Homonymous visual field defects (HVFDs) are one of the most common consequences of stroke. Compensatory training encourages affected individuals to develop more efficient eye movements to improve function. However, training is typically supervised, which can be time consuming and costly.
To develop and evaluate the efficacy and feasibility of an unsupervised reading and exploration computer training for individuals with HVFDs.
Seventy individuals with chronic HVFDs were randomly assigned to 1 of 2 groups: intervention or control. The former received 35 hours of reading and exploration training, and the latter received 35 hours of control training. Visual and attentional abilities were assessed before and after training using perimetry, visual search, reading, activities of daily living, the Test of Everyday Attention, and a Sustained Attention to Response task.
Eighteen individuals failed to complete the training; analyses were conducted on the remaining 28 intervention and 24 control group participants. Individuals in the intervention group demonstrated significant improvements in the primary outcomes of exploration (12.87%, 95% confidence interval [CI] = 8.44% to 17.30%) and reading (18.45%, 95% CI = 9.93% to 26.97%), which were significantly greater than those observed following the control intervention (exploration = 4.80%, 95% CI = 0.09% to 9.51%; reading = 1.95%, 95% CI = -4.78% to 8.68%). Participants in the intervention group also reported secondary subjective improvements, although these were not matched by objective gains in tasks simulating activities of daily living.
Home-based compensatory training is an inexpensive accessible rehabilitation option for individuals with HVFDs, which can result in objective benefits in searching and reading, as well as improving quality of life.
同视性视野缺损（HVFDs）是中风最常见的后果之一。代偿性训练鼓励受影响的个体发展更有效的眼球运动，以改善功能。然而，训练通常是由监督的，这可能是耗时和昂贵的。
开发和评估一种用于 HVFD 患者的非监督阅读和探索计算机训练的疗效和可行性。
70 名慢性 HVFD 患者被随机分配到 2 组中的 1 组：干预组或对照组。前者接受 35 小时的阅读和探索训练，后者接受 35 小时的对照训练。使用视野计、视觉搜索、阅读、日常生活活动、日常注意测试和持续注意反应任务，在训练前后评估视觉和注意力能力。
18 名个体未能完成训练；对其余 28 名干预组和 24 名对照组参与者进行了分析。干预组个体在探索（12.87%，95%置信区间[CI] = 8.44%至 17.30%）和阅读（18.45%，95%CI = 9.93%至 26.97%）的主要结果中表现出显著改善，显著大于对照组（探索=4.80%，95%CI=0.09%至 9.51%；阅读=1.95%，95%CI=-4.78%至 8.68%）。干预组参与者还报告了次要的主观改善，尽管这些改善在模拟日常生活活动的任务中没有得到客观的收益。
基于家庭的代偿性训练是 HVFD 患者的一种廉价、可及的康复选择，可在搜索和阅读方面带来客观的收益，并提高生活质量。
