Post-acute physical therapy for a patient with critical illness associated with COVID-19: A case report

The COVID-19 pandemic is expected to bring a surge of survivors in need of post-acute rehabilitation. Preliminary research and clinical guidelines suggest patients recovering from critical illness associated with COVID-19 will present compromised function similar to acute respiratory distress syndrome (ARDS) and ICU-acquired weakness (ICUAW). However, information regarding physical therapy and progressions of physiological and functional outcomes is currently limited. This case report describes the course of recovery of a patient without significant preexisting medical conditions.

The patient RW (male, age 56) tested positive for COVID-19, and was admitted to ICU for 29 days. After weaning off mechanical ventilation after 2 months of hospitalization, he was transferred to our post-acute rehabilitation facility to recover from the residual effects. Physical therapy evaluation showed that while the patient was cognitively alert, he exhibited impaired general strength and activity intolerance due to severe exertional dyspnea. The patient received physical therapy aimed at improving his functional capacity. During his 16-day stay, the patient was able to significantly improve his capacities (i.e. 600% increase in 30-second chair stand test, 69.5% improvement in walking distance in 6-minute walk test, and 132.4% longer time to exhaustion during level ground ambulation). Dyspnea remained the main factor that limited his activities.

This case demonstrated that post-acute physical therapy appeared to be effective and safe in improving function after critical illness due to COVID-19 for this patient. Physical therapists are encouraged to closely monitor respiratory parameters such as heart rate, oxygen saturation, and levels of dyspnea during treatment for patient response and decisions regarding activity progression.
