For years, scientists have studied how the brain controls movement by asking patients to perform structured tasks while connected to multiple sensors in a lab. While these studies have provided important insights, they do not fully capture how the brain functions during everyday activities, be it walking to the kitchen for a snack or strolling through a park. For people living with Parkinson’s disease, this gap between laboratory research and real-world behavior has limited efforts to improve gait symptoms outside of the clinic.
