The Effect of Virtual Reality (VR) and Progressive Muscle Relaxation (PMR) in Stress Management Among Physiotherapy Students

Introduction:

As stress appears to be a natural human response to difficult situations prompting us to address challenges and threats in our lives, prolonged stress may cause the fight or flight response to over-ride body's normal physiology and produce multiple psychological and physiological symptoms resulting in various negative health conditions such as cardiovascular disorders, GIT disturbances, hypertension etc. Moreover, a global survey of adolescents in 72 countries found 66% of students reported feeling stressed about academics and 37% of students felt anxiety relating to schoolwork. Many stress reduction interventions such as Progressive Muscular Relaxation (PMR), mindfulness meditation, deep breathing exercises, and guided imagery have been shown to reduce stress levels among individuals and are being used as traditional relaxation interventions.

Progressive muscle relaxation (PMR) originally known as Jacobson Muscle Relaxation Technique, was developed by Edmund Jacobson in the 1934. It is an actively engaging technique guiding the patients to consciously contract muscles to create tension and release it progressively. This is repeated until patients acquire complete relaxation. Many studies on PMR have proven it to be beneficial in decreasing stress and anxiety levels in many adults as well as children worldwide.

With emerging technology, innovative ideas, such as the use of VR (Virtual Reality) for stress management, have also been considered and studied. According to Cruz-Neira (1993), Virtual reality refers to immersive, interactive, multisensory, viewer-centered, 3D computer generated environments and the combination of technologies required building environments. In the healthcare sector, VR has been proved beneficial for balance and cognition training in cerebral palsy and stroke, and also has been observed to mitigate acute and chronic pain. It can provide rehabilitation, motivation and entertainment all at once. Further studies on its immersive effect suggest it to be helpful in stress management. Natural environments (forests, beaches, mountains etc ) viewed through VR, have shown to help individuals reduce their stress levels, anxiety disorders, and phobias. However, there is little research on individual preferences of different VR landscapes.

In Asia, research relevant to VR has been shown to have a positive effect on stress management in individuals with high stress and mood disorders. Effect of forest and water landscapes on stress management has also been discussed earlier. However, area for more research still remains.
