Correlations and score differences between BBT, BBT-VR-C, BBT-VR-HT and MD-MR. (a). In this correlation plot, each point represents paretic hand’s score obtained when performing the BBT in relation to the BBT-VR-HT score. Pearson correlation coefficients (r) and their p-value (p) are presented at the left side of the graph. A linear regression is plotted in blue. (b). In this correlation plot, each point represents paretic hand’s score obtained when performing the BBT in relation to the BBT-VR-HT score. Pearson correlation coefficients (r) and their p-value (p) are presented at the left side of the graph. A linear regression is plotted in blue. (c). In this correlation plot, each point represents paretic hand’s score obtained when performing the BBT in relation to the MD-MR score. Pearson correlation coefficients (r) and their p-value (p) are presented at the left side of the graph. A linear regression is plotted in blue. (d). In this plot, HCP and IHP’ mean BBT, BBT-VR-C, BBT-VR-HT and MD-MR scores are presented as histograms with error bars. Each error bar represents the positive standard deviation of the given test’s score. The * corresponds to a significant difference
