450 FSHD patients join Long-Term study to unlock better treatments
NCT ID NCT04635891
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 450 people with FSHD for at least 3 years to measure how the disease affects walking, arm use, breathing, and other daily activities. The goal is to improve patient care and help researchers design better clinical trials by understanding what changes in movement truly matter to patients. No new treatments are tested—this is an observational study.
