To explore the movement patterns utilized by persons post stroke from the simultaneous perspective of pelvic and limb loading with the path of centre of mass during the movement transitions sit to stand and stand to sit.
A descriptive pilot study where kinetic and kinematic data were collected and compared between the contribution made by the less affected versus more affected lower limb and trunk during sit to stand and stand to sit following stroke. Movement analysis was undertaken using force-plates and a 3D VICON motion capture system.
Data were successfully collected on nine subjects of whom four presented with left side more affected and eight were male. Two patterns were demonstrated for pelvic loading, four patterns for limb loading and five patterns for deviation of centre of mass. There were no consistent patterns of movement demonstrated dependent upon the more or less affected side. There was no consistent relationship between pelvic and limb loading and deviation of centre of mass throughout the movement phases.
In contrast to assumptions often made with respect to limb loading, we found large variability in movement patterns utilized by person's with a hemiparetic presentation during sit to stand and stand to sit. The findings suggest that movement problems encountered by persons post-stroke are complex and identifies limitations with respect to current measurement techniques.
从骨盆和肢体负荷以及运动转换（从坐到站和从站到坐）过程中质心轨迹的同步角度，探讨中风后患者所采用的运动模式。
一项描述性初步研究，收集并比较了中风后从坐到站和从站到坐过程中，患侧程度较轻与较重的下肢及躯干所做贡献的动力学和运动学数据。使用测力板和三维VICON运动捕捉系统进行运动分析。
成功收集了9名受试者的数据，其中4名左侧受影响更严重，8名男性。骨盆负荷呈现出两种模式，肢体负荷呈现出四种模式，质心偏移呈现出五种模式。未表现出依赖于患侧程度轻重的一致运动模式。在整个运动阶段，骨盆和肢体负荷与质心偏移之间没有一致的关系。
与通常关于肢体负荷的假设相反，我们发现偏瘫患者在从坐到站和从站到坐过程中所采用的运动模式存在很大差异。研究结果表明，中风后患者遇到的运动问题很复杂，并指出了当前测量技术的局限性。
