Physical Therapy for a Multiple Myeloma Patient with COVID-19: A Case Report

This case report describes the successful management of rehabilitation therapy for a hematological malignancy patient who was receiving chemotherapy and had coronavirus disease 2019 (COVID-19).

A 76-year-old man receiving chemotherapy for relapsed refractory multiple myeloma (MM) presented to our hospital with fever and dyspnea and was hospitalized with a diagnosis of COVID-19. Physical therapy (20 min/day, 5 days/week) was started on day 6 of hospitalization while the patient was receiving oxygen therapy. Conditioning exercises and movement exercises were performed in an isolation room, and blood counts, fracture susceptibility, and respiratory status were monitored. The patient was severely immunocompromised and required 34 days of isolation due to persistent severe acute respiratory syndrome coronavirus 2 virus (SARS-CoV-2) infection. Physical function was assessed by manual muscle testing of the lower extremities and by the extent of lower extremity fatigue and dyspnea on exertion, as assessed using the Borg scale. Motor capacity was assessed using the de Morton Mobility Index (DEMMI) score and the Barthel Index (BI). Muscle weakness and severe dyspnea developed 4 days after physical therapy was started. However, physical therapy led to improvements in DEMMI score and BI. The patient was discharged home on day 43 with home medical care.

Careful management of MM and COVID-19 facilitated safe treatment with physical therapy. The patient's physical function improved with a carefully planned physical therapy program. Moreover, the patient required prolonged isolation due to persistent viral shedding; however, as a result of the treatment, which was coordinated between physicians and nurses, the patient could be discharged home.
