Virtual Reality-Based Posture Correction Program on Low Back Pain (VR-LBP)
Effect of Virtual Reality-Based Posture Correction Program on Low Back Pain and Dynamic Balance in Desk Workers
調査の概要
詳細な説明
Low back pain (LBP) is one of the most common musculoskeletal disorders among desk workers and is strongly associated with prolonged sitting, poor posture, and reduced physical activity. Extended periods of desk work contribute to biomechanical and neuromuscular changes, including decreased lumbar lordosis, reduced spinal mobility, muscle tightness, impaired trunk muscle activation, and altered postural control. These changes may lead to chronic nonspecific low back pain, functional limitations, and deficits in dynamic balance.
Postural deviations such as forward head posture, rounded shoulders, thoracic kyphosis, and pelvic misalignment are frequently observed in sedentary workers. These alterations affect spinal alignment and may impair proprioceptive input, resulting in decreased balance performance and inefficient neuromuscular control. Impaired balance and reduced sensorimotor awareness have been reported in individuals with chronic low back pain, increasing the risk of functional disability and musculoskeletal dysfunction.
Virtual reality (VR)-based rehabilitation has emerged as an innovative approach for improving postural control and reducing pain. VR systems provide real-time visual feedback and interactive task-oriented exercises that promote active participation and enhance sensorimotor retraining. Through immersive environments, VR interventions may improve trunk muscle activation, proprioceptive awareness, motor coordination, and postural stability while increasing motivation and adherence to exercise programs.
Dynamic posture correction exercises performed within a VR environment may provide additional benefits by integrating physical, cognitive, and sensory stimulation. Previous studies have demonstrated that VR-based interventions can reduce pain intensity, improve functional performance, enhance balance control, and decrease fear-avoidance behaviors associated with chronic pain conditions.
Therefore, this study aims to investigate the effect of a virtual reality-based posture correction program on low back pain intensity and dynamic balance in desk workers. The findings may provide evidence regarding the effectiveness of VR-based posture correction as a rehabilitation strategy for addressing musculoskeletal and balance impairments associated with prolonged sedentary work.

実験的：VR based posture correction
Participants in this group will receive a virtual reality-based posture correction program in addition to conventional physiotherapy exercises for low back pain management and balance improvement.
|
Participants in the intervention group will receive a virtual reality (VR)-based training program in addition to conventional physiotherapy. The intervention will consist of 12 treatment sessions, administered 3 times per week for 4 consecutive weeks. Each session will last approximately 30-35 minutes. The VR training will be delivered using commercially available exergaming and VR-based fitness applications, including Fit Beat Combat, Holo-point , and the EIR Training Fitness Program. These applications are designed to provide interactive, task-oriented exercises that challenge balance, coordination, postural control, and lower limb motor performance through engaging gameplay environments. Participants will be supervised during all sessions to ensure safety and proper performance of movements, and exercise intensity will be adjusted according to the participant's tolerance and performance. |

アクティブコンパレータ：pamphlet based ergonomics
Participants in this group will receive conventional physiotherapy exercises and posture correction training without virtual reality intervention.
|
Participants in the control group will receive a standardized educational pamphlet focusing on posture correction, ergonomic principles, and recommendations for maintaining proper body mechanics during daily activities and desk work. The pamphlet includes illustrated instructions and general advice aimed at reducing musculoskeletal strain. In addition, participants will attend a brief weekly educational and follow-up session conducted at their workplace, where key posture and ergonomic principles are reinforced and any questions are addressed. Furthermore, participants will be added to a daily reminder group (e.g., messaging group) to receive regular prompts and reminders to adhere to the recommended posture guidelines and exercises outlined in the pamphlet throughout the 4-week intervention period. |

pain intensity
時間枠：baseline and 4 weeks
|
Pain intensity will be measured using the Visual Analog Scale (VAS), a 10-cm horizontal line anchored by "no pain" (0) and "worst imaginable pain" (10).
Participants will indicate their perceived level of low back pain.
Higher scores indicate greater pain intensity.

functional disability
時間枠：baseline and 4 weeks
|
Functional disability will be assessed using the Oswestry Disability Index (ODI), a self-reported questionnaire consisting of 10 items evaluating limitations in daily activities.
Total scores range from 0 to 100%, with higher scores indicating greater disability.
