Scoring upper-extremity motor function from EEG with artificial neural networks: a preliminary study
Bibliographic record
Abstract
OBJECTIVE: Motor function of chronic stroke survivors is generally accessed using clinical motor assessments. These motor assessments are partially subjective and require prior training for the examiners. Additionally, those motor function assessments require the health professionals to be present in person. The method proposed in this paper has the potential to radically change the way motor function is assessed. APPROACH: This work investigates the feasibility of automatically scoring upper-extremity motor function from EEG using artificial neural networks. Twelve healthy participants and fourteen participants with chronic stroke participated in this study. EEG data were recorded while the participants were clicking a button. Convolutional neural network models were trained based on the participants' Fugl Meyer motor assessment score. MAIN RESULTS: ) participant testing. SIGNIFICANCE: This evidence suggests the proposed method is feasible to be used as a stable and objective measurement for motor function assessment.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
