Treatment of visual perceptual disorders post stroke.

Visual perceptual disorders are a common clinical consequence of stroke. They include unilateral neglect, which has a major impact on rehabilitation outcome. The nature of the behavioral deficits associated with neglect has suggested that behavioral modification strategies may improve performance. This article presents a critical review and synthesis of published research evidence for the effectiveness of treatments for visual perceptual disorders after stroke. The strongest evidence for rehabilitation effectiveness was for the following: (a) specific treatment for perceptual disorders; and (b) specific training for neglect (including visual scanning). Findings also suggest that more research is needed into how the assessment of specific features of visual perceptual disorders might lead to improved methods for rehabilitation, including the use of assistive devices for mobility and activities of daily living.
