Linear regression analysis across movements of the different DoFs of the hand (configuration B) during the turning page and tripod grasp tasks.

The coefficients of determination, R2, are displayed. All R2 values are statistically significant (p < 0.05). (a) Pairwise comparison between all DoFs recorded by the glove; each datum is the average of three trials. (b) Comparison of aggregated R2 values across tasks. Asterisks denote the cases in which the data for the turning page and tripod grasp were significantly different from the other tasks; one-way ANOVA F(5,174) = 6,24, p = 2.3∙10−5; post-hoc pairwise comparisons with Bonferroni correction [turning page different from light object (p = 0.034), extension grasp (p = 0.018), lateral grasp (p = 0.01) and carton pouring (p = 0.038); tripod grasp different from light object (p = 0.008), extension grasp (p = 0.007), lateral grasp (p = 0.028) and carton pouring (p = 0.008)].
