Abstract
Wrist drop is a sign equally as treacherous as footdrop (see Chap. 16). Again, it has first to be established whether the weakness of elevation is peripheral or central. A simple and effective way of distinguishing between the two is to ask the patient to grasp the doctor’s hand firmly. In this movement, there is normally simultaneous contraction of the long extensor and flexor muscles of the forearm, in order to keep the wrist fixed in the stretched position which is required to permit a strong flexion of the fingers.
