下肢外骨骼机器人辅助步行训练对脑卒中偏瘫患者步行能力的影响OA

Objective:To investigate the efficacy of lower-limb exoskeleton robotic-assisted gait training(RAGT)on improving the walking ability of stroke patients,thereby providing objective evidence for the optimization of clini-cal gait rehabilitation protocols.Methods:Totally,36 eligible stroke patients were randomly allocated to the RAGT group and the control group,with 18 participants in each group.Both groups received routine rehabilitation thera-py;additionally,the RAGT group underwent RAGT,while the control group received conventional gait training.The intervention duration was 2 weeks.Pre-and post-intervention assessments were conducted to evaluate the lower limb Brunnstrom stage,Functional Ambulation Category(FAC)score,Modified Barthel Index(MBI)score,and gait parameters(including walking speed,stride length,step width,toe out angle,and the proportion of single-step time contributed by the affected limb)in patients from both groups.Results:No statistically significant differences were found in all baseline characteristics between the two groups(P<0.05).After the intervention,both groups demonstrated significant improvements in lower limb Brunnstrom stage,FAC,MBI,walking speed,stride length,and the proportion of single-step time contributed by the affected limb compared with pre-intervention levels(P<0.05),while toe out angle was significantly reduced(P<0.05).Post-intervention intergroup comparisons revealed that the robot group had higher scores in lower limb Brunnstrom stage,walking speed,stride length,and the proportion of single-step time contributed by the affected limb than the control group(P<0.05),and the magnitude of reduction in toe out angle was greater in the robot group(P<0.05).Additionally,the robot group exhibited a significant reduction in step width after the intervention compared with baseline(P<0.05),but no significant intergroup difference was noted in this parameter.Conclusion:RAGT can effectively im-prove lower limb motor function and gait parameters in stroke patients,demonstrating potential clinical application value.
