Virtual reality for COPD exacerbation: A randomized controlled trial

Abstract

BackgroundPulmonary rehabilitation (PR) is an effective treatment method for chronic obstructive pulmonary disease (COPD). However, individuals with chronic diseases that require lifelong treatment and experience exacerbations need motivational methods. ObjectivesThe aim of this study was to examine the effects of virtual reality on symptoms, daily living activity, functional capacity, anxiety and depression levels in COPD exacerbation. MethodsFifty patients hospitalized for COPD exacerbation were included in the study. They were randomly assigned to two groups. Twenty-five patients participated in a traditional PR (once-daily until discharge), including pedaling exercises. The second/25 patients followed the same protocol but experienced cycling simulation in the forest via virtual reality (VR + PR). All patients were evaluated using 1-minute/Sit-to-Stand test (STST), modified-Medical Research Council (mMRC) scale, COPD Assessment test (CAT), Hospital Anxiety and Depression Scale (HADS), and London Chest Activities of Daily Living (LCADL) before and after the treatment. ResultsThe STST showed an increase in both groups post-treatment, notably higher in the VR + PR (p = 0.037). Dyspnea levels and CAT scores decreased in all patients, but the decrease was greater in the PR + VR group for both parameters (p = 0.062, p = 0.003; respectively). Both groups experienced a reduction in the HADS scores compared to the pre-treatment, with a more significant decrease in depression and the total score in the VR + PR (p < 0.05). LCADL's sub-parameters and total score, excluding household, decreased in both groups after treatment (p < 0.05). The improvement was more substantial in the VR + PR. ConclusionsVirtual reality provides benefits in the management of COPD exacerbations and can be used safely.
