Comparison of sensory latencies of the median nerve at the carpal tunnel among juveniles and adults.

Five hundred and ninety-three juveniles and adults were studied to determine if there was an age-related trend in the occurrence of sensory nerve conduction latencies of the median nerve at the carpal tunnel. Latencies were found to increase with increasing age in both the dominant and nondominant hands of the subjects. A significant and positive correlation was found between the latencies of both hands, indicating that an increased value in one hand is likely to be associated with an increased value in the other. Among the adults, the latencies were found to be consistently greater for the dominant hand.
