Background An Egyptian normative database for ulnar nerve conduction studies (NCSs) considering the influence of age and sex is still absent. Objectives The aim of our work was to assess the normal variations of motor and sensory ulnar NCSs in a sample of normal Egyptian individuals at Zagazig University Hospitals. Methods This study was carried out at Zagazig University Hospitals on 110 individuals. Motor and sensory conduction studies of the ulnar nerve in the dominant hand were assessed. Results Motor latencies in male patients were longer than those in female patients and the difference was significant. No significant difference between male and female patients in any of the other ulnar nerve parameters was found. A significant positive correlation was found between age and motor latencies. Negative correlations were found between age and sensory amplitudes and with sensory conduction velocities. White collar workers had the slowest motor and sensory conduction velocities. Conclusion We conclude that age, sex, and occupation caused variability in ulnar NCSs in our studied group of normal Egyptians at Zagazig University Hospitals, but using the same reference data in patients of different ages and sex may result in inaccurate interpretation of ulnar NCSs, which is a common pitfall in our clinical practice.
