This study aimed to compare the results of gait analysis of adolescent idiopathic scoliosis (AIS) patients and healthy subjects through a meta-analysis of the existing research. The Medline (via PubMed), Cochrane, Scopus, and Embase databases were searched for studies that evaluated the findings of AIS, including spatiotemporal parameters (walking speed, step length, cadence, and stance phase duration), segmental kinematics (frontal, sagittal, and transverse pelvic motion), and electromyographic variables (electrical activity of the quadratus lumborum, erector spinae, and gluteus medius), and were published between January 2000 and May 2020. Two authors extracted the data independently, and any discrepancies regarding the eligibility of retrieved studies were resolved by a consensus. Six comparative studies were identified and subsequently analyzed. It was found that the stance phase and frontal pelvic motion were significantly reduced in AIS patients compared with healthy controls. No significant difference was observed for speed, step length, cadence, sagittal pelvic motion, and transverse pelvic motion. The electrical activity durations of the quadratus lumborum, erector spinae, and gluteus medius were significantly increased in the AIS group compared with healthy subjects. Despite the heterogeneity, a limited number of meta-analyses showed reduced stance phase and frontal pelvic motion with prolonged activation timing of the quadratus lumborum, erector spinae, and gluteus medius muscles. Hence, further large-scale, multicenter studies are required to validate our results.
本研究旨在通过对现有研究的荟萃分析，比较青少年特发性脊柱侧凸（AIS）患者和健康受试者的步态分析结果。通过 Medline（通过 PubMed）、Cochrane、Scopus 和 Embase 数据库检索评估 AIS 发现的研究，包括时空参数（步行速度、步长、步频和站立相持续时间）、节段运动学（额状面、矢状面和横向骨盆运动）和肌电图变量（腰方肌、竖脊肌和臀中肌的电活动），并于 2000 年 1 月至 2020 年 5 月发表。两位作者独立提取数据，对于检索研究的入选标准存在任何分歧，通过共识解决。确定了六项比较研究，并随后进行了分析。结果发现，与健康对照组相比，AIS 患者的站立相和额状面骨盆运动明显减少。速度、步长、步频、矢状面骨盆运动和横向骨盆运动无显著差异。与健康受试者相比，AIS 组的腰方肌、竖脊肌和臀中肌的电活动持续时间显著增加。尽管存在异质性，但有限数量的荟萃分析显示，站立相和额状面骨盆运动减少，同时腰方肌、竖脊肌和臀中肌的激活时间延长。因此，需要进一步开展大规模、多中心研究来验证我们的结果。
