Many conventional rehabilitation exercises, such as pencil-and-paper and computer tasks, may not train perceptual and motor skills as applied to a complex, multiskill activity such as driving. The present study examined the usefulness of the Dynavision apparatus for driving-related rehabilitation. The Dynavision was designed to train visual scanning, peripheral visual awareness, visual attention, and visual-motor reaction time across a broad, active visual field.
Ten persons with a cerebrovascular accident participated in the study. All had failed behind-the-wheel driving assessments. Subjects participated in a 6-week Dynavision training program using exercises designed to impose various motor, perceptual, and cognitive demands.
Dynavision training resulted in significantly improved behind-the-wheel driving assessments as compared to expected outcomes. Comparisons between pretests, posttests, and follow-up tests on a number of Dynavision, response, and reaction time variables showed significant improvements and maintenance effects. Dynavision performance, and, to a lesser extent, choice visual reaction and response times, were found to differentiate between persons assessed as safe and unsafe to drive, and between older and younger drivers. Subject self-reports suggested that a variety of training-related improvements had occurred in everyday functioning.
Dynavision training shows some rehabilitative promise for improving driving and basic psychomotor skills. Future research on the benefits and limitations of this apparatus should use finer laboratory skill measures and more comprehensive tests of driving and daily functioning to assess more thoroughly skill improvements in persons after stroke.
许多传统的康复训练，如纸笔和计算机任务，可能无法针对像驾驶这样复杂的多技能活动来训练感知和运动技能。本研究考察了Dynavision设备在与驾驶相关的康复训练中的效用。Dynavision旨在训练在广阔的活动视野范围内的视觉扫描、周边视觉感知、视觉注意力以及视觉运动反应时间。
十名脑血管意外患者参与了本研究。他们均未能通过驾驶评估。受试者参加了一个为期6周的Dynavision训练项目，该项目使用了旨在施加各种运动、感知和认知要求的练习。
与预期结果相比，Dynavision训练使驾驶评估得到显著改善。对一些Dynavision、反应和反应时间变量进行的预测试、后测试和随访测试之间的比较显示出显著的改善和维持效果。发现Dynavision表现，以及在较小程度上的选择视觉反应和反应时间，能够区分被评估为驾驶安全和不安全的人，以及老年和年轻驾驶者。受试者的自我报告表明，日常功能在与训练相关的多个方面都有所改善。
Dynavision训练在改善驾驶和基本心理运动技能方面显示出一定的康复前景。未来关于该设备的益处和局限性的研究应采用更精细的实验室技能测量方法，以及对驾驶和日常功能进行更全面的测试，以更彻底地评估中风患者技能的改善情况。
