项目摘要

In 1989, we developed an autonomic response analyzing system atic chances of electroencephalogram(EEG), microvibration(MV), electromyogram(EMG), electrocardiogram(ECG), and prethysmogram(PTG)before, during, and after stress sessions. In 1990, we developed an masticatory muscle EMG analyzing system during clenching tusk and gum-chewing. These systems actually had greater value to find the intrinsic parameters of the mandibular function. In 1991, by combining these systems, we expanded the project to find the proper condition of masticatory muscle relaxation training with help of the frontal muscle. EMG biofeedback-training(BFT)in terms of the training time of the session. Sixteen dental students were selected to be subjects. EEG, EMG, ECG, PTG, and respiration curve were recorded during the sessions of stress free, stress, and BFT. Frontal muscle EMG was amplified and transferred to the sound signal so that the subject could recognize his/her EMG activity auditory manner. The results are as follows.1) The most effective training time period seemed to be 7 min in the BFT session.2) It was obvious that the more repeating BFT session, the longer the skill of reducing EMG activity could last.3) The skill of reducing EMG activity expanded not only the frontal muscle itself but also the muscles around it.4) Although the EMG activity in the masseter and the temporal muscles were reduced by BFT, those of the sternocleidomasdoid muscle showed little change under condition of stress and autonomic response can not be controlled by BFT.

在1989年，我们开发了一个自主反应分析系统的脑电图（EEG），微振动（MV），肌电图（EMG），心电图（ECG），和胸腺前波（PTG）之前，期间，和之后的压力会议的自动机会。1990年，我们研制了一套咀嚼肌肌电分析系统。这些系统对于寻找下颌功能的内在参数具有较大的应用价值。1991年，通过结合这些系统，我们扩大了该项目，以找到合适的条件下，咀嚼肌放松训练的帮助下，额肌。肌电生物反馈训练（BFT）的训练时间。十六名牙科学生被选为受试者。记录无应激、应激和BFT时的EEG、EMG、ECG、PTG和呼吸曲线。额肌肌电被放大并转换为声音信号，使受试者能够识别他/她的肌电活动听觉方式。结果表明：1）最有效的训练时间段似乎是7分钟的BFT会议。2）显然，更多的重复BFT会议，减少肌电活动的技能持续的时间越长。3）减少肌电活动的技能不仅扩展了额肌本身，而且扩展了额肌周围的肌肉。虽然BFT降低了咬肌和颞肌的肌电活动，但胸锁乳突肌的肌电活动在应激状态下变化不大，BFT不能控制自主神经反应。
