Patients with chronic non-specific low back pain (CNSLBP) have pain, disability, and decreased functional capacity, however, the association is still unknown.
This study aimed to examine the association between pain, disability, and functional capacity in patients with CNSLBP.
Thirty participants with CNSLBP were interviewed for demographic data and assessed for pain intensity by visual analog scale (VAS), disability level by Oswestry Disability Index (ODI), and functional capacity comprising functional reach (FR), five times sit-to-stand (5STS), and two-minute step (2MS). The association and linear regression were analyzed using the Spearman correlation coefficient, point-biserial correlation, and multiple linear regression, respectively.
A significant association was found between VAS and ODI, VAS and 5STS, 5STS, and 2MS. For demographic data, some variables were significantly correlated to VAS and functional capacity. VAS was also correlated with sex and age, FR was correlated with height, 5STS was correlated with age, and 2MS was correlated with age, body mass index, and physical activity level.
The association among pain intensity, disability level, functional capacity, and demographic data suggests that apart from pain and disability level, functional capacity is associated with pain, which can be recommended for objective assessment regarding some demographic variables that can contribute to clinical outcome measures.
慢性非特异性下腰痛（CNSLBP）患者存在疼痛、残疾和功能能力下降，但两者之间的关联仍不清楚。
本研究旨在探讨 CNSLBP 患者疼痛、残疾和功能能力之间的关系。
对 30 名 CNSLBP 患者进行人口统计学数据访谈，并通过视觉模拟量表（VAS）评估疼痛强度、Oswestry 残疾指数（ODI）评估残疾程度、功能性伸展（FR）、五次坐站（5STS）和两分钟步测（2MS）评估功能能力。使用 Spearman 相关系数、点二项相关和多元线性回归分别分析相关性和线性回归。
VAS 与 ODI、VAS 与 5STS、5STS 与 2MS 之间存在显著相关性。对于人口统计学数据，一些变量与 VAS 和功能能力显著相关。VAS 与性别和年龄相关，FR 与身高相关，5STS 与年龄相关，2MS 与年龄、体重指数和身体活动水平相关。
疼痛强度、残疾程度、功能能力和人口统计学数据之间的关联表明，除了疼痛和残疾程度外，功能能力与疼痛相关，这可以为一些可能影响临床结局测量的人口统计学变量的客观评估提供依据。
