Abstract

Backgrounds

Evaluation of gait posture using a three-dimensional motion analysis system (3DMAS) revealed that elderly patients with adult spinal deformity (ASD) experience pelvic anteversion while walking. The purpose of this study was to investigate the influence of changes in pelvic anteversion during gait on walking ability and physical function in patients with ASD.

Methods

Fifty-four patients with ASD aged 50 years or older who were admitted to our hospital between March 2016 and December 2021 were included in the study. The 6-min walking distance (6MWD) was used to evaluate walking ability, and trunk and hip extensor strength were measured to evaluate physical function in the subjects. The 3DMAS was used to measure the subject's changes in pelvic anteversion during gait. After measuring the changes in pelvic anteversion, the median value of the study subjects was calculated, according to which the subjects were divided into two groups (small anteversion [S] group, large anteversion [L] group). Walking ability and physical function were compared between the two groups.

Results

The number of subjects in each group was 27. Comparisons of walking ability and physical function between the groups revealed significant differences in 6MWD (S group, 333.6 ± 111.2 m; L group, 238.0 ± 106.3 m) and hip extensor strength (S group, 15.8 ± 3.8 kgf; L group, 13.4 ± 4.4 kgf). No significant differences regarding trunk extensor strength were observed between the groups (S group, 15.2 ± 4.0 kgf; L group, 12.9 ± 4.8 kgf).

Conclusion

The results of the present study revealed that ASD patients with greater pelvic anteversion associated with walking have lower walking ability and physical function. These results suggest the importance of evaluating the posture of ASD patients not only by using radiographic findings but also by assessing movement, such as gait posture.

成年脊柱畸形患者步态中骨盆前倾的变化对行走能力和身体功能的影响：一项横断面研究。

背景：使用三维运动分析系统（3DMAS）对步态进行评估后发现，患有成人脊柱畸形（ASD）的老年患者在行走时会出现骨盆内翻。本研究的目的是调查步态时骨盆内翻的变化对 ASD 患者行走能力和身体功能的影响：研究纳入了我院在 2016 年 3 月至 2021 年 12 月期间收治的 54 名年龄在 50 岁或以上的 ASD 患者。采用 6 分钟步行距离（6MWD）评估受试者的步行能力，测量躯干和髋关节伸展力量评估受试者的身体功能。3DMAS 用于测量受试者在步态过程中骨盆前屈的变化。测量骨盆内翻的变化后，计算出研究对象的中位值，并据此将研究对象分为两组（小内翻[S]组和大内翻[L]组）。比较两组的行走能力和身体功能：各组受试者人数均为 27 人。两组间行走能力和身体功能的比较显示，6MWD（S 组，333.6 ± 111.2 米；L 组，238.0 ± 106.3 米）和髋关节伸展力量（S 组，15.8 ± 3.8 kgf；L 组，13.4 ± 4.4 kgf）存在显著差异。各组之间的躯干伸展力量无明显差异（S 组，15.2 ± 4.0 kgf；L 组，12.9 ± 4.8 kgf）：本研究结果表明，与行走相关的骨盆内翻较大的 ASD 患者的行走能力和身体功能较低。这些结果表明，评估 ASD 患者的姿势不仅要通过影像学检查结果，还要通过步态等运动评估。
