Brief Summary:
Developmental coordination disorder (DCD) affects 5-6% of the school-age population, equating to ~400,000 children, or 1-2 students in every Canadian classroom. Children with DCD find it hard to learn motor skills and perform everyday activities, such as getting dressed, tying shoelaces, using utensils, printing, riding a bicycle, or playing sports. Researchers and clinicians do not know what causes DCD or why children with DCD struggle to learn motor skills. Using MRI, this study will increase understanding of how the brain differs in children with/without DCD and determine if rehabilitation can change the brain and improve outcomes of children with the disorder.

Arm Intervention/treatment
Experimental: Treatment Arm
Participants are randomized to treatment group. After the first MRI scan, participants are assessed by an independent occupational therapist (before and after intervention) and participate in 10 treatment sessions with a treating occupational therapist. Following the post-treatment assessment, participants have a second MRI scan. Twelve weeks later, participants have a third, follow-up scan.
Behavioral: Cognitive Orientation to Occupational Performance (CO-OP)
CO-OP is a cognitive approach to solving functional motor problems (Polatajko et al., 2001b). Therapists teach children a global problem solving strategy (Goal-Plan-Do-Check) as a framework for developing specific strategies for overcoming motor problems; these strategies are determined after a dynamic performance analysis by the therapist to determine where the "breakdown" is in performing the task. Occupational therapists will see children once weekly for one hour over 10 weeks as per published protocol (Polatajko et al., 2001b), plus two assessment sessions. Children will select three functional motor goals to be addressed over the course of treatment, rating their performance and satisfaction of these goals pre- and post-intervention.

No Intervention: Waitlist control
Participants are randomized to the waitlist control group. After the first MRI scan, participants "wait" for 12 weeks and then have a 2nd MRI scan. Participants then have 10 treatment sessions with an occupational therapist and are assessed by an independent occupational therapist before and after treatment. Participants then have a third MRI scan to examine brain changes associated with intervention.

Primary Outcome Measures :
  1. Canadian Occupational Performance Measure [ Time Frame: 12 weeks ]
    Children will rate performance and satisfaction (10 point Likert scale) of their three motor goals

  2. diffusion tensor imaging [ Time Frame: 12 weeks ]
    fractional anisotropy and diffusivity (mean, axial, and radial)

Secondary Outcome Measures :
  1. Bruininks Osteretsky Test of Motor Proficiency [ Time Frame: 12 weeks ]
    standardized assessment of motor skills

  2. Performance Quality Rating Scale [ Time Frame: 12 weeks ]
    qualitative observations of movement quality

  3. functional connectivity [ Time Frame: 12 weeks ]
    spatial independent components analysis of resting state networks

  4. functional magnetic resonance imaging [ Time Frame: 12 weeks ]
    patterns of brain activation during mental rotation task

  5. morphometry [ Time Frame: 12 weeks ]
    white matter, cortical gray matter, deep gray matter, and total volumes for cerebrum and cerebellum
