Location of peak motor cortex activation. a Location of the anatomical search territory for knee and ankle task peak activations: pink shaded voxels. b Individual participant (squares) and group mean (x) loci of peak activation for the knee task collapsed across the X (medial/lateral) dimension for participants in the knee osteoarthritis (OA) (orange) and control (blue) groups. Data are presented on a Montreal Neurologic Institute (MNI) 1-mm template standard brain. Note that the group mean loci of peak activation for the OA group is anterior to that for the control group (p = 0.02), and the wide distribution of loci of peak activation for the knee task between individual participants across the search territory of the motor cortex (13 mm in the Y plane and 24 mm in the Z plane)
