This study assessed the use of remote rehabilitation therapy for coronavirus disease (COVID-19) patients from 24 April to 24 May 2020. A rehabilitation modality was devised that can be applied remotely (from a distance) and over long durations using a mobile terminal. This allowed a final total of 18 out of 43 COVID-19 patients to be treated indirectly by remote rehabilitation. The patients on remote rehabilitation were significantly younger than those undergoing direct rehabilitation. Four patients were switched from direct to remote rehabilitation during the study. Three out of 12 patients who required intubation underwent remote rehabilitation, and 1 extracorporeal membrane oxygenation survivor underwent direct rehabilitation. All patients undergoing remote rehabilitation were discharged home or to a hotel. Twelve out of 29 patients were transferred to a rehabilitation hospital due to delayed recovery of activities of daily living. No serious adverse events were observed. Remote rehabilitation was effective, and safe against the transmission of infection, and could improve delivery of rehabilitation to patients in COVID-19 zones.
