Abstract: A base section supports a revolution section. The revolution section supports a tilting section. The tilting section supports a seat section. The seat section includes a seat, a seat back and a step. The seat back has a restraining section. The restraining section includes an occipital region retainer and a temple retainer. Subject is seated with its occipital region and temples restrained by the restraining section. The head of subject is tilted on one side down from a head's horizontal plane in the Reid stereotaxic coordinate system to place one of left and right otolith organs within the head's horizontal plane. In this tilted position, different liner acceleration stimuli are applied to left and right otolith organs, respectively, for independent function tests of the left and right otolith organs.

Abstract: A therapeutic method completely opposite to the known basic therapeutic policy including restriction of water and salt intake, which has been hitherto designated as the therapeutic method for Meniere's disease, and is a therapeutic method for endolymphatic hydrops associated diseases by performing water intake therapy for the patient with strongly suspected Meniere's disease from the initial stage of disease. For preventing vertiginous attack and hearing loss by performing patient compliance instruction for proper intake of water and maintaining plasma AVP at low level: sufficient water intake and short term administration of osmotic diuretic in the patient are performed; plasma osmotic pressure is maintained at the lowest limit of the normal level; secretion of AVP from the pituitary grand is minimized; proper activity of AQP2 in the inner ear is maintained; influent of water into the endolymph is decreased; and prevention of vertiginous attack and improvement of hearing are performed.
