中风后偏瘫患者在行走过程中通常会经历瘫痪肢体前向地面反作用力(即肢体推进力)的下降。步态速度和步行能力已经独立地与中风患者的偏瘫肢体推进、生活质量和参与度相关。然而，目前尚不清楚潜在的肢体机制(即推进)在多大程度上影响了人们对生活质量和参与程度的看法。因此，我们试图确定步态中肢体推进对中风后患者的生活质量和参与度的影响。这项研究是对步态再训练随机对照试验中个体的二次分析。在训练前和训练后6周，评估步速、步行能力、肢体推进力、卒中影响评分和平均每日步数。采用Pearson和Spearman相关分析方法对40名受试者的训练前数据进行横断面分析，以评估肢体推进(瘫痪肢体推进与总推进之比)与步速、步态能力、生活质量知觉领域和平均每日步数之间的潜在关系。部分相关用于控制步态速度。31个人接受了同样关系的纵向评估。观察两组在步速、步行能力、生活质量等方面的训练效果。然而，在控制步态速度后，我们在横断面和纵向分析中没有观察到显著的相关性(p≤0.05)。在控制了步态速度的影响后，偏瘫肢体推进与感知的生活质量或参与度没有直接关系。虽然肢体推进可能不会对参与者的感知生活质量产生直接影响，但它似乎是提高步态表现的一个重要因素，因此在可行的情况下，可能对康复治疗的目标很重要。
Individuals with hemiparesis following stroke often experience a decline in the paretic limb’s anteriorly directed ground reaction force during walking (i.e., limb propulsive force). Gait speed and walking capacity have been independently associated with paretic limb propulsion, quality of life, and participation in people with stroke. However, it is unclear as to the extent that underlying limb mechanics (i.e., propulsion) play in influencing perceptions of quality of life and participation. We therefore sought to determine the role of limb propulsion during gait on the perception of quality of life and participation in people following stroke. This study is a secondary analysis of individuals involved in a gait retraining randomized control trial. Gait speed, walking capacity, limb propulsion, Stroke Impact Scale, and average daily step counts were assessed prior to and following 6 weeks of training. The pre-training data from 40 individuals were analyzed cross-sectionally using Pearson and Spearman correlations, to evaluate the potential relationship between limb propulsion (ratio of paretic limb propulsion to total propulsion) with gait speed, gait capacity, perceived quality of life domains, and average daily step counts. Partial correlations were used to control for gait speed. Thirty-one individuals were assessed longitudinally for the same relationships. We observed a training effect for gait speed, walking capacity, and some quality of life measures. However, after controlling for gait speed, we observed no significant (p≤0.05) correlations in the cross-sectional and longitudinal analyses. After controlling for the influence of gait speed, paretic limb propulsion is not directly related to perceived quality of life or participation. Although limb propulsion may not have a direct effect on participant’s perceived quality of life, it appears to be an important factor to enhance gait performance, and therefore may be important to target in rehabilitation, when feasible.
