Abstract

Objective: To investigate if colored overlays influences reading performance in adults with an acquired brain injury (ABI).

Methods: An experimental cross-sectional study where patients with ABI and reading-related visual discomfort (n = 25) were recruited from an outpatient rehabilitation clinic. Reading speed with and without colored overlays was investigated using the Wilkins Rate of Reading Test (WRRT) and coherent text. Eye movements were recorded with the Readalyzer. The Visual Discomfort Scale (VDS) was used for symptom assessment.

Results: Reading of WRRT was faster with an overlay (3.9%, p = 0.04). Participants with lower baseline reading speed (without overlay) showed greater improvements when reading the WRRT (median increase 10.9, 4.6-67.0%) and coherent text (median increase17.5, 5.5-93.2%). Improvements were reflected in significantly fewer progressive and regressive saccades, and shorter fixation durations. Improvements in reading speed correlated positively with VDS score (p = 0.05).

Conclusions: The findings support the theory that colored overlays can facilitate reading in some patients. Possible mechanisms are discussed in relation to reading ability, visual, and cognitive functions. Further research will be needed to increase the understanding of sensory visual stress and the effect of colored overlays in the ABI population.

彩色复盖对获得性脑损伤患者阅读的影响。

目的：探讨彩色覆盖是否会影响获得性脑损伤（ABI）成人的阅读表现。方法：一项实验性横断面研究，从门诊康复诊所招募ABI和阅读相关视觉不适患者（n = 25）。使用威尔金斯阅读速度测试（WRRT）和连贯文本研究了有和没有彩色覆盖的阅读速度。用Readalyzer记录眼球运动。采用视觉不适量表（VDS）进行症状评估。结果：覆盖后WRRT读数更快（3.9%,p = 0.04）。基线阅读速度较低（无重叠）的参与者在阅读WRRT（中位数增长10.9%,4.6-67.0%）和连贯文本（中位数增长17.5%,5.5-93.2%）时表现出更大的改善。改善表现为进行性和退行性扫视明显减少，注视时间缩短。阅读速度的提高与VDS评分呈正相关（p = 0.05）。结论：研究结果支持彩色覆盖有助于某些患者阅读的理论。本文讨论了与阅读能力、视觉和认知功能相关的可能机制。需要进一步的研究来增加对感官视觉压力和ABI人群中彩色覆盖的影响的理解。
