Correlation between CoP displacement and trunk acceleration in the antero-posterior (AP) and medio-lateral (ML) directions, and between phase durations (Δt) measured by force plates and wearable sensors. Pearson’s correlation coefficients (r) and the correspondent p-values are reported. Significant correlations (p-value < 0.05) are marked with *.
