This pilot study aims to evaluate the integration of virtual reality (VR) with a psychoeducational program for individuals experiencing chronic pain and central sensitization. Chronic pain significantly hampers daily life, and the condition of central sensitization intensifies this challenge by making the pain more acute. Our research is grounded in the hypothesis that VR, when used to complement conventional psychoeducational methods, can enhance engagement and understanding of pain management strategies, thus potentially improving patient outcomes.

Key objectives and related measured variables include:

Usability and Feasibility: Evaluated through the System Usability Scale (SUS) responses from both participants and healthcare professionals, assessing the ease of use and integration of VR into the psychoeducational program.

Participant Engagement and Program Adherence: Determined by participants' satisfaction with the VR system, using Likert scale questionnaires, and tracked through session attendance and program completion rates.

Impact on Chronic Pain Management and Emotional Well-being: Assessed through changes in the Warwick-Edinburgh Mental Well-being Scale (WEMWBS), and the Hospital Anxiety and Depression Scale (HADS) collected at baseline, post-intervention, and 4-8 weeks follow-up Self-management of Chronic Pain: Monitored through the Central Sensitization Inventory (CSI) and changes in patient functionality and mobility using the EuroQol-5D-5L scale, measured at baseline, post-intervention, and 4-8 weeks follow-up.

Healthcare Professionals' Perceptions: Investigated using SUS scores and qualitative feedback on the applicability and benefits of VR in clinical practice for chronic pain management.

Participants will complete eight 90-minute sessions, engaging with VR to supplement the program's content. This approach aims to provide immersive experiences that deepen the understanding and management of chronic pain. Participant feedback on the VR experience, alongside observed changes in pain management and overall well-being, will be critically examined.

By targeting individuals suffering from chronic pain, this research aims to offer healthcare professionals an innovative tool for enhancing pain management strategies. Integrating VR into psychoeducational content, the study seeks to promote more engaging and effective learning experiences, potentially leading to improved outcomes in chronic pain management.

The REDOCVR study is an innovative initiative to evaluate the adjunctive use of Virtual Reality (VR) within a psychoeducational framework for managing chronic pain and central sensitization. This initiative aims to harness the immersive potential of VR to enhance traditional psychoeducational strategies, thereby providing a more engaging and impactful patient experience.
