The moving two-point discrimination test: Clinical evaluation of the quickly adapting fiber/receptor system

As the Weber test evaluates the slowly adapting fiber-receptor system (constant touch), the "moving two-point discrimination test" evaluates the innervation density of the quickly adapting fiber-receptor system which mediates the perception of touch stimuli moving across the hand. Results with this test in 39 hands used as controls and in 63 patients with nerve injuries show it to be a simple, quick, and valid diagnostic tool in nerve compression syndromes and nerve lacerations and an accurate prognosticator and monitor during sensory reeducation following nerve repair.
