摘要

非典型矢状脊柱-骨盆排列与加重腰痛（LBP）相关。本研究探讨了通过改变腰椎前凸（LL）模拟矢状椎盂对准对行走时腰椎接触力的影响。开发了一个带有定制腰椎关节的全身OpenSim模型，以估计18名健康参与者自行选择的快速步行步态的腰椎负荷。行走时受限的LL增强了椎体压缩和剪切力以及椎体压缩。过量的LL增加了椎体剪力、小关节和L5/S1椎体的压缩，可能进展为不同类型的下腰痛。

Understanding the effect of lumbar lordosis angle on vertebral load distribution during walking.

Atypical sagittal spinopelvic alignment is correlated with exacerbating lower back pain (LBP). This study investigated the effects of simulated sagittal spinopelvic alignment via altered lumbar lordosis (LL) on lumbar vertebral contact forces during walking. A full-body OpenSim model with custom lumbar joints was developed to estimate lumbar vertebral loads for self-selected speed walking gaits of 18 healthy participants. Limited LL during walking augmented the resultant vertebral compressive and shear forces, and vertebral body compression. Excessive LL increased resultant vertebral shear forces, compression at facet joints and L5/S1 vertebral body, potentially progressing to different types of LBP.

期刊介绍： The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
