What is the free-living physical activity of community-dwelling people with stroke compared with that of age-matched healthy controls?
A cross-sectional observational study.
42 people with stroke and 21 age-matched healthy controls aged 52 to 87 years living in Sydney, Australia.
Free-living physical activity was measured using the Intelligent Device for Energy Expenditure and Activity (IDEEA) and reported as duration (time on feet in min) and frequency (activity counts).
People with stroke spent 79 (95% CI 20 to 138) fewer min on their feet and performed 5308 (95% CI 3171 to 7445) fewer activity counts than healthy controls. The observation period of the free-living physical activity of stroke survivors was significantly less than that of the healthy controls. Data adjusted to a fixed observation period (12 hr) showed no relative difference in time on feet between the groups (mean difference 36 min, 95% CI -27 to 99) but that people after stroke still had relatively fewer activity counts than healthy controls (mean difference 4062 counts, 95% CI 1787 to 6337).
The reduction in physical activity after stroke is not primarily because of a decrease in the time spent being active but rather a decrease in frequency of activity during that time. Future research into physical activity after stroke needs to consider energy expenditure because stroke survivors exhibit a reduced frequency of physical activity due to the nature of their impairments.
与年龄匹配的健康对照者相比，社区居住的脑卒中患者的自由活动体力活动如何？
横断面观察性研究。
42 名年龄在 52 至 87 岁之间居住在澳大利亚悉尼的脑卒中患者和 21 名年龄匹配的健康对照者。
使用智能能量消耗和活动设备（IDEEA）测量自由活动体力活动，并以时间（站立时间，分钟）和频率（活动计数）报告。
与健康对照者相比，脑卒中患者站立时间少 79 分钟（95%CI 20 至 138），活动计数少 5308 次（95%CI 3171 至 7445）。脑卒中幸存者的自由活动体力活动观察期明显短于健康对照者。将数据调整为固定观察期（12 小时）后，两组之间的站立时间无相对差异（平均差异 36 分钟，95%CI -27 至 99），但脑卒中后患者的活动计数仍明显少于健康对照者（平均差异 4062 次，95%CI 1787 至 6337）。
脑卒中后体力活动减少主要不是因为活跃时间减少，而是因为在此期间活动频率降低。未来的脑卒中后体力活动研究需要考虑能量消耗，因为脑卒中幸存者由于其损伤的性质，活动频率降低。
