The primary aims of the present study were to characterize the objectively measured Physical Activity (PA) in a cohort of previously hospitalized patients with moderate (no need for ICU admission) to severe (need for ICU admission) COVID-19 in Belgium at 12 months post discharge and to compare these PA outcomes with age- and sex-matched healthy controls and to additionally compare PA outcomes in a subset of patients with these of their own partners. Secondly, the impact of ICU admission and associations between physical function and PA were investigated in the patient cohort.
