: The use of standardized screening protocols may inform brain-computer interface (BCI) research procedures to help maximize BCI performance outcomes and provide foundational information for clinical translation. Therefore, in this study we developed and evaluated a new BCI screening protocol incorporating cognitive, sensory, motor and motor imagery tasks. : Following development, BCI screener outcomes were compared to the Amyotrophic Lateral Sclerosis Cognitive Behavioral Screen (ALS-CBS), and ALS Functional Rating Scale (ALS-FRS) for twelve individuals with a neuromotor disorder. : Scores on the cognitive portion of the BCI screener demonstrated limited variability, indicating all participants possessed core BCI-related skills. When compared to the ALS-CBS, the BCI screener was able to modestly discriminate possible cognitive difficulties that are likely to influence BCI performance. In addition, correlations between the motor imagery section of the screener and ALS-CBS and ALS-FRS were non-significant, suggesting the BCI screener may provide information not captured on other assessment tools. Additional differences were found between motor imagery tasks, with greater self-ratings on first-person explicit imagery of familiar tasks compared to unfamiliar/generic BCI tasks. : The BCI screener captures factors likely relevant for BCI, which has value for guiding person-centered BCI assessment across different devices to help inform BCI trials.
使用标准化的筛选方案可以为脑机接口(BCI)研究程序提供信息,帮助最大限度地提高 BCI 的性能结果,并为临床转化提供基础信息。因此,在这项研究中,我们开发并评估了一种新的 BCI 筛选方案,其中包含认知、感觉、运动和运动想象任务。
在开发之后,我们将 BCI 筛选器的结果与肌萎缩性侧索硬化认知行为筛查(ALS-CBS)和肌萎缩性侧索硬化功能评定量表(ALS-FRS)进行了比较,比较对象是 12 名患有神经运动障碍的个体。
BCI 筛选器认知部分的分数变化不大,这表明所有参与者都具备核心的 BCI 相关技能。与 ALS-CBS 相比,BCI 筛选器能够适度区分可能影响 BCI 性能的认知困难。此外,筛选器中运动想象部分与 ALS-CBS 和 ALS-FRS 之间的相关性没有统计学意义,这表明 BCI 筛选器可能提供了其他评估工具无法捕捉到的信息。在运动想象任务之间还发现了其他差异,与不熟悉/通用的 BCI 任务相比,参与者对熟悉任务的第一人称明确想象的自我评分更高。
BCI 筛选器捕捉到了可能与 BCI 相关的因素,这对于指导不同设备的以患者为中心的 BCI 评估具有价值,有助于为 BCI 试验提供信息。
