Answer

Age is another important factor to consider during electrodiagnostics. Young children have slower conduction velocities because the process of myelination of peripheral nerves becomes completed between the ages of 3 and 5 years. Additionally, conduction velocities begin to decrease after the age of 60 years at a rate of 0.5 to 4.0 m/s/decade.
