Unit I - Dyspraxia Flashcards
apraxia
impairment in the ability to accomplish previously learned and performed complex motor actions
developmental dyspraxia
failure to have ever acquired the ability to perform age appropriate complex motor actions
disorders of praxis (older taxonomy)
dyspraxia
bilateral integration and sequencing
somatodyspraxia
bilateral integration and sequencing (BIS)
a type of dyspraxia in which there is evidence of deficits in vestibular and proprioceptive processing.
o For deficits in BIS to be considered sensory integrative in nature, they must be accompanied by evidence of poor sensory processing (generally vestibular proprioceptive sensations)
o Mild form of praxis disorder
o Problems with coordinated use of 2 sides of the body
o Deficits in performing sequences of movement
o Daily tasks
Confusion of right-left
Poor lateralization of hand function (no hand dominance)
Avoidance of midline crossing
Poor ability to skip, do jumping jacks or stride jumps, or catch and throw a ball
Handwriting deficits
Difficulty using scissors
somatodyspraxia
- more severe
*evidence of poor tactile processing, and may have deficits in vestibular and proprioceptive processing
o poor motor planning of both anticipatory, feed forward-dependent movements, and actions that depend of sensory feedback
o child has difficulty with planning the same kind of tasks problematic for children with BIS deficits as well as some additional, generally easier tasks.
o Daily tasks
Delays in acquisition of self-care skills
Poor organization
Difficulty manipulating and assembling toys
Poor social relationships with siblings or playmates
clinical presentations of dyspraxia
behavioral issues, clumsiness, poor fine motor skills, delayed ADL skills, poor performance in timed tasks, poor self concept, decreased play repertoire, poor play skills
3 areas defined in praxis activities
- ideation
- planning
- execution
ideation
conceptualizing an action
• Likely a cortical function
• The prefrontal cortex is involved in the process
• Plays a major role in setting goals for complex, goal-directed sequences of movement, especially in novel situations
planning
- setting up the activity
• The premotor and supplementary motor areas play key roles in planning of movement.
• Involve translation of a movement strategy into action
• Proprioceptive input plays a key role in motor planning – sensation of movement (ie. speed, rate, sequencing, timing, and force) and joint position. Provides a child with a “map” of where the body is in relation to objects in the environment
execution
the ability to successfully complete and finish the task
• The primary motor cortex play a key role in motor execution and voluntary action
• Information from the primary motor cortex is transmitted to the muscles for execution via the corticospinal and corticobulbar pathways.
• The cerebellum also has a major role in execution of coordinated movement
• The basal ganglia is most important in completion of movement sequences
Dyspraxia in the pre-school child
- May not be able to run, hop or jump.
- History of delay reaching milestones e.g. rolling over, sitting, walking and speaking.
- Appears not to be able to learn anything instinctively but must be taught skills.
- Poor at dressing.
- Slow and hesitant in most actions.
- Poor pencil grip.
- Cannot do jigsaw or shape-sorting games.
- Art work is very immature.
- Has no understanding of in / on / behind / in front of etc.
- Unable to catch or kick a ball.
Dyspraxia in the school age child
- All the problems of the pre-school child may still be present with little or no improvement.
- PE is avoided. Coordination difficulties can be particularly problematic in physical education classes and other sports activities.
- Child does poorly in class (group) but significantly better on a one-to-one basis.
- Attention span is poor, and the child may react to stimuli without discrimination.
- May have trouble with math, copying from the blackboard.
- Writing is laborious and immature.
- Unable to remember and / or follow instruction.
- Generally, poorly organized.
- Commonly anxious and distractible.
- Child finds it difficult to keep friends or judge how to behave in play situations
- Difficulty doing fine-motor activities such as tying shoelaces or buttoning clothing
- Poor sense of direction
Teenagers & Adults
The challenges presented to adults with dyspraxia can be seen in all aspects of everyday life. Difficulties can have an impact on:
• Driving
• Completing household chores
• Cooking
• Personal grooming and self-help activities
• Manual dexterity needed for writing and typing
• Speech control - volume, pitch and articulation
• Perception inconsistencies - over- or under-sensitivity to light, touch, space, taste, smell.
Dyspraxia Goals:
Improve registration and integration of sensory input as it relates to the praxis deficit Increase awareness and strength in muscle synergies, develop mature postural control Develop adequate body scheme Increase complexity of play Enhance ideational skills Improve constructional skills Improve organization of behavior Improve sequencing and timing
Treatment Strategies May Include:
Progress from activities that require simple, discrete movements to those that require more complex movement sequences (ie. play on 1 piece of equipment then play on multiple pieces of equipment, grade up play on 1 piece of equipment).
Develop praxis in the context of play (tap into child’s inner drive)
Help child remember strategies that were successful, talk through ineffective strategies
Help child to slow down, think about plan before executing
