Effect of vibration on semicircular canal during whole body vibration

Chronic exposure to whole body vibration can affect the lumbar spine, the gastrointestinal system, the peripheral veins and the vestibular system.The semicircular canals (SSC), as a part of vestibular system, are responsible for sensing angular head motion in three-dimensional space and for providing neural inputs to the central nervous system.In this paper, the influence of random vibration on the body of the subject at an excitation of 1.0 m/s 2 and 1.5 m/s 2 was investigated.The 3D geometry of the SSC canal was obtained using DICOM CT images.Simulation of endolymph flow is carried out.Numerical analysis provides the pressure generated on SSC.Response of cupula is obtained for various rotational velocities of head.Variation of pressure generated on cupula and response of cupula is studied and reported.
