Table 1 Mean ± standard deviation values for each features for each group (HS and MS) and measurement system (FP and WBB). The top table shows the results for the eyes-open condition, the bottom table for the eyes-closed condition. Results of statistical analysis (t-test, α = 0.05) is presented. Column FP - HS vs MS (p) presents the results of the statistical analysis between HS and MS populations for the data extracted using the FP. Column WBB - HS vs MS (p) presents the results of the statistical analysis between HS and MS populations for the data extracted using the WBB. Column HS - FP vs WBB (p) presents the results of the statistical analysis between FP and WBB for the HS population. Column MS- FP vs WBB (p) presents the results of the statistical analysis between FP and WBB for the MS population. For each column the p values are presented. * denotes p-value < 0.05; ** denotes a p-value < 0.01
