Persistence of motor adaptation during constrained, multi-joint, arm movements.
We studied the stability of changes in motor performance associated with adaptation to a novel dynamic environment during goal-directed movements of the dominant arm. Eleven normal, human subjectsExpand

Impedance control and internal model formation when reaching in a randomly varying dynamical environment.
We investigated the effects of trial-to-trial, random variation in environmental forces on the motor adaptation of human subjects during reaching. Novel sequences of dynamic environments were appliedExpand

Haptic Guidance Can Enhance Motor Learning of a Steering Task
Haptic guidance can improve the immediate performance of a motor task by enforcing a desired pattern of kinematics, but several studies have found that it impairs motor learning. In this study, weExpand
