TEP depression by soleus muscle spindle group Ia afferent stimulation before and after 40 minutes of transspinal stimulation. Waveform averages of TEPs from one representative subject under control conditions and following transspinal conditioning stimulation before (green lines) and after (red lines) 40 min of transspinal stimulation. All traces are shown as captured, without subtraction, to counteract summation between soleus H-reflex and soleus TEP at C-T intervals when this phenomenon is observed. Circled traces indicate potentiation of TEP depression by soleus muscle spindle group Ia afferent conditioning stimulation after 40 min of transspinal stimulation.
