使用便携式记录仪进行长期肌电图检查可以研究自然环境中的肌肉活动，以调查肌肉过度使用或口腔习惯是否可能导致咀嚼系统肌关节病的发生或持续。目前，人们对咀嚼肌长期行为知之甚少。这项初步研究的目的是定义参数，以便从肌电图形式自动识别不同类型的口腔活动。四名志愿者执行了一项包含功能性和副功能性活动的计划（总共 333 项功能性活动和 82 项副功能性记录）。采用自主研发的便携式智能固态记录仪记录咬肌和颞肌的肌电图。确定滑动窗口内的信号平均水平（mw）和动态（dw）。颞肌记录可以更好地区分功能和模拟功能异常。咬牙的平均MW为最大自愿咬牙时肌电图峰值的51.4 +/- 3.5%，磨牙的平均MW为21.2 +/- 2%。使用 dw/mw 作为参数，在 0.96 s 滑动窗口持续时间下，咬牙、磨牙和咀嚼信号具有最大分离度（平均值：咬牙为 0.16 +/- 0.01，磨牙为 0.39 +/- 0.01，咀嚼为 0.88 +/- 0.01）。
Long-term electromyography with portable recorders allows the study of muscle activity in the natural environment to investigate whether muscle overuse or oral habits may contribute to initiate or perpetuate a myoarthropathy of the masticatory system. At present, little is known about the behaviour of masticatory muscles over long time periods. The aim of this preliminary study was to define parameters which allow the automatic recognition of different types of oral activities from the electromyogram form. A programme with functional and parafunctional activities was performed by four volunteers (total of 333 functional and 82 parafunctional recordings). Electromyograms of the masseter and temporal muscles were recorded by means of a self-developed portable intelligent solid state recorder. Signal mean level (mw) and dynamics (dw) within a sliding window were determined. Temporal muscle recordings allowed better discrimination between function and simulated parafunction. The average of mw for clenching was 51.4 +/- 3.5% and for tooth grinding 21.2 +/- 2% of the peak electromyogram value at maximum voluntary clench. At 0.96 s sliding window duration, clenching, tooth grinding and chewing signals had maximum separation, using dw/mw as parameters (average: 0.16 +/- 0.01 for clenching, 0.39 +/- 0.01 for teeth grinding and 0.88 +/- 0.01 for chewing).
