项目摘要

The purpose of this study was to investigate relations with the deflection characteristic of the body center of mass at landing of the backward stepping and the joint moment, and range of motion of the spinal column in the elderly.The results of this study showed a significant negative correlation between the amount of thebody center of mass and ankle plantar flexion moments in the elderly group. Furthermore, significant negative correlation was observed between the extension range of motion from the 11th thoracic vertebra to the 12th thoracic vertebra and deflection of the body center of mass at the landing phase of the backward stepping reaction.This study suggests that, for controlling deflection of the body center of mass at the landing phase, extension range of motion in the transition region between the thoracic vertebra and lumbar vertebrae take an important role.

本研究旨在探讨老年人后蹬着地时身体重心的偏转特征与关节力矩、脊柱活动度的关系，结果表明：老年人后蹬着地时身体重心的大小与踝关节跖屈力矩呈显著负相关。此外，从第11胸椎到第12胸椎的伸展运动范围与后蹬反应落地相的身体质心偏转呈显著负相关，本研究表明，为了控制落地相身体质心的偏转，在胸椎和腰椎之间的过渡区域中，活动范围的延伸起着重要作用。
