Wartenberg Thumb Reflex
Forceful flexion of the fingers at the distal IP joints produces (Adduction, flexion, and opposition of the thumb) INSTEAD of a normal response of abduction and extension.
This is a manifestation of a corticospinal tract lesion and has been called the upper extremity equivalent of Babinski’s plantar sign.
This is distinct from unrelated Wartenberg sign in ulnar neuropathy.
