Ped Neuro Rehab Exam 2- Lecture Five (Dcd)

Front 1

What is developmental coordination disorder (DCD)?

Back 1

Motor coordination markedly below expected level for chronological age and intelligence level.

Significantly interferes with ADLs and/or academic achievement.

Not due to a medical condition
Doesn't meet criteria for PDD
If MR is present, motor difficulties are in excess of those typically associated with it.

Front 2

What is DCD a significant comorbidity with?

Back 2

learning disability and ADHD

Front 3

__% of the population display characteristics of DCD.

Back 3

6

Front 4

DCD Pathophysiology

Back 4

Prematurity
Deficit in efference copy signals.

Front 5

Control Based Learning Theory (COBALT)

Back 5

Hypothesizes environmental goal triggers activity in the dorsolateral frontal areas of the brain.

Frontal area sends signals to the posterior parietal lobe.

Intentions can be integrated with previous visual and kinesthetic perceptions.

Front 6

Parietal lobe

Back 6

connect the motor areas of the brain

Front 7

Supplemental motor cortex/basal ganglia

Back 7

Sequencing of actions and control parameters

Front 8

Primary motor cortex

Back 8

receives these inputs, sends efferent signals to the SC

Front 9

Prior to execution, efference copy of a motor action is sent...

Back 9

via corollary pathway to parietal lobe to be stored.

Front 10

Efference copy

Back 10

The CNS image created once the learner engages in new motor acts.

Assists in anticipating which motor control variables should be utilized in novel motor acts.

Feedforward bias- after prolonged practice indicates proficiency.

Front 11

Limitations of body structures and functions with DCD

Back 11

Reaction time
Visual-perceptual, visual-spatial, visual-motor impairment
Poor timing, rhythm, and force control.

Front 12

Difficulty:

Back 12

identifying important details, analyzing task to understand important components, using past experience, executing, and using feedback.

Front 13

Examples of activity limits with DCD

Back 13

messy eaters
Late walkers
Excessive frustration
Shoe tying/dressing difficulties
Poor handwriting

Front 14

When is DCD usually identified?

Back 14

Not usually identified in children younger than school age due to wider range of "normal" variation of motor skills

Older children may be looked over b/c they no longer engage in activities at which they have difficulty.

Discriminative/evaluative tools for DCD

Back 16

Front 17

Motor Assessment Battery for Children

Back 17

Ages 3-16

Motor domains: manual dexterity, aiming & catching, and balance

Checklist for teachers/parents
Program planning.

Front 18

Three intervention approaches for DCD

Back 18

Guided imagery, cognitive approaches, and task specific intervention

Front 19

Guided imagery

Back 19

Cognitive exercise used to imagine a motor action that isn't actually being performed.

Front 20

Cognitive approaches

Back 20

Goal, plan, do, check

Develop a goal, make a plan to achieve it, carry out the plan, evaluate the outcome.

Front 21

Task specific intervention

Back 21

Hypothesize why a task is difficult for the child.
Plan an intervention related to the hypothesis.
Use repeated practice in environments where the task occurs.

Front 22

MATCH

Back 22

Modify task
Alter expectations
Teach strategies
Change environment
Help by understanding
