H-reflex of single motoneurones in man


Play all audios:

ABSTRACT As early as 1918 Hoffmann described how electrical stimulation of the tibial nerve in man evokes, in addition to a direct motor response in the calf muscles, another well


synchronized motor response at a latency of about 30 ms1. He concluded that this later response was identical with the myotatic reflex, because it had the following characteristics : (1) it


appears only in the muscles supplied by the stimulated nerve; (2) it can be evoked by shocks which are subliminal for motor axons and it tends to be blocked at stronger stimulus strengths;


(3) it is conducted in afferent fibres of high velocity and its central delay is short enough to indicate a monosynaptic pathway; (4) it is facilitated by a voluntary contraction of the


muscle involved and obliterated by a contraction of its antagonist. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution
