To evaluate if the capacity to perform functional mobility activities change within the first year post-stroke using the Timed "Up and Go" Assessment of Biomechanical Strategies (TUG-ABS).
A cross-sectional study was conducted with thirty-eight stroke individuals. A motion analysis system was used during the Timed "Up and Go" (TUG) test to evaluate the following activities: sit-to-stand, gait, turn, and stand-to-sit. Kinematic variables related to each activity were obtained in addition to TUG-ABS scores. The ability to perform the activities was compared between subacute (up to 3 months post-stroke, n = 21) and chronic participants (4 to 12 months post-stroke, n = 17) using Mann-Whitney U tests (α= 5%).
Results were expressed as median difference (MD) and 95% confidence intervals (95% CI). TUG-ABS scores: Sit-to-stand (MD = 0, 95% CI = 0.0 to 1), gait (MD = 0, 95% CI = 0.0 to 1), stand-to-sit (MD = 0, 95% CI = 0.0 to 1), and total score (MD = 2.0, 95% CI = 0.0 to 6) were not different between groups. Subacute participants presented significant better scores during turn activity (MD = 2.0, 95% CI 0.0 to 2.0). All kinematic variables were not different between participants.
Capacity to perform functional activities was not different within the first year post-stroke, suggesting that biomechanical strategies are developed within the first three months following stroke.
使用 Timed "Up and Go" 评估生物力学策略（TUG-ABS）评估卒中后第一年患者的功能性移动能力是否发生变化。
本研究为横断面研究，共纳入 38 名卒中患者。在 Timed "Up and Go"（TUG）测试中使用运动分析系统评估以下活动：从坐到站、步态、转身和从站到站坐。除 TUG-ABS 评分外，还获得与每项活动相关的运动学变量。使用曼-惠特尼 U 检验（α=5%）比较亚急性（卒中后 1 个月内，n=21）和慢性（卒中后 4-12 个月，n=17）参与者之间的活动能力。
结果表示为中位数差值（MD）和 95%置信区间（95%CI）。TUG-ABS 评分：从坐到站（MD=0，95%CI=0.0-1）、步态（MD=0，95%CI=0.0-1）、从站到站坐（MD=0，95%CI=0.0-1）和总分（MD=2.0，95%CI=0.0-6）在组间无差异。亚急性组在转身活动中表现出明显更好的评分（MD=2.0，95%CI 0.0-2.0）。所有运动学变量在参与者之间均无差异。
卒中后一年内，功能性活动能力无差异，提示生物力学策略在卒中后三个月内发展。
