Objective,2,To observe the effect of Tai Chi footwork on walking ability of hemiplegic patients following ischemic stroke based on three-dimensional gait analysis.,Methods,2,Sixty patients with hemiplegia after ischemic stroke were randomly divided into control group (,n,=30) and experimental group (,n,=30). The control group received conventional rehabilitation training, while the experimental group received standardized Tai Chi footwork training. The course of treatment in both groups was 30 days. The three-dimensional gait and motion analysis system was used to detect and evaluate patients’ kinematic parameters of time and space variables.,Results,2,①There was no drop-out case during the trail. ②In the experimental group, the stride time was shortened, the proportion of supporting phase of the healthy side reduced, and the proportion of swinging phase of the healthy side increased after treatment (,P,<,0.05), while there was no significant difference in the proportion of supporting phase and swinging phase of affected side before and after treatment(,P,>,0.05). In the control group, the stride time was shortened, the proportion of supporting phase of the healthy side reduced, the proportion of swinging phase of the healthy side increased, the proportion of supporting phase of the affected side increased, and the proportion of swinging phase of the affected side reduced after treatment(,P,<,0.05). After treatment, the stride time in the experimental group was significantly shorter than that in the control group, the proportion of supporting phase of the affected side was significantly lower than that in the control group, and the proportion of swinging phase of the affected side was significantly higher than that in the control group (,P,<,0.05). There was no significant difference in the proportion of supporting phase and swinging phase of healthy side between the two groups after treatment (,P,>,0.05). ③In the experiment group, the stride length was lengthened, the stride speed was accelerated, the stride width was shortened, and the step length of healthy and affected foot was lengthened after treatment (,P,<,0.05). In the control group, the stride length was lengthened, the stride speed was accelerated, the stride width was shortened, the step length of affected foot was lengthened (,P,<,0.05), and there was no significant difference in the step length of healthy foot before and after treatment (,P,>,0.05). After treatment, the stride length of the experimental group was significantly longer than that of the control group, the stride speed was significantly faster than that of the control group, and the stride width was significantly shorter than that of the control group (,P,<,0.05). There was no significant difference in the step length of healthy foot and affected foot between the two groups (,P,>,0.05).,Conclusion,2,Compared with conventional rehabilitation training, Tai Chi footwork training can significantly improve the overall walking ability of hemiplegic patients following ischemic stroke, and improve the supporting and swinging ability of the affected lower limbs.
