Abstract

We assessed the efficacy of chronic stimulation of the subthalamic nucleus (STN-DBS) in 20 patients with Parkinson's disease (PD) by means of clinical assessments and patient diaries 12 months after surgery. STN-DBS reduced the UPDRS part III off-medication score by 33%, and successively improved complete daily on-time without dyskinesia at 12 months significantly. In conclusion, our study demonstrates the efficacy of chronic STN-DBS on motor features in a selected population of advanced PD patients. In addition to clinical assessments, patients' diaries serve as an essential tool to evaluate the functional motor status after STN-DBS.
