摘要

We developed a method to quantify hand postural tremor amplitude and frequency from standard videos without external calibration. Using iris-based scaling and deep-learning models for 3D pose estimation and hand tracking, the automatic approach demonstrated excellent agreement with manual measures. Clinical validation in persons with Parkinson’s disease demonstrated sensitivity to treatment effects and strong correlation with clinician-provided scores. The proposed method, available as part of VisionMD, enables objective, scalable assessment of postural tremor from standard videos.
