先前的工作表明，持续的低水平咬合与肌源性颞下颌关节紊乱病(TMD)疼痛的病因学有关。这项研究旨在建立一个可靠的系统来评估与低水平咬合有关的低水平肌电活动，同时区分语音活动，这是最常见的面部肌肉活动之一，可与低水平咬合区分。该装置可用于临床评估TMD患者的清醒肌肉活动。8名女性和8名男性受试者(38个中心点，9+/-11个中心点，3岁)参加了这项研究，以评估言语时长估计的有效性。实际的讲话时长由一名考官通过在Wave编辑软件上指出每一次讲话的开始和结束的时间来定义。当语音响度为54中心点71+/-5中心点00分贝时，语音传感器系统检测到的语音时长与上述实际语音时长显著相关(P
Previous work suggests a relationship between sustained low-level tooth clenching and the aetiology of myogenous temporomandibular disorder (TMD) pain. This study aimed to establish a reliable system with which to evaluate low-level electromyographic (EMG) activity related to low-level tooth clenching while discriminating speech activity, which is one of the most common facial muscle activities to be discriminated from low-level clenching. This device should facilitate the clinical evaluation of awake muscle activity in TMD patients. Eight female and eight male subjects (38 center dot 9 +/- 11 center dot 3years) participated in the study to evaluate the validity of estimation of speech duration. Actual speech duration was defined by one examiner by pointing out the timing of beginning and end point of each speech on wave-editing software. Speech duration, as detected by a voice sensor system, which was activated by a voice loudness of 54 center dot 71 +/- 5 center dot 00 dB, was significantly correlated with the above actual speech duration (P
