Previous studies using a primary task procedure have demonstrated that an experimental pain stimulus interrupts ongoing task performance in healthy volunteers and patients, and that this interruption is intensified by catastrophic thinking about pain and the perceived threat value of the pain stimulus. However, no studies have investigated the interruption of attention by relevant threatening stimuli in specific patient samples. In the present study, 40 patients with chronic whiplash syndrome and 40 healthy controls performed a primary task while simultaneously a potentially threatening neck fixation (i.e., extension and rotation) was imposed. Pain catastrophizing, fear of movement/(re)injury, hypervigilance, and depression were assessed. The patients showed a more pronounced deterioration of performance compared to controls when the neck rotation and extension fixations were introduced. Within the groups, neither catastrophic thinking nor fear predicted the magnitude of the performance deterioration.
以往使用主要任务程序的研究表明，实验性疼痛刺激会干扰健康志愿者和患者正在进行的任务表现，并且这种干扰会因对疼痛的灾难性思维以及疼痛刺激的感知威胁值而加剧。然而，尚无研究调查特定患者样本中相关威胁性刺激对注意力的干扰情况。在本研究中，40名慢性挥鞭样综合征患者和40名健康对照者在执行一项主要任务的同时，颈部被施加了一种潜在威胁性的固定（即伸展和旋转）。对疼痛灾难化、对运动/（再）受伤的恐惧、过度警觉和抑郁进行了评估。与对照组相比，当引入颈部旋转和伸展固定时，患者的表现恶化更为明显。在各小组中，无论是灾难性思维还是恐惧都无法预测表现恶化的程度。
