ABSTRACT

Objective: The purpose of this study was to examine the relationship between timing and motor function and between timing and executive function in children with Attention Deficit Hyperactivity Disorder(ADHD). Methods: The subjects were 32 children with ADHD aged between 6 and 12. The study tool used Interactive Metronome(IM) for the timing, Bruininks-Oseretsky Test of motor proficiency, Second edition(BOT-2) for the motor functions, and STROOP color and word test and Children’s Color Trails Test(CCTT) for the executive functions. A correlation analysis was conducted to analyze the relationship between timing and motor function and between timing and executive function. Results: Examining the correlation between the timing and the motor functions of the ADHD children, there was a negative correlation between the fine manual control and the body coordination of composite in the BOT-2 (p<.05). And there was a negative correlation between the fine motor precision and bilateral coordination of subtest in the BOT-2. Examining the correlation between the timing and the executive functions of the ADHD children, there was a negative correlation between the word score in the STROOP color and word test (p<.05), and CCTT-1 in the Children’s color trails test (p<.05). Conclusion: The results of this study confirmed the relationship between timing and motor function and between timing and executive function. Timing evaluation can predict the motor functions and executive functions of children with ADHD.
