Condition Intervention
Unspecified Disorder of Vestibular Function, Bilateral
Behavioral: vestibular stimulation

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Basic Science
Official Title: Biological Rhythms and Vestibular System

Further study details as provided by University Hospital, Caen:

Primary Outcome Measures:
  • 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

Estimated Enrollment: 96
Study Start Date: April 2013
Estimated Primary Completion Date: April 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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

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
