A system for simultaneous measurement of surface EMG, joint movement and temporal parameters of gait has been developed for clinical use. Some design constraints, imposed by the clinical situation, are indicated. Multiple cycles of movement are recorded and averaged patterns of muscle activation and joint movements are determined. Data processing runs concurrently with data acquisition, so that the results are available for clinical interpretation immediately after the measurement. Instrumentation, signal processing and software are described and some examples of application of the system for evaluation of therapies and functional aids are presented. It is proposed that clinically relevant quantitative information can be obtained by comparison of different recordings of the individual patient rather than comparison with patterns found with normal subjects.
已开发出一种用于同时测量表面肌电图、关节运动和步态时间参数的系统以供临床使用。文中指出了临床情况所带来的一些设计限制。记录多个运动周期，并确定肌肉激活和关节运动的平均模式。数据处理与数据采集同时进行，以便测量后立即得到可用于临床解读的结果。文中描述了仪器、信号处理和软件，并给出了该系统用于评估治疗方法和功能性辅助器具的一些应用实例。有人提出，通过比较个体患者的不同记录而非与正常受试者的模式进行比较，可以获得临床相关的定量信息。
