The Effect of Selected Cognitive Games on the Promotion and Stability of Executive Functions in Children With Developmental Coordination Disorders

Background and Aims: Children with developmental coordination disorders experience some form of impairment in some executive functions. The present study was designed and conducted to study the effect and retention of cognitive games on the development of three components of executive functions (response inhibition, working memory, and cognitive flexibility) among children with developmental coordination disorders. Methods: The present study was a quasi-experimental study with a control group. Thirty girls aged 7-10 years with developmental coordination disorder Based on the score obtained in the Movement Assessment Battery for Children-second edition (MABC-2) test set and based on the IQ score, were divided into two experimental and control groups. MABC-2 and Cattle and intelligence tests were used for initial screening, and N-Back, Stroop, and Go-NOGO tests measured working memory, cognitive flexibility, and response inhibition. The training protocol consisted of a series of purposeful cognitive and motor games that explicitly considered the development of a specific component of executive functions. Data were analyzed using a combined two-way analysis (2×3) of variance. Results: The findings showed, performance Working memory (P=0.0001) performance, cognitive flexibility (P=0.045), and response inhibition (P=0.010) increased in the experimental group from pretest to posttest, While no such change was observed in the control group. Also, the effect of improving games on working memory (P=0.0001) and response inhibition (P=0.033) was maintained until the retention test. At the same time, there was no significant difference between cognitive flexibility in the retention test of children with developmental coordination disorder in the experimental group and control. Conclusion: Based on the findings, cognitive-motor games effectively improve and maintain working memory, inhibit response, and develop cognitive flexibility. As a result, according to the results of this study and other studies, it can be acknowledged that intervention as a process as a process-oriented therapy with the involvement of the individual in a mental process improves the executive functions of children with developmental coordination disorder and games introduced in this Research is a good framework for designing and implementing high quality and reproducible programs.

Developmental coordination disorders and sensory processing and integration: Incidence, associations and co-morbidities

Introduction Children with developmental coordination disorder or sensory processing and integration difficulties face challenges to participation in daily living. To date there has been no exploration of the co-occurrence of developmental coordination disorders and sensory processing and integration difficulties. Method Records of children meeting Diagnostic and Statistical Manual – V criteria for developmental coordination disorder ( n = 93) age 5 to 12 years were examined. Data on motor skills (Movement Assessment Battery for Children – 2) and sensory processing and integration (Sensory Processing Measure) were interrogated. Results Of the total sample, 88% exhibited some or definite differences in sensory processing and integration. No apparent relationship was observed between motor coordination and sensory processing and integration. The full sample showed high rates of some difficulties in social participation, hearing, body awareness, balance and motion, and planning and ideation. Further, children with co-morbid autistic spectrum disorder showed high rates of difficulties with touch and vision. Conclusion Most, but not all, children with developmental coordination disorder presented with some difficulties in sensory processing and integration that impacted on their participation in everyday activities. Sensory processing and integration difficulties differed significantly between those with and without co-morbid autistic spectrum disorder.
