Abstract
BACKGROUND
Evidences suggest that cognitive training facilitates cognitive function, and most studies have targeted adults and children older than 4 years of age. This study investigated the applicability and efficacy of a tablet computer-based cognitive training program for young children with cognitive impairment of cognitive age between 18 and 36 months.
METHODS
Thirty-eight children were randomly assigned to the intervention (n = 20, administered a tablet computer-based cognitive training program, for 30 minutes per session and twice a week over a period of 12 weeks) and control (n = 18, received the traditional rehabilitation program) groups. Mental scale of Bayley Scales of Infant Development II (BSID II), Pediatric Evaluation of Disability Inventory (PEDI), interest/persistence domain of the Laboratory Temperament Assessment Battery (LAP-TAB), Early Childhood Behavior Questionnaire (ECBQ), and Goal Attainment Scale (GAS) were evaluated before and after 12 weeks of therapeutic intervention.
RESULTS
The tablet computer-based cognitive training program was applicable to all children in the intervention group without any problems including irritable behavior or obsession about a tablet computer. After 12 weeks, Mental scale of BSID II, PEDI (social function), LAB-TAB (observation), LAB-TAB (manipulation), and GAS showed statistically significant improvements in the intervention group, compared with the values in the control group (P < .05). After adjusting for the pre-treatment measurements and cognitive age, the tablet computer-based cognitive training program had significant effect on the post-treatment measurements of Mental scale of BSID II, PEDI (social function), LAB-TAB (observation), LAB-TAB (manipulation), and GAS (P < .05). There was no association between the change in the scores and the severity of cognitive delay in the most of the measurements, however, the self-care domain of PEDI showed a negative association with the severity of the cognitive delay (r = -0.462, P = .04).
CONCLUSIONS
Application of a tablet computer-based cognitive training program was feasible and showed improvements in cognitive function in young children with cognitive impairment of cognitive age between 18 and 36 months, regardless of the severity of the cognitive delay. But severe cognitive delay can be related with less improvement in the self-care domain of PEDI.
