Reference values were determined for standard measurements of amplitude and conduction velocity for the median, ulnar, sural, and perineal nerves in a large occupational cohort of healthy white male workers. The data were collected as part of a cross sectional medical study. There were 394 men in whom upper limb nerve function was evaluated and 392 men in whom lower limb nerve function was evaluated. Subjects ranged in age from 31 to 77 years. Predicted mean amplitude and conduction velocities for each nerve and age group were tabulated. The initial covariates included in each model were finger or toe temperature, lifetime alcohol consumption, lifetime cigarette consumption, height, weight and age group. With the exception of age and temperature, the variables which were considered a-priori to cause significant diminution of nerve function generally had small or inconsistent influence on the mean predicted value for any test parameter. Therefore, data for age and limb temperature were minimal requirements for measurements of amplitude and conduction velocities.
