Handwriting capacity in children newly diagnosed with Attention Deficit Hyperactivity Disorder

Area of Science:

• Pediatric Neurology
• Developmental Psychology
• Occupational Therapy

Background:

• Preliminary evidence indicates potential handwriting difficulties in children with Attention Deficit Hyperactivity Disorder (ADHD).
• The precise nature of these handwriting challenges and their relationship to motor or behavioral issues requires further investigation.

Purpose of the Study:

• To characterize the handwriting abilities of children newly diagnosed with ADHD.
• To identify key predictors of handwriting performance in this population.

Main Methods:

• Evaluated 40 medication-naïve children with ADHD (mean age 8.1 years).
• Utilized the Evaluation Tool of Children's Handwriting-Manuscript, Movement Assessment Battery for Children (M-ABC), Developmental Test of Visual Motor Integration (VMI), and Conner Global Index.
• Assessed manual dexterity, visual-motor integration, and overall behavioral functioning.

Main Results:

• A significant majority (85.0%) of children exhibited manual dexterity difficulties.
• Handwriting performance, including speed and legibility, was highly variable.
• Visual-motor integration (VMI) emerged as the strongest predictor of legibility.
• Upper extremity coordination, specifically M-ABC ball skills, also correlated with word legibility.

Conclusions:

• Poor handwriting legibility and slow writing speed are prevalent in newly diagnosed ADHD.
• Motor abilities, including visual-motor integration and upper extremity coordination, are significantly associated with handwriting performance.
• Further research is necessary to explore the efficacy of interventions, such as stimulant medications, on improving handwriting and related motor functions.
