Physical demand but not dexterity is associated with motor flexibility during rapid reaching in healthy young adults [PDF]

, 2015
Healthy humans are able to place light and heavy objects in small and large target locations with remarkable accuracy. Here we examine how dexterity demand and physical demand affect flexibility in joint coordination and end-effector kinematics when ...
