Effect of Increasing Physical Activity on Cognitive Function in Individuals With Mild Cognitive Impairment: A Knowledge Translation to Practice Pilot Project
Bibliographic record
Abstract
The purpose of the current pilot study was to determine if 12 weeks of increased physical activity improved cognitive function in individuals with mild cognitive impairment (MCI). Participants used commercial wearable technology to objectively measure daily steps. Participants wore an activity tracker for approximately 12 hours per day and received telephone support every 2 weeks. The Montreal Cognitive Assessment (MoCA) was used to measure pre/posttest cognitive function. Increased step count was positively correlated with improvement in cognitive function with a moderate effect size (Pearson's r = 0.55; p = 0.04); 5,396 steps per day was the decision boundary for MoCA score improvement. Increased physical activity over 12 weeks improved cognitive function in individuals with MCI. It is feasible for individuals with MCI to wear an activity tracker on a daily basis.

How this classification was reachedexpand
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.
