Hoffmann's reflex - Wikipedia
Hoffmann's reflex is a deep tendon reflex (spindle fibre) with a monosynaptic reflex pathway in Rexed lamina IX of the spinal cord, normally fully inhibited by descending input. On the other hand, the plantar reflex is more complicated and not a deep tendon reflex, and its pathway is both more complicated and not fully understood. [ 8 ]

The Hoffmann Reflex: Methodologic Considerations and Applications …
Originally described by Paul Hoffmann in 1910, 1 and later given his name, 2 the Hoffmann reflex (H-reflex) is an electrically induced reflex analogous to the mechanically induced spinal stretch reflex. The primary difference between the H-reflex and the spinal stretch reflex is that the H-reflex bypasses the muscle spindle 3 and, therefore, is a valuable tool in assessing modulation of ...
Hoffmann Reflex - an overview | ScienceDirect Topics
The Hoffmann (or H) reflex is one of the most studied reflexes in humans and is the electrical analogue of the monosynaptic stretch reflex. The H-reflex is evoked by low-intensity electrical stimulation of the afferent nerve, rather than a mechanical stretch of the muscle spindle, that results in monosynaptic excitation of α-motoneurons ( Fig ...
