摘要 |
Purpose: Bottom-up-based
sensory stimulation has been useful in promoting recovery from post-stroke
neglect. Light and color are salient stimuli for guiding our orienting
behaviors and influence the degree of spatial bias. This study evaluated the
effects of lateralized light flash and color on spatial bias in unilateral
neglect (UN). Method: We enrolled 15
individuals with UN as a consequence of a right hemispheric stroke of less
than 65 days. This was a 3 × 3 design study with three conditions of lens
color (colorless, red, and blue) and three conditions of flash light
locations (no flash, left, and right). Results: All participants
showed a decrease in ipsilesional spatial bias under left-side light flash and
a red lens. Right-side light flash and a blue lens induced more rightward
bias than other conditions. Conclusions: This evidence
confirms the use of sensory stimulation to complement post-stroke UN
remediation. Lateralized light flash to the contralesional space and
red-colored lenses have beneficial effects on amelioration of UN, whereas
ipsilesional light flash and the color blue may exacerbate ipsilesional
spatial bias in stroke survivors with UN. |
