findings surface electrodes were used for studying both median & ulnar (recorded at ADM & 1 dorsal interosseous muscles ) nerves of right upper limb,motor, sensory & Late reponses. EMG of right abductor pollicis bervis, abductor digiti minimi, & 1 dorsal interosseous muscles was done. CONCLUSIONS these electrophysiological finding are compatible with: Incomplete lesion of deep branch of right uluar never at the site of trauma at right hand. Right carpal tunnel synderome affecting motor (mild)& sensory fibers (mild). NO pronator teres syndrome. NO evidence for proximal entrapment (cervical) on right for median never. NO evidence for proximal entrapment (cervical) on right for ulnar never.
