Tromner Sign on Physical Exam

Tromner sign indicates pyramidal release.  The Tromner sign is flexion of the thumb and index finger in response to tapping or flicking the volar surface of the distal phalanx of the middle finger held partially flexed between the examiner’s finger and thumb.  It is an established neurological sign for pyramidal response in the upper extremity, and has been recognized as an alternative of Hoffmann’s sign
