A Kinematic metrics during reaching distally per task across subjects (N = 31). The metric expressions are presented in boxplots per task. The vertical black line in each subplot separates the grasp movement tasks on the left side and gesture movement tasks on the right side. Statistically significant comparable metrics across tasks are indicated by asterisks and the bold notation of the gesture or grasping task caption. El-Flex/Ext elbow flexion/extension, FA-Pro/Sup forearm pronation/supination, Mov Time movement time, No of Vel Peak number of peak velocity, Sh-Abd/Add shoulder abduction/adduction, Sh-Flex/Ext shoulder flexion/extension, SPARC spectral arc length, TrunkDisp trunk displacement, Wr-Flex/Ext wrist flexion/extension. B Kinematic metrics during reaching proximally per task across subjects (N = 31). The metric expressions are presented in boxplots per task. The vertical black line in each subplot separates the grasp movement tasks on the left side and gesture movement tasks on the right side. Statistically significant comparable metrics across tasks are indicated by asterisks and the bold notation of the gesture or grasping task caption. El-Flex/Ext elbow flexion/extension, FA-Pro/Sup forearm pronation/supination, Mov Time movement time, No of Vel Peak number of peak velocity, Sh-Abd/Add shoulder abduction/adduction, Sh-Flex/Ext shoulder flexion/extension, SPARC spectral arc length, TrunkDisp trunk displacement, Wr-Flex/Ext wrist flexion/extension
