The COVID-19 pandemic has caused distress for healthcare providers due to the respiratory problems it causes, among others. In this situation, rehabilitation of the respiratory system has been suggested and implemented in different COVID-19 patients. This study evaluated the feasibility and effectiveness of a novel program based on breathing exercises through telerehabilitation tools in COVID-19 patients with mild to moderate symptomatology in the acute stage. Forty subjects were randomized in an experimental group, based on pulmonary rehabilitation, and in a control group, of which the subjects did not perform physical activity. Thirty-eight subjects, with nineteen in each group, completed the one-week intervention. We performed measurements using the Six-Minute Walk Test, Multidimensional Dyspnoea-12, Thirty-Second Sit-To-Stand Test, and Borg Scale. Both groups were comparable at baseline. Significant differences were found for all of the outcome measures in favour of the experimental group. Ninety percent adherence was found in our program. A one-week telerehabilitation program based on respiratory exercises is effective, safe, and feasible in COVID-19 patients with mild to moderate symptomatology in the acute stage.
