项目摘要

Although it has been clearly shown that changes occur in the chronological elements, integration potential and frequency, etc. of surface electromyogram (EMG) burst in patients with temporomandibular arthrosis, there are still many factors which remain unclear. In order to apply EMG parameters to diagnosis, examination from a wide range of aspects of the muscular activity involved in movement can be considered. Examples of these include (1) timing, (2) amount of change in strength as well as direction (Velocity), (3) response to an input signal, (4) aspects of destination activities, and (5) allocation of functions. Moreover, it is obviously also necessary to systematically analyze as much data as possible from the viewpoint of dispersion between individual patients. Based on the above viewpoints, the research for this year involved : (1) an attempt to graphically represent the normal and abnormal states of mandibular function using a topograph (No. 200) purchased in 1989, together wit … More h making corrections in the program necessary for operation ; (2) the continuing of gathering of data from subjects with mandibular function abnormalities which matched these conditions ; (3) the grouping of each of the types of symptoms based on the data that had been collected (consisting of the three major typical symptoms of pain in the TMJ region, joint sounds and dyskinesia, along with the classification of type I through type V that have recently been advocated in temporomandibular arthrosis seminars), followed by the beginning of quantitative analysis of EMG parameters ; and, (4) the collecting of data from normal subjects separate from the identification of normal and abnormal states, and the establishment of normal values based on that data.Furthermore, as there were. many cases in which the interval between discharges in the EMG wave forms of subjects with abnormal mandibular function were not clear-cut, corrections were made to allow use of the date for practical use by examining those portions of the wave form that are required in order to be able to perform graphic representation. However, additional studies regarding this point are still necessary.Notwithstanding, as a result of performing the above, it became clear as to which of the various extracted EMG parameters are useful with respect to mandibular function abnormalities, and with respect to temporomandibular arthrosis in particular. As such, it became possible to a certain extent to obtain reference materials for coding of those parameters as well as perform graphic representation in terms of practical application. However, with respect to temporomandibular arthrosis, since this inevitably includes cases accompanied by defects (site and number of defects) as well as cases of psychogenic stress, the further continuation of this research is believed to be important.

虽然颞下颌关节病患者的表面肌电图（EMG）爆发的时间要素、积分电位、频率等都有明显的改变，但仍有许多因素尚不清楚。为了将EMG参数应用于诊断，可以考虑从运动中涉及的肌肉活动的广泛方面进行检查。例如，（1）定时，（2）强度和方向的变化量（速度），（3）对输入信号的响应，（4）目的地活动的方面，（5）功能的分配。此外，从个体患者之间的分散的观点出发，显然也需要系统地分析尽可能多的数据。基于上述观点，本年度的研究包括：（1）尝试使用1989年购买的地形图（No.200）以图形方式表示下颌功能的正常和异常状态， ...更多信息（2）继续收集符合条件的下颌骨功能异常受试者的资料;（3）根据收集的数据对每种症状进行分组（由颞下颌关节区疼痛、关节音和运动障碍三大典型症状组成，沿着最近在颞下颌关节病研讨会上提倡的I型到V型的分类），随后开始EMG参数的定量分析;以及，（4）从正常受试者收集与正常和异常状态的识别分开的数据，并根据这些数据建立正常值。此外，由于有。在许多情况下，具有异常下颌功能的受试者的EMG波形中的放电之间的间隔不明确，通过检查波形中为了能够进行图形表示所需的那些部分，进行校正以允许将数据用于实际应用。然而，关于这一点的进一步研究仍然是必要的。尽管如此，通过执行上述操作，我们清楚地知道提取的各种EMG参数中哪些参数对于下颌功能异常有用，特别是对于颞下颌关节病。因此，在一定程度上有可能获得用于对这些参数进行编码的参考材料，并根据实际应用进行图示。然而，对于颞下颌关节病，由于这不可避免地包括伴有缺陷的病例（缺陷的部位和数量）以及心因性应激的病例，因此进一步继续进行这项研究被认为是重要的。少
