Summary

The vestibulo-ocular reflex is the motor response of our eyes in the opposite direction to a translational or rotational movement of our head. The post-rotational nystagmus test (PRN) assesses the integrity of this reflex, thus assessing the perception of the vestibular system. The duration of this reflex after administering this test has been widely studied in children from 2 months to 12 years and 11 months of age. However, there is a knowledge gap from that age that the present study seeks to address.

DIAGNOSTIC_TEST

Post-rotatory nystagmus test

The test is administrated with the person sit down with cross legs at a rotatory board, with the head positioned by the examiner in 30° of forward flexion. The position was maintained by the administration of the test. The administration consist in two administrations separate by one minute. Each administration consist in rotate the person 10 times in 20 seconds (the first 10 rotations in a counterclockwise direction in 20 s and the second 10 rotations in a clockwise direction in 20 s). After each administration the examiner counts the duration of the reflex in seconds.
