Background

The relationship between maximum and comfortable gait speed in individuals with mild to moderate disability in the chronic phase of stroke is unknown.

Objective

This study examines the relationship between comfortable and maximum gait speed in individuals with chronic stroke and whether the relationship differ from that seen in a community-dwelling elderly population. Further, we investigate the influence of age, gender, time post-stroke and degree of disability on gait speed.

Materials and methods

Gait speed was measured using the 10-meter walk test (10MWT) and the 30-meter walk test (30MWT) in 104 older individuals with chronic stroke and 154 community-dwelling controls, respectively.

Results

We found that the maximum gait speed in individuals with stroke could be estimated by multiplying the comfortable speed by 1.41. This relationship differed significantly from that of the control group, for which the corresponding factor was 1.20. In the stroke group, age, gender and time post-stroke did not affect the relationship, whereas the degree of disability was negatively correlated with maximum speed - but not when included in the multiple analysis. In the community-dwelling population, higher age and female gender had a negative relationship with maximum gait speed. When correcting for those parameters, the coefficient was 1.07.

Conclusions

The maximum gait speed in the chronic phase of stroke can be estimated by multiplying the individual's comfortable gait speed by 1.41. This estimation is not impacted by age, gender, degree of disability and time since stroke. A similar but weaker relationship can be seen in the community-dwelling controls.

慢性中风和社区住宅控制患者的舒适和最大步态速度

背景

中风慢性期轻度至中度残疾个体的最大和舒适步态速度之间的关系尚不清楚。

客观的

本研究调查了慢性卒中患者的舒适步态和最大步态速度之间的关系，以及这种关系是否与社区老年人群中的关系不同。此外，我们调查了年龄、性别、中风后时间和残疾程度对步态速度的影响。

材料和方法

步态速度分别使用 10 米步行测试 (10MWT) 和 30 米步行测试 (30MWT) 在 104 名患有慢性中风的老年人和 154 名社区居民中进行测量。

结果

我们发现中风患者的最大步态速度可以通过将舒适速度乘以 1.41 来估计。这种关系与对照组的关系显着不同，对照组的相应因子为 1.20。在中风组中，年龄、性别和中风后时间不影响这种关系，而残疾程度与最大速度呈负相关 - 但当包含在多重分析中时则不然。在社区居民中，较高的年龄和女性性别与最大步态速度呈负相关。校正这些参数时，系数为 1.07。

结论

中风慢性期的最大步态速度可以通过将个人的舒适步态速度乘以 1.41 来估计。这种估计不受年龄、性别、残疾程度和中风后时间的影响。在社区住宅控制中可以看到类似但较弱的关系。
