Overview

• Wearable sensors tracked over 100 physiological metrics and proved better than clinical tests at gauging Parkinson's progression.
• The sensors tracked metrics like toe movement during walking and stride length to assess disease progression.
• Researchers are optimistic this technology could also track other illnesses like Alzheimer's.
• The findings provide a new tool to evaluate whether Parkinson's drugs and therapies are effective.
• Experts say the sensors' effectiveness shows promise for digital tracking of neurodegenerative diseases.
