[Diagnosis and treatment of benign paroxysmal positional vertigo with manual and motorized chairs - Indication and...

Benign paroxysmal positional vertigo (BPPV) is the most frequent cause of episodic vertigo or dizziness. While this diagnosis can be made reliably in most cases by use of targeted history taking followed by provocation maneuvers on the examination couch and subsequent repositioning maneuver, these maneuvers may not be applicable in a subgroup of patients with pre-existing conditions such as musculoskeletal or neurologic disorders. At the same time, part of patients treated on the examination couch will not respond to the repositioning maneuvers. The use of a manual or motorized turntable thus extends both the diagnostic and therapeutic options in BPPV. Thus, it enables patients with disabilities that do not tolerate classic maneuvers on the examination couch access to the required diagnostic procedures and - if needed - provides targeted treatment as well. Furthermore, turntables extend both the diagnostic and the therapeutic spectrum, offering a broader range of repositioning maneuvers in unclear or treatment-refractory cases. In this narrative review potential indications are described and evidence for using turntables in the diagnosis and treatment of BPPV on the turntable is discussed.
