Feasibility and Usability of a Virtual Reality System

Condition(s) studied

Investigational drug(s) / intervention(s)

Rehabilitation with VRRS: The patients underwent an experimental intervention lasting two months (9 sessions lasting about 40 minutes) integrated into the regular activity of a semi-residential center for autistic adolescents and young adults. The proposed exercises were 2D and the patient interacted with the scenarios through the touch screen. For all participants, the tasks were the same, but difficulty and duration varied according to the needs and goals to be achieved.

Conventional cognitive training: Conventional cognitive training consisted of structured paper-and-pencil tasks and therapist-guided activities targeting multiple cognitive domains, including attention, visual-spatial processing, sustained attention, working memory, and problem-solving. These exercises were administered individually by a trained therapist and tailored to each participant's functional level. The intervention lasting two months (9 sessions, lasting about 40 minutes) integrated into regular activity of semi-residential center for autistic adolescents and young adults.

Study summary

Intellectual disability (ID) and autism spectrum disorder (ASD) are often co-occurring neurodevelopmental disorders that require composite intervention. However, standardized rehabilitation programs presented several limitations due to behavioral problems and poor engagement in proposed activity. The Virtual Reality Rehabilitation System (VRRS) is a medical device is recognized as one of the most advanced systems to rehabilitate patients with motor, cognitive, linguistic and behavioral disorders. The use of VRRS offers the opportunity to adapting task parameters according to the patient's performance and the virtual system increases engagement and avoids boredom and frustration. the patients underwent a two months experimental intervention integrated into the regular activity of a semi-residential center for autistic adolescents and young adults.

Eligibility

Primary outcome measure(s)

• Usability questionnaire — T0 (BASELINE) - T1 (SIX MONTHS)
  The questionnaire used a 5-point ordinal scale, where 5 is the most favorable score and 1 is the least favorable score; the score 3 corresponds to "no opinion". The questionnaire will be completed by all therapists at the end of the treatment.
• Virtual Reality Rehabilitation System (VRRS) electromedical device parameters: screen attention time — T0 (BASELINE) -T1 (SIX MONTHS)
  During the execution of the exercise, the attention time maintained on the screen was recorded.
• Virtual Reality Rehabilitation System (VRRS) electromedical device parameters: the number of repetitions of the exercises. — T0 (BASELINE) -T1 (SIX MONTHS)
  During the execution of the exercise, the number of repetitions of the exercises was recorded
• Virtual Reality Rehabilitation System (VRRS) electromedical device parameters:global scores for exercise. — T0 (BASELINE) -T1 (SIX MONTHS)
  The total scores obtained were recorded during the execution of the exercise.
