Six athetoid cerebral palsy patients participated in the following: speech and motor prebiofeedback training evaluation; frontal EMG biofeedback training, 6 wk; speech and motor postbiofeedback training evaluation. Frontal pretraining levels for the subjects averaged 28.9 muV p-p. Subjects' feedback consisted of an auditory signal (clicks) varying proportionately with frontal EMG activity. A visual meter display of the integrated EMG was also provided. Self-regulation of frontal EMG was evident for all subjects within session 1. Throughout all sessions, EMG levels of 2-4 mu V were often attained. Trend analysis of EMG acquisition curves showed significant reduction in frontal tension across sessions for all but one subject. Frontal posttraining levels averaged 13.0 muV p-p. Parents or subjects, or both, reported subtle improvements in various speech and motor functions, a finding confirmed by objective postbiofeedback training evaluation. Only the 2 most severely impaired subjects, JA and DS, failed to improve significantly on the speech measures. All subjects improved significantly on those measures that tapped fine and gross motor skills. Collectively, these results indicate that EMG biofeedback training shows promise as an additional treatment modality in the habilitation of cerebral palsy patients.
言语和运动前生物反馈训练评估；额肌肌电图生物反馈训练，为期6周；言语和运动后生物反馈训练评估。受试者的额肌训练前平均水平为峰峰值28.9微伏。受试者的反馈包括与额肌肌电活动成比例变化的听觉信号（咔哒声）。还提供了肌电图积分的视觉仪表显示。在第1次训练期间，所有受试者的额肌肌电图自我调节都很明显。在所有训练过程中，肌电图水平经常达到2 - 4微伏。肌电图采集曲线的趋势分析表明，除一名受试者外，所有受试者在各训练阶段额肌紧张度均显著降低。额肌训练后平均水平为峰峰值13.0微伏。家长或受试者，或两者都报告了各种言语和运动功能有细微改善，这一发现得到了生物反馈训练后客观评估的证实。只有两名受损最严重的受试者JA和DS在言语测量方面没有显著改善。所有受试者在那些涉及精细和粗大运动技能的测量中都有显著改善。总体而言，这些结果表明，肌电图生物反馈训练有望成为脑瘫患者康复治疗中的一种辅助治疗方式。
