Effects of Nonpharmacological Interventions for Dizziness in Older XXXX : Systematic Review.

@entity1 @entity345 @entity1296
BACKGROUND: Nonpharmacological interventions have been shown to have some effectiveness in adults with @entity1296 ; however, the effectiveness of these interventions in older @entity1 is unknown. PURPOSE: The aim of this study was to determine the effects of conservative nonpharmacological interventions for @entity1296 in older @entity1 . DATA SOURCES: The Cochrane Central Register of Controlled Trials, PubMed, EMBASE, SCOPUS, CINAHL, AMED, Index to Chiropractic Literature, PsycINFO, and MANTIS were searched from inception to May 2014. STUDY SELECTION: Two investigators independently screened controlled trials with @entity1 who were more than 60 years old and experienced @entity1296 . Studies of @entity1 with @entity1296 from a specific diagnosis, such as M  ni  re disease and @entity345 , were excluded. Outcome measures from the selected studies included self-reported @entity1296 and postural balance. DATA EXTRACTION: Two investigators independently extracted data on @entity1 , interventions, comparison group, outcome measures, and results. The risk of bias of the included studies was assessed with Cochrane guidelines. DATA SYNTHESIS: Seven articles consisting of 7 controlled trials were included. All studies involved some form of exercise, including vestibular rehabilitation exercises, postural balance exercises, and tai chi exercise, as the main intervention. The studies had a high risk of bias because of the lack of adequate randomization and allocation concealment, the lack of reporting on cointerventions, the lack of reporting on reasons for dropouts, and the lack of reporting on @entity1 adherence. LIMITATIONS: Heterogeneity among the included studies in interventions and outcome measures prohibited a meta-analysis. Only 2 studies reported a significant difference between the intervention group and the comparison group for self-reported @entity1296 . CONCLUSIONS: There is insufficient evidence to determine the effectiveness of nonpharmacological treatments for @entity1296 in older @entity1 . Current evidence is hampered by a high risk of bias, and well-designed trials with adequate masking, randomization, and adherence are needed.
