The multi-channel system of the segmental muscle stretch reflex arc is modelled as an arrangement of two or three parallel "component" loops coupled to each other at spinal and at muscle level. Such a model is thought to be more realistic than the usually adopted representation of the stretch reflex as a single negative feedback loop. Anatomical and physiological data were taken from the literature for an extensive simulation of the compound system with special reference to the problem of its stability. Particular emphasis was put on the question of which kind of central (spinal) connectivity is appropriate to best reduce the risk for instability which arises easily in certain system configurations. This paper describes the system and presents simple introductory computations apt to demonstrate the problems the physiological system has to cope with.
节段性肌肉牵张反射弧的多通道系统被建模为在脊髓和肌肉水平相互耦合的两个或三个平行“组件”环路的排列。这种模型被认为比通常采用的将牵张反射表示为单个负反馈环路的模型更现实。从文献中获取解剖学和生理学数据，以对复合系统进行广泛模拟，特别关注其稳定性问题。特别强调了哪种类型的中枢（脊髓）连接性最适合降低在某些系统配置中容易出现的不稳定风险这一问题。本文描述了该系统，并给出了简单的介绍性计算，以说明生理系统必须应对的问题。
