A Systematic Review and Meta-Analysis of Rehabilitative Interventions for Unilateral Spatial Neglect and Hemianopia Poststroke From 2006 Through 2016.

To evaluate the effectiveness of activity-based, nonactivity-based, and combined activity- and nonactivity-based rehabilitative interventions for individuals presenting with unilateral spatial neglect (USN) and hemianopia. We searched CINAHL, Cochrane Library, EMBASE, MEDLINE, and PubMed from 2006 to 2016. Randomized controlled trials (RCTs) with a score of 6 or more in the Physiotherapy Evidence Database Scale that examined the effects of activity-based and nonactivity-based rehabilitation interventions for people with USN or hemianopia. Two reviewers selected studies independently. Extracted data from the published RCTs. Mean differences (MD) or standardized mean differences (SMD), and 95% confidence intervals (CIs) were calculated. Heterogeneity was assessed using the I A total of 20 RCTs for USN and 5 for hemianopia, involving 594 and 206 stroke participants respectively, were identified. Encouraging results were found in relation to activity-based interventions for visual scanning training and compensatory training for hemianopia (MD=5.11; 95% confidence intervals [95% CI], 0.83-9.4; P=.019; I Activity-based interventions are effective and commonly used in the treatment of USN and hemianopia. Nonactivity-based and combined approaches, for both impairments, have not been refuted, because more studies are required for substantiated conclusions to be drawn.
