Effect of Virtual Reality-Based Mindfulness-Based Cognitive Therapy in Patients With Chronic Nonspecific Low Back Pain: Protocol for a Prospective, Multi-Center, Open-Label Randomized Controlled Trial

This is a multi-center, prospective, open-label randomized controlled trial evaluating the efficacy and safety of virtual reality-based mindfulness-based cognitive therapy (VR-MBCT) as an adjunct to usual care in adults with chronic nonspecific low back pain (CNLBP). A total of 214 participants aged 20-70 years with pain duration ≥3 months and average back pain bothersomeness ≥4 (0-10 scale) will be enrolled from three hospitals in China and randomized 1:1 to an 8-week VR-MBCT intervention group or a waitlist usual care control group. The co-primary outcomes are the proportions of patients achieving ≥30% improvement from baseline in Oswestry Disability Index (ODI) and self-rated back pain bothersomeness at week 8. Secondary outcomes include pain intensity (NRS), global improvement, anxiety (GAD-7), depression (PHQ-9), physical activity (IPAQ-SF), sleep quality (SQS), fear-avoidance beliefs (FABQ-PA), pain catastrophizing (PCS), work productivity (WPAI-GH), treatment use, system usability (SUS), and patient satisfaction. Safety will be monitored for VR-related adverse events. Assessments will be performed at baseline (T0), week 4 (T1), week 8 (T2), and week 26 (T3). Data will be analyzed following the intention-to-treat principle using mixed-effects models and per-protocol analyses.

Description détaillée

Chronic nonspecific low back pain (CNLBP) is a leading global cause of disability, yet conventional treatments often focus on structural damage and neglect cognitive, emotional, and behavioral dimensions. Mindfulness-based cognitive therapy (MBCT) is effective for chronic pain but limited by therapist resources and low adherence. Virtual reality (VR) provides an immersive, standardized platform to improve treatment fidelity, engagement, and scalability. This multi-center randomized controlled trial investigates a tailored 8-week VR-MBCT intervention for CNLBP.

The intervention group receives a hybrid VR-MBCT program consisting of 1 weekly in-clinic VR session (approximately 30 minutes) plus at least 3 home-based audio practice sessions (20-30 minutes per session) for 8 weeks. The progressive curriculum includes automatic pilot and awareness, body scan, mindful movement, graded exposure, responding versus reacting, cognitive defusion, self-compassion, relapse prevention, self-care, and real-world transfer training. The control group receives usual medical care only during the 8-week study period and will be offered the same VR-MBCT intervention after completing the 26-week follow-up.

Outcome assessments are conducted at baseline (T0), week 4 (T1), week 8 (T2), and week 26 (T3). Co-primary outcomes are the proportion of participants achieving ≥30% improvement in Oswestry Disability Index (ODI) and back pain bothersomeness (0-10 scale) at week 8. Secondary outcomes include pain intensity (NRS), global improvement, depression (PHQ-9), anxiety (GAD-7), physical activity (IPAQ-SF), sleep quality (SQS), fear-avoidance beliefs (FABQ-PA), pain catastrophizing (PCS), work productivity and activity impairment (WPAI-GH), and use of concomitant treatments. System usability scale (SUS) and patient satisfaction are assessed in the intervention group only. Safety assessments include monitoring and grading of VR-related adverse events such as dizziness, nausea, eye fatigue, headache, and falls at each contact.

Randomization is performed using a computer-generated sequence with 1:1 allocation, stratified by sex and pain duration (<2 years versus ≥2 years). Outcome assessors and statisticians are blinded to group assignment. Data management follows Good Clinical Practice (GCP) with double-entry verification and independent monitoring. This study will provide evidence for VR-MBCT as a scalable, standardized, non-pharmacological adjunctive intervention for CNLBP.

Expérimental: VR-Based Mindfulness Cognitive Therapy Intervention Group
Comportemental: Virtual Reality-Based Mindfulness Cognitive Therapy (VR-MBCT)
Participants in the intervention group will receive an 8-week VR-based telerehabilitation program integrating mindfulness-based cognitive therapy (MBCT), pain neuroscience education (PNE), and graded exposure principles, specifically designed for chronic non-specific low back pain (CNLBP) besides usual clinical care. The program will be delivered through a VR-MR system co-developed by the research team and a technology company in Hangzhou. The system will comprise a PICO Ultra VR-MR headset for immersive mixed-reality experiences and a DM-TG01A motion capture camera for real-time tracking of participant movements and postures. All equipment will be provided to participants at no cost.
Comparateur actif: Waitlist Usual Care Control Group
Autre: Waitlist Usual Care Control Group
The control group will receive standard clinical care (including pharmacological treatment, physical therapy, and home exercise as usual) without any structured VR training for the initial 8-week study period. After completing the 6-month follow-up assessment, control group participants will be offered the same 8-week VR-MBCT program based on their choices.
