Application of a home-based exercise program combined with tele-rehabilitation in previously hospitalized patients with COVID-19: A feasibility, single-cohort interventional study

INTRODUCTION Telehealth for COVID-19 patients is still limited. We aimed to assess the clinical effects of a home-based tele-rehabilitation exercise program following hospital discharge during the first lockdown in Greece, April to July 2020. METHODS A pre-and post-intervention design was applied in two stages. Firstly, patients were instructed to use a specially designed for COVID-19, e-book during four tele-health sessions. Afterwards, a 2-month home-based program consisted of self-practice exercise and one-hour supervised tele-rehabilitation exercise sessions every 10 days, was delivered. At baseline and at the end of the program, participants were interviewed about their physical, psychological status and quality of life (QoL) during the post-hospitalization period. The IPAQ-Gr, the HADS and the SF-36 questionnaires were used, respectively, and the participants were functionally assessed via teleconferences, using the 60 sec Sit to Stand Test (60secSTS), the Short Physical Performance Battery (SPPB) and the 3 min Step Test (3MST). RESULTS Seventy-four patients, median age 52.5 (IQR: 43–61) years were included at the first stage. From those, only 22 patients, mean ± SD age 50.1 ± 13.2 years completed the 2-month exercise program. The training program was well tolerated by all 22 patients. The mean number of unsupervised exercise sessions was 18.4 ± 3.5. No adverse effects were observed either during initial and follow-up assessment via tele-communication or during home-exercise sessions. Training improved significantly (p<0.001) lower limb muscle performance [median (IQR) 60secSTS: 22 (20–26) to 31 (25–36)], anxiety [median (IQR) HADS: 9 (6–13) to 4.3 (3.2–9.6)], depression [median (IQR) HADS: 5 (3–8) to 1.8 (0.9–3.7)], QoL [mean ± SD SF-36pcs: 37.5 ± 10.3 to 52.1 ± 6, and mean ± SD SF-36mcs: 42.9 ± 11.6 to 45.5 ± 12.3]. CONCLUSIONS Tele-rehabilitation may be feasible and may improve physical and psychological status of COVID-19 patients after hospital discharge. © 2022 Kortianou E. et al.
