To analyze the associations between lifting capacity, and central sensitization (CS) and non-organic signs (NOS) in patients with chronic back pain (CBP) attending vocational rehabilitation.
Cross-sectional observational multicenter study among patients with CBP undergoing a return to work assessment within care as usual. Main analyses: step 1: partial correlation between lifting capacity, and CS, NOS, and additional variables; step 2: multiple regression in stepwise forward method for dependent variable lifting capacity, and for independent variables CS and NOS, and additional variables significant ( < 0.05) at step 1. All analyses were controlled for sex.
Fifty-six patients of mean age 42.5 years and 59% women participated in the study. Correlations between lifting capacity and CS and NOS were = -0.53 and = -0.50, respectively. CS and NOS, as well as age and sex, contributed significantly to the final regression model, which explained 57.6% of variance.
After controlling for confounders, CS and NOS were negatively associated with lifting capacity in patients with CBP. Explained variance was substantially higher than previously reported studies.Implications for RehabilitationThe identification of central sensitization and non-organic signs (NOS) in patients with chronic back pain can alert clinicians about central nervous system being in a hypersensitive state and about pain behavior.Central sensitization and NOS are relevant determinants of lifting capacity.Better understanding of the factors affecting lifting capacity lead to better design and tailoring of interventions, resulting in optimized vocational rehabilitation programs and faster return to work.
分析慢性腰痛（CBP）患者的举重能力与中枢敏化（CS）和非器质性体征（NOS）之间的相关性，这些患者正在接受职业康复评估。
这是一项在常规护理中接受重返工作评估的慢性腰痛患者参与的横断面观察性多中心研究。主要分析：步骤 1：举重能力与 CS、NOS 和其他变量之间的偏相关；步骤 2：逐步向前法的多元回归，因变量为举重能力，自变量为 CS 和 NOS 以及在步骤 1 中具有统计学意义（ < 0.05）的其他变量。所有分析均控制了性别。
56 名患者的平均年龄为 42.5 岁，女性占 59%。举重能力与 CS 和 NOS 之间的相关性分别为 = -0.53 和 = -0.50。CS 和 NOS 以及年龄和性别对最终回归模型有显著贡献，该模型解释了 57.6%的方差。
在控制混杂因素后，CBP 患者的 CS 和 NOS 与举重能力呈负相关。解释的方差明显高于以前的研究报告。
在慢性腰痛患者中识别中枢敏化和非器质性体征（NOS）可以提醒临床医生中枢神经系统处于敏感状态和疼痛行为。CS 和 NOS 是举重能力的重要决定因素。更好地理解影响举重能力的因素可以导致更好地设计和调整干预措施，从而优化职业康复计划并更快地重返工作岗位。
