Background

Weight-bearing asymmetry biasing the non-paretic leg is common following stroke. However, little is known as to how lateropulsion impacts on the weight-bearing patterns adopted in standing by individuals following stroke.

Research Questions

(1) Are there differences in weight-bearing asymmetry patterns observed in standing in people with lateropulsion relative to healthy controls; (2) What is the relationship between weight-bearing asymmetry and clinical measures of lateropulsion and postural function; and (3) Are measures of weight-bearing asymmetry reliable between test occasions.

Methods

Thirty-three individuals with lateropulsion and 35 healthy controls participated in this study. For the participants with lateropulsion, weight-bearing asymmetry during standing tasks (measured using two Wii Balance Boards) and clinical measures of lateropulsion (Burke Lateropulsion Scale) and postural function (Postural Assessment Scale for Stroke) were assessed initially and fortnightly over eight weeks.

Results

Individuals with lateropulsion displayed marked weight-bearing asymmetry in standing compared to healthy controls. This asymmetry was predominantly towards their non-paretic leg when standing unsupported, and mixed presentation of weight-bearing asymmetry directions when standing with arm support. No significant correlations were observed between directional weight-bearing asymmetry and the Burke Lateropulsion Scale. A moderate correlation was found between absolute weight-bearing asymmetry for the stand with arm support task and the Postural Assessment Scale for Stroke (r = −0.608). The weight-bearing asymmetry variables for the standing with arm support task were found to be highly reliable between test occasions (ICC 0.915−0.972) and the standard error of measurement was 8.2%–9.3% body weight.

Significance

Individuals with lateropulsion following stroke demonstrate marked and varied patterns of asymmetry in standing. Weight-bearing asymmetry when standing with arm support may be an appropriate outcome measure for use with patients with lower functional abilities, including those with lateropulsion.

成人卒中后侧翻的站立负重不对称

背景

中风后,非瘫痪腿的负重不对称很常见。然而,对于中风后个人站立时侧向推力如何影响承重模式,我们知之甚少。

研究问题

(1) 与健康对照组相比,侧倾患者站立时所观察到的负重不对称模式是否存在差异;(2) 负重不对称性与侧推力和姿势功能的临床测量之间的关系是什么?(3) 承重不对称性的测量在测试场合之间是否可靠。

方法

33 名有侧向冲动的人和 35 名健康对照者参加了这项研究。对于有侧向运动的参与者,站立任务期间的负重不对称(使用两个 Wii 平衡板测量)和侧向运动的临床测量(伯克侧向运动量表)和姿势功能(中风姿势评估量表)在八周内进行了最初和每两周评估。

结果

与健康对照组相比,有侧向冲动的个体在站立时表现出明显的负重不对称。这种不对称主要是在没有支撑的情况下站立时他们的非瘫痪腿,以及在有手臂支撑的情况下站立时的负重不对称方向的混合表现。在定向负重不对称和伯克侧推量表之间没有观察到显着的相关性。发现手臂支撑任务的绝对负重不对称性与中风姿势评估量表之间存在中等相关性(r = -0.608)。发现手臂支撑站立任务的负重不对称变量在测试场合之间高度可靠(ICC 0.915-0.972),测量标准误差为 8.2%–9.3% 体重。

意义

中风后出现侧移的个体在站立时表现出明显和不同的不对称模式。手臂支撑站立时的负重不对称可能是用于功能较低的患者(包括侧推患者)的适当结果衡量标准。
