Abstract:
Many researchers have established the influence of physiological factors as age, for the parameters of the study of the motor and sensitive conduction. The objective of this study was to analyze the influence of the variable age in the study of the motor and sensitive nervous conduction of the median and ulnar nerves. The data were collected from 92 volunteers: 61 women and 31 men. Their age was from 13 to 74 years old, with a mean of 36.3 years. Most of them were employees at Santa Casa de São Paulo. It was observed that a reduction in the velocity of sensitive and motor nervous conduction takes place with the age. This reduction is associated with a reduction in the amplitude of the evoked potential.
