This study evaluated asymmetry of weight bearing on the lower limbs and the association between percentage weight bearing asymmetry (PWBA) and functional ambulation performance in ambulant stroke survivors. Participants were 53 stroke survivors (male = 35, female = 18) aged 40-86 years (mean=58.87; SD=9.21years) with hemiparesis. Weight bearing through the lower limbs in standing was assessed by two juxtaposed bathroom weighing scales while functional ambulation performance was evaluated with the Emory Functional Ambulation Profile (E-FAP). Data were summarized with mean and standard deviation and further analyzed using the Pearson product moment correlation at 0.05 alpha level. Participants bore 60.3% (SD =7.1%) of their body weights on the unaffected legs and had a mean PWBA of 20.8 % (SD=14.7%). There was a significant positive correlation (r = 0.675, p < 0.0001) between PWBA and total E-FAP scores of participants. PWBA could hence be used to monitor functional ambulation recovery in stroke survivors.
本研究评估了步行的中风幸存者双下肢负重的不对称性，以及负重不对称百分比（PWBA）与功能性步行表现之间的关联。研究对象为53例年龄在40 - 86岁（平均58.87岁；标准差9.21岁）的中风幸存者（男性35例，女性18例），均有偏瘫症状。通过两个并列的浴室体重秤评估站立时下肢的负重情况，同时使用埃默里功能性步行量表（E - FAP）评估功能性步行表现。数据用均值和标准差进行汇总，并在0.05的显著性水平下使用Pearson积差相关进行进一步分析。参与者在健侧下肢承受了60.3%（标准差 = 7.1%）的体重，平均PWBA为20.8%（标准差 = 14.7%）。参与者的PWBA与E - FAP总分之间存在显著正相关（r = 0.675，p < 0.0001）。因此，PWBA可用于监测中风幸存者功能性步行恢复情况。
