    Digital health technology measurements show potential as objective biomarkers in Parkinson's disease but lack sensitivity across early disease stages.

  • 2

    The study evaluated various digital health technology measures in tremor, bradykinesia, and axial symptom domains to differentiate early stage PD from healthy controls.

  • 3

    Distinct categories of functional measures were identified, with some effectively differentiating PD patients from healthy controls but limited in sensitivity to early progression.

  • 4

    Models trained on disease-stage specific feature sets demonstrated improved performance for progression detection compared to combined features.

  • 5

    The findings highlight the importance of aligning digital biomarker design with disease stage and clinical objectives for better diagnosis and monitoring.
