Virtual Reality is Effective in the Management of Chronic Low Back Ache in Adults: a Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND:Chronic low back ache (CLBA) is a common condition that is conventionally managed with physical therapy and analgesics. Recently, virtual reality-based interventions have been tried out in the management of CLBA. Their effectiveness, however has not been established. This meta-analysis aims to find out if the application of VR will lead to better pain relief, as compared to conventional techniques in adults with CLBA.METHODS:The literature search was carried out in three online databases for potential randomized controlled trials that compared VR-based interventions with conventional treatment in CLBA. Data on outcome parameters were recorded. Meta-analysis was carried out with the help of appropriate software.RESULTS:Seven studies having data on 507 subjects were included in the meta-analysis. Their mean ages were 48.4 years. There were 252 subjects in the VR group and 255 in the control group. VR-based interventions were found to have a statistically significant improvement in the pain intensity compared with conventional techniques (p - 0.005).CONCLUSION:VR-based interventions are effective in the management of CLBA in the short term. Further research with longer follow-up is required to evaluate if these improvements are persistent in the long term.
