简要总结
Current evidence and clinical applications of robotic gait training devices for motor function recovery post-stroke are increasingly available. Although existing research demonstrates that robotic gait training can improve patients' gait and balance, there remains a lack of in-depth investigation into its specific mechanisms of action concerning central nervous system (CNS) reorganization - notably, changes in activity within the motor cortex and associated neural networks. The intrinsic changes within the CNS have received insufficient attention, limiting a comprehensive and profound understanding of the rehabilitation outcomes. Therefore, this study aims to elucidate the potential mechanisms underlying robotic gait training-induced neuroplasticity by integrating functional near-infrared spectroscopy (fNIRS) technology with multi-dimensional lower limb motor function assessment tools (such as FAC, BBS, AMEDA, 10MWT, 6MWT, TUGT). It will systematically investigate the effects of robotic gait training on both the central nervous system and lower limb motor function in stroke patients. Furthermore, the study will compare the differences in functional recovery efficacy between robotic gait training and conventional rehabilitation therapies.
详细描述
In this study, participants will be randomly allocated into two groups: the Welwalk training group and the conventional rehabilitation therapy group.
Welwalk Training Group: Each session will consist of 30 minutes of Welwalk robot-assisted training, followed by 15 minutes of gait training and 15 minutes of supplementary exercises.Control Group (Conventional Rehabilitation Therapy): Each session will consist of 45 minutes of gait training and 15 minutes of supplementary exercises.The intervention period will span 3 weeks, with sessions administered six times per week. Each session will last 1 hour.
Clinical assessments will be conducted by certified healthcare professionals at four time points: at baseline (prior to the commencement of formal training), and after the 1st week, 2nd week, and 3rd week of treatment.

结局指标
主要结局
The Functional Ambulation Categories (FAC)
时间窗: Before intervention (Week 0); After the First week of intervention (Week 1); After the Second week of intervention (Week 2); After the Third week of intervention (Week 3);
FAC is a functional walking test that evaluates ambulation ability. This 6-point scale assesses ambulation status by determining how much human support the patient requires when walking, regardless of whether or not they use a personal assistive device.The FAC uses a six-point scale from 0 to 5, where a higher score indicates better performance.
