ObjectivesLow back pain is the leading cause of years lived with disability with a large impact on quality of life and resistance to a broad array of current treatments. This study aimed to investigate the effect of a novel self-administered behavioral therapy-based virtual reality (VR) application on the quality of life of patients with nonspecific chronic low back pain (CLBP).MethodsA pilot randomized controlled trial was conducted in adults with nonspecific CLBP with moderate to severe pain, waiting for treatment in a teaching hospital-based pain clinic. The intervention group used a self-administered behavioral therapy-based VR application for at least 10 minutes daily for 4 weeks. The control group received standard care. The primary outcome was quality of life at 4 weeks measured by the short form-12 physical and mental scores. Secondary outcomes were daily worst and least pain, pain coping strategies, activities of daily living, positive health, anxiety, and depression. Discontinuation of therapy and adverse events were analyzed as well.ResultsForty-one patients were included. One patient withdrew due to personal reasons. No significant treatment effect was found for the short form-12 physical score (mean difference: 2.6 points; 95% CI: -5.60 to 0.48) and mental score (-1.75; -6.04 to 2.53) at 4 weeks. There was a significant treatment effect for daily "worst pain score" ( F [1, 91.425] = 33.3, P < 0.001) and "least pain score" ( F [1, 30.069] = 11.5, P = 0.002). Three patients reported mild and temporary dizziness.DiscussionFour weeks of self-administered VR for CLBP does not improve quality of life, however, it may positively affect daily pain experience.Copyright © 2023 The Author(s).
