Numerous studies of motor learning have examined the adaptation of hand trajectories and grip forces when moving grasped objects with novel dynamics. Such objects initially result in both kinematic and kinetic errors; i.e., mismatches between predicted and actual trajectories and between predicted and actual load forces. Here we investigated the contribution of these errors to both trajectory a...

When estimating preinjury grip strengthfor compensation and rehabilitation purposes, two methods have been identified in the literature: (a) comparison with the unaffected hand and (b) reference to grip strength normative data. The literature is divided about whether a significant difference exists between the grip strengths of a person's two healthy hands. Some researchers argue that handednes...
