Introduction: The Hoffmann reflex, or H-reflex, which is the electrical equivalent of the myotatic reflex, is a very valuable tool for evaluating the reflex pathway and for investigating the mechanisms that regulate the intensity of its response. Yet, the complex interaction of the H-reflex circuit with other neural components requires a tight-fit recording protocol.

Hoffmann's reflex (Hoffmann's sign, sometimes simply "Hoffmann's", also finger flexor reflex) is a neurological examination finding elicited by a reflex test which can help verify the presence or absence of issues arising from the corticospinal tract.It is named after neurologist Johann Hoffmann. Usually considered a pathological reflex in a clinical setting, the Hoffmann's reflex has also.

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.

The mean age of the participants was 27 years old with the youngest participant being 16 and the eldest 78.

The German neurologist Johann Hoffman first postulated this sign. It was described by his assistant Hans Curschmann in 1911 and has become a standard part of the common neurologic exam.[1] The Hoffman sign is an involuntary flexion movement of the thumb and or index finger when the examiner flicks the fingernail of the middle finger down. The reflexive pathway causes the thumb to flex and.

A positive Hoffman's sign in the normal patients is more commonly found in those who are naturally hyper-reflexive. A positive Hoffmann's sign is a worrisome finding of a disease process if its presence is asymmetrical, or has an acute onset. Hoffman's reflex is a deep tendon reflex, a monosynaptic reflex pathway in of the spinal cord.

The monosynaptic stretch reflex, or sometimes also referred to as the muscle stretch reflex, deep tendon reflex, is a reflex arc that provides direct communication between sensory and motor neurons innervating the muscle. This reflex begins inside the muscle spindle of the muscle, which detects both the amount and rate of muscle stretch. When the muscle experiences a stretch stimulus, sensory.

Hoffmann's Sign. H.W. Sander, J.A. Williams, in Encyclopedia of the Neurological Sciences (Second Edition), 2014 Abstract. Hoffmann's sign (also referred to as Hoffmann's reflex) (C7, C8, and T1; median nerve) is a variation on the technique of eliciting finger flexor reflex.If the reflexes are hyperactive, the snapping of the middle finger may be followed by flexion and adduction of the thumb.
