研究设计。目的：对慢性和复发性腰痛的病程及其与残疾和药物使用的关系进行观察性研究，以每日日记记录为基础。描述自我报告慢性和复发性腰痛的个体的日常疼痛报告，研究腰痛的强度和发作性如何与残疾和药物使用相关，并根据Von Korff的慢性腰痛分类对受试者进行分类。背景资料摘要。腰痛的自然历史已经被描述，并提出了一些分类方案，但关于疼痛特征及其与残疾自我报告的关系的报道很少。在6个月的时间里，从94名自我报告慢性或复发性腰痛的参与者中收集了每日自我报告的疼痛强度、社交和工作残疾以及药物使用情况。一种描述慢性腰痛发作性的指标被开发出来。疼痛强度对残疾有显著影响。在发作期间，参与者明显有更大的残疾和药物使用。与工作相关的残疾和药物使用在发作的后半段显著增加。疼痛强度会影响残疾，但腰痛的偶发性也会影响工作和个人生活的能力。疼痛的间歇性增加可以显著改变残疾。慢性腰痛不应被视为一种静态现象。
Study Design. An observational study on the course of chronic and recurrent low back pain and its relation to disability and medication use performed on the basis of daily diary recording.Objectives. To provide a description of daily pain reporting by individuals with self-reported chronic and recurrent low back pain, to study how the intensity and episodic nature of low back pain is related to disability and medication use, and to classify subjects according to Von Korff's categories of chronic low back pain.Summary of Background Data. The natural history of low back pain has been described, and some classification schemes have been proposed, but little has been reported on pain characteristics and their relation to self-report of disability.Methods. Daily self-reports of pain intensity, social and work disability, and medication use were collected from 94 participants with self-reported chronic or recurrent low back pain over a 6-month period. A metric for describing the episodic nature of chronic low back pain was developed.Results. A significant effect of pain intensity on disability was found. During an episode, participants had significantly greater disability and medication use. Work-related disability and medication use was significantly greater in the latter half of an episode.Conclusions. Pain intensity can affect disability, but the episodic nature of low back pain also affects the ability to function in both work and personal life. Intermittent increases in pain can markedly alter disability. Chronic low back pain should not be treated as a static phenomenon.
