Efficacy of postural restriction in preventing recurrence of Benign Paroxysmal Positional Vertigo: a randomized controlled clinical study

Objective To evaluate the effect of postural restriction in preventing recurrence of Benign Paroxysmal Positional Vertigo(BPPV).Methods A total of 217 unilateral posterior semicircular canal BPPV patients were diagnosed clearly and divided into two groups randomly:104 caes(observation group)were demand postural restriction(head up 45 degrees for 72 hours,but did not restricted sleeping posture or departure from bed)after Epley maneuver,while 114 case(control group)could freely sleep.Demographic data,concomitant diseases and betahistine mesylate treatment were recorded.All patients were follow-uped at 72 hours after the Epley maneuver at outpatients of our hospital.A induced vertigo by position change or positional nystagmus were defined as recurrence of BPPV.Results There was no statics defferrence between two groups for base line data.After 72 hours of Epley maneuver,BPPV recurrence rates was 21.2%and 41.6%for observation group and control group,respectively(P<0.01).Odds ratio of postural restriction for BPPV recurrence was 0.377(95%CI 0.207~0.687).Conclusion Head up 45 degrees for 72 hours after Epley maneuver was helpful for preventing BPPV early recurrence.
