Aim: To investigate the knowledge and attitudes of Greek physiotherapists regarding functional assessment tests used in the rehabilitation of post-COVID-19 patients.

Methods: Based on the literature, a specific 27-question questionnaire was designed and divided into 3 sections: a) sources of information about the management of patients with post-COVID-19 symptomatology, b) functional assessment tests most commonly used in clinical practice, c) willingness for further knowledge on performing functional tests. Inclusion criteria for completing the questionnaire were: a) physiotherapy profession, b) involvement with post-COVID-19 patients’ treatment in the last year. The completion of the questionnaire was anonymous. It was shared in Google Forms format, via personal email invitations and public sharing on social media by all researchers, with republishing ability by each user. Sharing was conducted over two periods, lasting 16 and 13 days, respectively.

Results: The study included 82 physiotherapists (28 men and 54 women), 56.1% of whom were less than 39 years old and 50% had more than 10 years of professional experience. The main sources of information on rehabilitation in post-COVID-19 patients were journal publications (69.6%). Among the most well-known and frequently used tests were the six-minute walk test (85.4%), the one-minute sit-to-stand test (86.6%), and the timed up-and-go test (76.9%). A large percentage of physiotherapists used functional assessment tests before initiation (80.5%) and at the end (70.8%) of the treatment program. The 91.5% expressed the willingness for further education on practicing functional tests.

Conclusions: Greek physiotherapists get information from the recent literature and use well-known functional tests for assessing functional capacity in post-COVID-19 patients.
