Wearable device tracks ALS progression in real life

This study is for people with ALS, a disease that weakens muscles over time. Researchers want to see if a small wearable sensor called Actimyo can measure walking and arm movements during daily life. About 20 participants will wear the sensor for one month after each clinic visit, every three months for a year. The goal is to learn how the disease changes movement patterns, which could help improve future care.
