OBJECTIVE
The aim of the study was to evaluate the effect on health outcomes of an early or immediate return-to-work (RTW) after acute low back pain (LBP).
METHODS
A longitudinal cohort of workers (N = 557) consulting for uncomplicated LBP were assessed on demographic, pain, occupational, and psychosocial variables. Pain and function were assessed at 3-month postpain onset. We tested the longitudinal effects of an early RTW on 3-month outcomes.
RESULTS
Pain and function improved more rapidly for workers with an immediate (30.7%) or early (1 to 7 days) RTW (36.8%). Eleven demographic, health, or workplace variables were identified as potential confounds, but controlling for these factors only partially attenuated the benefits of an early RTW.
CONCLUSIONS
An early RTW improves acute LBP and functional recovery, and alternate confounding explanations only partially eclipse this therapeutic effect.
目的
本研究旨在评估急性腰痛（LBP）后早期或立即重返工作岗位（RTW）对健康结果的影响。
方法
对 557 名患有单纯性腰痛的工人进行了一项纵向队列研究，评估了人口统计学、疼痛、职业和心理社会变量。疼痛和功能在疼痛发作后 3 个月进行评估。我们测试了早期 RTW 对 3 个月结果的纵向影响。
结果
立即（30.7%）或早期（1 至 7 天）RTW 的工人疼痛和功能恢复得更快（36.8%）。确定了 11 个人口统计学、健康或工作场所变量作为潜在的混杂因素，但控制这些因素仅部分减弱了早期 RTW 的益处。
结论
早期 RTW 可改善急性 LBP 和功能恢复，而替代的混杂解释仅部分掩盖了这种治疗效果。
