Abstract
The changes in peak facilitation and slope of facilitation of the H-re flex were compared to the parameters of an isometric plantarflexion ta sk. The amplitude of the reflex was significantly greater for reflexes elicited within 50 msec. of the onset of soleus muscle activity. Neit her peak amplitude of the reflex nor slope correlated with rate of ris e of isometric force; however, they did show a modest relationship bet ween premotor time and reaction time.
