Vibratory Perception Threshold and Motor Conduction Velocity in Diabetics and Non‐diabetics

The vibratory sense measured by biothesiometry was found to be correlated to age and sex in non‐diabetics. In diabetics the vibratory sense was correlated to the duration of the diabetes both on the upper and lower extremities. No difference was found between the sexes. It was possible to demonstrate a reduction of the vibratory sense already within the first year of diabetes in younger patients with a well‐defined onset of the disease. The same fact has been demonstrated previously with regard to the motor conduction velocity. In young diabetics motor and sensory nerve functions diminish in parallel.
