Abstract

An electronic circuit for analog processing of neural (electroneurogram or ENG) and muscular (electromyogram or EMG) signals in functional electrical stimulation (FES) systems is described in this paper. The basic circuit consists of a low-noise gated preamplifier, band-pass filter, amplifier, and a blanking circuit to minimize stimulation artifacts during electrical stimulation. This device was tested in chronic recordings using a triphasic cuff electrode for nerves and epimysial electrodes for muscles in the hind limbs of cats. The device was used for nerve recordings in the presence of electrical stimulation of muscles in the same leg. The recordings showed rejection of stimulation and muscle (M-wave) artifacts, while retaining the information of interest.

摘要

本文描述了一种用于功能性电刺激（FES）系统中对神经（神经电图或ENG）和肌肉（肌电图或EMG）信号进行模拟处理的电子电路。基本电路由一个低噪声门控前置放大器、带通滤波器、放大器和一个消隐电路组成，以在电刺激期间将刺激伪影降至最低。该装置在慢性记录中进行了测试，使用了用于猫后肢神经的三相袖带电极和用于肌肉的肌外膜电极。该装置用于在同一条腿的肌肉进行电刺激的情况下进行神经记录。记录显示，该装置能够抑制刺激和肌肉（M波）伪影，同时保留感兴趣的信息。
