Week 11 (12) Flashcards
What is attention deficit Hyperactivity disorder?
disorder that affects attention span, concentration, and how impulsive and active the person is
What is the prevalence of ADHD?
1-13% Canadian children and youth. Boys 3-4x more likely to be diagnosed than girls
What are the causes and risk factors of ADHD?
- genetics
- brain injury
- teratogens
- premature birth
- low birth weight
What are the characteristics of ADHD?
- affects executive functioning: ability to organize and act on information, difficulty focusing
- challenges with fine and gross motor skills; slower and more variable reaction times
What are the intervention strategies of ADHD?
mixed exercise programs
- focus on coordination, planning and movement control
- can promote: fine motor precision, symptoms reduction, executive functioning
Examples: sensorimotor training, coordinative games, martial arts or swimming
What is autism spectrum disorder?
neurodevelopmental condition that can affect communicating with other, sensory processing and attentional focus
What is the prevalence of autism spectrum disorder?
2% of Canadian children and youth. Boys 4x more likely to be diagnosed than girls
What are the causes and risk factors of ASD?
- lesser known
- genetics
- premature birth
What are the characteristics of ASD?
- low motor ability compared to neurological peers
- difficulty with fine motor skills and gross motor skills
development: - motor skills are connected to communication development
- motor skill delays may worsen or become more apparent over time
What are the intervention strategies for ASD?
- encourage early diagnosis (use standardized assessments)
- proactive motor skill monitoring
- early, targeted interventions
- combine motor and communication goals
What is cerebral palsy?
a group of chronic disorder affecting body movements and muscle coordination
What is the prevalence of cerebral palsy?
Most common physical disability in childhood. Diagnosed in 2-2.5 children per year
What are the causes and risk factors of cerebral palsy?
- premature birth
- lack of blood and oxygen
- brain injury
- brain infection
What are the motor types of cerebral palsy?
spastic: most common; muscles appear stiff and tight; arises from otor cortex damage
dyskinetic: characterized by involuntary movements; arises from basal ganglia damage
ataxic: characterized by shaky movements; affects balance and sense of positioning in space; arises from cerebellum damage
mixed types: combination damage
What are the motor challenges of cerebral palsy?
- affects one or many limbs
- controlling balance
- gross motor functions
- motor planning
- bimanual tasks
- motor sequencing
What are the intervention strategies for cerebral palsy?
- identify and intervene early
- features: child-initiated movement, task-specific training, environmental enrichment and parental coaching
What is developmental coordination disorder?
dyspraxia
condition of poor coordination and clumsiness
not any known disorder, disease, disability
What is the prevalence of DCD?
5-6% of children. Higher in males than females
What are the causes and risk factors of DCD?
- pre-term birth
- common co-occurrence with ADHD, ASD, other learning disabilities
What are the intervention strategies for DCD?
- early intervention is promising
- involving parents and teachers
- task-oriented intervention are most effective
→ direct, repetitive practice of meaningful tasks
→ occupational and physical therapy should focus on tasks across fine and gross motor skills
What is the prevalence of down syndrome?
1 in 750 births
What are the causes and risk factors of down syndrome?
- extra chromosome
- advanced maternal age
What are the motor characteristics of down syndrome?
- gross motor skills
- delayed walking onset
- postural control
- fine motor skills
- more time to learn movements
What are the intervention strategies of down syndrome?
- frequent practice over long sessions, early and throughout development
- dual tasks (target both motor and executive function)
- adaptive sports and activities
