Effect of virtual reality technology as intervention for people with kinesiophobia: A meta‐analysis of randomised controlled trials

AIMS AND OBJECTIVE: To explore the effectiveness of Virtual Reality Technology in reducing kinesiophobia in people. BACKGROUND: Kinesiophobia is an important psychosocial factor affecting the pain experience and has a significant negative impact on rehabilitation. Virtual reality technology has been widely used in the treatment of phobias, mental disorders and anxiety disorders. However, the effect of virtual reality technology on people with kinesiophobia has been reported with inconsistent results. DESIGN: A meta-analysis of randomised controlled trials. METHODS: This study systematically searched PubMed, Web of Science, PsycINFO, CINAHL, Embase, Cochrane Library, Medline, Scopus and four Chinese databases. The standardised mean difference (SMD) was calculated using random-effects models, and the Cochrane Collaboration's tool was used to assess the risk of bias in each study. The PRISMA 2020 checklist provided by the EQUATOR network was used. RESULTS: Eleven randomised controlled trials involving a total of 488 subjects were included. Meta-analysis showed the effect sizes of virtual reality intervention on kinesiophobia (SMD = -0.53, 95% CI [-0.90, -0.17], p = .004). Virtual reality intervention was more effective in reducing kinesiophobia in people with chronic low back pain (SMD = -1.00, 95% CI [-1.71, -0.29], p = .006). Compared with fully immersive virtual reality (SMD = -0.29, 95% CI [-0.62, 0.05], p = 0.09), non-immersive virtual reality was more effective in reducing kinesiophobia (SMD = -0.66, 95% CI [-1.24, -0.09], p = 0.02). Compared with virtual reality intervention alone (SMD = -0.35, 95% CI [-1.40, 0.71], p = 0.52), virtual reality combined with exercise was more effective in reducing kinesiophobia (SMD = -0.59, 95% CI [-0.95, -0.22], p = 0.002). CONCLUSIONS: Virtual reality technology has the potential to reduce the degree of kinesiophobia in people. In addition, virtual reality technology was more effective in people with chronic low back pain; non-immersive virtual reality was more effective in reducing kinesiophobia; and virtual reality technology combined with exercise was more effective in reducing kinesiophobia than virtual reality intervention alone. Clinical nursing staff should be encouraged to use virtual reality to speed up patient recovery. However, to achieve immersion and apply this technology to different diseases, more studies are required to provide clearer suggestions. RELEVANCE TO CLINICAL PRACTICE: This study suggests that healthcare staff should pay attention to kinesiophobia, and early identification and intervention of kinesiophobia can help patients recover their health and improve the quality of nursing.
