Movement-induced gain modulation of somatosensory potentials and soleus H-reflexes evoked from the leg II. Correlation with rate of stretch of extensor muscles of the leg

Abstract Attenuation of initial somatosensory evoked potential (SEP) gain becomes more pronounced with increased rates of movement. Manipulation of the range of movement also might alter the SEP gain. It could alter joint receptor discharge; it should alter the discharge of muscle stretch receptors. We hypothesized that: (1) SEP gain reduction correlates with both the range and the rate of movement, and (2) manipulation of range and rate of …
