最近，我们在组织复杂的多关节运动方面的知识取得了许多进展。我们在理解运动系统如何将外部目标位置信息转换为基于身体的坐标系中编码的运动命令方面已经取得了良好的开端。讨论的两种轨迹控制简化策略是响应特征的并行指定和平衡轨迹的编程。关于神经系统如何处理感官信息以规划和协助任务执行也获得了新的见解。最近的许多论文强调了感觉输入的前馈使用，这是通过外部世界、身体的物理设备和任务结构的模型来调节的。这些模型在反射和更高水平上发挥其影响，并允许准备轨迹的预测默认参数以及解决任务需求的策略。
There have recently been a number of advances in our knowledge of the organization of complex, multi-joint movements. Promising starts have been made in our understanding of how the motor system translates information about the location of external targets into motor commands encoded in a body-based coordinate system. Two simplifying strategies for trajectory control that are discussed are parallel specification of response features and the programming of equilibrium trajectories. New insights have also been gained into how neural systems process sensory information to plan and assist with task performance. A number of recent papers emphasize the feedforward use of sensory input, which is mediated through models of the external world, the body's physical plant, and the task structure. These models exert their influence at both reflex and higher levels and permit the preparation of predictive default parameters of trajectories as well as strategies for resolving task demands.
