Abstract:
Objective: We conducted a Meta-analysis to investigate the necessity of postural restrictions after manual reduction in the treatment of posterior canal benign paroxysmal positional vertigo (PC-BPPV). Methods: We searched PubMed, EBSCO, Proquest, Web of Science databases, Ovid, and screened eligible studies that investigated the effect of post-maneuver postural restriction in treating patients with PC-BPPV. Outcomes included the efficacy of treatment and recurrence. Meta-analysis was performed using Stata 15.0 software. Results: Studies of the single visit efficiency included 11 references, with a sample size of 1 733 cases. The Meta-analysis results showed that the difference in the efficacy between the postural restricted group and the non-postural restricted group in PC-BPPV patients was statistically significant(RR=1.12, 95%CI=1.07-1.18, P<0.001). There were 12 references included in the study on the total efficiency, with a cumulative sample size of 1763 cases. There was no statistically significant difference between the effect of postural restriction after manipulative reduction and that of simple manipulative reduction (RR=1.03, 95%CI=0.99-1.08, P=0.118). There were 5 references included in the study of recurrence rate, and the cumulative sample size was 659 cases. There was no statistically significant difference in the recurrence rate between the postural restricted group and the non-postural restricted group(RR=0.98, 95%CI=0.62-1.54, P=0.937). Conclusions: In comparison with non-postural restriction group, post-maneuver postural restriction after a single visit can improve the treatment effective rate of PC-BPPV and contribute to the improvement in the symptoms of patients in a short term. However, postural restrictions has no significant effect on the final prognosis of PC-BPPV, and it also has no significant effect on the recurrence.
