Effect of Teleyoga Before COVID-19 and During Pandemic: A Narrative Review

Background: Yoga plays a beneficial adjunctive role in various disorders due to its physiological and psychological benefits. COVID-19 pandemic led to a paradigm shift in delivery of health interventions from on-site to online/ tele-intervention mode. Focus shifted to tele-yoga as a reasonable and feasible alternative to in-person yoga. Studies have evaluated its effect among patients suffering from various disorders, their care givers, healthcare workers, and the general public. We have assessed the effect of tele- Yoga, including its appropriateness, acceptability, and benefits, via this narrative review. Methods: We searched PubMed data base using predefined keywords. Inclusion criteria included controlled trials and Randomized Controlled Trials (RCTs) which are completed and published in English language up to February 2022 with tele-yoga/online yoga as part of intervention. Exclusion criteria included articles in other language or articles whose full text is unavailable. Results: After removing duplications and reviewing articles based on title, abstracts, and available full texts, seven studies with 391 participants were included. Majority of the trials took place in United States, with United Kingdom, Canada, and India following closely behind. Yoga can be safely administered via various online /tele interventions in both diseased and healthy individuls. Tele yoga or modules incorporating tele-yoga has been shown to improve symptoms like dyspnea, psychiatric/psychological burden including stress, anxiety and depression levels and may promote positive effects like spirituality. Conclusion: Tele-yoga is feasible and beneficial in healthy and diseased individuals. Larger well-designed RCTs comparing in-person yoga with tele-yoga are needed to ascertain their full benefits.
