Proprioceptive Weighting
PW ratio per subject + group comparison (HC vs cLBP)
Per-trial COP plots β to be added in a later iteration.

Each dot = one subject. Box = IQR (Q1βQ3); centre line = median; whiskers = full range. PW = TS / (TS + PS). Values above 0.5 indicate triceps-surae-dominant proprioception (ankle strategy); below 0.5 indicate paraspinal-dominant (hip strategy).
Each trial = 60 s recording. Vibration stimulus active 15β30 s (highlighted).
