goal of this research is to extend robotic therapy to wrist rotations using a
novel, 3-degree-of-freedom robotic therapy device for the wrist. This robot
is capable of tracking, guiding, and perturbing a personís wrist rotations
while he/she performs a set of virtual tasks. The first stage of this project
consists of establishing a quantitative foundation of wrist motion in
unimpaired subjects by examining stereotypical kinematic patterns,
coordinative strategies, and the effect of random disturbances. With this
foundation, we will test whether (and how) a program of robotic wrist
rotation training benefits stroke victims.
