Retrospective, observational study.
This study aimed to examine the association between spinopelvic parameters and balance function in low back pain (LBP).
Among patients in the rehabilitation medicine department, the data of 182 patients (mean age, 47.8 years; M/F = 64/118) was obtained retrospectively. Spinopelvic parameters were measured through a whole-body low-dose biplanar radiography using the EOS imaging system, and balance function was evaluated by the center of pressure (COP) movement using the Zebris treadmill system. Pearson correlations were used to determine the relationship between radiographic and balance function. Stepwise multiple linear regression analyses were conducted with the balance function as a dependent variable and age and spinopelvic parameters as independent variables.
Increased age, knee flexion (KF), pelvic tilt (PT), C7-central sacral line (C7-CSL) and C7 sagittal vertical axis (SVA), and decreased spino-sacral angle (SSA) were associated with both poor static and dynamic balance. Moreover, increased Cobb's angle and decreased thoracic kyphosis (TK) and lumbar lordosis (LL) was associated with poor static balance. Increased pelvic incidence (PI) was related to poor dynamic balance. Increased age, Cobb's angle, SVA, and decreased TK were risk factors for poor static balance. For dynamic balance, increased age, C7-CSL, and PT were risk factors for poor sagittal balance, whereas increased CAM-plumb line and PT were risk factors for poor coronal balance.
Balance function was associated with spinopelvic parameters in patients with LBP. Increased SVA, followed by increased PT, was the strongest independent factor associated with poor static and dynamic balance.
回顾性观察研究。
本研究旨在探讨下腰痛（LBP）患者的脊柱骨盆参数与平衡功能之间的关联。
回顾性收集康复医学科182例患者（平均年龄47.8岁；男/女 = 64/118）的数据。使用EOS成像系统通过全身低剂量双平面X线摄影测量脊柱骨盆参数，使用Zebris跑步机系统通过压力中心（COP）移动评估平衡功能。采用Pearson相关性分析确定影像学参数与平衡功能之间的关系。以平衡功能为因变量，年龄和脊柱骨盆参数为自变量进行逐步多元线性回归分析。
年龄增加、膝关节屈曲（KF）、骨盆倾斜（PT）、C7-骶骨中线（C7-CSL）和C7矢状垂直轴（SVA）增加，以及脊柱-骶骨角（SSA）减小与静态和动态平衡不良均相关。此外，Cobb角增加、胸椎后凸（TK）和腰椎前凸（LL）减小与静态平衡不良相关。骨盆入射角（PI）增加与动态平衡不良相关。年龄增加、Cobb角、SVA增加以及TK减小是静态平衡不良的危险因素。对于动态平衡，年龄增加、C7-CSL和PT增加是矢状面平衡不良的危险因素，而CAM铅垂线和PT增加是冠状面平衡不良的危险因素。
LBP患者的平衡功能与脊柱骨盆参数相关。SVA增加，其次是PT增加，是与静态和动态平衡不良相关的最强独立因素。
