Impact of prior errors on visuomotor adaptation and savings: experimental considerations and clinical implications.

The motor system retains learning from visuomotor adaptation tasks in the form of "savings" to enable faster readaptation to similar perturbations in the future. Leow et al. (J Neurophysiol 116: 1603-1614, 2016) suggest that the experience of prior errors during relearning is necessary for savings while repetition of prior actions may not be sufficient. These findings provide novel insight into factors that contribute to visuomotor adaptation and can be applied to future experimental and clinical research.
