Crotty M, George S. Retraining visual processing skills to improve driving ability after stroke.
To evaluate the effectiveness of retraining using the Dynavision on driving performance of people with stroke.
Randomized controlled trial.
Outpatient rehabilitation clinic in Australia.
People with stroke (N=26) referred for driving assessment.
Eligible participants were randomized to either receive retraining with the Dynavision apparatus for 18 sessions or to receive no intervention and go onto a waitlist.
The primary outcome was an assessment of on-road ability. Secondary outcomes included measures of response speed, visual scanning, and self-efficacy. All assessments were conducted by assessors blinded to group assignment.
No significant difference (P=.223) was found between the intervention and control groups in results of on-road assessment in terms of pass or fail; the primary outcome measure; or the results on the secondary outcome measures of response speed, visual scanning, and self-efficacy.
In this small trial, training underlying skills (such as executing a continuous wide scan, combining motor and visual processing into a motor response) using the Dynavision apparatus did not improve the outcomes of an on-road assessment for people after strokes. Larger trials are needed to evaluate devices that claim to retrain underlying skills related to driving.
Crotty M，George S. 通过重新训练视觉处理技能来提高中风后的驾驶能力。
评估使用 Dynavision 对中风患者驾驶能力进行再训练的效果。
随机对照试验。
澳大利亚门诊康复诊所。
接受驾驶评估的中风患者（N=26）。
符合条件的参与者被随机分配接受 Dynavision 设备的 18 次训练，或不接受干预并进入候补名单。
主要结果是道路行驶能力评估。次要结果包括反应速度、视觉扫描和自我效能感的测量。所有评估均由对分组分配不知情的评估员进行。
在道路评估方面，干预组和对照组之间在通过或失败（主要结果衡量指标），以及反应速度、视觉扫描和自我效能感的次要结果测量方面没有显著差异（P=.223）。
在这项小型试验中，使用 Dynavision 设备对潜在技能（如执行连续宽扫描、将运动和视觉处理结合成运动反应）进行训练并没有改善中风后患者的道路评估结果。需要更大的试验来评估声称可以重新训练与驾驶相关的潜在技能的设备。
