Effect Of Augmented Reality Walking Training On Postural Control After Stroke

Objective:To investigate the effects of augmented reality walking on postural control in stroke patients.Methods:This study was a randomized,single-blind,controlled trial of 24 patients with a convalescent stroke.They were randomized into a trial group and a control group using EXCEL software,with 12 in each group.The control group accepted traditional walking training on the basis of routine rehabilitation training.The experimental group accepted augmented reality walking training on the basis of routine rehabilitation training.The training time was 5 times a week for 40 minutes for 4 weeks.The vital signs of the subjects were measured before and after the test,and the risk of walking and falling was assessed using a time up and go(TUGT)and a functional ambulation category scale(FAC).Lower limb motor function was assessed using the Fugle-Meyer assessment(FMA).Posture control stability is assessed using the Neurocom Balance Manager.The statistical data of the test data were analyzed by SPSS20.0.The rank sum test was used for the data that did not conform to the normal distribution.The independent sample t test was used for the comparison between the data groups that met the normal distribution.The paired t test was used for comparison within the group,p<0.05.Indicates that there is a significant difference in statistical results.Results:1.The time of completion of TUGT in the experimental group and the control group was significantly shortened(p<0.05),and there was significant difference between the groups(p<0.05).The FMA scores of the experimental group and the control group were significantly increased after training(p<0.05),and there was a significant difference between the groups(p<0.05).The FAC score of the experimental group was significantly increased after training(p<0.05),and there was no significant increase in the control group.There was no significant difference between the groups.2.in the sensory organization test,there was no significant difference with static balance indicator between the experimental group and the control group.In the Dynamic balance index,balance strategy score SOT4(blinking,plantar support face-down swing)test group and control group were significantly improved after training(p<0.05);SOT 5(closed eye,foot support)The surface of the test group was improved after training compared with that before training,and there was a significant difference(p<0.05).The SOT 3(blinking,visual environment sway)of the center of gravity of the body before and after the swing after the training group was less than the pre-training swing amplitude,there was a significant difference(p <0.05);SOT 6(blinking,visual environment shaking,foot)The bottom support swings under the surface.The training group has a smaller amplitude than the pre-training swing after training,and there is a significant difference(p<0.05)and there is a significant difference between the groups(p<0.05).3.In the motor control test,the reaction time of the test group and the control group was shorter than that of the control group before training,and there was a significant difference(p<0.05).The time of the foot support surface of the experimental group was significantly shorter than that before the training,and there was a significant difference(p<0.05).4.In the adaption test,the test results of the experimental group and the control group showed an improvement trend after training,but there was no significant difference between the comparison within the group and the comparison between the groups.5.In the weight symmetry test,when the knee flexion was 0°,the difference in the weight-bearing ratio of the lower limbs in the experimental group was lower than that before the training,there was a significant difference(p<0.05)and there was a significant difference between the groups(p< 0.05).Conclusion:1.Compared with regular walking training,Augmented Reality Walking Training can more effectively improve the walking function of stroke recovery patients and reduce the risk of falls.2.Augmented reality walking training can effectively improve the dynamic balance ability of patients with stroke recovery and improve posture stability.3.Augmented reality walking training is a safe and effective rehabilitation training method,which is worthy of clinical promotion.
