Abstract

The results of an experimental electromyographic investigation of temporomandibular arthrokinetic reflex control of the mandibular musculature are reported. Co-ordinated, rapidly adapting and slowly adapting facilitatory and inhibitory reflex changes in motor unit activity in the mandibular musculature were evoked by graduated passive movements of the isolated (but innervated) temporomandibular joint. Induced dysfunction of regionally discrete groups of articular mechanoreceptors was shown to result in specific changes in static and dynamic reflex motor unit activity. The possible clinical significance of these changes is discussed.

摘要

本文报告了一项关于下颌肌肉颞下颌关节运动反射控制的实验性肌电图研究结果。通过孤立（但有神经支配）的颞下颌关节的分级被动运动，诱发了下颌肌肉运动单位活动中协调的、快速适应性和缓慢适应性的促进和抑制性反射变化。结果表明，局部离散的关节机械感受器组功能障碍会导致静态和动态反射运动单位活动的特定变化。本文还讨论了这些变化可能的临床意义。
