同名视野丧失的提醒提示扫描训练
针对同名视野丧失患者的提醒提示扫描训练
研究概览
详细说明
同名视野丧失是指双眼同侧视力丧失。 最常见的类型是偏盲（丧失一半的视野）和四角盲（丧失四分之一的视野）。 偏盲和象限盲可能会导致看清视野损失一侧的物体出现困难。 患有这些类型的场损失的人可以通过向场损失的一侧进行扫描（观察）来进行补偿。 然而，有时它们的扫描效果可能不够好，导致驾驶时对危险的反应延迟。 本研究的目的是评估一种新方法“提醒提示扫描训练”，以训练同名视野丧失的人在驾驶时进行扫描。
参与者将在驾驶模拟器中接受提醒提示扫描培训。通常在大约两周的时间内会有三节培训课程。 此外，学员将在培训前后在驾驶模拟器中完成评估。

Number of Head Scans to the Side of the Field Loss
大体时间：Pre-training, Post-training (1 week)
|
Number of head scans per intersection to the side of the field loss. A validated algorithm was used to detect head scans, defined as lateral rotations of the head away from the straight ahead position toward either the left or the right, which exceeded a predefined threshold based on the participant's distance to the intersection: ≥ 4° (100 to 50 m to intersection), ≥ 6° (50 to 20m), ≥ 10° (20 to 0m).

Magnitude of Head Scans to the Side of the Field Loss
大体时间：Pre-training, Post-training (1 week)
|
Mean magnitude (in degrees) of head scans to the side of the field loss. A validated algorithm was used to detect head scans, defined as lateral rotations of the head away from the straight ahead position toward either the left or the right, which exceeded a predefined threshold based on the participant's distance to the intersection: ≥ 4° (100 to 50 m to intersection), ≥ 6° (50 to 20m), ≥ 10° (20 to 0m). The magnitude is the lateral angular extent of the scan measured from the straight-ahead position to the furthest lateral position to the left or right.
