三维步态分析训练辅助治疗对老年脑卒中后偏瘫患者膝过伸的影响研究

Study on the Effect of Three-dimensional Gait Analysis Training-assisted Therapy on Knee Hyperextension in Elderly Post-stroke Hemiplegic Patients

目的:探讨三维步态分析训练辅助治疗对老年脑卒中后偏瘫患者膝过伸的影响。方法:选取2021年1月—2023年12月无锡市康复医院收治的90例老年脑卒中后偏瘫患者作为研究对象,以随机数表法均分为对照组和研究组,每组各45例。对照组患者应用常规康复训练,研究组患者采取三维步态分析训练。对比两组患者下肢运动功能、平衡功能、步态时空参数情况。结果:干预后,两组患者简式运动功能评分量表(FMA)、Berg量表(BBS)评分高于干预前,差异有统计学意义(P<0.05);干预后,两组患者膝过伸次数低于干预前,差异有统计学意义(P<0.05);干预后,两组患者步频、步幅、步速、患侧摆动时间高于干预前,差异有统计学意义(P<0.05);干预后,两组患者步行周期、患侧支撑时间、双支撑时间短于干预前,差异有统计学意义(P<0.05)。结论:三维步态分析训练辅助治疗应用于老年脑卒中后偏瘫患者中可提升其下肢运动功能及平衡功能,有效缓解膝过伸问题。

Objective:To investigate the effect of three-dimensional gait analysis training-assisted therapy on knee hyperextension in elderly post-stroke hemiplegic patients.Method:90 cases of elderly post-stroke hemiplegic patients admitted to Wuxi Rehabilitation Hospital from January 2021 to December 2023 were selected as the study subjects,and were equally divided into a control group and a study group by random number table method,with 45 cases in each group.The patients in the control group applied conventional rehabilitation training,while the patients in the research group adopted three-dimensional gait analysis training.The lower limb motor function,balance function,and gait spatio-temporal parameters of the two groups were compared.Result:After the intervention,the scores of the Brief Motor Function Rating Scale(FMA)and Berg Scale(BBS)were higher than those before the intervention in both groups,and the difference was statistically significant(P<0.05).After intervention,the number of knee hyperextension was lower than before intervention in both groups,and the difference was statistically significant(P<0.05).After the intervention,the step frequency,step length,step speed,and swing phase time of the affected side were higher than those before the intervention in both groups,and the difference was statistically significant(P<0.05).After intervention,the walking cycle,affected side support phase time,and double support phase time of the two groups were shorter than those before intervention,and the difference was statistically significant(P<0.05).Conclusion:Three-dimensional gait analysis training assistance therapy applied to elderly post-stroke hemiplegic patients can improve their lower limb motor function and balance function,and effectively alleviate the problem of knee hyperextension.
