Introduction. Almost all patients, who have experienced acute manifestations of COVID-19, regardless of the severity of the acute phase of the disease, are only at the beginning of a long way to recovery. According to experts, SARS-CoV-2 infection should affect almost 80% of the world's population, so all these patients to a greater or lesser extent will need a rehabilitation of certain manifestations of postcovid syndrome.

Purpose: to study the effectiveness of rehabilitation program and the dynamics of cognitive impair- ment and manifestations of chronic fatigue syndrome in patients after coronavirus disease.

Methods: The study design included 60 patients after SARS-Cov-2 infection. Among the examined patients there were 26 (43,3%) women and 34 (56,7%) men. An average age of the patients was 43,9±1,08 years. Patients were referred to the Department of Physical Rehabilitation after corona- virus disease with chronic fatigue and cognitive disorders syndromes. Accordingly, all patients, who participated in the study, were divided into two groups: group I - 28 patients with a general condition of moderate severity at the hospital stage and 32 patients - group II, with severe course of the disease and oxygen demand at the hospital stage. Depending on the duration of rehabilitation, two observation periods were used - on the 7th and 14th day of rehabilitation program.

Results: It has been proven, that patients, who didn’t need oxygen, were complaining about anos- mia, cephalgia, cognitive impairment, increased anxiety and fatigue. Dysgeusia, dyssomnia, and depression were more common in patients, requiring oxygen therapy at the hospital stage. Rehabil- itation program eliminated cognitive dysfunction, depression, cephalgia, drowsiness and dyssom- nia on the 7th day in patients, who did not require oxygen therapy (p>0,05), and in patients, who needed oxygen therapy - on the 14th day of the rehabilitation program (p>0,05). However, 2 (6,3%) and 3 (9,4%) patients, who needed oxygen therapy, even after 14 days of rehabilitation had mani- festations of minor recurrent headache and drowsiness.

Conclusion: Thus, patients after coronavirus disease, who needed oxygen therapy at the hospital stage, need long-term rehabilitation program.
