A new method is described that allows continuous quantification of parkinsonian and essential tremor over a period of up to 24 h on the basis of surface EMG recording from antagonistic forearm muscles. Tremor extraction from EMG data and all other calculations are performed on a digital computer. The occurrence, intensity and frequency of tremor are calculated. The data evaluation is fully automatic, including quality control and elimination of artifacts. Since tremor changes considerably over a 24 h period, long-term quantification gives more reliable data to study diurnal variations and to control the effects of medical treatment on tremor. As an additional advantage tremor recording is not restricted to a laboratory environment. Tremor can be monitored under everyday conditions and in the presence of moderate voluntary EMG activity.
本文描述了一种新方法，该方法基于对拮抗前臂肌肉的表面肌电图记录，能够在长达24小时的时间段内对帕金森震颤和特发性震颤进行连续定量分析。从肌电图数据中提取震颤以及所有其他计算均在数字计算机上进行。计算震颤的发生情况、强度和频率。数据评估完全自动化，包括质量控制和伪迹消除。由于震颤在24小时内变化很大，长期定量分析可为研究昼夜变化以及控制药物治疗对震颤的影响提供更可靠的数据。另一个优点是，震颤记录不限于实验室环境。可以在日常条件下以及存在适度自愿性肌电图活动的情况下监测震颤。
