| Objective:To explore the rehabilitation effect of lower limb rehabilitation robot assisted gait training on patients with chronic stroke.Methods:The 15 patients with chronic stroke treated in the Department of Rehabilitation Medicine,the First Affiliated Hospital of Chongqing Medical University from September 2017 to August 2019 were collected.These patients were given robot-assisted gait training for 6 weeks.The differences of gait parameters,spatiotemporal asymmetries,total score and score of each item of Barthel index were analyzed before and after 6weeks training.Results:Finally,12 patients completed the trial.After 6 weeks of robot assisted gait training,the gait parameters of patients with chronic stroke were improved.The cadence,stride length,velocity,step length of the affected leg,step length of the healthy leg were significantly increased as compared with baseline(P<0.05).The stride time and the double-support time were significantly shorter than baseline(P<0.05).The stance phase of the affected leg was shortened(P<0.05),and the swing phase of theaffected leg was prolonged(P<0.05).While the stance phase and swing phase of the healthy leg had no significant difference compared with baseline(P>0.05).The ratio of step length and the ratio of swing phase of both lower limbs had no significant difference compared with baseline(P>0.05).The total score of Barthel index was significantly higher than that before training(P<0.05).Among the items,the scores of bathing,walking on flat ground and going up and down stairs were higher than baseline,and the difference was statistically significant(P<0.05).Conclusions:Robot-assisted gait training can effectively improve the walking ability and activities of daily living of patients with chronic stroke,but the improvement of spatiotemporal asymmetries is not significant.Whether the spatiotemporal asymmetries can be improved by adjusting the robot equipment parameters needs to be further studied. |
