Factorial analysis of Model-based parameters. a Correlation matrix for the Model-based parameters. b Three-dimensional factor representation of the Model-based parameters.
Pink, black, and green lines code the parameters associated with factor 1, factor 2, and factor 3, respectively. Blue lines code the parameters that are “shared” across factors. c Right: correlation matrix between factors and clinical scores. The colorbar is the same of panel (a). MASs and MASe abbreviate MAS shoulder and MAS elbow, respectively. Left: Scatter plots of the correlation between the three main factors and the clinical scores. d Temporal evolution of the three factors for sub-acute (top row) and chronic patients (bottom row). Each point represents the value of the factor for each session averaged across patients. Thick lines represent the results of the fitting of experimental data (i.e., linear, exponential or double exponential). Y-axis scales are different for each factor and patients group
