[Benign paroxysmal vertigo: comparison of 2 rehabilitation methods].

In case of non-self regression of Benign Paroxysmal Positional Vertigo (BPPV), reeducation is mandatory. Two reeducation protocols have been compared on 32 subjects with BPPV. Fourteen were handled by the classic habituation exercises, and 18 by the more recent Semont's manoeuvre. Moreover a specific rotatory nystagmus habituation has been investigated by caloric stimulation in Brunning III position. Semont's technique shows quicker and more efficient results. This manoeuvre doesn't provoke any habituation, in accordance with the hypothesis of mechanical dispersion of otoconia, based on the cupulolithiasis concept.
