Fig. 3

a Scatter-plot showing the relationship between improvements in RMT in the ipsilesional-hemisphere and improvements in functional performance of the distal-component pre-to-post-therapy for individual patient’s data. Greater decreases in motor-threshold tend to show greater increases in FMW/H. Red Line (RG) and the blue line (CG) represents a linear-trend in improvement in distal motor-outcome (∆FMW/H) score as a function of change in the ipsilesional-hemisphere (∆RMTipsi) in RG and CG pre-to-post-therapy in which RG shows a significant correlation (r = 0.64, F = 7.24, p = 0.022), b Scatter-plot showing the relationship between change in RMT asymmetry-ratio (ipsilesional/contralesional) pre-to-post-therapy and functional performance of distal-component for individual patient’s data. Greater decreases in motor-threshold tend to show greater increases in FMW/H. The red line (RG) and the blue line (CG) represents a linear-trend in improvement in distal motor-outcome (∆FMW/H) score as a function of change in RMT-ratio (∆RMTasymm-ratio) in RG and CG pre-to-post-therapy in which RG shows a significant correlation (r = 0.6, F = 5.77, p = 0.03)
