Abstract

The present study was conducted with the aim of investigating the effect of bilateral coordination exercises on the motor skills of children with developmental coordination disorder (DCD). The study population of this research were children aged ۶ to ۱۱ working in elementary school (۱st and ۲nd period) of primary schools in Islamshahr city in the academic year of ۱۴۰۱-۲. Three elementary schools for girls and three elementary schools for boys were randomly selected, and through the distribution and completion of the Developmental Coordination Disorder questionnaire, ۹۰ samples were identified in the study, and from all of them, Raven's IQ test and Bronincz Ozertsky's motor skills pre-test were taken. Then the experimental groups were divided into During ۶۰ days, in ۱۶ ۴۵-minute training and training sessions, they performed bilateral coordination exercises based on the Johnston and Ramon model. After performing the post-test of Bronincz-Ozertsky's motor skills, data analysis based on Kolmogorov-Smirnov, Shapiro-Wilk tests and analysis of covariance using    version ۲۶ software with a significant level (P?۰.۰۵) showed that performing bilateral coordination exercises It has a significant effect on balance components, bilateral coordination, upper limb coordination, response speed, motor vision control, and upper limb speed and agility. Also, performing a course of bilateral coordination exercises has no significant effect on the components of running speed, agility and strength.

Conclusion: performing bilateral coordination exercises can have a significant effect on improving and improving motor skills of children with developmental coordination disorder.
