Dynamics of the H Reflex and Tonic Activity in the Human m.Soleus at a Voluntary Movement of the Upper Limb

In tests on healthy volunteers, we examined the effects of voluntary flexion of the elbow joint on the magnitude of the H reflex recorded from the ipsilateral m. soleus and on tonic EMG activity of this muscle. The H reflex was subjected to two-phase modulation; a period of facilitation lasting up to 300 msec was replaced by subsequent long-lasting… CONTINUE READING
