Abstract:

PURPOSE OF REVIEW: Assessment of the musculoskeletal system requires consideration of its integrated function with the nervous system. This may be assisted by using valid and reliable methods that simulate real-life situations. Interactive virtual reality (VR) technology may introduce various auditory and visual inputs that mimic real-life scenarios. However, evidence supporting the quality and strength of evidence regarding the adequacy of its psychometric properties in assessing the musculoskeletal function has not been evaluated yet. Therefore, this study reviewed the validity and reliability of VR games and real-time feedback in assessing the musculoskeletal system.

RECENT FINDINGS: Nine studies were included in quality assessment. Based on outcome measures, studies were categorized into range of motion (ROM), balance, reaction time, and cervical motion velocity and accuracy. The majority of the studies were of moderate quality and provided evidence of VR adequate concurrent and, in some cases, known-groups validity. Also, VR showed high intra-rater reliability for most of the measured outcomes. Based on the included studies, there is a limited promising evidence that interactive VR using games or real-time feedback is highly valid and reliable in assessing ROM in asymptomatic participants and patients with chronic neck pain and radial fracture. For the remaining outcomes, evidence is limited to draw a robust conclusion. Future studies are recommended to test VR psychometric properties in different patients' population using a rigor research methodology.
