Gait Foundation Model Predicts Multi-System Biomarkers
Researchers led by Adam Gabet et al. (submitted 26 March 2026) develop a gait foundation model for 3D skeletal motion trained on 3,414 deeply phenotyped adults recorded via a depth camera across five motor tasks. Learned embeddings outperformed engineered features, predicting age (r = 0.69), BMI (r = 0.90), and visceral adipose tissue area (r = 0.82), and significantly predicted 1,980 of 3,210 phenotypic targets. Findings motivate translation to consumer-grade video and integration of gait as a scalable, passive vital sign.
