Think BIG: Brain-Computer Interface Goals for Children with Quadriplegic Cerebral Palsy
Bibliographic record
Abstract
There is a pressing need for alternative access technologies that enable children with severe physical disabilities, as current options often require some degree of controlled movement to be used efficiently. Brain-computer interfaces (BCIs) hold significant potential for improving the lives of children with severe physical disabilities, however research must prioritize user-centered approaches and real-world applications to maximize benefits. This paper examines the integration of home-based BCIs for children with quadriplegic cerebral palsy through user-centered design, focusing on the feasibility, usability, and impact on personal goals and activities of daily living. Seven children aged 6–15 years with quadriplegic cerebral palsy and their families participated in this pilot study, using personalized BCI packages and home-based virtual sessions to help them achieve individualized goals in self-care, productivity, and leisure. We utilized a collaborative goal-setting approach and assessed satisfaction and performance changes using the Canadian Occupational Performance Measure (COPM) and the BCI-adapted Quebec User Evaluation of Satisfaction with Assistive Technology (e-QUEST2.0). Significant improvements in performance and satisfaction were observed in the COPM scores, while parents were most satisfied with professional services and least satisfied with the adjustability of the BCI system, as per the eQuest2.0 questionnaire. Despite no significant improvement in BCI consistency across nine sessions, the intervention positively impacted participants' perceived performance and satisfaction in goal-oriented activities. Future research should focus on enhancing BCI design, comfort, and effectiveness while considering user priorities and feedback for personalized goal achievement.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
