Abstract: Article reviews 48 studies examining the effects of prism adaptation training on post-stroke spatial neglect. Spatial neglect, a failure to report, respond to, or orientate to contralesional stimuli, accompanied by functional disability, affects about half of all survivors of acute stroke. Stroke survivors with spatial neglect can demonstrate different symptoms: some have primarily ‘where’ spatial perceptual unawareness, whereas others have primarily ‘aiming’ spatial motor-exploratory dysfunction. Due to its effects on spatial motor 'aiming', prism adaptation training may act to reduce neglect-related disability. Prism adaptation therapy requires the stroke survivor to wear wedge prism lenses that laterally displace viewed objects rightward during intensive motor training. over a period of days to weeks. The reviewed research failed, first, to suggest methods to identify the 50 to 75 percent of patients who respond to treatment; second, to measure short-term and long-term outcomes in both mechanism-specific and functionally valid ways; third, to confirm treatment utility during the critical first 8 weeks poststroke; and last, to base treatment protocols on systematic dose-response data. Thus, considerable investment in prism adaptation research has not yet touched the fundamentals needed for clinical implementation. The authors recommend improved standards and better spatial motor models for further research, so as to clarify when, how and for whom prism adaptation should be applied.
