VR distraction had effects not only on immediate experiences but also upon the vividness of memories after the dental experience had ended.
Participants with higher dental anxiety showed a greater reduction in memory vividness than lower dental-anxiety participants.
“This study thus suggests that VR distractions can be considered as a relevant intervention for cycles of care in which people’s previous experiences affect their behavior for future events.”

Paired t tests revealed that VAS scores were significantly lower during VR compared with the movie (P < .001) and control (P < .001) conditions.
Similarly, blood pressure and pulse rate were lowest during VR, followed by the movie and control conditions.
Patients reported that they preferred the VR condition.

Areas covered include stroke rehabilitation (upper and lower extremity training, spatial and perceptual-motor training), acquired brain injury, Parkinson’s disease, orthopedic rehabilitation, balance training, wheelchair mobility and functional activities of daily living training, and the newly developing field of telerehabilitation. Four major findings emerge from these studies:
(1) people with disabilities appear capable of motor learning within virtual environments;
(2) movements learned by people with disabilities in VR transfer to real world equivalent motor tasks in most cases, and in some cases even generalize to other untrained tasks;
(3) in the few studies (n = 5) that have compared motor learning in real versus virtual environments, some advantage for VR training has been found in all cases; and
(4) no occurrences of cybersickness in impaired populations have been reported to date in experiments where VR has been used to train motor abilities.
