Exercise therapy for positional vertigo.

We present a common cause of vertigo, benign positional paroxysmal vertigo (BPPV), and its history, diagnosis, and therapy. BPPV is suggested by history, readily diagnosed by office examination, and cured by appropriate exercise therapy. Since the condition is so common and often unrecognized, physicians are encouraged to consider BPPV as a possible cause of treatable dizziness.
