The use of virtual environments is a new and fast-developing field in pediatric neurorehabilitation. The first longitudinal study in Estonia on the cognitive and social rehabilitation of children with acquired brain injury was completed at the University of Tartu, confirming the efficiency of using computer-based programs and virtual reality for improving children’s attention, visuospatial abilities and social skills.

According to a researcher at the University of Tartu Faculty of Medicine, Marianne Saard, neurorehabilitation is a systematic intervention designed to compensate for or remediate cognitive and/or behavioral impairments caused by brain injury, to improve resilience in daily life, increase skills to do what is desired and required, but which is difficult due to the impairments caused by the injuries.

In her doctoral thesis, “Modern Cognitive and Social Intervention Techniques in pediatric Neurorehabilitation for Children with Acquired Brain Injury,” Saard studied one of the most novel possibilities for pediatric neurorehabilitation available today: use of a computer-based environment and virtual reality. “It is a method that is engaging and safe for children, and allows them to practice the skills they need, from attention, space awareness and memory, to manual skills and to develop communication skills,” noted Saard.

The positive effect of neurorehabilitation in the treatment of cognitive and social deficits in children with acquired brain injuries has been proved by many earlier studies, and was also confirmed by the first longitudinal study in this field in Estonia conducted by Saard. Within the doctoral thesis and under the supervision of dr Anneli Kolk, an associate professor in pediatric neuropsychology at the University of Tartu, Saard and the research team developed research-based intervention protocols and new technology-based rehabilitation methods for the specific treatment of impaired functions in children.

The study involved 59 children with a diagnosis of epilepsy, traumatic brain injury or tic disorder and a control group of 47 healthy children, all aged eight to 13 years. The children in the study group completed 10 training sessions, and were tested before and after each of the sessions.

For the rehabilitation of attention and visuospatial impairments, intervention protocols were created based on the ForamenRehab computer program. A structured social rehabilitation model was developed for improving children’s social skills and to test the efficiency of the model, and a rehabilitation process was conducted in a virtual reality environment and on two multitouch tables: the Snowflake Multiteach Tabletop and the Diamond Touch Table.

“During 10 training sessions, children developed their cooperation skills by solving complex situations in a virtual environment and improved their social skills through analysis and role play,” described Saard.

The doctoral thesis confirmed the effectiveness of computer-based and virtual reality programs in the treatment of cognitive and social impairments. “After training, children’s performance significantly improved in two attention components—complex attention and tracking—and three spatial perception components: visual-constructive skills, visual attention and visuospatial perception. Furthermore, a follow-up assessment 1.3 years later showed the sustained, positive effect of the training. The social communication components were also significantly improved.”

According to Saard, feedback from the children and their parents showed that the skills acquired through training carried over to everyday life—children’s academic performance and behavior improved. “100% compliance indicated that children were motivated to participate in trainings and that computer-based rehabilitation is suitable for the treatment of children’s cognitive and social deficit,” confirmed Saard.

Marianne Saard defended her doctoral thesis, “Modern Cognitive and Social Intervention Techniques in pediatric Neurorehabilitation for Children with Acquired Brain Injury,” on 29 January 2020 at Ravila 19 Tartu.
