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

To enable the elderly and non-ambulatory gait-impaired patients, the repetitive practice of this task, a novel gait training robot(GTR) was designed followed the end-effector principle, and an active partial body weight support(PBWS) system was introduced to facilitate successful gait training. For successful establishment of a walking gait on the GTR with PBWS, the motion laws of the GTR were planned to enable the phase distribution relationships of the cycle step, and the center of gravity(COG) trajectory of the human body during gait training on the GTR was measured. A coordinated control strategy was proposed based on the impedance control principle. A robotic prototype was developed as a platform for evaluating the design concepts and control strategies. Preliminary gait training with a healthy subject was implemented by the robotic-assisted gait training system and the experimental results are encouraging.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
