Overview

ObjectiveTo investigate the effectiveness of videoconferencing exercise interventions for people with chronic diseases.DesignSystematic review incorporating meta-analysis.Data sourcesPubMed, Cinahl, MEDLINE, Web of Science, Embase and Scopus.Eligibility criteriaThe current literature was searched following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Trials analysing participants with chronic disease undergoing aerobic and/or resistance exercise training over videoconferencing, with exercise capacity and/or quality of life outcomes were included. Meta-analyses were conducted for between-group comparisons of exercise capacity and quality of life. Risk of bias was analysed using the Downs and Black quality checklist and the certainty of evidence with Grading of Recommendations, Assessment, Development and Evaluation (GRADE).ResultsThirty-two trials were included in this review, of which 12 were comparator trials. Small–moderate between-group (videoconferencing vs comparator) effects favouring videoconferencing were seen for studies using a non-exercising comparator for exercise capacity (standardised mean difference (SMD)=0.616, 95% CI 0.278 to 0.954; p=<0.001) and quality of life (SMD=0.400, 95% CI 0.099 to 0.701; p=0.009). Small effects favouring videoconferencing were observed for studies using an exercising comparator for quality of life (SMD=0.271, 95% CI 0.028 to 0.515; p=0.029) and exercise capacity (SMD=0.242, 95% CI 0.059 to 0.426; p=0.009). Moderate risk of bias was identified for included studies (16.3±3.6/28), with GRADE certainty ratings of ‘low’ (quality of life) and ‘moderate’ (exercise capacity). Session attendance was 70% and was reported in 23 trials. No serious adverse events relating to videoconferencing were found. Nine trials documented the total number of technical issues that occurred in 17% of the sessions. Positive satisfaction outcomes were associated with ease of access and usefulness of technology.ConclusionIn patients with chronic disease, videoconferencing exercise interventions appear to be feasible and effective for improving exercise capacity and quality of life. More robust methodology is needed in future studies to improve the certainty of the evidence.PROSPERO registration numberCRD42020191243.
