简要总结
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.
详细描述
The vestibulo-ocular reflex (VOR) 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. This system has an important role in our balance, stabilization of the visual field when our head moves, awareness of the position of our head in space, postural control and functions of the Autonomous Nervous 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. This article aims to explore the use of the PRN test for adolescent and adults, to prove if the duration of the VOR is longer in these population than in children. It will be also recollected personal data to study whether exposure to vestibular input influences its reactivity and perception.

结局指标
主要结局
Duration of vestibular-ocular reflex after the administration of nystagmus post-rotatory test in adolescent and adult population
时间窗: End of the nystagmus post rotatory test and end of the vestibular-ocular reflex
The post rotatory nystagmus test evaluates the duration of the vestibular-ocular reflex: how long its lats gives information about the perception of vestibular system. This reflex reflects the role of the vestibular system in ocular mechanisms (Mailloux et al., 2014). It is administered twice: clockwise and counterclockwise.After the administration the physiologic nystagmus appears, it is our vestibular-ocular reflex, and the examiner has to register the duration of it.
