Partial least squares (PLS) component loadings. a loadings of the latent variables of the response variables (percent normalized change in gait parameters) where the components are in the x-axis. b loadings of the latent variables of the predictor variables (mean lobular electric field strength) where the components are in the x-axis. c contrast in mean lobular electric field strength (V/m) for 10 participants between the dentate and the leg lobules VII-IX ctDCS montages. ‘Contra’ is contra-lesional and ‘Ipsi’ is ipsi-lesional
