Normal values for the two-point discrimination test.

A 2-point discrimination study was conducted with 112 normal children, ages 2-13 years. The goal was to determine the age at which children can reliably cooperate in performing the 2-point discrimination test and to discover the normal values on the fingertips and feet for different ages, as well as to study the changes in these values with age. It was found that from age 6 years and older all children could perform the test and that discrimination ability improved with age, but was only of statistical significance for the feet parameters.
