Can a simple walk test predict brain surgery success?

This study looks at whether walking patterns measured by wearable sensors can predict how well deep brain stimulation (DBS) will work for people with dystonia, a movement disorder. About 50 adults scheduled for DBS surgery will wear sensors before the procedure. Researchers will compare their walking data with standard symptom scores and quality-of-life surveys taken before and after surgery to find clues that point to the best outcomes.
