Hoffmann¹ originally suggested that the electrically induced stretch reflex in man is a monosynaptic one. Later Lloyd² proved in cats that the simple reflex twitch which resulted from muscle nerve stimulation is in fact monosynaptic, and, in 1951, Magladery and others³ confirmed this observation for the H reflex in man.

It soon became evident that even among normal human volunteers there is considerable variation of H reflex amplitude.^4,5 Moreover, the reflex in individual subjects varies spontaneously, as well as with changes in muscle length, tonic contraction, the Jendrassik maneuver, and post-tetanic potentiation (PTP). Attempts to correlate H reflexes with specific pathological conditions have met with limited success.^6-9 The H reflex is absent, or markedly reduced, when the myotatic reflex is itself absent due to a disorder of the reflex arc. An exception to this rule is spinal shock.¹⁰ Significant augmentation of the H . . . [Full Text PDF of this Article]
