这项研究引入了一种新的多变量控制系统,用于帕金森病 (PD) 中的深脑刺激 (DBS). 它有效地控制和β活性,同时防止副作用和节省电力.
科学领域:
- 神经科学是一个神经科学.
- 生物医学工程 生物医学工程
- 控制系统 控制系统
背景情况:
- 目前用于帕金森病 (PD) 的闭环深脑刺激 (DBS) 通常控制单个生物标志物,导致不相关症状或不同生物标志物-症状关系的亚最佳调节.
- 刺激诱导的副作用的控制在现有的DBS方法中往往没有得到解决.
研究的目的:
- 呈现一种多变量控制架构,用于选择性地抑制PD中的震或亚thalamic核β频段振荡.
- 调节DBS脉冲振幅和持续时间以保持振幅低于值,避免远端轴突的刺激和相关的副作用.
- 调查PD电机网络的计算模型,以模拟拟拟议的控制架构.
主要方法:
- 开发了一个多变量控制架构,调节DBS脉冲振幅和持续时间.
- 根据检测到的肌肉电肌图 (EMG) 活动,监督控制者选择震或β活动控制.
- 二级控制器限制了脉冲振幅和调节脉冲持续时间,以准直径较小的轴突,防止副作用.
主要成果:
- 该系统实现了对静止震动和β活动的良好控制,与开放循环刺激相比,功耗降低.
- 监督控制器防止了单个生物标志物控制器遇到的过度或不足刺激问题.
- 当DBS振幅受到限制时,二级控制器通过调整脉冲持续时间来维持刺激效率,证明了双参数控制的好处.
结论:
- 非线性多变量控制可针对性地抑制PD患者的运动症状.
- 双参数控制可自动调节DBS治疗剂量,防止过度刺激和提高功率效率.
