Left panels: Representative of the center-of-foot pressure trace during the dynamic balance of a patient with open (top) and closed (bottom) eyes. The oscillation ranges in the antero-posterior (AP) and medio-lateral (ML) directions were quantified by projecting the angular displacement of the platform on a plane. The sway path is the length of the trajectory. Middle panel: Median (symbols) and interquartile range (whiskers) of the ML (x-axis) and AP (y-axis) of overall post-COVID syndrome patients (triangles), also splint in hospitalized (circles) and non-hospitalized (squares) patients, with open eyes (OE, open symbols) and closed eyes (CE, close symbols). *, ***: p < 0.05, 0.001 hospitalized vs non-hospitalized patients; °°°: p < 0.001 CE vs OE. Right panel: Median (symbols) and interquartile range (whiskers) of the sway path of overall post-COVID syndrome patients (triangles), also splint in hospitalized (circles) and non-hospitalized (squares) patients, with open eyes (OE, open symbols) and closed eyes (CE, close symbols). ***: p < 0.001 hospitalized vs non-hospitalized patients; °°°: p < 0.001 CE vs OE
