Review: Child Development Flashcards
(44 cards)
What is the developmental sequence
- physiologic flexion
- prone/POE
- head control
- rolling
- crawling (commando crawling first)
- sitting
- kneeling/0.5 kneeling
- standing/walking
Developmental stages
- premature
- neonate: 0-4 weeks
- infant
- toddler
- child
- adolescent
- young adult
- adult
- throughtout the lifespean
Describe motor development and what can mold it?
- growth and development of preterm infants follows variable motor paths
- motor development is molded by complex psycho social-cultural factors in the biological background of preterm infants
- fetus newborn and young infant have general movements: movements with great complexity and variation in which all body parts are involved
quality of life in the womb can make you more susceptible to conditions
Developmental theories
Reflex theory
- the basis of movement is the summation of reflexes
- all movements are responding to the environment
- sensory information causes movement
What are some uses of reflex theory
- testing reflexes in adults and developmental or primitive reflexes in children
- PNF proprioceptive neuromuslcar facilitation is based of reflexes
Hierarchial theory
- Top down model
- higher levels of CNS control the lower levels
- CNS controls peripheral movements
- Brain controls the SC which controls the PNS
Uses of Hierarchial theory
- stages of motor control
- mobility
- stability
- dynamic postural control
- skill - Developmental sequence occurs prone to standing
- development occurs
- cephalo to caudal
- proximal to distal
- gross to fine control
- total body movements (one unity) to dissociated movements (EX: upper body and lower body can move independently)
Motor Program theory
- we have genetically-based internal programs for movement
- central pattern generators: internal systems that allow for movements such as walking (these are automatic and are not taught)
- learning patterns that transfer to many conditions
Dynamic systems theory
- motor control is the result of the interdependence (dependence of 2 or more things) of many internal and external systems
- motor behavior is the result of interaction between the individual, environment, and task
- EX: you will move differently when you are walking due to being late
Dynamic systems uses
- interaction between visual, vestibular, and proprioceptive systems for balance/movement
- changes in gait or movement with injury or illness
- task-oriented approach of rehab
Perceptive-action theory and ecological theory
- in order to move there is a goal such as hunger
- internal or external goal or stimulant
- there is an internal model which links perception and action
- how we move depends on the environment
Neural Maturation theory
- development
- pre-determined hierarchical system/pre-determined way to move
- control of reflexes leads to more refined movement
- spiral development: flexion/extension and symmetry/asymmetry
Cognitive behaviorism theory
- environment shapes motor and cognitive development
- stimulation from environment is necessary for development to occur
Neuronal group selection
- functional circuits of neuronal activities
- practice strengthens some connections and weakens others
- parallel and reciprocal connections unique to each individual
Embodied mind concept
- link between what we know and what our bodies can do
- action and perception are needed for brain development
- functional tasks are completed by selecting from available neuronal options
Systems Theory
- body is a system with multiple degrees of freedom
- hierarchical control of muscle synergies
- muscles work together for movements
Uncontrolled manifold hypothesis
- Use synergies to define a coordination pattern
- in any synergy there are multiple possibilities which will all result in some degree of accuracy
- practice helps to select the best combination of movements
- EX: how much each muscle will contract can affect the movement
Children with neurological damage will have
- a commond denominator of prolonged neonatal reflexes
- repetition of these reflexes seems to eventually inhibit them.
- parents can work with the infant by assisting with the repetition of persistance reflexes
What happens if the reflex is absent or abnormal in infants
- the may suggest significant neurological problems and is a symptom not a disorder
Where are the primitive reflexes controlled
- the brainstem
- lower level control
Primary reflex system vs secondary system
normal development
- the primary reflex system is inhibited or transformed in the 1st year of life and a secondary or postural reflex system emerges
- the secondary system forms the basis for later adult coordinated movement
What are potential factors that can cause retained primitive reflexes
- trauma during pregnancy, during and or after birth
- exposure to toxins, drugs, toacco in utero
- stroke in utero or infants
- caesarean section delivery
- premature birth
- prolonged jaundice
- problems with feeding within the first 6 months of life
- developmental motor delays
- minimal floor time as an infant
Signs of retained primitive reflexes
see these = test reflexes
- w-sit: key sign for hypotonia/retained primitive reflexes
- bedwetting after age 5
- sensory overload
- visual tracking issues: sign = ball coming toard them and they cannot get the ball
- poor attention and focus
- trouble with emotional regulation
What are the symptoms of retained primitive reflexes
- anxiety
- motion sickness
- clumsy
- poor hand-eye coordination
- poor right/left discriminiation after the age of 8
- challenges with reading at age level
- poor handwriting at age level
- low muscle tone
- diagnosis of autism
- early diagnosis of ADHD
- decreased coordination with sporting activites
- challenges ith sequencing
- w-sitting and toe walking
- challenges sitting still
- bedwetting past age 7
- poor short-term memory
- hypersensitivity to sound, touch, movement
- speech and articulation challenges
- picky eating and/or oral motor challenges
- challenges with fine motor tasks at age level
