Enrollment | 255 |
Recruitment Details | Patient recruitment begun in May 2002 and the discontinuation of randomization to the BMT arm was approved in August 2005 and participating sites received their IRB approval of this change through October 2005. A total of 255 patients were randomized to either BMT or DBS from 7 VA medical centers and 6 affiliated university sites. |
Pre-assignment Details | An additional 23 patients were screened after signing the informed consent form but not randomized. 11 of them weren't willing to participate in the follow-up visits after intervention, 7 of them had neuropsychological dysfunction, 2 of them were not responsive to levodopa, and 3 had medical contraindication to surgery and/or DBS stimulation. |

Bilateral Deep Brain Stimulation Bilateral Deep Brain Stimulation : The DBS site (STN or GPi) will be assigned on a random basis at the time the patient enters the surgical phase of the trial. |
Best Medical Therapy best medical therapy : Participants will initially be randomized to DBS or to 6 months of "best medical therapy." BMT participants will then proceed into the surgical phase of the trial. Effective 08/05/05, randomization to the BMT arm has been discontinued since the study has sufficient information to compare the outcomes of DBS and BMT patients at 6 months. |
