To determine whether there are differences in arm, leg and trunk activity measured by acceleration between weekdays and weekends in people undergoing rehabilitation in the subacute stage after stroke.
Cross-sectional study.
Twenty-eight individuals with stroke (mean age 55.4 years; severe to mild impairment) and 10 healthy controls.
A set of 5 3-axial accelerometers were used on the trunk, wrists and ankles during 2 48-h sessions at weekdays and over a weekend. Day-time acceleration raw data were expressed as the signal magnitude area. Asymmetry between the affected and less-affected limb was calculated as a ratio.
Participants with stroke used their both arms and legs less at weekends than on weekdays (p< 0.05, effect size 0.32-0.57). Asymmetry between the affected and less-affected arm was greater at weekends (p < 0.05, effect size 0.32). All activity measures, apart from the less-affected arm on weekdays, were lower in stroke compared with controls (p < 0.05, effect size 0.4-0.8). No statistically significant differences were detected between weekday and weekend activity for the control group. One-third of participants perceived the trunk sensor as inconvenient to wear.
Increased focus needs to be applied on activities carried out during weekends at rehabilitation wards.
确定在亚急性期脑卒中康复患者中，手臂、腿部和躯干的加速度活动在工作日和周末是否存在差异。
横断面研究。
28 名脑卒中患者（平均年龄 55.4 岁；严重至轻度功能障碍）和 10 名健康对照者。
在 2 个 48 小时的工作日和周末期间，在躯干、手腕和脚踝上使用了一组 5 个三轴加速度计。日间加速度原始数据表示为信号幅度面积。受影响和较少受影响肢体之间的不对称性作为比率进行计算。
与工作日相比，脑卒中患者在周末使用双臂和双腿的频率较低（p<0.05，效应大小为 0.32-0.57）。周末时，受影响手臂与未受影响手臂之间的不对称性更大（p<0.05，效应大小为 0.32）。与对照组相比，所有活动测量值（除了工作日的非受影响手臂）均较低（p<0.05，效应大小为 0.4-0.8）。对照组在工作日和周末之间的活动无统计学差异。三分之一的参与者认为躯干传感器佩戴不方便。
需要更加关注康复病房周末期间进行的活动。
