Objective: To conduct a systematic review of clinical trials that examined the effectiveness of interventions on balance self-efficacy among individuals with stroke. Design: Systematic review. Summary of review: Searches of the following databases were completed in December 2014: MEDLINE (1948-present), CINAHL (1982-present), EMBASE (1980-present) and PsycINFO (1987-present) for controlled clinical trials that measured balance self-efficacy in adults with stroke. Reference lists of selected articles were hand-searched to identify further relevant studies. Review methods: Two independent reviewers performed data extraction and assessed the methodological quality of the studies using the Physical Therapy Evidence Database Scale. Standardized mean differences (SMD) were calculated. Results: A total of 19 trials involving 729 participants used balance self-efficacy as a secondary outcome. Study quality ranged from poor (n=3) to good (n=8). In the meta-analysis of 15 trials that used intensive physical activity interventions, a moderate beneficial effect on balance self-efficacy was observed immediately following the programs (SMD 0.44, 95% CI 0.11-0.77, P=0.009). In the studies that included follow-up assessments, there was no difference between groups across retention periods (eight studies, SMD 0.32, 95% CI -0.17-0.80, P=0.20). In the four studies that used motor imagery interventions, there was no between-group difference in change in balance self-efficacy (fixed effects SMD 0.68, 95% CI -0.33-1.69, P=0.18). Conclusions: Physical activity interventions appear to be effective in improving balance self-efficacy after stroke.
