Understanding Tiredness During Daily Activities in Spinal Muscular Atrophy

This study is designed to better understand fatigue and how people with spinal muscular atrophy experience tiredness during everyday activities, especially those being treated with nusinersen. While this medication has helped extend survival and improve movement, people still report struggling with tiredness and the ability to keep doing physical activities. This research aims to measure and understand that tiredness in a way that reflects real life.

Even though this medication has improved survival and motor function for people with spinal muscular atrophy, fatigue remains a significant problem in daily life. Researchers don't yet have a good way to measure how tiredness affects people's ability to do repetitive physical tasks, and they want to understand whether the medication's effectiveness changes over time between treatments.
