适用范围/预期用途
临床肌电图和诱发电位的记录，用于神经肌肉疾病的辅助诊断。
一、工作原理 (Working Principle)
中文通过电极采集神经与肌肉的微伏级生物电信号，经高精度放大器放大、滤波去除噪声（如 50Hz 工频干扰），再经 A/D 转换为数字信号，由计算机分析波形参数（潜伏期、波幅、传导速度）。肌电图（EMG）记录肌肉自发电位与运动单位电位；诱发电位（EP）通过电 / 声 / 光刺激神经通路，记录中枢与外周的诱发反应。
EnglishCollects microvolt-level bioelectrical signals of nerves and muscles via electrodes. Signals are amplified by high-precision amplifiers, filtered to remove noise (e.g., 50Hz power frequency interference), converted to digital signals via A/D conversion, and analyzed by a computer for waveｆorm parameters (latency, amplitude, conduction velocity). Electromyography (EMG) records spontaneous and motor unit potentials of muscles; Evoked Potentials (EP) record evoked responses of central and peripheral pathways via electrical/acoustic/visual stimulation.
