The intervention effect of virtual reality technology on patients recovering from traumatic brain injury: a meta analysis

Objective:To systematically evaluate the intervention effect of virtual reality technology on patients recovering from traumatic brain injury.Methods:The computer retrieved CNKI,VIP,Wan Fang,Embase,The Cochrane Library and PubMed database,and collected randomized controlled trials of virtual reality technology combined with routine rehabilitation training and simple routine rehabilitation training on patients recovering from traumatic brain injury.The retrieval period was from the establishment of the database to July 2019.Two researchers independently screened the literature,extracted the data and evaluated the risk of bias in the included studies.RevMan 5.3 software was used for analysis.Results:A total of 7 articles were included.Meta-analysis results showed that virtual reality technology could significantly improve balance function(mean difference(MD)=3.72,95%confidence interval(CI)(2.61,4.83),P<0.001),daily living ability(MD=11.87,95%CI(10.42,13.32),P<0.001),and exercise ability(MD=3.83,95%CI(2.30,5.36),P<0.001).In the aspect of posture control ability,the trajectory motion length,trajectory velocity and peripheral area were improved(standardised mean difference(SMD)=0.80,95%CI(1.19,0.41),P<0.0001),(SMD=0.95,95%CI(1.45,0.45),P=0.0002),(SMD=0.69,95%CI(1.11,0.26),P=0.001).Conclusion:Virtual reality technology can significantly improve the balance function,daily living ability,motor function and postural control ability of patients recovering from cerebral trauma.Limited by the quantity and quality of the included studies,the above conclusions need to be verified by more high-quality studies.
