Insights

Motor problems are prevalent in children with attention deficit hyperactivity disorder (ADHD), with up to one-third potentially experiencing developmental coordination disorder. This highlights a significant issue needing attention in local healthcare services.

Area of Science:

  • Pediatric Neurology
  • Developmental Psychology
  • Child Psychiatry

Background:

  • Motor problems are frequently observed in children with attention deficit hyperactivity disorder (ADHD), but local prevalence data were lacking.
  • Understanding the extent of these motor issues is crucial for effective healthcare service planning.

Purpose of the Study:

  • To determine the prevalence of motor problems in children diagnosed with ADHD within a specific local population.

Main Methods:

  • A descriptive cross-sectional study was conducted involving children aged 6-9 years diagnosed with ADHD.
  • Data were collected over six months (July-December 2011) from a Hong Kong-based ADHD program.
  • The Movement Assessment Battery for Children and the Developmental Coordination Disorder Questionnaire-Chinese version were utilized to identify motor problems.

Main Results:

  • Analysis included data from 95 participants.
  • 63 children had no motor problems, 15 had borderline issues, and 17 had definite motor problems.
  • An estimated one-third of local children with ADHD may have developmental coordination disorder.

Conclusions:

  • Motor problems are common among local children with ADHD, with prevalence rates comparable to international findings.
  • The significant magnitude of motor problems in this population should not be underestimated.
  • Further attention to these issues is warranted despite study limitations.
