NCT02012647
The purpose of this study is to examine the brain changes in people with Parkinson's Disease (PD) after they get deep brain stimulation (DBS) surgery, compared with people who do not have Parkinson's Disease. Treatment of Parkinson's disease is often difficult and challenging. Deep brain stimulation is an established surgical treatment that is effective for the treatment of PD, but the details of why it helps are not known. In order to achieve maximum benefits from this treatment, it is important to understand how it changes the brain. Specifically, the investigators will study electrophysiology, which is the study of how the brain conducts electrical messages to the rest of the body. To do this, the investigators will use transcranial magnetic stimulation (TMS), which is a painless and non-invasive procedure. They will also conduct motor physiology experiments of the upper and lower limbs to collect data about skeletal muscle movement. The data from this study will help explain whether the electrical changes in the brain have any relation to the physical benefits patients with Parkinson's Disease sometimes receive from DBS surgery.

Spinal cord stimulation (SCS) has been suggested by several research for treating PD gait disturbance. However, the side effects induced by body position change cannot fully addressed by conventional SCS. Medtronic sensor-driven position-adaptive SCS are capable to monitor the position change and change the parameters accordingly, so as to reduce the position change related side effects. Nevertheless, neither the efficacy nor safety of this technique in the treatment of gait disturbance in PD is ever investigated. Therefore, the investigators will conduct a randomized clinical trial to investigate the clinical efficacy and safety of sensor-driven position-adaptive SCS in the treatment of gait disturbance in PD. This study will contribute to find out the safety and efficacy of sensor-driven position-adaptive SCS in the treatment of PD gait disorder, improve patients' quality of life, and reduce the burden on family and society.
