Inclusion of self-reported and capacity-based measures may help to further elucidate the interactive link between how people think and move.
To characterize the relationship between self-reported factors of physical function and pain with objective physical capacity measures.
Cross-sectional study of 328 adults with chronic low back pain (CLBP).
Spearman correlations assessed the relationship between pairs of measures. Multiple linear regression models assessed the association between self-reported measures of physical function and the grouping of physical capacity measures. Self-reported measures included Roland Morris Disability Questionnaire (RMDQ), PROMIS Physical Function, Pain Behavior, and Pain Interference; Fear-Avoidance Beliefs Questionnaire (FABQ), Pain Catastrophizing Scale (PCS), and Chronic Pain Acceptance Questionnaire (CPAQ). Capacity measures included walking speed and endurance, lower extremity functional strength, lumbopelvic range of motion, and trunk endurance.
PROMIS Physical Function was directly and weakly correlated with walking speed (ρ = 0.26, 2-min walk) and inversely and weakly correlated with lower extremity strength (ρ = -0.29, 5x sit-to-stand). RMDQ was not correlated with any of the capacity-based measures. PROMIS Physical Function was inversely and moderately correlated with Pain Interference (ρ = -0.48) and Pain Behavior (ρ = -0.43), PCS (ρ = -0.36), and FABQ (ρ = -0.31). The RMDQ was strongly correlated with PROMIS Physical Function (ρ = -0.56), Pain Behavior (ρ = 0.51) and Pain Interference (ρ = 0.49); and moderately correlated with PCS (ρ = 0.37) and FABQ (ρ = 0.33). PROMIS Physical Function and RMDQ were not correlated with CPAQ. Lower scores on PROMIS Physical Function were weakly associated with lower measures of lower extremity strength (-0.30, 95% CI: -0.51 to -0.09, p = 0.005). Higher scores on RMDQ were also weakly associated with lower measures of lower extremity strength (0.26, 95% CI: 0.11 to 0.41, p = 0.001).
A strong association emerged between self-reported limitations in physical function, pain behavior, and pain interference. A weak association emerged between self-reported physical function and lower extremity strength.
纳入自我报告和基于能力的测量方法，可能有助于进一步阐明人们的思维和运动之间的交互关系。
描述自我报告的身体功能和疼痛相关因素与客观身体能力测量之间的关系。
328 例慢性下腰痛（CLBP）成人的横断面研究。
采用 Spearman 相关评估测量指标之间的关系。多元线性回归模型评估自我报告的身体功能指标与身体能力测量指标分组之间的相关性。自我报告的指标包括 Roland Morris 残疾问卷（RMDQ）、PROMIS 身体功能、疼痛行为和疼痛干扰；恐惧回避信念问卷（FABQ）、疼痛灾难化量表（PCS）和慢性疼痛接受问卷（CPAQ）。能力测量包括步行速度和耐力、下肢功能力量、腰骨盆运动范围和躯干耐力。
PROMIS 身体功能与步行速度（ρ=0.26，2 分钟步行）呈直接和弱相关，与下肢力量呈负相关（ρ=-0.29，5 次坐立）。RMDQ 与任何基于能力的测量指标均无相关性。PROMIS 身体功能与疼痛干扰（ρ=-0.48）和疼痛行为（ρ=-0.43）、PCS（ρ=-0.36）和 FABQ（ρ=-0.31）呈中度相关。RMDQ 与 PROMIS 身体功能（ρ=-0.56）、疼痛行为（ρ=0.51）和疼痛干扰（ρ=0.49）呈强相关，与 PCS（ρ=0.37）和 FABQ（ρ=0.33）呈中度相关。PROMIS 身体功能和 RMDQ 与 CPAQ 无相关性。PROMIS 身体功能评分较低与下肢力量测量值较低呈弱相关（-0.30，95%置信区间：-0.51 至 -0.09，p=0.005）。RMDQ 评分较高也与下肢力量测量值较低呈弱相关（0.26，95%置信区间：0.11 至 0.41，p=0.001）。
自我报告的身体功能、疼痛行为和疼痛干扰受限之间存在很强的相关性。自我报告的身体功能与下肢力量呈弱相关。
