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 H-reflex (or Hoffmann's reflex) is a reflectory reaction of muscles after electrical stimulation of sensory fibers ( Ia afferents stemming from muscle spindles) in their innervating nerves (for example, those located behind the knee ).
M.H. Hoffman is associated with numerous companies. There is a bio on Hoffman in the 1929 and 1937-38 "Motion Picture Almanac." He studied painting, singing, and taught languages yet he is best remembered as a producer, director, and studio owner.

The H/M ratio is enhanced in spasticity but not in rigidity or in dystonia. Furthermore, in spasticity, H reflexes may appear in muscles in which they are not seen ordinarily (e.g., the small hand muscles).
Jan 1, 2024 · An H-reflex (also called a “Hoffmann reflex”) is the earliest response of a muscle to stimulation of large afferent fibers in the muscle nerve. If the nerve stimulation also excites large efferent fibers, the H-reflex is typically preceded by an M wave (or M response), which reflects excitation of the muscle by these efferents.

Apr 16, 2020 · The recent emergence of the novel, pathogenic SARS-coronavirus 2 (SARS-CoV-2) in China and its rapid national and international spread pose a global health emergency. Cell entry of coronaviruses depends on binding of the viral spike (S) proteins to cellular receptors and on S protein priming by host cell proteases.
