The present research examined whether kinesthetic training for persons with Huntington's disease (HD) leads to improved performance in more complex perceptual-motor tasks. One group of 11 persons with HD and another of 10 healthy persons performed in a horizontal linear positioning task, which required the ability to process kinesthetic information. The results indicated that persons with HD did experience a small deficiency in performance of kinesthetic tasks. The size of the deficit was about the same, regardless of whether the task required immediate perception or memory for kinesthetic information. The healthy group's performance in the kinesthetic training task increased significantly over practice trials, while performance in the HD group did not change as a result of practice. Transfer of training was not found in either group. There was, however, evidence that persons with HD can make significant improvements in finger dexterity through training.
