Instrumental fore-leg movements (pedal pressing) were studied in the course of recovery of motor functions after section of the posterior columns and the spino-cervical tract at the cervical level. Recovery of supporting-locomotor functions reached a high level. Instrumental reactions connected with inborn forms of motor activity (running etc.) were being restored parallel to the locomotion restoration. Complex instrumental movements were restored slower and didn't reach a high degree of accuracy. A more simple instrumental movement (pressing on the open pedal) had a more rapid and more complete recovery. It is concluded that the possibilities of substitution of different channels, transmitting afferent somatic impulses to the sensorimotor cortex, are very limited for elaborated instrumental movements.
在颈段后柱和脊髓颈段束切断后运动功能恢复过程中，对前肢的工具性运动（踩踏板）进行了研究。支撑 - 运动功能的恢复达到了较高水平。与先天运动形式（奔跑等）相关的工具性反应在运动恢复的同时也得以恢复。复杂的工具性运动恢复较慢，且未达到高度的准确性。较简单的工具性运动（踩开放踏板）恢复得更快且更完全。得出的结论是，对于精细的工具性运动而言，将传入躯体冲动传递至感觉运动皮层的不同通道的替代可能性非常有限。
