Abstract:
Objective To explore the efficacy of Da Shuyu Gao(DSG,a formulation developed from the modification of Shuyu Wan and Ziwan Decoction)in treating persistent postural-perceptual dizziness(PPPD)based on the theory of phlegm-qi obstruction.Methods A prospective study was conducted on 120 cases of PPPD patients admitted to the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from January 2022 to July 2023.The patients were randomly divided into a combination group and a control group using a random number table,with 60 patients in each group.The control group received conventional western medicine treatment(Betahistine+Mecobalamin),while the combination group was treated with the decoction of DSG orally in addition to the conventional treatment.The treatment course for the two groups lasted for 2 months.Before and after treatment,the two groups were observed in the changes of traditional Chinese medicine(TCM)syndrome score,Somatic Symptom Self-Rating Scale(SSSRS),Hamilton Anxiety Scale(HAMA)score,Hamilton Depression Scale(HAMD)score,Pittsburgh Sleep Quality Index(PSQI)score,and the frequency and duration of dizziness episodes.After two months of treatment,the clinical efficacy of the two groups was compared.Results(1)After 2 months of treatment,the total effective rate of the combination group was 93.33%(56/60),and that of the control group was 78.33%(47/60).The intergroup comparison(tested by chi-square test)showed that the clinical efficacy of the combination group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the scores of TCM symptoms of dizziness,tinnitus,vexation,irritability,dry mouth,and bitterness in the mouth in both groups were improved compared to those before treatment(P＜0.05),and the combination group showed significant improvement compared with the control group(P＜0.01).(3)After treatment,the scores of the cognitive,imaginative,biological,irritability,and inhibitory dimension of SSSRS,as well as the total scores on the SSSRS were significantly improved in both groups compared to those before treatment(P＜0.05),and the combination group showed significant improvement compared with the control group(P＜0.01).(4)After treatment,HAMA,HAMD,and PSQI scores were significantly decreased in both groups compared to those before treatment(P＜0.05),and the decrease in the combination group was superior to that in the control group(P＜0.01).(5)After treatment,the frequency and duration of dizziness episodes were significantly decreased in both groups compared to those before treatment(P＜0.05),and the decrease in the combination group was superior to that in the control group(P＜0.01).Conclusion DSG,formulated based on the theory of phlegm-qi obstruction and clinical practice,demonstrates significant efficacy in treating PPPD.It is effective in decreasing TCM syndrome scores,alleviating somatic symptoms,improving emotional disorders such as anxiety and depression,enhancing sleep quality,and reducing the frequency and duration of dizziness episodes,thereby improving patients'quality of life.The application of DSG will provide a new approach for the clinical treatment of PPPD.
