NCT03548506

Brief Summary

Twenty patients with idiopathic Parkinson's disease (PD) will be included into this single center randomized controlled double-blind clinical trial (RCT) in a cross-over design. The treatment consists of two different stimulation settings using (i) conventional omnidirectional stimulation of the subthalamic nucleus \[STN\_O\] as active comparator and (ii) directional steering of STN stimulation via a segmented electrode contact \[STN\_D\].
