Virtual Pain Education for Spinal Cord Stimulation Patients

Overview

Chronic pain is a leading cause of disability in the United States. When standard treatments fail, many patients develop treatment resistant pain and undergo Spinal Cord Stimulation (SCS) therapy. SCS uses an implanted device to send mild electrical currents to the spine to block pain signals before they reach the brain. However, long-term success is often limited by how a patient's nervous system and brain process chronic pain, as well as psychological factors like anxiety and excessive worrying about pain, also known as catastrophizing. To improve outcomes, this study combines SCS therapy with Pain Neuroscience Education (PNE). PNE is an educational approach that teaches patients how the brain and nervous system handle pain signals, reframing pain as a process that can be changed rather than just ongoing tissue damage. The goal of this pilot trial is to test the feasibility of using virtual, remote PNE sessions to help patients reduce pain catastrophizing and anxiety, while building overall psychological resilience. Additionally, the study explores an innovative, objective way to monitor pain levels by analyzing short voice recordings. Researchers want to see if specific vocal features change when a person's pain is well-controlled versus when it is uncontrolled. Participants enrolled in this study will receive either 1) standard spinal cord stimulation or 2) spinal cord stimulation plus the intervention--a virtual, multi-session PNE delivered remotely over a secure telehealth platform. Throughout the study, participants will complete standard clinical surveys to measure their physical function, anxiety, pain catastrophizing, and emotional resilience using standardized tools. Participants will also provide short voice recordings, such as holding a sustained "/ah/" vowel sound, during their virtual assessments. This allows researchers to safely evaluate the direct relationship between subtle voice patterns and reported clinical pain levels.

(Methodology and Scientific Framework Narrative) This study is structured as a hybrid effectiveness-implementation pilot study designed to systematically evaluate a virtual delivery model for integrating a behavioral pain intervention into neuromodulation care. The protocol operationalizes core Translational Science Principles within a cross-disciplinary team science framework to optimize clinical workflows and enhance patient-centered outcomes for individuals suffering from treatment-resistant pain. The scientific methodology focuses on evaluating the clinical feasibility and implementation metrics of a synchronized, multi-part telehealth curriculum. By utilizing a secure virtual platform, the study examines remote tracking consistency and patient accessibility, determining how a virtual behavioral protocol can be integrated into active interventional pain clinic workflows without disrupting standard medical device management. Methodologically, the intervention targets specific cognitive-behavioral mediators (factors) that traditionally limit the long-term efficacy of spinal cord stimulators. The analysis will measure the feasibility of the virtual PNE delivery model to successfully impact key patient-reported outcomes. Specifically, the study tracks changes in maladaptive cognitive patterns-primarily pain catastrophizing and pain-related anxiety-and evaluates the concurrent promotion of psychological resilience factors. The ultimate objective of this trial is to determine if adding the virtual PNE intervention successfully helps patients improve across these clinical and behavioral scales compared to receiving standard spinal cord stimulation care alone. Simultaneously, this protocol tests an objective pain assessment methodology as an exploratory study variable. Utilizing brief, non-invasive vocal recordings captured at two points during the pilot study during remote telehealth assessments, the study performs acoustic feature extractions on sustained phonations of the /ah/ vowel sound. These objective acoustic metrics are quantitatively modeled across two distinct clinical states: periods of controlled pain and periods of uncontrolled pain. This exploratory analysis evaluates the correlation between objective vocal biomarkers and the standardized clinical scales measuring pain catastrophizing, anxiety, depression, and resilience. The ultimate objective of this exploratory variable is to determine if specific acoustic features can serve as a reliable, non-invasive digital biomarker for tracking longitudinal pain severity and treatment response in remote settings.
