最近的研究表明，全身振动改善了中风患者的姿势和步态控制。患有退行性小脑疾病的患者患有共济失调步态，其特征也是步态模式的变化。我们的兴趣是测试全身振动作为小脑患者康复治疗的一种方法，并使用动态测试来评估治疗的成功。本研究的目的是介绍一种量化主动自愿踏步期间运动动力学的方法，该方法导致体重转移受试者必须执行从双脚分开的位置到双脚并排位置的一步，然后再回来。本研究的目的是介绍一种量化运动动力学的方法本研究通过分析压力轨迹的中心，自动识别动态阶段的时间。本研究仅计算了主动运动的平均速度、加速度和挺举的时间流量。本研究证明，挺举为康复和训练中步态的改善提供了一种灵敏的措施(C)2010爱思唯尔B V版权所有
Recent studies have shown that whole-body vibration improves posture and gait control in stroke patients Patients with degenerative cerebellar disease suffer from ataxic gait also which is characterised by the variation of gait pattern Our interest is to test whole-body vibration as a method for rehabilitation treatment in cerebellar patients and to assess the success of the treatment using dynamic tests The aim of this study was to introduce a method for quantifying movement dynamics during an active voluntary sidestep that results in a body-weight-transfer Subjects had to perform a step from a feet-apart-position to a feet-together-position and back again The algorithms presented in this study allow automatic identification of the timing of the dynamic phases by analysing the centre of pressure trajectory For this study the time flow of averaged speed acceleration and jerk was calculated for the active movement only This study demonstrates that jerk provides a sensitive measure for the improvement in gait in rehabilitation and during training (C) 2010 Elsevier B V All rights reserved
