Resumen
Introduction. Benign Paroxysmal Positional Vertigo (BPPV) of the posterior semicircular canal is a chronic disease severely affecting quality of life. Repositioning Maneuvers is a way of relieving it, consisting of a series of sequential exercises of the head into 4 positions. The purpose of the maneuver is to reposition the otoliths from the posterior semicircular canal inside the lobby to the sites where they migrated to stop producing vertigo. Each position has to remain for approximately 30 seconds. The maneuvers have proven to be highly effective in the short term. The results are measurable by means of a questionnaire known as Dizziness Handicap Inventory (DHI). Objectives: To measure the impact of repositioning maneuvers on disability in patients with BPPV of posterior semicircular canal, using the DHI. Methods: A comparative study using T-test for paired samples where each patient is his own control was used in a sample of 20 patients diagnosed with BPPV of posterior semicircular canal were studied and treated with repositioning maneuvers. Results were evaluated by DHI and ran in day 1, day 7 and 30 after Repositioning maneuvers performed. Results: Females are most affected by BPPV in a ratio of approximately 2.1. The degree of disability was measured by the result of DHI, which shows for days 1, 7, and 30 an average of 50.4, 30.4 and 24.2 respectively. The scale with a higher score were days 1 and 7 then showing a marked decreased on day 30. Mean results were the 20, 2 and 9.5 respectively. The differences between the means were statistically significant. (P = 0.000062, 0.000002 and 0.037010). Conclusions: BPPV affects the quality of life. Repositioning maneuvers are statistically significant to reduce the disability caused by BPPV of the posterior semicircular canal so, it is important to quickly see a specialist when first signs manifest and that way avoid increasing the total disability associated with vertigo.
