This is an optional study that is conducted in parallel to CAPTURE ALS (NCT05204017). In this exploratory, prospective, longitudinal study, CAPTURE ALS participants undergo remote physiological data collection using smartwatch technology. Participants will wear a specialized smartwatch (Health Gauge AI-Based Wearable Device ) for the duration of the study. ALS patients will be followed for 12 months, healthy controls will be followed for 8 months. Digital questionnaires will monitor participant-related outcomes bi-monthly. Gait assessments will be performed by ambulatory patients and healthy controls in clinic during CAPTURE ALS study visits to measure changes in walking activity.
This observational study will use new smartwatch technology to continuously and remotely monitor the health of ALS patients and healthy controls over time. This information will be used to develop digital biomarkers for ALS.
