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

Figure 2

Functional reorganization of homosynaptic depression after locomotor training in SCI. (a) Schematic diagram of the soleus H-reflex homosynaptic depression exerted at Ia-motoneuron synapse with repetitive activation of Ia afferents. (b). Nonrectified waveform averages of soleus H-reflexes recorded at different stimulation frequencies from one AIS B patient before and after locomotor training for both legs. The soleus H-reflex amplitude exhibited a strong stimulation frequency-dependent depression after locomotor training. Data adopted and modified from [72].
