Identification of Clinically Relevant Markers of Deep Brain Stimulation Electrode Impedance

Completed · Not applicable

Conditions studied: Parkinson Disease

In brief

The study will look into the changes of Deep Brain Stimulation (DBS) measured impedances in patients of Parkinson disease (PD) as a function of their functional state (lying, sitting and walking) and dopaminergic medication intake (levodopa or dopamine agonists). The goal is to use DBS measured impedance as a surrogate of the functional and medication states of PD patients.
