Group comparisons of the heteronymous modulation of soleus H reflex in 15 hemiparetic and 15 healthy participants Mean peak facilitation and maximal inhibition of soleus H reflex induced by the stimulation of femoral nerve (expressed as a % of the control reflex) observed from −10 to 40 ms ISI (A).

<p>Mean duration of the facilitation calculated as the difference between the latest and the earliest ISIs at which it was observed (B). Vertical bars = 1 SEM. Asterisks represent significant difference in modulation between the paretic side, the non-paretic side of stroke participants and the tested side of control participants (* p≤0.05; ** p≤0.01).
