Reliability of three functional tests via remote assessment for Post–Covid-19 patients

Introduction: At the era of pandemic, telerehabilitation (TR) is widely spread. However, remote assessment before entering at TR program is not so common due to limited research on reliable functional tests. Aim: To assess reliability of the Short Physical Performance Battery (SPPB), the 1-minute Sit to Stand test (1-min STS) and the Chester Step Test (CST) via remote assessment in Post–Covid-19 patients. Methods: 20 patients with Post–Covid-19 syndrome (mean age 52±10 years) with median 19 (IQR:10-29) days of hospitalization, median 241 (IQR:124-281) days after infection, mean CAT score 13±7 units and median Post-Covid-19 Functional Status Scale 1.5 (IQR:1-2) units, were randomly performed the functional tests via remote assessment using the Vsee platform at home and via face-to-face assessment at the rehabilitation center, with 2-5 days apart. One day before remote assessment, all participants had a 1-hour guidance session regarding Vsee use and home equipment proper preparation. Results: Between two occasions high correlations were found in walking (r=.712, pConclusion: Remote functional assessment for SPPB, 1-min STS and CST is feasible, valid, and reliable for Post–Covid-19 patients.
