Virtual Reality-Based Rehabilitation in Chronic Low Back Pain: Effects on Muscle Architecture, Balance, and Satisfaction (VR-LBPREHAB)

Chronic low back pain is a common musculoskeletal disorder that causes pain, disability, and reduced quality of life. It is often related to changes in trunk muscle function, thoracolumbar fascia morphology, and impaired balance control. Although conventional motor control exercises are effective, patient motivation and adherence can be limited. Virtual reality (VR)-based rehabilitation offers interactive and engaging environments that may improve compliance and provide additional therapeutic benefits. This study is a randomized controlled trial designed to investigate the effects of VR-based rehabilitation compared with conventional motor control exercises in individuals with chronic low back pain. A total of 40-50 participants aged 18-65 will be recruited and randomly assigned to one of two groups: (1) VR-based rehabilitation or (2) conventional exercise therapy. Both programs will last 8 weeks, delivered three times per week for 40 minutes per session. The primary outcomes include muscle architecture assessed by ultrasound imaging, thoracolumbar fascia morphology, and postural balance control measured by force platform tests. Secondary outcomes include pain intensity, disability, fear-avoidance beliefs, quality of life, and patient satisfaction. The findings of this study are expected to provide new insights into the role of VR in rehabilitation and contribute to evidence-based strategies for managing chronic low back pain. By exploring the effects on both physical and patient-reported outcomes, the study may highlight innovative approaches to improve adherence, reduce pain, and enhance daily function in affected individuals.
