Linear Correlation analysis between path lengths (ML, AP and Total) calculated using the FP and WBB. Data for HS and MS and for both testing conditions (eyes-open and eyes-closed) have been pooled together in this analysis. Parameters of the fitting (p-value, R², Slope and Intercept of the fitting) are presented in the plot for each analysis. WBB and FP present similar linear trends for both ML and AP COP directions, consistent with an overestimation of the directional sway in the WBB with respect to FP
