Implications of log-transforming center of pressure and head position data during quasi-quiet standing

Description

This study evaluated agreement between postural sway derived from a force platform and head sway derived from the HTC Vive Pro headset in 37 adults. The uploaded files include: sample demographics, postural sway, head sway We calculated directional path, root mean square velocity, variance and power spectral density in 4 frequency segments. We then looked at correlations, ICCs and bland altman plots with and without logarithmic transformation.
