During the COVID-19 pandemic, face-to-face assessments were limited. Fortunately, older adults have access to web-technology (60%). Thus, we aimed to explore if assessing physical performance remotely is as reliable and valid as in person. At the end of the first lockdown, 15 older adults agreed to perform two similar evaluations in remote and face-to-face conditions. Functional capacities [5-repetitions Sit-to-Stand (STS); unipodal balance, 4-m walking speed (normal (NWS); fast (FWS)), 3-m Timed-Up and Go (normal (nTUG); fast (fTUG))] and muscle power and endurance were assessed. Fast walking speed was moderately reliable. Unipodal balance, NWS and nTUG were highly reliable (ICC>0.7). fTUG, STS, muscle endurance and power were extremely reliable (ICC>0.9). For absolute reliability, SEM varied from 15.54 to 5.14%. Finally, the MDC varied from 43.07 to 14.21%. Assessing functional capacities and muscle function remotely is as reliable and valid as a face-to-face assessment and should be considered as a clinical practice.
