[Repositioning maneuver for self-performing by patients in cupulolithiasis of horizontal canal BPPV]

The aim of the study is to evaluate the efficiency of the new repositioning maneuver for patients with horizontal canal cupulolithiasis benign paroxysmal positional vertigo (BPPV) to perform independently at home between doctor's sessions.

28 patients with isolated horizontal canal cupulolithiasis BPPV were enrolled. In all of them treatment with Gufoni maneuver was not successful after first session. They were divided in M«-» group (17 patients), M«-» group (11 patients). M«-» group performed forced prolong prositionig on the side with less dizziness between sessions. M«-» group performed forced prolong prositionig on the side with less dizziness and 3-5 repetitions of new repositioning maneuver 2-3 times a day between sessions. Repositioning maneuver consists of head shaking, then moving to one side-lying position with maintaining it until dizziness stops and resuming the upright sitting position, then without a pause performing head shaking and moving to the other side-lying position with maintaining it until dizziness stops and resuming the upright sitting position. The patients visited doctor once a week. Before treatment and 1 week after treatment dizziness handicap inventory (DHI) was administrated.

After 2 and 3 weeks of treatment more patients in M«-» group than in M«-» group were cured (p<0.05). After 4 weeks of treatment the number of recovered patients did not significantly differ in both groups. After 1 week of treatment according to DHI scores in M«-» group there were less patients with mild dizziness and more patients with moderate dizziness than in M«-» group (p<0.05).

Recovery from horizontal canal cupulolithisis BPPV could be achieved at an early date with self-performing of new repositioning maneuver. Patient-perceived disability in persisting horizontal canal cupulolithiasis could be less if the new repositioning maneuver is performed.
