Abstract
INTRODUCTION
Leg length inequalities (LLI) are a common finding. Rasterstereography offers a non-invasive, contact-free and reliable method to detect the effects of LLIs on spinal posture and pelvic position.
MATERIALS AND METHODS
A total of 115 subjects were rasterstereographically examined during different artificially created leg length inequalities (5-15 mm) using a platform. The pelvic obliquity and torsion and the lateral and frontal deviation of the spine, as well as the surface rotation, were measured.
RESULTS
Changes in platform height led to an increase of the pelvic tilt and torsion. Only minor changes in the spinal posture were found by different simulated leg length inequalities.
CONCLUSIONS
Our study showed that there was a correlation between an artificial leg length inequality up to 15 mm and pelvic tilt or torsion, but only minor changes in the spinal posture were measured. Further studies should investigate the effects of greater leg length inequalities on spine and pelvis.
摘要
简介
腿长不等（LLI）是一种常见的现象。光栅立体摄影术提供了一种非侵入性、非接触和可靠的方法来检测 LLI 对脊柱姿势和骨盆位置的影响。
材料与方法
共对 115 名受试者在不同的人为创建的腿长不等（5-15mm）情况下使用平台进行了光栅立体摄影术检查。测量了骨盆倾斜和扭转以及脊柱的侧方和额状面偏斜，以及表面旋转。
结果
平台高度的变化导致骨盆倾斜和扭转增加。不同模拟的腿长不等仅导致脊柱姿势的轻微变化。
结论
我们的研究表明，人工腿长不等达 15mm 与骨盆倾斜或扭转之间存在相关性，但仅测量到脊柱姿势的轻微变化。进一步的研究应调查更大的腿长不等对脊柱和骨盆的影响。
