Postural sway
The postural sway parameters calculated for bipedal standing
trials (in presence or absence of visual input) are reported in
Table 2. All of them exhibit good within-day and between-day
reliability with Intraclass Correlation Coefficient (ICC) in the
0.77–0.90 range for the eyes open condition and 0.72–0.84 for the
eyes closed condition. Unipedal results were not considered
for further analysis because a relevant number of participants of
both groups were unable to complete the test at T0.
