Evidence for a Test of Dynamic Otolith Function Considered in Relation to Responses from a Patient with Idiopathic Progressive Vestibular Degeneration,

Abstract

A patient is described who possessed residual otolith function, but whose loss of canal function was complete for the horizontal and nearly complete for the vertical canals. A clear (but abnormal) nystagmus response was elicited during rotation about on Earth-horizontal axis, confirming the conclusion, based on animal experiments, that this response depends upon the otolith system. This test appears to measure dynamic otolith function and therefore provides a useful supplement to other vestibular tests. (Author)
