw muscle receptors may contribute to mandibular kinesthesia.
在12名健康受试者中研究了人类颌肌振动时的动觉体验。在颌处于20毫米张开位置时咬肌振动，根据下颌是自由移动还是保持在固定位置，受试者要么低估颌闭合效果，要么体验到颌张开运动。在下颌处于休息位置时降下唇肌振动期间，受试者低估了张开运动，但下颌固定不会引起运动错觉。振动期间感知到的所有动觉错觉都对应于所研究肌肉伸长超过其实际长度。动觉扭曲与振动的幅度和频率无关，并且在颞下颌关节麻醉和下颌加载期间持续存在。可以得出结论，颌肌感受器可能有助于下颌动觉。
