A new method of prolonged recording of EMG provides a good estimate of spontaneous and induced diurnal variations in resting tremor in Parkinson's disease. It provides a record and a measure of the effects of treatment. Tremor intensity shows considerable variations even over short periods of time. Therefore short-term measurements of tremor are unhelpful. Long-term recordings agree better with the patient's assessment than with the clinical rating score. Repeated recordings over a similar 10-h period on 3 consecutive days in one patients showed fairly constant measures of occurrence and intensity of tremor. In contrast to accelerometer measurements of tremor, artefacts caused by movements and general activity of the patient do not materially interfere with tremor evaluation using surface EMG.
一种延长肌电图记录时间的新方法，能很好地评估帕金森病静止性震颤的自发和诱发昼夜变化。它提供了治疗效果的记录和测量方法。即使在短时间内，震颤强度也会有很大变化。因此，短期震颤测量并无帮助。长期记录与患者的自我评估比与临床评分更相符。在一名患者连续3天的类似10小时时间段内进行重复记录，结果显示震颤的发生频率和强度测量值相当稳定。与震颤加速度计测量不同，患者运动和日常活动引起的伪迹不会严重干扰使用表面肌电图进行的震颤评估。
