A system for continuously quantifying of jaw movements in terms of jaw angle was tested in combination with a previously tried method for simultaneous recording of temporomandibular joint (TMJ) sounds and electromyographic (EMG) activity. The system was used to measure the degree of rotation of the lower jaw in the sagittal plane in relation to the upper jaw. It was tested on a group of healthy subjects and patients with TMJ clicking and found useful to record EMG activity and TMJ clicking in relation to opening degree and velocity of jaw movement in open-close cycles.
一种根据下颌角度持续量化下颌运动的系统，与之前尝试的同时记录颞下颌关节（TMJ）声音和肌电图（EMG）活动的方法相结合进行了测试。该系统用于测量下颌在矢状面相对于上颌的旋转程度。它在一组健康受试者和患有颞下颌关节弹响的患者身上进行了测试，发现对于记录肌电图活动以及与开闭口周期中下颌运动的开度和速度相关的颞下颌关节弹响很有用。
