title: [Motor and staged sensory conduction velocities of the ulnar nerve in normal subjects].
abstract: Normative data of ulnar motor and orthodromic sensitive conduction velocities are performed at different levels on 68 (19 to 49 year old) adult population which included 35 men and 33 women. In fact, 102 ulnar nerves are tested, 51 nerves for female population and male population respectively. For motor conduction velocities, the ulnar nerve is stimulated at five levels: at the wrist level, below elbow, at the elbow, above elbow, and at the axillary point; the motor responses were picked up on the hypothenar muscles (surface electrodes). For orthodromic sensitive conduction velocities, the fifth finger is stimulated and the electrical activities are picked up by surface electrodes which are placed at the same points. The difference between the conduction velocities values measured on the below elbow/wrist segment and the above elbow/wrist segment proved to be satisfactory for the possible detection of a compression of the ulnar nerve at the elbow.
