The apparent involuntary single motor unit discharges observed in many extremity muscles of spastic patients necessitate monitoring raw electromyography during training sessions. The clinician should note that electronic components of some biofeedback instruments may amplify and distort these units so that the feedback, whether by meter or by variable pitch tone, may erroneously be perceived by the patient as a high level of muscle tension.
在痉挛患者的许多肢体肌肉中观察到的明显的非自愿单个运动单位放电，使得在训练期间有必要监测原始肌电图。临床医生应注意，一些生物反馈仪器的电子元件可能会放大和扭曲这些运动单位，以至于无论是通过仪表还是通过可变音调，反馈都可能被患者错误地感知为高水平的肌肉紧张。
