[Purpose] The purpose of this study was to compare the center of mass during sit-to-stand and stand-to-sit activities in the timed up and go test between healthy subjects and patients with stroke. [Subjects and Methods] Thirty healthy participants and thirty patients with stroke volunteered for this study. Acceleration of the center of mass was measured using a wireless tri-axial accelerometer during sit-to-stand and stand-to-sit activities in the timed up and go test. Accelerometer data were analyzed using BTS G-studio software. [Results] The phase duration was significantly longer and the anterior-posterior, mediolateral, and vertical acceleration ranges were significantly lower during sit-to-stand for patients with stroke than for healthy controls. Further, phase duration and the mediolateral acceleration range during stand-to-sit differed significantly between healthy controls and subjects with stroke. [Conclusions] During training for the sit-to-stand activity, the focus should be all three balance dimensions, but during training for the stand-to-sit activity, the focus should be on improving mediolateral balance and asymmetrical foot positioning should be recommended.
[目的]本研究旨在比较健康受试者与中风患者在定时起立行走测试中从坐起到站立以及从站立到坐下活动期间的质心情况。[受试者与方法]30名健康参与者和30名中风患者自愿参与本研究。在定时起立行走测试中，使用无线三轴加速度计测量从坐起到站立以及从站立到坐下活动期间的质心加速度。加速度计数据使用BTS G-studio软件进行分析。[结果]中风患者从坐起到站立的阶段持续时间显著更长，前后、内外侧和垂直加速度范围显著低于健康对照组。此外，健康对照组与中风受试者从站立到坐下的阶段持续时间和内外侧加速度范围存在显著差异。[结论]在坐立活动训练期间，应关注所有三个平衡维度，但在站立到坐下活动训练期间，应着重改善内外侧平衡，并建议采用不对称的足部姿势。
