Details and patient eligibility

About

This study aims to investigate whether preoperative gait characteristics, measured by wearable sensors, can predict the clinical outcomes of Deep Brain Stimulation (DBS) in patients with dystonia. Participants scheduled for DBS surgery will undergo gait analysis using wearable sensors before the procedure. Clinical assessments, including the Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) and the SF-36 Health Survey, will be conducted preoperatively and postoperatively to evaluate surgical efficacy and quality of life. The study seeks to identify gait biomarkers that correlate with optimal DBS response.
