The magnitude squared (1st and 3rd column) and phase (2nd and 4th column) of the coherence between perturbation and CoM movement as a function of frequency (Hz) averaged across MS (grey dashed) and control (black) participants. The visual perturbation driving frequencies are shown by the dotted grey vertical lines for the object (tree, left) and scene (right). Results are shown for each of the Coherence Stimulus Conditions (‘Tree Low’, ‘Scene Low’, ‘Scene High’, ‘Combined’). A significant main effect of Coherence Stimulus Condition was found and is presented in the Results
