Vibration of the masseter and temporalis muscles in normal human adult subjects elicits a tonic vibration reflex with unexpected features. The electromyographic response is not asynchronous as in the limb muscles, but involves well-defined spikes with a one-to-one temporal relation to the vibration cycles. The effect of various parameters such as muscle stretch, vibration frequency or amplitude, etc, has been investigated. The small latency fluctuation of the vibration-induced spikes is compatible with a monosynaptic reflex mechanism which is considered to be assisted by a polysynaptic facilitatory background of proprioceptive origin.
在正常成年人类受试者中,咬肌和颞肌的振动会引发具有意外特征的紧张性振动反射。肌电图反应不像肢体肌肉那样异步,而是涉及与振动周期具有一一对应时间关系的明确尖峰。已经研究了各种参数的影响,如肌肉拉伸、振动频率或振幅等。振动诱发尖峰的微小潜伏期波动与单突触反射机制相符,该机制被认为由本体感受起源的多突触易化背景所辅助。
