我们描述了一个模型的快速，单关节运动的调节，平衡点假设的基础上。肢体运动遵循独立调节的神经肌肉变量的恒定速率变化。独立调节的变量被暂时确定为阈值的长度敏感反射的每个参与肌肉。我们使用该模型来预测与运动执行条件的变化相关的EMG模式，具体而言，运动时间，速度，幅度和肢体惯性矩的变化。该方法为双策略假设提供了一个理论神经框架，该假设认为某些动作是两种基本策略之一的结果，速度敏感或速度不敏感。该模型是先进的作为一种替代模式强加模型的基础上明确的时间和幅度的信号，明确表现在EMG模式的明确规定。
We describe a model for the regulation of fast, single-joint movements, based on the equilibrium-point hypothesis. Limb movement follows constant rate shifts of independently regulated neuromuscular variables. The independently regulated variables are tentatively identified as thresholds of a length sensitive reflex for each of the participating muscles. We use the model to predict EMG patterns associated with changes in the conditions of movement execution, specifically, changes in movement times, velocities, amplitudes, and moments of limb inertia. The approach provides a theoretical neural framework for the dual-strategy hypothesis, which considers certain movements to be results of one of two basic, speed-sensitive or speed-insensitive strategies. This model is advanced as an alternative to pattern-imposing models based on explicit regulation of timing and amplitudes of signals that are explicitly manifest in the EMG patterns.
