Use of sit-to-stand test to assess the physical capacity and exertional desaturation in patients post COVID-19.

We propose the use of the 1-minute sit-to-stand test (1STST) to evaluate the physical capacity and exertional desaturation one month after discharge in a sample of patients who survived COVID-19 pneumonia. This was a cross-sectional study that collected routine data from consecutive patients admitted to the outpatient program in a public hospital in Chile. Patients were asked to complete a 1STST.
