A computer program was developed to analyse the relative amount of EMG activity in an agonist-antagonist pair of muscles while subjects performed voluntary flexion-extension movements at the wrist to track a visual target. The data were presented to the subjects in the form of a vector display, the angle and length of which was determined from calculation of EMG power in the two muscles. This new approach to EMG biofeedback was evaluated in two hemiplegic patients and three patients with cerebellar incoordination. Over a training period of several weeks, all the subjects were able to modify the pattern of EMG activity in the muscles to reduce the amount of inappropriate coactivation of flexors and extensors and to produce more sustained and regular activation of individual muscle groups.
开发了一种计算机程序,用于分析在受试者进行腕部自愿屈伸运动以追踪视觉目标时,一对拮抗肌中肌电图(EMG)活动的相对量。数据以矢量显示的形式呈现给受试者,其角度和长度由两块肌肉中EMG功率的计算确定。在两名偏瘫患者和三名小脑共济失调患者中对这种新的肌电图生物反馈方法进行了评估。在为期数周的训练期间,所有受试者都能够改变肌肉中肌电图活动的模式,以减少屈肌和伸肌不适当的共同激活量,并使各个肌肉群产生更持续和规律的激活。
