Construction and Validation of the Hybrid Brain-Computer Interface-Functional Electrical Stimulation Motor Rehabilitation System
摘要
Abstract
Objective To provide a novel neurorehabilitation approach for hand motor function recovery in stroke patients,a hybrid brain-computer interface(BCI)-functional electrical stimulation(FES)motor rehabilitation system was developed by integrating motor imagery(MI)and peripheral steady-state visual evoked potential(SSVEP). Methods Healthy subjects who met the inclusion criteria were selected to construct a hybrid BCI-FES motor rehabilitation system.During the experiment,hand-grasping videos were displayed in the central visual field to guide subjects in performing hand MI,while high-frequency visual flickers were presented in the peripheral visual field to elicit SSVEP.The filter bank common spatial pattern and extended task-related component analysis algorithms were employed to detect MI and SSVEP signals,respectively.A fusion strategy based on classification probability and correlation coefficient was used to determine the final classification result,which subsequently triggered FES to induce hand movement. Results A total of 11 healthy subjects were enrolled in the study,including 5 females and 6 males,with a mean age of(24.3±1.6)years.Online experimental results from healthy subjects demonstrated that the average classification accuracy of the BCI-FES motor rehabilitation system reached 98.48％,significantly outperforming traditional single-paradigm approaches. Conclusions This study developed a BCI-FES motor rehabilitation system integrating MI and SSVEP,validated its feasibility,and provided an innovative solution for rehabilitation training in patients with motor dysfunction.关键词
