Ulnar nerve lesions may occur at different sub-locations at wrist and may involve various branches of the nerve. Standard neurophysiological studies are generally insufficient in revealing these lesions. Demonstration of conduction block and/or focal slowing of nerve conduction is the most definitive electrodiagnostic evidence for the localization of segmental demyelination. Short-segment incremental study (SSIS) is a sensitive technique for detecting the ulnar neuropathy at the wrist (UNW).
