The effect of virtual reality technology in exercise and lung functions of patients with chronic obstructive pulmonary disease: A systematic review and meta‐analysis

Abstract

AbstractBackgroundChronic obstructive pulmonary disease (COPD) is a serious chronic disease worldwide, with significant negative impacts on the quality of life, family economic burden, and social healthcare burden of patients.AimsThe aim of this study was to explore the effects of virtual reality technology on exercise function and lung function in COPD patients.MethodsA meta‐analysis of randomized controlled trials was utilized. PubMed, Embase, Cochrane Library, Web of Science, PsycINFO, CINAHL, Medline, Scopus, China National Knowledge Infrastructure (CNKI), Wanfang Database, Weipu Database (VIP), and Chinese Biomedical Database (CBM) were systematically searched. We included randomized controlled trials published from the establishment of the database to August 10, 2022, on virtual reality technology in COPD patients. Literature retrieval and screening was carried out independently by two reviewers to obtain literature that met our inclusion and exclusion criteria and to extract relevant data. Two reviewers assessed the risk of bias in the included literature. A meta‐analysis was performed using Revman 5.4 Software.ResultsA total of 10 randomized controlled trials with 539 participants were included. The results showed that virtual reality technology significantly improved the lung function of COPD patients, such as forced expiratory volume (FEV1; MD = 7.29, 95% CI [4.34, 10.24], p < .01) and forced expiratory volume/forced vital capacity (FEV1/FVC; MD = 6.71, 95% CI [4.72, 8.71], p < .01). The combined intervention with different virtual reality technology had different effects on motor function. Compared with endurance training (ET) alone, virtual reality technology combined with ET had no significant effect on the 6‐minute walk test (6WMT) in COPD patients (p > .05). Compared with pulmonary rehabilitation (PR) alone, virtual reality technology combined with PR was more effective in increasing 6WMT in COPD patients (MD = 30.80, 95% CI [10.85, 50.74], p < .01).Linking Evidence to ActionVirtual reality technology can help to improve lung function in COPD patients, and virtual reality combined with PR can improve exercise tolerance in COPD patients. However, due to the limited number of included studies, large‐sample, multicenter, high‐quality randomized controlled trial studies are needed to provide clear evidence.
