癫痫发作率降低，加上随意运动抑制，伴随着感觉运动节律（SMR）的条件性增加，SMR 是罗兰皮质上出现的 12-14 Hz 节律。尽管 SMR 生物反馈训练已成功应用于人类各种形式的癫痫，但其在减少多动症方面的潜在用途仅限于少数以癫痫病史为重要特征的病例。本研究首次尝试探索该技术对独立于癫痫问题的运动过度问题的适用性。对多动儿童进行几个月的脑电图生物反馈训练的结果往往证实并扩展了之前的发现。 SMR 的反馈呈现取决于在没有 4-7-Hz 慢波活动的情况下 12-14-Hz 活动的产生。通过肌肉张力（下巴肌电图）的实验室测量和课堂上的整体行为评估来衡量，随着渐进式 SMR 训练，SMR 显着增加，并且与运动抑制增强相关。当训练程序相反并且反馈呈现取决于在缺乏 12-14 Hz 活动的情况下产生 4-7 Hz 时，运动抑制的相反趋势就会出现。尽管强调了这些结果的初步性质，但最近增加了受试者群体，以确定研究结果的有效性和普遍性，并将包括在停药后使用 SMR 生物反馈训练。
Reduced seizure incidence coupled with voluntary motor inhibition accompanied conditioned increases in the sensorimotor rhythm(SMR), a 12–14 Hz rhythm appearing over rolandic cortex. Although SMR biofeedback training has been successfully applied to various forms of epilepsy in humans, its potential use in decreasing hyperactivity has been limited to a few cases in which a seizure history was also a significant feature. The present study represents a first attempt to explore the technique's applicability to the problem of hyperkinesis independent of the epilepsy issue. The results of several months of EEG biofeedback training in a hyperkinetic child tend to corroborate and extend previous findings. Feedback presentations for SMR were contingent on the production of 12–14-Hz activity in the absence of 4–7-Hz slow-wave activity. A substantial increase in SMR occurred with progressive SMR training and was associated with enhanced motor inhibition, as gauged by laboratory measures of muscular tone(chin EMG)and by a global behavioral assessment in the classroom. Opposite trends in motor inhibition occurred when the training procedure was reversed and feedback presentations were contingent on the production of 4–7 Hz in the absence of 12–14-Hz activity. Although the preliminary nature of these results is stressed, the subject population has recently been increased to establish the validity and generality of the findings and will include the use of SMR biofeedback training after medication has been withdrawn.
