This study aimed to (1) compare postural sway patterns between individuals with chronic low back pain (CLBP) and asymptomatic controls, (2) evaluate correlations between pain severity and postural stability variables, and (3) assess the interaction effects of age, BMI, pain severity, and disability on postural stability under eyes-open and eyes-closed conditions.
Postural stability (sway area, sway velocity, CoP displacement) was assessed in 88 CLBP patients and 88 controls using a stabilometric platform. Pain severity (VAS) and disability (ODI) were recorded alongside demographic data. Statistical analyses included -tests, Pearson's correlations, and ANOVA to explore group differences, correlations, and interaction effects.
Chronic low back pain patients exhibited significantly greater postural sway across all conditions, with larger sway area (16.80 ± 6.10 cm vs. 11.50 ± 4.10 cm, = 0.004) and higher sway velocity (4.10 ± 1.40 cm/s vs. 2.90 ± 1.00 cm/s, = 0.009) under eyes-closed conditions. Pain severity correlated with sway velocity ( = 0.52, = 0.003) and CoP displacement ( = 0.57, = 0.002). Interaction effects indicated greater instability in older, obese individuals with severe pain and high disability.
Chronic low back pain is associated with impaired postural stability, influenced by pain severity, BMI, age, and disability. Targeted interventions addressing these factors are essential for improving balance and reducing fall risk.
本研究旨在（1）比较慢性下腰痛（CLBP）患者与无症状对照组之间的姿势摇摆模式；（2）评估疼痛严重程度与姿势稳定性变量之间的相关性；（3）评估年龄、体重指数、疼痛严重程度和残疾对睁眼和闭眼条件下姿势稳定性的交互作用。
使用稳定测量平台对88例CLBP患者和88例对照组进行姿势稳定性（摇摆面积、摇摆速度、重心位移）评估。同时记录疼痛严重程度（视觉模拟评分法）和残疾程度（功能障碍指数）以及人口统计学数据。统计分析包括t检验、Pearson相关性分析和方差分析，以探讨组间差异、相关性和交互作用。
慢性下腰痛患者在所有条件下均表现出明显更大的姿势摇摆，在闭眼条件下摇摆面积更大（16.80±6.10cm对11.50±4.10cm，P=0.004），摇摆速度更高（4.10±1.40cm/s对2.90±1.00cm/s，P=0.009）。疼痛严重程度与摇摆速度（r=0.52，P=0.003）和重心位移（r=0.57，P=0.002）相关。交互作用表明，年龄较大、肥胖、疼痛严重且残疾程度高的个体不稳定程度更高。
慢性下腰痛与姿势稳定性受损有关，受疼痛严重程度、体重指数、年龄和残疾程度影响。针对这些因素的针对性干预对于改善平衡和降低跌倒风险至关重要。
