肌电反馈仪
EMG feedback equipment
肌电反馈仪(EMG feedbaek equipment)能测定身体表面肌电电压的幅度并显示反馈指示信号的生物反馈仪器。EMG反馈仪的传感器是银/氯化银材料制成的表面电极，仪器的电路部分包括差分放大器(放大有用信号，抑制无用信号)、信号滤波器(选择肌电信号中特定的频率成分)、检波器(将交流信号转换成直流信号)、积分器(收集、存储、累积输入信号)、电平检测器(自动比较被测信号与预定信号大小)和视觉或听觉反馈信号。大多数EMG反馈仪的精度在]0%一15%范围之间，高精度的EMG反馈仪能分辨肌电信号的微小变化，一个病人通过放松训练使其肌电压降至2微伏，则实际的电压误差为士0.2一士0.3微伏。一般 EMG反馈仪都有调节放大器增益的控制开关，当肌电压己经降到几个微伏时，加大增益便能察觉0.1微伏的肌电压变化。仪器的阂限开关则是设定训练所要达到的标准。肌电反馈仪是最常用的生物反馈仪器。理想的肌电反馈仪应具备体积小、精度高、功能全、便于操作、有数据处理功能等优点。 (杨立能撰梁宝勇审)
