Virtual Reality with Customized Positive Stimuli in a Cognitive-Motor Rehabilitation Task
Virtual Reality applications for integrated cognitive
and motor stroke rehabilitation show promise for providing more
comprehensive rehabilitation programs. However, we are still
missing evidence on its impact in comparison with standard
rehabilitation, particularly in patients with cognitive impairment.
Additionally, little is known on how specific stimuli in the virtual
environment affect task performance and its consequence on
recovery. Here we investigate the impact in stroke recovery of a
virtual cognitive-motor task customized with positive stimuli, in
comparison to standard rehabilitation. The positive stimuli were
images based on individual preferences, and self-selected music
(half of the sessions). 13 participants in the subacute stage of
stroke, with cognitive and motor deficits, were allocated to one of
two groups (VR, Control). Motor and cognitive outcomes were
assessed at end of treatment (4-6 weeks) and at a 4-week followup.
Both groups showed significant improvements over time in
functional ability during task performance, but without changes
in motor impairment. Cognitive outcomes were modest in both
groups. For participants in the VR group, the score in the task was
significantly higher in sessions with music. There were no
statistical differences between groups at end of treatment and
follow-up. The impact of VR therapy was lower than in similar
studies with stroke patients without cognitive deficits. This study
is a first step towards understanding how VR could be shaped to
address the particular needs of this population.

One of the significant benefits of Virtual Reality in Nursing Education is that it enables students to learn at their own pace and convenience. The customized learning experience allows students to focus on their individual learning needs, and the feedback provided by the simulation can help them to improve their skills and competence.
Overall, Virtual Reality In Nursing Education has the potential to transform the way nursing education is delivered. With the integration of this technology, nursing students can receive a more comprehensive and effective learning experience that can ultimately lead to better patient care and outcomes.
