Evaluating the Effectiveness of Global Postural Re-Education and Virtual Reality Techniques in Reducing Work-Related Stress

Work-related stress is one of the most important health problems arising from the interaction between workers and the psychosocial conditions of their work environment. One of its most common physical consequences is musculoskeletal pain, especially in the back and neck. This study analyzes the effectiveness of an intervention program combining Global Postural Re-Education and Virtual Reality techniques to improve psychosocial working conditions and overall mental health. A quasi-experimental design was implemented with four independent groups: virtual reality alone, postural re-education with a hammock-type device, a combination of virtual reality and postural re-education, and rest break with music (placebo). The CarMen-Q questionnaire was used to assess psychosocial work factors, while the GHQ-28 was administered to evaluate general mental health. Forty-four participants completed ten intervention sessions over two consecutive weeks. The results showed a significant overall improvement in perceived work conditions and mental health after participation. The combined VR + RPG condition produced the greatest reduction in emotional demands and performance pressure, whereas the simple rest condition yielded the greatest improvement in psychological well-being. These findings suggest that brief interventions integrating physical and cognitive relaxation components can effectively reduce work-related stress and promote occupational well-being.
