A Review on Locomotor Training after Spinal Cord Injury: Reorganization of Spinal Neuronal Circuits and Recovery of Motor Function

Figure 3

Functional reorganization of presynaptic inhibition of soleus Ia afferents after locomotor training in SCI. (a) Schematic diagram of the neuronal pathway of presynaptic inhibition of soleus Ia afferents. In this paradigm, presynaptic inhibition of soleus Ia afferents is induced by a conditioning afferent volley following common peroneal nerve stimulation at long conditioning-test (C-T) intervals. (b) Mean amplitude of the conditioned soleus H-reflex as a percentage of the unconditioned H-reflex recorded at each C-T interval tested before and after locomotor training from the right leg, grouped per AIS, in the seated position. indicate statistically significant differences of the conditioned H-reflexes recorded before and after locomotor training. Data adopted and modified from [72].
