The aim of this study was to investigate the effects of an action observation training on balance and sit to walk in chronic stroke. Twenty-four chronic stroke patients participated in this study. Participants were randomly allocated to either the landscape imagery observation physical training group (LIOPT) or the action observation physical training group (AOPT). LIOPT observed a landscape picture for 2 min 30 s while the AOPT group observed related video recording. Both groups underwent a physical training session after the observation session for 12 min 30 s and the sessions were repeated twice a day, 3 times a week for 6 weeks. Outcome measures included Time Up and Go Test (TUG), Dynamic Gait Index (DGI), Weight Distribution Index (WDI), and limit of stability (LOS). Between-group and within-group comparisons were analyzed using the Mann-Whitney U test and Wilcoxon signed rank test, respectively. The AOPT and LIOPT groups have shown statistically significant differences in TUG, DGI, WDI, and LOS over time. However, no significant difference was observed in terms of TUG, DGI and WDI, but only in LOS between groups. These findings suggest that action observation training and physical training are effective to improve sit to walk and balance ability of chronic stroke patients.
本研究旨在探讨动作观察训练对慢性卒中患者平衡能力及从坐到走能力的影响。24名慢性卒中患者参与了本研究。参与者被随机分配至风景意象观察体育训练组（LIOPT）或动作观察体育训练组（AOPT）。LIOPT组观察一幅风景画2分30秒，而AOPT组观察相关视频记录。两组在观察期后均进行12分30秒的体育训练课程，且每天重复两次，每周3次，共6周。结果指标包括起立行走测试（TUG）、动态步态指数（DGI）、体重分布指数（WDI）和稳定性极限（LOS）。组间比较和组内比较分别采用曼-惠特尼U检验和威尔科克森符号秩检验进行分析。随着时间推移，AOPT组和LIOPT组在TUG、DGI、WDI和LOS方面均显示出统计学上的显著差异。然而，在TUG、DGI和WDI方面未观察到显著差异，仅在组间的LOS方面存在显著差异。这些发现表明，动作观察训练和体育训练对改善慢性卒中患者的从坐到走能力和平衡能力有效。
