Quick Navigation

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

The purpose of this study is to evaluate the feasibility and preliminary efficacy of deep brain stimulation of the subgenual cingulate cortex for the treatment of chronic medically-refractory low back pain using a randomized double-blind crossover design.
