Hoffman's sign. Even in this specific case, accompanied by a clonus outline (rhythmic contractions). The median nerve acts both as an afferent and efferent pathway and the spinal root is C5-6. To search for this signal: 1) Hold the patient's middle finger. 2) Ask the patient to relax the hand. 3) Now strike lightly on the nail of the terminal phalanx of the flexed middle finger. 4) Observe the flexion of the thumb and index finger.
