Combined Effects of Virtual Reality and Computer Game-Based Cognitive Therapy on the Development of Visual-Motor Integration in Children with Intellectual Disabilities: A Pilot Study.

PMID 34316294WHAT IT FOUND
Thirteen children with intellectual disabilities improved on motor skills and visual perception tests after combined VR and computer game therapy.
However, the specific visual-motor integration score showed no significant change. Do not assume this combination works for integration.
Key findings
01Children showed significant improvement in total standard scores and percentile ranks on the motor function assessment (BOT-2).
02Children showed significant improvement in general visual perception and motor-reduced visual perception scores on the DTVP-2.
03The specific visual-motor integration score on the DTVP-2 did not show a significant difference between pretest and posttest.

What it does not show
The study had a very small sample size of only thirteen participants. There was no control group, so improvements cannot be definitively attributed to the specific VR and computer game intervention rather than natural development or conventional therapy. The study was a pilot, designed to examine feasibility and changes rather than to prove efficacy. Psychological aspects of the children were not evaluated.
The easy way to misread this
Do not interpret the improvements in motor and visual perception scores as evidence that visual-motor integration improved. The specific visual-motor integration score showed no significant change, and the lack of a control group means other factors could explain the other gains.
