肌肉传入的反馈对于运动在不断变化的外部条件下发挥作用是必不可少的。在这篇文章中，我们回顾了在减少和行走猫的准备中，传入反馈在使运动活动适应感觉输入的瞬时和更持续的变化中所起的作用。许多关于肌肉传入运动调节的工作都集中在对站姿时相活动的调节上。站立阶段伸肌的本体感觉反馈确保腿部在负重时不会进入摆动状态，伸肌活动的幅度足以支撑。在站立阶段结束时，屈肌的本体感觉反馈有助于启动行走的摆动阶段。最近有证据表明，肌肉传入反馈对摆动阶段屈肌活动的大小和持续时间也有影响。运动过程中伸肌和屈肌活动的大小和持续时间的调节是由脊髓中的单突触、双突触和多突触肌肉传入通路介导的。除了在行走过程中允许运动输出的快速适应外，来自肌肉本体感受器的传入反馈也参与了对行走系统生物力学或神经肌肉特性变化的长期适应。
Feedback from muscle afferents is essential for locomotion to be functional under changing external conditions. In this article, we review the role of afferent feedback in adapting locomotor activity to transient and more sustained changes in sensory input in reduced and walking cat preparations. Much of the work on muscle afferent regulation of locomotion has focused on the regulation of stance phase activity. Proprioceptive feedback from extensor muscles during the stance phase ensures that the leg does not go into swing when loaded and that the magnitude of extensor activity is adequate for support. Proprioceptive feedback from flexor muscles towards the end of the stance phase facilitates the initiation of the swing phase of walking. Evidence that muscle afferent feedback also contributes to the magnitude and duration of flexor activity during the swing phase has been demonstrated recently. The regulation of the magnitude and duration of extensor and flexor activity during locomotion is mediated by monosynaptic, disynaptic, and polysynaptic muscle afferent pathways in the spinal cord. In addition to allowing for rapid adaptation in motor output during walking, afferent feedback from muscle proprioceptors is also involved in longer-term adaptations in response to changes in the biomechanical or neuromuscular properties of the walking system.
