Sagittal parameters are significantly correlated with health-related quality of life (HRQoL) in adult spinal deformity patients. Their association with HRQoL in patients with nonspecific chronic low back pain (NSCLBP) is unclear.
To analyze the correlation between sagittal parameters and disability in NSCLBP patients.
A cross-sectional study.
Subjects included 435 patients with NSCLBP divided into low disability and high disability groups.
Function was measured using the Oswestry Disability Index (ODI). Pain intensity was measured using the Numeric Rating Scale (NRS) and HRQoL was measured using 36-item Short Form Health Survey (SF-36).
Sagittal parameters, demographic data, ODI, SF-36 eight-dimensional scores and NRS scores of patients with NSCLBP were collected. Taking ODI=20 as the cut-off value, patients were divided into low disability group (ODI≤20) and high disability group (ODI>20), and ODI were converted to Ranked ODI (RODI) accordingly. Univariate analysis of the correlation among age, gender, body mass index (BMI), sagittal parameters, RODI, SF-36 eight-dimensional scores, NRS scores were then conducted. The variables related to RODI were analyzed by logistic regression to discover their independent influence on RODI. p<.05 was considered to indicate statistical significance.
A total of 435 patients with NSCLBP were included. Univariate correlation analysis showed that the correlation coefficients between age, sacral slope-pelvic tilt (SS-PT), spinosacral angle (SSA) and RODI were (r=0.126, p<.01), (r=-0.115, p<.05), (r=-0.116, p<.05), respectively. The logistic regression analysis indicated that the regression coefficients of age and SSA were 0.030 (p=.001), -0.044 (p=.002), respectively, and the odds ratio and 95% confidence interval (CI) were 1.031 (1.012, 1.050), 0.957 (0.930, 0.985).
Age and SSA are independent factors for disability of NSCLBP. SSA can comprehensively reflect the sagittal balance of the spine of patients with NSCLBP. Decreased SSA represents poor sagittal balance, which will increase the disability of NSCLBP.
矢状参数与成人脊柱畸形患者的健康相关生活质量（HRQoL）显著相关。但其与非特异性慢性下腰痛（NSCLBP）患者 HRQoL 的关系尚不清楚。
分析 NSCLBP 患者矢状参数与残疾的相关性。
横断面研究。
本研究纳入了 435 例 NSCLBP 患者，根据残疾程度分为低残疾组和高残疾组。
采用 Oswestry 残疾指数（ODI）评估功能；采用数字评分量表（NRS）评估疼痛强度；采用 36 项简明健康调查量表（SF-36）评估 HRQoL。
收集 NSCLBP 患者的矢状参数、人口统计学数据、ODI、SF-36 八维度评分和 NRS 评分。以 ODI=20 为截值，将患者分为低残疾组（ODI≤20）和高残疾组（ODI>20），并相应转换为秩 ODI（RODI）。对年龄、性别、体重指数（BMI）、矢状参数、RODI、SF-36 八维度评分和 NRS 评分进行单因素相关性分析。对与 RODI 相关的变量进行 logistic 回归分析，以发现其对 RODI 的独立影响。p<.05 表示具有统计学意义。
共纳入 435 例 NSCLBP 患者。单因素相关性分析显示，年龄、骶骨倾斜骨盆倾斜角（SS-PT）、脊柱骶骨角（SSA）与 RODI 的相关系数分别为（r=0.126，p<.01）、（r=-0.115，p<.05）、（r=-0.116，p<.05）。logistic 回归分析显示，年龄和 SSA 的回归系数分别为 0.030（p=.001）和-0.044（p=.002），优势比和 95%置信区间（CI）分别为 1.031（1.012，1.050）和 0.957（0.930，0.985）。
年龄和 SSA 是 NSCLBP 残疾的独立因素。SSA 可全面反映 NSCLBP 患者脊柱矢状平衡。SSA 降低代表矢状平衡不良，会增加 NSCLBP 的残疾程度。
