Performance consistency in various motor assessments performed by children with Developmental Coordination Disorder

INTRODUCTION
PURPOSE
• Children with Developmental Coordination Disorder (DCD) have low motor skills that include marked delays in achieving motor milestones, poor balance, low coordination and handwriting difficulties.
• Because of the heterogeneous nature of this condition and its comorbidity with other disorders, it is difficult to develop a single profile of motor skill deficiencies in children with DCD and it remains unclear how a particular child with DCD may perform in an array of motor assessment batteries.
• The purpose of our experiment was to compare performance of children diagnosed with DCD through the use of three different assessments of motor skills.
• Bruininks-Oserestsky Test of Motor Proficiency – 2nd ed. (BOT-2):1. Fine manual control (FMC): • Fine motor precision - 7 items • Fine motor integration - 8 items
2. Manual coordination (MC):• Manual dexterity - 5 items • Upper-limb coordination - 7 items
3. Body coordination (BC):• Bilateral coordination - 7 items • Balance - 9 items
4. Strength and agility (SA):• Running speed and agility - 5 items • Strength - 5 items
All composites are combined resulting in a total motor composite (TMC) score providing a general measure of motor ability.
• Test of Gross Motor Development – 2nd ed. (TGMD-2):• Locomotor (LM) - run, gallop, hop, leap,
horizontal jump, slide• Object Control (OC) - striking a stationary
ball, stationary dribble, catch, kick, overhand throw, underhand roll
• Beery-Buktenica Developmental Test of Visual-Motor Integration – 6th ed. (Beery-VMI –6):• Visual Motor Integration (VMI) - 30 Items• Visual Perception (VP) - 30 Items• Motor Coordination (MC) - 30 Items
METHODS RESULTS
CONCLUSION
• In general, the results suggest that low performance across an array of motor assessments is consistent in children with Developmental Coordination Disorder, regardless of the type of the assessment.
• Comorbid behavioral and emotional issues pervading the disorder causes difficulties assigning a singular profile of motor skill deficiencies to a child diagnosed with DCD. However, consistent low performance in multiple motor assessments can provide a pathway to understanding additional similarities within the disorder.
• Further studies are necessary to explore detection and consistency of motor difficulties in children with DCD.

RESULTS
METHODS
• 4 participants (3 males, 1 female), all children 7 years of age.
• DCD diagnosis involved parent referral and was confirmed with screening tests:• Kaufmann Brief Intelligence Test – 2nd ed.
(KBIT-2) – 2 average, 1 above average, 1 upper extreme
• Movement Assessment Battery for Children – 2nd ed. (MABC-2) – all below the 2nd percentile
• All children were assessed with the BOT-2, TGMD-2, and Beery-VMI-6. The order of the assessments was counterbalanced.

• The comprehensiveness of the BOT-2 showed each child’s unique strengths and weaknesses. Of all tests, children had the most difficulties with the TGMD-2, demonstrating that gross motor skill performance, though not part of the DCD diagnosis, is a good indicator of motor difficulties. VMI scores confirmed the specific difficulties with manual coordination, as children did not have problems with the visual perception scale
