Pilot study introduces a novel framework for risk screening in early Parkinson's disease, facilitating automated mobility assessment.

To develop a low-cost, automated framework using uncalibrated cameras for early screening of Parkinson’s disease risk.
Introduced a Physics–Data Hybrid framework for processing data from consumer-grade CMOS cameras.
Utilized a noise-adaptive fusion strategy to extract spatiotemporal gait parameters without manual calibration.
Evaluated the system's performance using a pilot study with 10 subjects to assess screening accuracy.
Achieved 98% screening accuracy using extracted metric features.
Overall classification accuracy reached 87.32% for Parkinson’s disease risk assessment.
Demonstrated the ability to capture subtle motor fluctuations better than conventional systems.

Qiu et al. (2026) studied this question.
