Parameters computed from the CoP trajectory acquired during the Romberg Test in the EO condition for post-stroke (SS, second column) and control subjects (CS, third column). All parameters were significantly different between SS and CS, as indicated by the p-values on the right-hand side column (the asterisks mark the values exceeding the threshold for significance, p < 0.05). Values are reported as mean ± standard deviation.
