Key result
Tele-yoga therapy improved six-minute walk distance similarly to tele-pulmonary rehabilitation in patients with COPD, with no significant difference between the groups (p=0.333).
Why the study?
Yoga is beneficial in COPD, but well-designed comparative studies between pulmonary rehabilitation and yoga delivered as supervised tele-interventions are lacking.

Tele-yoga therapy is a safe and effective alternative to tele-pulmonary rehabilitation for improving exercise capacity and symptom scores in patients with COPD.
Tele-yoga offers a comparable alternative to tele-pulmonary rehabilitation for COPD exercise capacity; extends evidence for remote rehabilitation options.
Background In chronic obstructive pulmonary disease (COPD), pulmonary rehabilitation (PR) is an integral component of the non-pharmacological management of COPD. Yoga has proven to be beneficial in COPD, although well-designed comparative studies between the two modalities are lacking. This pilot study aims to compare these two modalities delivered as supervised tele-intervention. Methods The outpatient department (OPD) of a tertiary hospital recruited consenting, consecutive, inclusion-eligible COPD participants who were randomly assigned to intervention and control arms of 30 patients each. The intervention arm received a 45-minute tele-yoga therapy module (T-YT) validated by content validity ratio (CVR), computed using Lawshe's methodology and responses from 24 yoga specialists. The control arm received a 45-minute standardized tele-pulmonary rehabilitation session (T-PR). T-YT and T-PR were both managed through an online portal. Exercise capacity as measured by the six-minute walk distance (6MWD), symptom score (COPD assessment test [CAT], modified medical research council [mMRC]), forced expiratory volume in one second (FEV1%), quality of life (QoL) scores, St. George respiratory questionnaire (SGRQ), depression and anxiety scores (patient health questionnaire [PHQ-9] and generalized anxiety disorder scale [GAD-7] scores), were recorded at baseline and at the end of three months. Results 6MWD, symptom scores, SGRQ, PHQ-9, and GAD-7 all improved significantly from baseline within each group, but there was no statistically significant difference between the groups. FEV1% did not differ significantly between or among groups. This study shows T-YT module can be a reasonable substitute for T-PR in patients with COPD. Conclusions T-YT is beneficial in patients of COPD in terms of exercise capacity, symptom scores, and depression and anxiety scores and can be a reasonable alternative to T-PR.

Malik et al. (2022) conducted an RCT in Chronic Obstructive Pulmonary Disease (n=60). Tele-yoga therapy vs. Tele-pulmonary rehabilitation was evaluated on Exercise capacity measured by six-minute walk distance (6MWD) (p=0.333). Tele-yoga therapy improved six-minute walk distance similarly to tele-pulmonary rehabilitation in patients with COPD, with no significant difference between the groups (p=0.333).
