[Phobic orthostatic insecurity].

Background And Objectives: The authors attempt to expand knowledge about a subjective balance disorder they have called phobic orthostatic insecurity, a condition representing the second cause of medical visits (22.3 %) to their ENT and neuro-otology clinic, and attempt to identify relationships with similar conditions described in psychiatry (agoraphobia, somatoform vertigo, and space-phobia) and in neurology (phobic postural vertigo). They also propose a simple diagnostic method and present their therapies and results.
