The Hoffman sign is an abnormal reflex response that consists of flexing the fingers of the hand when pressing the nail of the middle finger Although it is generally associated with pathologies such as pyramidal syndrome, it can occur in healthy people who have heightened reflexes (which is called hyperreflexia) Your neurological finger tapping reflex, also known as the Hoffman sign, is used to identify damage to the central nervous system and monitor recovery from brain injury This reflex is triggered by stimulated neurons triggering a cascade of voluntary skeletal muscle contractions known as evoked muscle accidents (EMCA)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 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
