title: Kinesthetic coordination of a movement sequence in humans.
abstract: This experiment examined whether kinesthetic input could be used to coordinate a 'movement sequence', a series of sequentially executed joint rotations. In this experiment, human subjects extended the elbow at a constant velocity and opened the hand as the elbow passed through a predetermined angle, as in throwing. Subjects were able to open the hand at the prescribed elbow angle, even though they received no visual feedback and they could not predict when the elbow would reach this angle. The only remaining source of information about elbow angle was kinesthetic input. Being able to control the internal timing of our movement sequences with kinesthetic input may be important to the way we move.
