To estimate the prevalence of insomnia in patients with chronic back pain, and to correlate insomnia with severity of back pain and disability.
63 women and 57 men aged 24 to 83 (mean, 55) years who presented with chronic back pain for >6 months were asked to complete a self-administered questionnaire to evaluate the Insomnia Severity Index (ISI), Oswestry Disability Index (ODI), and Numerical Rating Scale (NRS) for back pain.
Of the 120 patients, 25 had no insomnia, 39 had sub-threshold insomnia, and 56 had clinically significant insomnia. According to the ODI, disability was minimal in 12 patients, moderate in 38, severe in 43, bed-binding in 26, and crippling in one. Of the 120 patients, 91 rated their NRS for back pain as 5 to 10 and 29 rated it as 1 to 4. Correlation was stronger between ISI and ODI than between ISI and NRS for back pain (r=0.59 vs. r=0.38).
47% of patients with chronic back pain had insomnia. The ODI was more reliable than the NRS for back pain to detect insomnia. Back pain should be treated early to avoid serious health problems associated with insomnia.
评估慢性背痛患者失眠的患病率，并将失眠与背痛严重程度和残疾情况相关联。
对63名女性和57名男性（年龄在24至83岁之间，平均55岁）进行研究，这些患者患有慢性背痛超过6个月，要求他们完成一份自评问卷，以评估失眠严重程度指数（ISI）、奥斯维斯特残疾指数（ODI）和背痛数字评定量表（NRS）。
在120名患者中，25人无失眠，39人有亚阈值失眠，56人有临床显著失眠。根据ODI，12名患者残疾程度轻微，38名患者中度残疾，43名患者重度残疾，26名患者需卧床，1名患者致残。在120名患者中，91人将其背痛的NRS评定为5至10，29人评定为1至4。ISI与ODI之间的相关性比ISI与背痛NRS之间的相关性更强（r = 0.59对r = 0.38）。
47%的慢性背痛患者患有失眠。对于检测失眠，ODI比背痛的NRS更可靠。应尽早治疗背痛，以避免与失眠相关的严重健康问题。
