This study aimed to elucidate the changes of cortical blood flow in seven elderly patients with post-stroke hemiplegia before and after body weight support treadmill training by semi-quantitative analysis of regional cerebral blood flow assessed by single photon emission computed tomography. Body weight support treadmill training for 6 months was effective in improving cerebral blood flow and promoting the walking speed and balance recovery in elderly patients with post-stroke hemiplegia.展开更多

目的:针对脑卒中后偏瘫患者早期开展减重步行训练(partial body weight support treadmill training,PBWSTT)存在的膝、踝关节控制不良,采用靶向性训练,观察其对下肢运动功能、步行能力和ADL的影响。方法:选择病程在3个月内、偏瘫肢体Br...目的:针对脑卒中后偏瘫患者早期开展减重步行训练(partial body weight support treadmill training,PBWSTT)存在的膝、踝关节控制不良,采用靶向性训练,观察其对下肢运动功能、步行能力和ADL的影响。方法:选择病程在3个月内、偏瘫肢体Brunnstrom分期≥Ⅱ期的稳定性卒中患者28例作为试验组,均接受靶向性训练和PBWSTT训练。结果:两组患者经不同康复治疗后,治疗前后均有明显的差异。试验组FAC由治疗前0.37±0.14提高到治疗后3.9±1.2、FMA由治疗前21.8±6.3提高到治疗后42.5±7.6、FIM由治疗前33.8±3.3提高到治疗后86.8±9.6;对照组FAC由治疗前0.38±0.28提高到治疗后2.6±1.1、FMA由治疗前19.1±5.6提高到治疗后32.6±5.2、FIM由治疗前32.3±4.8提高到治疗后73.8±7.8。试验组FAC、FMA积分及FIM评分的改善情况明显优于对照组(P<0.05)。治疗后试验组患者的独立步行能力改善也明显优于对照组(P<0.05)。结论:减重步行结合靶向性膝踝控制训练有利于提高下肢运动功能、步行能力及ADL。展开更多
