Outpatient rehabilitation in post-acute COVID-19 patients: a combined progressive treatment protocol

Abstract

Purpose to investigate the effectiveness of a 4-week combined progressive program on functional abilities, disability status and quality of life (QoL) in COVID-19 recovered patients. Materials & Methods 18 COVID-19 recovered patients performed a combined rehabilitation treatment accounting for 12 sessions, including both respiratory and motor training sessions. A careful monitoring of exercise intensity, duration and progression to tailor complexity evolution on patients’ competencies was carried out. Patients were monitored with different functional scales and self-reported questionnaires before (T0) and after (T1) rehabilitation. Results 6-Minutes Walk Test, Timed Up and Go Test and Short Physical Performance Battery significantly improved, while Physiological Cost Index presented a significant reduction after rehabilitation. Moreover, Barthel Index significantly improved and patients presented significantly increased upper and lower limbs strength at T1. Furthermore, mMRC Dyspnoea Scale presented a significant reduction after training. Finally, physical and psychological well-being scales improved according to Short-Form 36; while, self-reported questionnaires related to mood and depression showed no significant modification after rehabilitation. Conclusions results evidenced the efficacy of the combined progressive intervention in COVID-19 recovered patients. The specific customization on patients’ needs and the careful exercise monitoring promoted improvements on functional abilities and disability status, with positive impact on QoL.
