Abstract

BACKGROUND AND AIMS

Interrupting ongoing activities with the intention to resume them again later is a natural response to pain. However, such interruptions might have negative consequences for the subsequent resumption and performance of the interrupted activity. Activity interruptions by pain may be more impairing than interruptions by non-painful stimuli, and also be subjectively experienced as such. These effects might be more pronounced in people high in pain catastrophizing. These hypotheses were investigated in two experiments.

METHODS

In Experiment 1, healthy volunteers (n=24) performed an ongoing task requiring a sequence of joystick movements. Occasionally, they received either a painful electrocutaneous or a non-painful vibrotactile stimulus, followed by suspension of the ongoing task and temporary engagement in a different task (interruption task). After performing the interruption task for 30s, participants resumed the ongoing task. As the ongoing task of Experiment 1 was rather simple, Experiment 2 (n=30) included a modified, somewhat more complex version of the task, in order to examine the effects of activity interruptions by pain.

RESULTS

Participants made more errors and were slower to initiate movements (Experiment 1 & 2) and to complete movements (Experiment 2) when they resumed the ongoing task after an interruption, indicating that interruptions impaired subsequent performance. However, these impairments were not larger when the interruption was prompted by painful than by non-painful stimulation. Pain catastrophizing did not influence the results.

CONCLUSIONS

Results indicate that activity interruptions by pain have negative consequences for the performance of an activity upon its resumption, but not more so than interruptions by non-painful stimuli. Potential explanations and avenues for future research are discussed.

IMPLICATIONS

Interrupting ongoing activities is a common response to pain. In two experiments using a novel paradigm we showed that activity interruptions by pain impair subsequent activity resumption and performance. However, this effect seems to not be specific to pain.

摘要

背景与目的

为了之后再继续而中断正在进行的活动是对疼痛的一种自然反应。然而，这种中断可能会对随后被中断活动的继续进行和表现产生负面影响。疼痛导致的活动中断可能比非疼痛刺激导致的中断更具损害性，并且人们主观上也会有这样的感受。在疼痛灾难化程度高的人群中，这些影响可能会更加明显。在两项实验中对这些假设进行了研究。

方法

在实验1中，健康志愿者（n = 24）执行一项需要按顺序进行操纵杆移动的持续任务。他们偶尔会受到一次疼痛的皮肤电刺激或非疼痛的振动触觉刺激，随后正在进行的任务暂停，并临时参与另一项任务（中断任务）。在执行中断任务30秒后，参与者继续进行正在进行的任务。由于实验1中的正在进行的任务相当简单，实验2（n = 30）采用了该任务的一个经过修改的、稍微更复杂的版本，以检验疼痛导致的活动中断的影响。
