Hoffmann's Reflex on Physical Exam The Hoffmann's reflex itself involves loosely holding the middle finger and flicking the fingernail downward, allowing the middle finger to flick upward reflexively. A positive response is seen when there is flexion and adduction of the thumb on the same hand. A positive Hoffmann’s reflex and finger jerks suggest hypertonia, but can occur in healthy individuals, and are not useful signs in isolation. #Hoffmanns #Reflex #Sign #PhysicalExam #clinical #neurology #UMN #video #Pyramidal
