Movement State-dependent Adaptive DBS for PD

This is a single-center clinical study aiming to improve gait functions in patients with Parkinson's Disease (PD) by using adaptive neurostimulation to the pallidum. The investigators will use a bidirectional deep brain stimulation device with sensing and stimulation capabilities to 1) identify neural biomarkers to detect the onset of walking by recording neural activities from the motor cortical areas and the globus pallidus, 2) understand the impacts of changes in DBS parameters on gait kinematics and optimize setting parameters for enhancing walking performance, 3) develop a movement state-dependent adaptive deep brain stimulation (DBS) paradigm to automatically switch stimulation settings according to different movement states (i.e., walking vs non-walking). The proposed therapy will deliver personalized neurostimulation based on individual physiological biomarkers to enhance gait function in patients with PD. 6 patients with idiopathic Parkinson's disease who have already been implanted with the Medtronic Summit RC+S device will be enrolled in this study.
