Despite strong suppositions concerning differences between patients suffering acute and chronic low back pain, relatively few data-based comparisons have been made. In this study, affective, cognitive, behavioral, and demographic contrasts were conducted. Chronic patients were divided into those who demonstrated signs and symptoms that were either congruent or incongruent with underlying anatomical and physiological principles. Low socioeconomic status, compensation claims, use of opiate analgesics, greater disability, catastrophizing cognitions, stronger emotionality, and passive coping were more characteristic of both acute and chronic incongruent patients than chronic congruent patients. A relatively stereotyped, spontaneous facial expression of pain was observed in all groups when responding to painful movements during a physical examination. The similarities between acute and chronic incongruent patients have implications for the assessment and treatment of low back pain.
尽管对于急性和慢性下背痛患者之间的差异有强烈的推测，但基于数据的比较相对较少。在本研究中，进行了情感、认知、行为和人口统计学对比。慢性患者被分为症状和体征与潜在解剖学和生理学原理相符或不符的两类。社会经济地位低、赔偿要求、使用阿片类镇痛药、残疾程度更高、灾难化认知、更强的情绪反应和消极应对在急性和慢性不相符患者中比慢性相符患者更具特征性。在体格检查中对疼痛动作做出反应时，所有组都观察到相对刻板、自发的疼痛面部表情。急性和慢性不相符患者之间的相似性对下背痛的评估和治疗具有启示意义。
