研究目的: |
验证DN-DBS联合标准化康复治疗慢性期卒中偏瘫的安全性与初步有效性;估计主要结局效应量与方差;探索与疗效相关的临床/影像/电生理候选影响因素,为后续多中心确证性研究提供依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
To evaluate safety and preliminary efficacy of DN-DBS combined with standardized rehabilitation in chronic post-stroke hemiparesis; to estimate effect size and variance for the primary outcome; and to explore candidate clinical, imaging, and electrophysiological predictors to inform future multicenter confirmatory trials. |

|
药物成份或治疗方案详述: |
所有受试者植入双侧小脑齿状核DBS电极与脉冲发生器(IPG)。术后约4周首次开机程控,默认先启用病灶对侧单侧刺激,采用“低起点、小步递增、以疗效与耐受为导向”的个体化参数优化(幅度/频率/脉宽)。完成开机后3个月评估且耐受良好后,按方案切换为双侧刺激,持续至开机后6个月终末访视。全程提供统一标准化康复(任务导向上肢训练、PT/OT等),并记录康复剂量与依从性。 |
||||||||||||||||||||||
|
Description for medicine or protocol of treatment in detail: |
All participants undergo implantation of bilateral dentate nucleus DBS leads and an implantable pulse generator (IPG). Initial programming is performed about 4 weeks postoperatively. Contralesional unilateral stimulation is applied first, with individualized parameter optimization (amplitude/frequency/pulse width) using a low-start, slow-titration, efficacy-and-tolerability–guided approach. After the 3-month post-activation assessment and confirmed tolerability, stimulation is switched to bilateral and continued until the 6-month post-activation final visit. Standardized rehabilitation (task-oriented upper-limb training, PT/OT) is delivered throughout, with rehabilitation dose and adherence recorded. |
