People with stroke have reduced walking activity. It is not known whether this deficit is due to a reduction in all aspects of walking activity or only in specific areas. Understanding specific walking activity deficits is necessary for the development of interventions that maximize improvements in activity after stroke.
The purpose of this study was to examine walking activity in people poststroke compared with older adults without disability.
A cross-sectional study was conducted.
Fifty-four participants poststroke and 18 older adults without disability wore a step activity monitor for 3 days. The descriptors of walking activity calculated included steps per day (SPD), bouts per day (BPD), steps per bout (SPB), total time walking per day (TTW), percentage of time walking per day (PTW), and frequency of short, medium, and long walking bouts.
Individuals classified as household and limited community ambulators (n=29) did not differ on any measure and were grouped (HHA-LCA group) for comparison with unlimited community ambulators (UCA group) (n=22) and with older adults without disability (n=14). The SPD, TTW, PTW, and BPD measurements were greatest in older adults and lowest in the HHA-LCA group. Seventy-two percent to 74% of all walking bouts were short, and this finding did not differ across groups. Walking in all categories (short, medium, and long) was lowest in the HHA-LCA group, greater in the UCA group, and greatest in older adults without disability.
Three days of walking activity were captured.
The specific descriptors of walking activity presented provide insight into walking deficits after stroke that cannot be ascertained by looking at steps per day alone. The deficits that were revealed could be addressed through appropriate exercise prescription, underscoring the need to analyze the structure of walking activity.
中风患者的步行活动减少。目前尚不清楚这种缺陷是由于所有步行活动方面的减少，还是仅在特定领域。了解具体的步行活动缺陷对于开发最大限度地提高中风后活动改善的干预措施是必要的。
本研究旨在比较中风后患者与无残疾的老年人的步行活动。
进行了一项横断面研究。
54 名中风后患者和 18 名无残疾的老年人佩戴了 3 天的计步器。计算的步行活动描述符包括每天的步数（SPD）、每天的回合数（BPD）、每回合的步数（SPB）、每天行走的总时间（TTW）、每天行走的时间百分比（PTW）以及短、中、长行走回合的频率。
被归类为家庭和有限社区步行者（n=29）的个体在任何指标上均无差异，并被分组（HHA-LCA 组）与无限制社区步行者（UCA 组）（n=22）和无残疾的老年人（n=14）进行比较。SPD、TTW、PTW 和 BPD 测量值在老年人中最高，在 HHA-LCA 组中最低。72%至 74%的所有步行回合都是短的，这一发现在不同组之间没有差异。在 HHA-LCA 组中，所有类别（短、中、长）的步行活动最低，在 UCA 组中较高，在无残疾的老年人中最高。
仅捕获了 3 天的步行活动。
呈现的特定步行活动描述符提供了中风后步行缺陷的深入了解，仅通过查看每天的步数无法确定这些缺陷。通过适当的运动处方可以解决所揭示的缺陷，强调了分析步行活动结构的必要性。
