This study investigated the effectiveness of Ai Chi compared to conventional water-based exercise on balance performance in individuals with chronic stroke. A total of 20 individuals with chronic stroke were randomly allocated to receive either Ai Chi or conventional water-based exercise for 60 min/time, 3 times/week, and a total of 6 weeks. Balance performance assessed by limit of stability (LOS) test and Berg balance scale (BBS). Fugl-Meyer assessment (FMA) and gait performance were documented for lower extremity movement control and walking ability, respectively. Excursion and movement velocity in LOS test was significantly increased in anteroposterior axis after receiving Ai Chi (p = 0.005 for excursion, p = 0.013 for velocity) but not conventional water-based exercise. In particular, the improvement of endpoint excursion in the Ai Chi group has significant inter-group difference (p = 0.001). Both groups showed significant improvement in BBS and FMA yet the Ai Chi group demonstrated significantly better results than control group (p = 0.025). Ai Chi is feasible for balance training in stroke, and is able to improve weight shifting in anteroposterior axis, functional balance, and lower extremity control as compared to conventional water-based exercise.

艾奇对慢性卒中患者平衡的影响：一项随机对照试验。

这项研究调查了与传统的水基运动相比，爱驰对慢性卒中个体平衡能力的有效性。随机分配总共20例慢性中风患者，以60分钟/次，3次/周，共6周的时间接受艾奇或常规水基运动。通过稳定性极限（LOS）测试和伯格平衡量表（BBS）评估平衡性能。分别记录了下肢运动控制和步行能力的Fugl-Meyer评估（FMA）和步态表现。接受爱知后，LOS测试中前后轴的运动和运动速度显着增加（运动时p = 0.005，运动时p = 0.013），而常规水上运动则没有。特别是，爱知组的终点偏移改善具有显着的组间差异（p = 0.001）。两组均显示出BBS和FMA的显着改善，而爱知组显示出明显优于对照组的结果（p = 0.025）。与传统的水上运动相比，Ai Chi在中风的平衡训练中是可行的，并且能够改善前后轴的重量转移，功能平衡和下肢控制。
