Retrospective cohort study.
Current evaluation of patients with adult spinal deformity (ASD) is mainly based on radiographic parameters derived from X-rays. However, due to their static nature, X-rays fall short of assessing the dynamic functionalities including balance, gait, and the risk of falling. This study aimed to determine the functionalities of ASD patients by measuring functional mobility tests (FMTs) and compared the relationships between patient-reported outcomes (PROs) with FMTs and radiographic parameters to determine whether FMTs are useful evaluation tools for the evaluation of patients with ASD.
This age- and sex-matched case-control study included 66 patients with ASD and 66 patients with LSS, all of whom were scheduled to undergo spinal surgery. All patients were evaluated with four FMTs including alternate step test (AST), six-meter walk test (SMT), sit-to-stand test (STS), and timed up and go test (TUGT). Correlations of the PROs with FMTs and static radiographic parameters were analyzed.
The baseline characteristics were not significantly different between the two groups. However, compared with patients with LSS, those with ASD showed significantly poorer performance on all four FMTs, spending significantly more time performing the SMT, STS, and TUGT (P = 0.046, 0.045, and 0.015, respectively). The results of the four FMTs were significantly correlated with the ODI (Oswestry Disability Index) scores only in the ASD group and not in the LSS group.
FMTs were appropriate tools for assessing the dynamic functionalities of patients with ASD. FMTs might play a bridging role between static radiographic parameters and subjective PROs when treating patients with ASD.
回顾性队列研究。
目前，成人脊柱畸形（ASD）患者的评估主要基于 X 射线得出的影像学参数。然而，由于其静态性质，X 射线无法评估包括平衡、步态和跌倒风险在内的动态功能。本研究旨在通过测量功能性移动测试（FMT）来确定 ASD 患者的功能，并比较患者报告的结果（PROs）与 FMT 和影像学参数之间的关系，以确定 FMT 是否是评估 ASD 患者的有用评估工具。
这项年龄和性别匹配的病例对照研究纳入了 66 例 ASD 患者和 66 例 LSS 患者，所有患者均计划接受脊柱手术。所有患者均接受了四项 FMT 评估，包括交替踏步测试（AST）、六米步行测试（SMT）、坐站测试（STS）和计时起立行走测试（TUGT）。分析了 PROs 与 FMT 和静态影像学参数的相关性。
两组患者的基线特征无显著差异。然而，与 LSS 患者相比，ASD 患者在所有四项 FMT 中的表现明显较差，完成 SMT、STS 和 TUGT 的时间明显更长（分别为 P=0.046、0.045 和 0.015）。四项 FMT 的结果仅在 ASD 组与 ODI（Oswestry 残疾指数）评分显著相关，而在 LSS 组不相关。
FMT 是评估 ASD 患者动态功能的合适工具。在治疗 ASD 患者时，FMT 可能在静态影像学参数和主观 PROs 之间起到桥梁作用。
