In order to investigate the residual tension of muscle in cerebral palsied (CP) children (adults) and the effect of EMG feedback on its relaxation processes, 5 normal children and 15 CP children, including one adult, were asked to flex their elbows gradually, then increase the tension with full flexion, and finally relax as quickly as possible under three conditions: pre-feedback, feedback, and post-feedback. Under the feedback condition, a meter display was provided. Results were as follows: (1) All except one in the CP group showed more residual tension than the normals at the pre-feedback condition. (2) Under the feedback condition, the time to relax was shortened significantly in the CP group. (3) The CPs could be classified into following four types by the influence of EMG feedback. (a) Type A (N = 2) showed no change. (b) Type B (N = 9) improved. (c) Type C (N = 1) improved in the latter half of the feedback condition, though it increased tension in the first half. (d) Type D (N = 2) increased conversely under the feedback condition.
为了研究脑瘫（CP）儿童（成人）肌肉的残余张力以及肌电图反馈对其放松过程的影响，选取了5名正常儿童和15名CP儿童（包括1名成人），要求他们在三种条件下：反馈前、反馈中和反馈后，逐渐弯曲肘部，然后在完全弯曲时增加张力，最后尽快放松。在反馈条件下，提供一个仪表显示。结果如下：（1）CP组中除1人外，所有人在反馈前条件下的残余张力均高于正常儿童。（2）在反馈条件下，CP组的放松时间显著缩短。（3）根据肌电图反馈的影响，CP患者可分为以下四种类型。（a）A型（N = 2）无变化。（b）B型（N = 9）有所改善。（c）C型（N = 1）在反馈条件的后半段有所改善，尽管在前半段增加了张力。（d）D型（N = 2）在反馈条件下反而增加。
