Objective:

To establish reference values of motor and sensory nerve conductions and late responses for the Electrodiagnostic Laboratory of Hospital Universitario San Ignacio.

Materials and Methods:

Sensory and motor nerve conduction studies were performed on 77 healthy volunteers between 18 and 65 years old, for a total of 154 analyzes, using a standardized technique for measurement.

Results:

Motor nerve conductions were performed measuring latency, amplitude and conduction velocity for the median, ulnar, tibial, and peroneal nerve. Sensory nerve conductions were performed measuring latency and conduction velocity for the median, ulnar, and sural nerve. A Shapiro-Wilk test was performed, finding that the amplitude parameters for sensory nerve conductions did not follow a normal distribution, so percentile analysis was performed. Only sex showed a statistically significant difference for the parameters of tibial nerve amplitude (p = 0.0099) being greater in women, and latency of the peroneal nerve (p = 0.0091) being greater in men.

Conclusion:

Normal parameters were established for motor and sensory nerve conductions and late responses for the Electrodiagnostic Laboratory of Hospital Universitario San Ignacio, which mostly correlate with the current reference data, with certain differences that could be related with height and sex. However, additional studies are required to enstablish this difference.
