Kinematic and neurophysiological results
The NHPT executed with the right and left hands was performed and kinematic indexes were detected, while a 3 × 3 General Linear Model was used for data analysis (see Material and Methods). The NHPT with the right hand revealed a Time by Group interaction for Peg-In-Hole time, while a Group effect was found for Peg-grasp time, mean velocity during peg-transfer and hand-return, and velocity peak during hand return (Table Between-group differences over time for kinematic indexes during Nine Hole Peg Test performed with the right hand (3 × 3 General Linear Model with Bonferroni post-hoc analysis). Data are shown as mean and standard deviation.*Between-group differences over time for kinematic indexes during Nine Hole Peg Test performed with the left hand (3 × 3 General Linear Model with Bonferroni post-hoc analysis).
