There have been few reports examining changes in physical activity (PA) after revascularization of lower extremities from the perspective of physical function at discharge. The purpose of this study was to clarify the effects of physical function before discharge on the amount of PA after discharge in patients who underwent revascularization.
The subjects were 34 Fontaine class II patients admitted for elective surgical revascularization or endovascular treatment at two hospitals from September 2017 to October 2019. Triaxial accelerometers were used to measure changes in sedentary behavior (SB) before admission and 1 month after discharge. Multiple regression analysis was performed on the 6-min walking distance (6MWD) at the time of discharge and the change in SB 1 month after discharge; the cutoff value was calculated from the receiver operating characteristic (ROC) curve.
SB 1 month after discharge significantly decreased in the decreased SB group compared to the increased SB group (575.5 [400-745.2] vs. 649.5 [453.8-809.2], p <0.01). ROC curve was plotted with SB increase/decrease as the dependent variable and 6MWD at discharge as the independent variable; the cutoff value was 357.5 m.
6MWD measurement at discharge may help predict changes in SB after discharge.
从出院时的身体功能角度来看，关于下肢血运重建后体力活动（PA）变化的报道较少。本研究旨在阐明出院前身体功能对出院后 PA 量的影响。
本研究的对象为 2017 年 9 月至 2019 年 10 月在两家医院因择期手术血管重建或血管内治疗而入院的 34 例 Fontaine Ⅱ级患者。使用三轴加速度计测量入院前和出院后 1 个月的久坐行为（SB）变化。对出院时的 6 分钟步行距离（6MWD）和出院后 1 个月 SB 的变化进行多元回归分析；从接收者操作特征（ROC）曲线计算出截断值。
与 SB 增加组相比，SB 减少组出院后 1 个月的 SB 显著减少（575.5[400-745.2] vs. 649.5[453.8-809.2]，p<0.01）。以 SB 增加/减少为因变量，以出院时的 6MWD 为自变量绘制 ROC 曲线；截断值为 357.5m。
出院时的 6MWD 测量值可能有助于预测出院后 SB 的变化。
