Voluntary movements may be considered kinematic actions resulting from the neural control patterns that activate the motoneuron pools. One school of thought proposes that specific features of the intended kinematic trajectory such as the duration of acceleration are used by the central nervous system to plan muscle activation patterns. Our own experience suggests that it is the intended force trajectory that is directed by muscle activation patterns. Although under many circumstances these two approaches lead to indistinguishable behavior patterns, examples of movements that are incompatible with the former but not the latter approach are presented in this manuscript.
自主运动可被视为由激活运动神经元池的神经控制模式所产生的运动学动作。一种观点认为，中枢神经系统利用预期运动学轨迹的特定特征，如加速持续时间，来规划肌肉激活模式。我们自己的经验表明，是由肌肉激活模式来引导预期的力轨迹。尽管在许多情况下，这两种方法会导致难以区分的行为模式，但本文展示了一些与前一种方法不兼容但与后一种方法兼容的运动示例。
