Soleus reflex study

H-reflex - Wikipedia

★ ★ ★ ☆ ☆

H-reflex is analogous to the mechanically induced spinal stretch reflex (for example, knee jerk reflex). "The primary difference between the H-reflex and the spinal stretch reflex is that the H-reflex bypasses the muscle spindle, and, therefore, is a valuable tool in assessing modulation of monosynaptic reflex activity in the spinal cord."

1. Introduction. The Soleus Hoffmann reflex (H-reflex) is a monosynaptic reflex elicited by the stimulation of the tibial nerve, although a recent study suggests that polysynaptic components are also present (Burke, 2016).The H-reflex is evoked by the activation of group Ia afferent fibers from muscle spindles (Cramp et al., 2000), and its amplitude is determined by the excitability of spinal ...
