Voluntary actions are controlled by the synaptic inputs that are shared by pools of spinal motor neurons. The slow common oscillations in the discharge times of motor units due to these synaptic inputs are strongly correlated with the fluctuations in force during submaximal isometric contractions (force steadiness) and moderately associated with performance scores on some tests of motor function. However, there are key gaps in knowledge that limit the interpretation of differences in force steadiness.
自主行动由脊髓运动神经元池共享的突触输入控制。由于这些突触输入，运动单位放电时间的缓慢共同振荡与次最大等长收缩期间的力量波动（力量稳定性）密切相关，并且与一些运动功能测试的表现评分中度相关。然而，知识上存在关键空白，限制了对力量稳定性差异的解释。
