Monitoring Gait at Home with Radio Waves in Parkinson's Disease: a Marker of Severity, Progression, and Medication Response

Summary

Demonstrates continuous longitudinal gait monitoring of Parkinson's disease patients at home using radio wave sensing — without any wearable device. The system extracts gait speed, step length, and cadence from RF reflections as subjects move through their home environment. Tracking is entirely passive and unobtrusive.
