在自由猫行走过程中，许多后肢肌肉的肌电图活动与髋关节、膝关节和踝关节的角运动相关。伸肌群的活动较为均匀，而屈肌群不同功能群的活动则有差异。对主要伸肌活动开始的精确时间的观察表明，这不是由肢体中的受体（来自肌肉或皮肤）刺激产生的反射效应。假设基本活动是伸肌和屈肌的中枢程序性交替激活。一个可能的反射调节主要从LA传入的这一基本活动进行了讨论，特别注意的因素，可能阐明在髋关节一侧和膝盖和脚踝上的其他运动的差异。
During walking in unrestrained cats the electromyographic activity in many hindlimb muscles has been correlated with the angular movement in the hip, knee and ankle joints. The activity is rather uniform in the extensors but individual in different functional groups of flexor muscles. Observations on the precise timing of the onset of the main extensor activity suggest that it is not a reflex effect produced by stimulation of receptors (from muscle or skin) in the limb. It is assumed that the basic activity is a centrally programmed alternating activation of extensors and flexors. A possible reflex regulation mainly from la afferents of this basic activity is discussed with special attention given to factors that may elucidate the difference in movement at the hip on one side and the knee and ankle on the other.
