Single motor-unit (SMU) control was compared for three ambulatory cerebral-palsied and three neurologically unimpaired subjects. Both groups were similar in their abilities to produce a discrete whole muscle contraction, to isolate and maintain firing of a single motor unit, and to turn a unit on at a visual signal. Unit inter-spike intervals were very similar for both groups. However, the cerebral-palsied subjects showed a consistent inability to inhibit single motor-unit (or whole muscle) activity if the isolated unit had been firing for some time; normal subjects did not show a similar inability.
对三名患有脑性瘫痪的门诊患者和三名神经功能正常的受试者的单运动单位（SMU）控制能力进行了比较。两组在产生离散的整块肌肉收缩、分离并维持单个运动单位的放电以及根据视觉信号启动一个运动单位的能力方面相似。两组的单位峰间期非常相似。然而，如果分离出的运动单位已经放电一段时间，脑性瘫痪患者始终无法抑制单个运动单位（或整块肌肉）的活动；正常受试者则没有表现出类似的无能。
