Peripheral nerve conduction velocity in normal infants and children.

Maximum motor conduction velocity of the median, ulnar and peroneal nerves and maximum sensory conduction velocity of the median nerve have been studied in 635 children, below 12 years of age, free from peripheral nervous system disease. The children fell into four age-group: from 0 to 1 year; from 1 to 3 years: from 3 to 6 years; from 6 to 12 years. No normal values were recorded for the sensory conduction velocity of the median nerve under the age of one year. The motor conduction velocity values significantly rise for the median and ulnar nerves up to 1 year, for the peroneal nerve up to 3 years. The sensory conduction velocity values of median nerve increase significantly up to 6 years.
