Electromyographic feedback was compared with physical therapy for its relative effectiveness in training motor activity in patients with hemiplegia. A cross over design was used, so that each patient served as his own control. Strong reinforcement for attentional direction and for successful response to established criteria was used with both modalities. Electromyography through auditory and visual display was found effective in improving electromyographic activity, but more limited in training effective function as measured by active range of motion. In some cases it was counterproductive. Using an instrumental modality permits attention to only a limited number of motor elements involved in a motion, and is even more limited with respect to the interplay of activation and inhibition of those components. The activity of physical therapy, using tactile, proprioceptive, visual and communicative modalities, has the capacity for attending and drawing attention to many motor elements, as well as to the complexities of activation of some components concomitantly with the inhibition of others during the training process. Electromyographic feedback was felt to be especially useful in its ability to enhance figure-background discrimination and bypass possible areas of sensory obtundation.
将肌电图反馈与物理治疗在偏瘫患者运动活动训练中的相对有效性进行了比较。采用交叉设计，以便每位患者作为自身对照。两种治疗方式均对注意力方向及对既定标准的成功反应给予强烈强化。通过听觉和视觉显示的肌电图在改善肌电活动方面有效，但在以主动运动范围衡量的有效功能训练方面较为有限。在某些情况下，它甚至会产生相反的效果。使用仪器方式只能关注运动中有限数量的运动要素，在这些要素的激活与抑制的相互作用方面则更为受限。物理治疗通过触觉、本体感觉、视觉和交流方式进行，有能力关注并将注意力引向许多运动要素，以及在训练过程中一些要素激活同时其他要素抑制的复杂性。肌电图反馈因其增强图形 - 背景辨别能力及绕过可能的感觉迟钝区域的能力而被认为特别有用。
