- Dual foundation models for accelerometry predict future health2026 · medRxiv preprint
This medRxiv study encoded one week of UK Biobank wrist accelerometry from 97,696 people with two frozen self-supervised models and trained one survival model for 390 health outcomes. In 5,253 held-out participants mean concordance was 0.688, and one shared component explained 76% of predicted risk variance. Movement data also flagged early signs of neurodegenerative disease, strongest for Parkinson's (five-year AUROC 0.90).
