The motor proficiency of 56 boys with attention deficit hyperactivity disorder (ADHD) was compared with that of 56 boys with learning disabilities (LD); both groups were divided into two age groups, 7 to 8 years and 9 to 12 years. Boys with ADHD were taking Ritalin and attending public schools. Boys with LD were medication-free and attending private schools for LD. The Bruininks-Oseretsky Test of Motor Proficiency–Long Form (BOTMP–LF) was used to measure balance, bilateral coordination, strength, upper limb coordination, response speed, visual-motor coordination, and upper limb speed and dexterity. MANOVA revealed significant main effects for condition and age. Subsequent univariate ANOVAs revealed (a) expected age differences on all but one item and (b) significantly poorer performance for boys with ADHD than boys with LD on all variables except balance, upper limb coordination, and response speed.
