Abstract

Purpose: Physical activity within the hospital post-stroke is recommended for cardiovascular and musculoskeletal health, but no studies have examined cerebrovascular health. We hypothesized individuals who walked farther distances (FARhigh) during the acute phase of stroke recovery in a hospital setting would have a higher resting middle cerebral artery blood velocity (MCAv) and a greater cerebrovascular response (CVR) to moderate-intensity exercise at 3-months post-stroke, compared to individuals who walked shorter distances (FARlow).

Methods: At 3-month post-stroke, we recorded 90-seconds of resting baseline (BL) MCAv followed by 6-minutes of moderate-intensity exercise. We calculated CVR as the change in MCAv from BL to steady-state exercise. We retrospectively collected farthest distance walked within the hospital post-stroke from the electronic medical record. Participants were classified as FARhigh or FARlow based on average farthest walking distance.

Results: Twenty participants completed the study, age 63 (15) years. BL MCAv was not different between groups (p = 0.07). In comparison to FARlow, we report a higher CVR in FARhigh's ipsilesional ( $\bar{x}$ = 7.38 (5.42) vs $\bar{x}$ = 2.19 (3.53), p = 0.02) and contralesional hemisphere ( $\bar{x}$ = 8.15 (6.37) vs $\bar{x}$ = 2.06 (4.76), p = 0.04).

Conclusions: Physical activity during the hospital stay post-stroke may support cerebrovascular health after discharge. Prospective studies are needed to support this finding.

急性脑卒中住院期间步行活动与脑血管健康的二次分析。

目的:中风后医院内的身体活动被推荐用于心血管和肌肉骨骼健康，但没有研究检查脑血管健康。我们假设，在医院中风恢复的急性期，与行走距离较短的个体(FARlow)相比，行走距离较远的个体(FARhigh)在中风后3个月时，对中等强度运动的静息大脑中动脉血流速度(MCAv)和脑血管反应(CVR)更高。方法:在中风后3个月，我们记录了90秒的静息基线(BL) MCAv，然后进行了6分钟的中等强度运动。我们计算CVR为MCAv从BL到稳态运动的变化。我们回顾性地从电子病历中收集脑卒中后在医院内行走的最远距离。参与者根据平均最远步行距离被划分为FARhigh或FARlow。结果:20名参与者完成了研究，年龄63(15)岁。各组间BL MCAv差异无统计学意义(p = 0.07)。与FARlow相比，我们报告了FARhigh的同侧半球(x¯= 7.38 (5.42)vs x¯= 2.19 (3.53)，p = 0.02)和对侧半球(x¯= 8.15 (6.37)vs x¯= 2.06 (4.76)，p = 0.04)的CVR更高。结论:脑卒中患者住院期间的体育活动有助于其出院后的脑血管健康。需要前瞻性研究来支持这一发现。
