ICD-11 definition : Benign paroxysmal positional vertigo is defined as an abnormal sensation of motion
that is elicited by certain critical provocative physical positions of the patient
(e.g. becoming dorsal recumbent). The provocative positions usually trigger specific

to the part of the inner ear affected and the underlying pathophysiology.;
