This study investigated attentional biases for pictorial headache-related stimuli in individuals with chronic headache and healthy controls.
Attentional bias was assessed using a visual probe task that presented headache-related images and neutral images at 2 exposure duration conditions, 500 and 1250 ms.
The results indicated that individuals with chronic daily headache showed a significantly greater overall attentional bias across presentation times toward headache-related stimuli compared with the controls, which indicates a bias in both initial orienting and maintained attention to pain cues in this group.
It is concluded that both hypervigilance and sustained processing are critical factors for the maintenance of chronic pain.
本研究调查了慢性头痛患者和健康对照组对图片性头痛相关刺激的注意偏向。
使用视觉探测任务评估注意偏向，该任务在 500 和 1250 ms 两种暴露持续时间条件下呈现头痛相关图像和中性图像。
结果表明，慢性每日头痛患者在整个呈现时间内对头痛相关刺激的总体注意偏向明显大于对照组，这表明该组对疼痛线索的初始定向和持续注意力存在偏向。
结论是，高度警觉和持续处理都是慢性疼痛维持的关键因素。
