Official title
Adaptive Cortical and Subcortical Brain Stimulation to Improve Motor Behaviors and Gait in Parkinson's Disease
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a single-center phase I 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) decode the physiological signatures of gait and gait adaptation by recording neural activities from the motor cortical areas and the globus pallidus during natural walking and a gait adaptation task, and 2) develop an adaptive deep brain stimulation (DBS) paradigm to selectively stimulate the pallidum during different phases of the gait cycle and measure improvements in gait parameters. This is the first exploration of network dynamics of gait in PD using chronically implanted cortical and subcortical electrodes. In addition to providing insights into a fundamental process, the proposed therapy will deliver personalized neurostimulation based on individual physiological biomarkers to enhance locomotor skills in patients with PD. Ten patients with idiopathic Parkinson's disease undergoing evaluation for DBS implantation will be enrolled in this single treatment arm study.
