本研究调查了43名在体检期间暴露于疼痛的患者的疼痛强度预测、疼痛和焦虑报告、疼痛相关焦虑症状的频率和运动范围。所有患者均主诉腰痛。用于本研究的疼痛刺激包括通过反复抬起患者的伸展腿至疼痛耐受点而产生的背部和/或腿部疼痛。一般来说，研究结果表明：（a）疼痛预测是先前预测与疼痛体验之间差异的函数，（B）报告疼痛相关焦虑程度较高的患者显示出过度预测新疼痛事件的趋势，但很容易纠正其预测，（c）报告疼痛相关焦虑程度较低的患者显示出持续低估疼痛的趋势，以及（d）疼痛预测较高，与疼痛报告无关，与涉及疼痛运动的手术期间活动范围较小有关。讨论的重点是这些结果和以前的研究和不准确的预测持续疼痛和残疾的影响之间的差异。
This study investigated predictions of pain intensity, reports of pain and anxiety, frequency of pain-related anxiety symptoms, and range of motion, in 43 patients exposed to pain during a physical examination. All patients had primary complaints of low back pain. The pain stimuli used for this study included back and/or leg pain produced by repeatedly raising the extended leg of the patient to the point of pain tolerance. Generally, findings demonstrated that (a) predictions of pain were a function of discrepancies between previous predictions and experiences of pain, (b) patients reporting greater pain-related anxiety showed a tendency to overpredict new pain events, but corrected their predictions readily, (c) patients reporting less pain-related anxiety displayed a persistent tendency to underpredict pain, and (d) higher predictions of pain, independent of pain reports, related to less range of motion during a procedure that involved painful movement. Discussion focuses on differences between these results and those of previous studies and the implications of inaccurate prediction for continued pain and disability.
