Beijing Chinese Subtitling Translation Service Agency has translated many technical documents about EMG and Types of EMG.

Types of EMG  肌电图的类型
Surface EMG is “kinesiological”
     表面肌电图具有“运动机能学”意义
it just shows whether EMG activity is increasing or decreasing globally
  仅仅反映肌电图活动是否整体性增加或者降低
shows little about form of EMG signal (which can be diagnostic of muscle or neural pathology)
   不能反映肌电图信号的形式（肌电图信号的形式可进行肌肉或者神经病理学诊断
To show the form of the signal needle or wire electrodes are needed
     显示出肌电图信号的形式需要针电极或者丝电极
Unpleasant and unusual in urodynamic work
     在尿流动力学检测中让人产生不舒服感，不常用
Measure from a small part of muscle 只测量一小部分肌肉
Tend to give more variable signals 倾向于产生变异性更大的信号
