Observational studies demonstrate low levels of physical activity during inpatient stroke rehabilitation. There are no prior studies that have objectively measured sedentary time on the acute stroke unit and whether sedentary time is related to functional outcomes. The purpose of this study was to characterize sedentary time after acute stroke and determine whether there is a relationship to functional performance at discharge.
Thirty-two individuals (18 men; 56.5 ± 12.7 years) with acute stroke were enrolled within 48 hours of hospital admission. An accelerometer was placed on the stroke-affected ankle to measure 24-hour activity and was worn for 4 days or until discharge from the hospital. Performance of activities of daily living, walking endurance, and functional mobility were assessed using the Physical Performance Test, Six-Minute Walk Test, and Timed Up and Go, respectively.
Mean percent time spent sedentary was 93.9 ± 4.1% and percent time in light activity was 5.1 ± 2.4%. When controlling for baseline performance, the mean time spent sedentary per day was significantly related to Physical Performance Test performance at discharge (r = -0.37; P = .05), but not the Six-Minute Walk Test or Timed Up and Go.
Patients with acute stroke were sedentary most of their hospital stay. To minimize the potential negative effects of inactivity, our data suggest that there should be greater emphasis on increasing physical activity during the hospital stay.Video Abstract Available for more insights from the authors (Supplemental Digital Content 1, http://links.lww.com/JNPT/A101).
观察性研究表明，住院期间的中风康复期身体活动水平较低。此前尚无研究客观测量急性中风病房中的久坐时间，以及久坐时间是否与功能预后相关。本研究的目的是描述急性中风后的久坐时间特征，并确定其与出院时功能表现之间是否存在关联。
32例急性中风患者（18名男性；年龄56.5±12.7岁）在入院48小时内入组。将加速度计置于中风患侧脚踝以测量24小时活动情况，佩戴4天或直至出院。分别采用体能测试、六分钟步行测试和计时起立行走测试评估日常生活活动能力、步行耐力和功能移动性。
平均久坐时间百分比为93.9±4.1%，轻度活动时间百分比为5.1±2.4%。在控制基线表现后，每天的平均久坐时间与出院时的体能测试表现显著相关（r = -0.37；P = 0.05），但与六分钟步行测试或计时起立行走测试无关。
急性中风患者在住院期间大部分时间处于久坐状态。为尽量减少不活动的潜在负面影响，我们的数据表明，住院期间应更加强调增加身体活动。可观看视频摘要以获取作者更多见解（补充数字内容1，http://links.lww.com/JNPT/A101）。
