Physical signs, medical history and social factors were analyzed and evaluated in 52 patients (17 women and 35 men) with chronic low back pain, in order to determine if any factors were predictive for return to work after rehabilitation. Factors discriminating between the working and sick-disabled groups were: Sex (only men returned to full time work), Duration of sick-leave (the older half of the study population exhibited a negative correlation between time on sick-leave and frequency of return to work), Reported need for analgesics (the working group reported less need of analgesics), Pain in the cervical and dorsal areas of the spine as well as in the lumbar region (less frequent in the working group), The patients' attitude to his own ADL-capacity (those who returned to full-time work were more positive), After work fatigue (less frequent in the working group).
对52例慢性下腰痛患者（17名女性和35名男性）的体征、病史和社会因素进行了分析和评估，以确定是否有任何因素可预测康复后能否重返工作岗位。区分在职组和病残组的因素有：性别（只有男性恢复了全职工作）、病假时长（研究人群中年龄较大的一半显示病假时间与重返工作频率呈负相关）、报告的镇痛药需求（在职组报告的镇痛药需求较少）、脊柱颈段和背段以及腰段疼痛（在职组中频率较低）、患者对自身日常生活活动能力的态度（恢复全职工作的人态度更积极）、工作后疲劳（在职组中频率较低）。
