Bayesian Optimization of DBS for Gait

Who can join

Ages 18 and older · All sexes

Inclusion Criteria:

* Diagnosis of Parkinson's Disease
* DBS in STN or GP (bilateral or unilateral)
* At least 3 months after lead implantation

Exclusion Criteria:

* Inability to walk in the off-med, off-stimulation condition (even with safety harness)
* Gait impaired significantly by a condition other than PD, as determined by the PI
* Breaks or shorts in active contacts
* IPG battery nearing end of life (in patients with primary-cell IPGs)
* Females who are nursing or pregnant
* Diminished capacity to consent (concluded via UBACC)

About the study

This project aims to establish the feasibility of Bayesian optimization for tuning deep brain stimulation (DBS) to treat gait symptoms in Parkinson's disease (PD) patients. Our primary question is: Can Bayesian optimization of DBS achieve reproducible results within a feasible number of gait measurements? PD patients will be enrolled who have DBS of the subthalamic nucleus (STN) or globus pallidus (GP) in whom at least 3 months have passed since activation of their neurostimulators, for stabilization of clinical stimulator settings. We will apply Bayesian optimization to derive DBS settings which maximally lengthen step length relative to the OFF DBS state.
