Algorithm Guided DBS Programming in Parkinson's Patients

Patients of Parkinson's disease undergoing bilateral subthalamic nucleus stimulation (STN), we have already been adequately programmed and have achieved good outcome, will undergo an exploratory study to evaluate the effectiveness of algorithm based programming (Phase 1). Subsequently, patients undergoing STN DBS will be randomly allocated to algorithm based programming/ standard of care programming and after adequate stabilisation evaluated for motor improvement. They will be switched over to the alternative technique of programming and evaluated again after a similar period. Data regarding the time consumed, effectivity and several secondary endpoints will be evaluated.
