abstract：BACKGROUND:Up to 60% of Parkinson's disease (PD) patients suffer from low back pain (LBP) during the course of their disease. How LBP affects daily functional status and how to manage this aspect of PD has not been adequately explored. METHODS:We examined 16 patients undergoing bilateral subthalamic nucleus deep brain...
