Abstract

Laboratory studies and investigations of patients undergoing painful procedures have compared recalled pain to an average of multiple momentary reports taken throughout the painful experience. This work has shown that recalled ratings of pain are more closely associated with a combination of peak pain and pain proximal to the recall ratings than an average of all momentary reports. However, these studies have examined recalled pain over relatively short periods, usually under 1 hour. In this study of 32 patients with rheumatoid arthritis, momentary pain ratings taken over a 7-day period were compared with pain recalled on the eighth day. Analyses confirmed that a combination of peak and recent pain was a better predictor of recalled patient pain than was a simple average of all momentary pain reports. These results extend our understanding of how individuals remember pain and suggest alternative methods for assessing recalled pain.

摘要

针对正在接受疼痛治疗的患者的实验室研究和调查,已将回忆起的疼痛与在整个疼痛体验过程中多次即时报告的平均值进行了比较。这项研究表明,与所有即时报告的平均值相比,回忆起的疼痛评分与峰值疼痛以及回忆评分附近的疼痛的组合更为密切相关。然而,这些研究考察的是相对较短时间段内的回忆疼痛,通常在1小时以内。在这项针对32名类风湿性关节炎患者的研究中,将7天内的即时疼痛评分与第8天回忆起的疼痛进行了比较。分析证实,与所有即时疼痛报告的简单平均值相比,峰值疼痛和近期疼痛的组合能更好地预测患者回忆起的疼痛。这些结果拓展了我们对个体如何记忆疼痛的理解,并为评估回忆疼痛提供了替代方法。
