- The study evaluates previously published models for detecting prodromal Parkinson's disease using wearable movement-tracking data.
- Models trained on UK Biobank data were applied to German and British cohorts with isolated or idiopathic REM sleep behavior disorder and healthy controls.
- The British cohort showed similar activity patterns to UK Biobank but weaker statistical differences and reduced model performance.
- The German cohort exhibited no significant group differences and lower performance, indicating potential issues with model generalizability.
- Models may capture early clinical disease rather than universal prodromal markers, highlighting the need for prospective validation in well-characterized cohorts before clinical translation.
