Multiple Objective Particle Swarm Optimization Postural Instability Gait Disorder

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Sixty patients will be enrolled in this study who are treated for Parkinson's disease (PD) with bilateral deep brain stimulation of subthalamic nucleus (STN) or globus pallidus (GP), who have a pre- operative 7 Tesla MRI including diffusion tensor imaging for tractography and a postoperative head CT for electrode localization, and in whom at least 3 months have passed since activation of their neurostimulators, for stabilization of clinical stimulator settings. Using their MRI and CT, the investigators will construct patient-specific models of electrical current spread to neuroanatomical tar- gets surrounding the electrode. Then applying nonlinear (particle swarm) optimization, patient- specific stimulator settings will be designed to maximally or minimally activate specific path- ways. In STN DBS: pedunculopallidal vs. pallidopeduncular pathways. In GP DBS: pallidopeduncular pathways at its origin in GP pars interna (GPi) vs. inhibitory afferents to GPi (from GP pars externa GPe). All stimulation falls within the the FDA-approved range for DBS for PD.
