This paper describes the design of a digital signal processor based system for a personal computer for EMG data acquisition to monitor muscle activity during gait and to estimate the power spectrum of the acquired data under normal and pathological conditions. It also gives the hardware details of the velocity meter which is used to monitor the muscle activity with speed of walking. Software has been developed for system initialization, data acquisition, processing of acquired data, and data display for five channels. The developed equipment will be useful to clinicians for enhancing the understanding of a patient's dynamic performance.
本文描述了一种基于数字信号处理器的系统设计，该系统用于个人计算机进行肌电图（EMG）数据采集，以监测步态期间的肌肉活动，并估计正常和病理条件下采集数据的功率谱。它还给出了用于以步行速度监测肌肉活动的速度计的硬件细节。已开发出用于系统初始化、数据采集、采集数据处理以及五个通道数据显示的软件。所开发的设备将有助于临床医生更好地理解患者的动态表现。
