Effect Of Rehabilitation Training And Brandt-Daroff On Residual Symptoms After Reduction Of Benign Paroxysmal Positional Vertigo

Objective: to evaluate the residual dizziness(RD)symptoms of patients with benign paroxysmal positional vertigo(BPPV)after successful reduction by different intervention methods for 7 days,14 days and 28 days,according to the scores of dizziness handicap inventory(DHI)and vestibular symptom index(VSI),and to explore the efficacy of different intervention methods in order to further guide the clinical treatment of RD symptoms.Methods: a total of 124 patients who were diagnosed as BPPV in our hospital from January 2020 to January 2022 and who met the inclusion and exclusion criteria by the guidelines for diagnosis and treatment of BPPV(2017)were enrolled in the study,who finally developed RD symptoms after successful reduction by standardized and unified manipulation.According to the principle of random grouping,the subjects were divided into three groups: control group(n = 42),rehabilitation group(n = 40)and exercise group(n = 42).After 7 days,14 days and28 days of treatment,the DHI and VSI scores of the patients in the three groups were recorded,and the data were collected and statistically analyzed by SPSS21.0software to draw a conclusion.Results: 1.The general data(age,sex,disease duration,damaged semicircular canal)and the scores of DHI and VSI of the three groups of patients at the time of enrollment were compared in the control,rehabilitation,and exercise groups,and the results suggested that the differences were not statistically significant(P> 0.05),indicating that the three groups of patients could be further compared.2.The scores of DHI at various time points were compared between the three groups,and the results suggested that the three groups patients at the time points of day 7,day 14,and day 28 DHI scores were compared,and the differences were statistically significant(P< 0.05).The results showed that the differences between the DHI scores of the rehabilitation group and the exercise group and the control group on days 7,14 and 28 were statistically significant(P< 0.05),and the DHI scores of the rehabilitation group and the exercise group were lower than those of the control group.The differences between the DHI scores of the rehabilitation group and the exercise group at day 7 and 14 were not statistically significant(P> 0.05),while the differences between the DHI scores of the rehabilitation group and the exercise group at day 28 were statistically significant(P< 0.05),and the scores of the rehabilitation group were lower than those of the exercise group.3.The results of comparing the VSI scores of the three groups at each time point suggest that the patients in the three groups were not affected at day 7,14 and 28.The differences were statistically significant(P< 0.05)when comparing the VSI scores of the three groups at the time points of day 7,day 14,and day 28.The results showed that the differences between the VSI scores of the rehabilitation group and the exercise group and the control group on days 7,14 and 28 were statistically significant(P< 0.05),and the VSI scores of the rehabilitation group and the exercise group were both lower than those of the control group.There was no statistically significant difference(P> 0.05)between the VSI scores of the rehabilitation group and the exercise group at day 7.The differences were statistically significant(P<0.05)when comparing the VSI scores of the rehabilitation group with those of the exercise group on days 14 and 28,and the scores of the rehabilitation group were lower than those of the exercise group.4.The comparison of DHI and VSI scores within the three groups suggested that the DHI and VSI scores decreased sequentially with time in the three groups,and the differences were statistically significant(P< 0.05).5.The comparison of DHI and VSI scores within the three groups,the former at the7 th day of treatment compared with the entry,the 14 th day of treatment compared with the 7th day of treatment,and the 28 th day of treatment compared with the 14 th day of treatment,were statistically significant(P< 0.05).The differences were all statistically significant(P< 0.05),with lower DHI and VSI scores in the former compared to the latter.Conclusions:1.All three interventions-pharmacotherapy alone,Rehabilitation Training combined with pharmacotherapy,Brandt-Daroff Exercise combined with pharmacotherapy-were effective in the treatment of RD symptoms.2.The effectiveness of the Rehabilitation Training method combined with pharmacotherapy and the Brandt-Daroff Exercise method combined with pharmacotherapy on the treatment of RD symptoms was significant compared with that of pharmacotherapy alone.3.There was no significant difference in the therapeutic effect of the Rehabilitation Training method combined with pharmacotherapy and the Brandt-Daroff Exercise method combined with pharmacotherapy on RD symptoms in a short period of time,but with the extension of the treatment time,the effect of the Rehabilitation Training method combined with pharmacotherapy was better than that of the Brandt-Daroff Exercise method combined with pharmacotherapy.
