Training-Specific Neural Plasticity in Spinal Reflexes after Incomplete Spinal Cord Injury

Figure 3

Changes in reflex excitability during walking varied with training type. The cutaneomuscular reflex (CMR) during 8 bins in the walking cycle, averaged across participants (), are shown for the soleus (a)(i) and tibialis anterior (b)(i) muscles before and after Endurance Training. Significant differences in post hoc comparisons are indicated with ★. Average EMG corresponding to the bin numbers during unperturbed walking trials are shown in (a)(ii) and (b)(ii). Error bars represent one standard deviation. ST: stance phase (solid bars); SW: swing phase (open bars). (a)(iii) Maximum (Max) inhibition of the SOL CMR before and after Endurance Training is shown for each participant, with the group mean superimposed.
