Effect Of Brandt-Daroff Habituation Training Combined With Repositioning Chair On Benign Paroxysmal Positional Vertigo

ObjectiveTo investigate the effect of Brandt-Daroff habituation training combined with reposition chair(SRM-Ⅳ BPPV system)on the efficacy of reduction treatment,residual dizziness after successful treatment,anxiety and depression,and quality of life in patients with BPPV,and to provide clinical evidence-based basis for improving the prognosis and efficacy of reduction treatment in patients with BPPV.MethodsAccording to the inclusion and exclusion criteria,patients were admitted to the otolargology department of a third-grade general hospital from February 2021 to December 2021.After medical history screening,Dix Hallpike and Roll maneuver test,the patients were diagnosed as BPPV.In addition,90 patients who underwent reposition chair(SRM-Ⅳ BPPV system)treatment were included in this study,and divided into intervention group of 46 patients and control group of 44 patients according to random grouping method.The control group received conventional treatment nursing,and the intervention group received Brandt-Daroff training on the basis of the control group,with specific postural exercises to help improve the treatment effect and prognosis.The duration of intervention was one month for both groups.The Dizziness Handicap Inventory(DHI),Vestibular Disorders Activities of Daily Living Scale(VADL),and Hospital Anxiety and Depression Scale(HADS)were filled in before intervention,one week after intervention and one month after intervention respectively,the therapeutic effect and residual dizziness were evaluated after intervention.Comprehensive evaluation of the Brandt-Daroff habituation training combined with reposition chair(SRM-Ⅳ BPPV system)in the treatment effect,residual symptoms,vertigo disability degree,anxiety and depression,quality of life effect of intervention.SPSS25.0 was used for statistical analysis.Results1.Comparison of general data: there were no significant differences between the two groups in age,gender,ethnicity,education level,occupational status,income of family,payment method,exercises,co-chronic diseases and disease understanding degree(P>0.05).2.Comparison of treatment effects: the total effective rate of the intervention group was 100%,and that of the control group was 95.12%,with no statistical significance(P>0.05).3.Comparison of residual dizziness: One week after intervention,there was no statistically significant difference in the incidence and duration of residual dizziness between the intervention group and the control group(P>0.05);One month after intervention,there were statistically significant differences in the incidence and duration of residual dizziness between the intervention group and the control group(P<0.05).4.Comparison of the vertigo disability degree: DHI total score(DHI-T)and functional score(DHI-P),emotion score(DHI-E)and body score(DHI-F)were lower both in the intervention group and the control group than before intervention,with statistical significance(P<0.05).The intervention group was significantly lower than the control group after one week and one month of intervention(P<0.05).DHI scores had statistical significance in time effect,group effect and interaction effect(P<0.001).5.Comparison of daily quality of life: After one week and one month of Intervention,VADL total Score(VADL-T)and basic function(VADL-F),walking(VADL-A),auxiliary skills(VADL-I)scores,the intervention group and control group were lower than before the intervention,the difference was statistically significant(P<0.05).and the scores of intervention group was lower than the control group,the difference was statistically significant(P<0.05).VADL scores were affected by time effect,group effect,the interactions were statistically significant(P<0.001).6.Comparison of anxiety and depression Scale Scores: One week after intervention and one month after intervention,anxiety scores(HADS-A)and depression scores(HADS-D)in the intervention group and control group both were lower than before intervention,the difference was statistically significant(P<0.05).The intervention group was significantly lower than the control group on anxiety scores(HADS-A)and depression scores(HADS-D)(P<0.05).The time effect,group effect and interaction effect of anxiety and depression scores were statistically significant(P<0.001).Conclusion1.Brandt-Daroff habituation training combined with reposition chair(SRM-ⅣBPPV system)effectively relieved vertigo symptoms and improved the treatment outcome of patients with BPPV.2.Brandt-Daroff training combined with reposition chair(SRM-Ⅳ BPPV system)can reduce the incidence of residual dizziness,reduce the duration of residual dizziness,and accelerate the recovery of patients with BPPV.3.Brandt-Daroff training combined with reposition chair(SRM-Ⅳ BPPV system)can effectively relieve anxiety and depression,improve the quality of life and improve the prognosis of patients with BPPV.
