Brief Summary:
The purpose of this study is to study the relationship between the vestibular system and chronobiology

Condition or disease Intervention/treatment
Unspecified Disorder of Vestibular Function, Bilateral Behavioral: vestibular stimulation

Detailed Description:

The purpose of this study is to study the relationship between the vestibular system and chronobiology.

Two parts will be performed. In the first one patients with bilateral vestibular areflexia will be compared to control subjects.

In the second the effect of vestibular stimulation on circadian rhythms will be evaluated

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 96 participants
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Biological Rhythms and Vestibular System
Study Start Date : April 2013
Estimated Primary Completion Date : April 2016

Arm Intervention/treatment
No Intervention: control
Control without vestibular stimulation
No Intervention: Bilateral areflexia
Patient with vestibular bilateral areflexia
No Intervention: Areflexia controls
Controls for patients with vestibular bilateral areflexia, matched in sex and age
Experimental: vestibular stimulation
Subjects submitted to vestibular stimulation in order to improve circadian rhythms
Behavioral: vestibular stimulation
Physical activity and vestibular stimulation will be used in order to improve circadian rhythms

Primary Outcome Measures :
  1. Measurements of vestibular reflexes (ocular and spinal) and circadian rhythms of biological functions. [ Time Frame: 3 years ]
    Gain of vestibular ocular reflex Amplitude of vestibular spinal reflex Amplitude and phase of temperature circardian rhythms
