Nevertheless, the critical
questions that need to be answered before investing in
expensive equipment concern whether motor learning in
a virtual environment generalizes to the real world and
whether there are advantages of practice in a virtual
versus a real environment. There is affirmative evidence
for both questions in patients with chronic stroke, trained
on VR tasks for the hand [57] and arm [58]. Although
these studies are small and have not included controls,
they highlight the potential of an approach that emphasizes
principles of motor learning and then amplifies them
in the VR environment.
