Abstract：
Staircases are a frequently encountered obstacle in daily life, requiring individuals to navigate ascending and descending movements that place additional demands on the trunk and lower limbs compared to walking on level surfaces. Therefore, it is crucial to examine the biomechanical characteristics of the trunk and lower limbs in individuals with scoliosis during stair activity. The aim of this study was to investigate the biomechanical differences in trunk and lower limbs during daily stair activities between patients with scoliosis and a healthy population. Additionally, the study aimed to explore the relationship between trunk abnormalities and lower limb biomechanics, providing a clinical and objective assessment basis for scoliosis. The Qualisys system, based in Gothenburg, Sweden, was employed for data collection in this study, with a sampling frequency of 150 Hz. It captured the kinematics of the trunk and lower limbs, as well as the kinetics of the lower limbs during stair ascent and descent for both the 28 individuals with scoliosis and the 28 control participants. The results indicate that scoliosis patients demonstrated significantly higher asymmetry compared to the control group in various measures during ascent and decent. These include different parts of kinematics and kinetics. Scoliosis patients demonstrate noticeable variations in their movement patterns compared to the healthy population when engaging in stair activities. Specifically, during stair ascent, scoliosis patients exhibit a seemingly more rigid movement pattern, whereas descent is characterized by an unstable pattern.
摘要：
楼梯是日常生活中经常遇到的障碍,与在水平面上行走相比，要求个人导航上升和下降运动对躯干和下肢有额外的要求。因此,研究脊柱侧凸患者在楼梯活动期间躯干和下肢的生物力学特征是至关重要的。这项研究的目的是调查脊柱侧凸患者与健康人群在日常楼梯活动中躯干和下肢的生物力学差异。此外,本研究旨在探讨躯干异常与下肢生物力学的关系,为脊柱侧凸的临床和客观评估提供依据。Qualisys系统，总部设在哥德堡,瑞典,在这项研究中用于数据收集，150Hz的采样频率。它捕获了躯干和下肢的运动学，以及28名脊柱侧凸患者和28名对照参与者在楼梯上升和下降过程中下肢的动力学。结果表明，在上升和体面的各种措施中，脊柱侧弯患者的不对称性明显高于对照组。这些包括运动学和动力学的不同部分。与从事楼梯活动的健康人群相比，脊柱侧弯患者的运动方式表现出明显的变化。具体来说,在楼梯上升期间，脊柱侧弯患者表现出看似更僵硬的运动模式，而下降的特征是不稳定的模式。
