Background: Balance training is an important aspect in prevention and rehabilitation of musculoskeletal lower limb injuries. Virtual reality (VR) is a promising addition or alternative to traditional training. This review aims to provide a comprehensive overview of VR technology and games employed for balance prevention and rehabilitation, balance outcome measures, and effects for both balance prevention and balance rehabilitation following musculoskeletal lower limb impairments.
Methods: A systematic literature search was conducted in electronic databases to identify all related articles with a longitudinal study design on VR, balance, and prevention or musculoskeletal rehabilitation of the lower limbs in adult subjects between 19 and 65 years.
Results: Eleven articles concerning balance prevention and five articles regarding balance rehabilitation were included. All studies used screen-based VR and off-the-shelf gaming consoles with accompanying games. The Star Excursion Balance Test (SEBT) was the most frequently used outcome measure. Two studies found positive effects of VR balance training in healthy adults, while none reported negative effects. None of the included studies showed a significant difference in balance performance after a VR balance rehabilitation intervention compared to traditional balance training.
Conclusion: Few studies have been published concerning musculoskeletal balance rehabilitation and balance prevention in healthy adult subjects. However, the studies published have shown that VR exercises are equally effective compared to traditional balance training for both domains of application. As there is large variability between studies, recommendations for future research are given to prospectively investigate the use of VR technology for balance training.
