目的：采用基于商用脑电图（EEG）的脑机接口（BCI），对6例痉挛性四肢瘫痪性脑瘫患者（GMFCS和MACS IV和V）的训练和测试方案进行评估。方法：采用定制化、游戏化的训练模式。在三周的时间里，参与者花了两个阶段探索这个系统，玩了六个阶段的游戏，主要关注左右手臂运动图像的脑电图反馈。结果：参与者在产生两种截然不同的脑电图模式的能力方面表现出可变的不确定结果。参与者的表现受到身体疾病、动机、疲劳和注意力的影响。结论：本案例研究的结果强调了脑机接口作为脑瘫患者辅助技术的起步阶段。现有的商用bci没有根据最终用户的需求进行设计。
Purpose: Using a commercial electroencephalography (EEG)-based brain-computer interface (BCI), the training and testing protocol for six individuals with spastic quadriplegic cerebral palsy (GMFCS and MACS IV and V) was evaluated. Method: A customised, gamified training paradigm was employed. Over three weeks, the participants spent two sessions exploring the system, and up to six sessions playing the game which focussed on EEG feedback of left and right arm motor imagery. Results: The participants showed variable inconclusive results in the ability to produce two distinct EEG patterns. Participant performance was influenced by physical illness, motivation, fatigue and concentration. Conclusions: The results from this case study highlight the infancy of BCIs as a form of assistive technology for people with cerebral palsy. Existing commercial BCIs are not designed according to the needs of end-users.
