Effect of Rehabilitation Nutrition on a Post-Acute Severe COVID-19 Patient: A Case Report.

Coronavirus disease 2019 (COVID-19) may lead to post-acute physical function deterioration due to intensive-care-unit-acquired weakness-related sarcopenia and dyspnea. Limited reports have examined the effects of rehabilitation and nutritional therapy on patients with post-acute COVID-19. We present the case of a 67-year-old man, who was admitted for the treatment of post-acute severe COVID-19, who benefited from rehabilitation nutrition. When the patient's condition stabilized, sarcopenia and malnutrition were observed, and rehabilitation nutrition was implemented. The physical therapist implemented a program focused mainly on resistance training and aerobic exercise, and the dietitian provided oral nutritional supplements and hospital food that met the patient's energy and protein intake requirements. Comparing the initial evaluations with those at discharge, factors affecting nutritional status, such as body mass index and skeletal muscle mass index, and physical functions, such as grip strength and walking speed, and dyspnea, had improved. The patient was discharged and returned to work. This case suggests improvements in the nutritional status and physical functions of post-acute severe COVID-19 patients by interventions following rehabilitation nutrition.
