Q

What is the hierarchical model?

A
  • movement is controlled from the top down
  • cortex is the top
  • higher structures inhibit lower structures
  • Two components from notes: Stages of motor control and development of Postural Control

Q

What is the role of sensation in motor control?

A
  • vital for movement
  • stimulates a reflexive movements, early on known as reflexive motor response
  • cues motor behavior in reflex dominated infants
  • In adults: provides feedback accuracy for UE and LE movement

Q

Describe motor control

A
  • neurological and mechanical process
  • process includes motor, cognitive, and perceptual development
  • allows nervous system to solve a movement problem: what m’s to use, what order, and how quickly

Q

Describe reflexes in terms the hierarchical model?

A

-nervous system integrates reflexes, or less mature responses, into voluntary movement

16
Q

What body parts are involved in righting and equilibrium reactions and what do they do?

A
  • involve the head and trunk

- automatic response to movement of COG in relationship to BOS

17
Q

Describe protective reactions

A
  • Extremity movement
  • Response with rapid displacement of COG
  • individuals must be able to prop on extended arms to have protective reactions
18
Q

Describe equilibrium reactions

A
  • most advanced postural reaction
  • last to develop
  • incorporate head and trunk righting reactions
  • occur when body moves relative to surface or surface moves relative to body (ex: tilt board)
19
Q

At what anatomical level are balance reactions developed (hierarchical)?

A

Cortex- equilibrium
Righting reactions- midbrain
Postural Tonic Reflexes- Brain stem
Phasic primitive Reflexes- Spinal Cord

20
Q

What are the components of the systems model?**

A
  1. limits of stability
  2. Environmental adaptation
  3. Musculoskeletal System
  4. Predictive Central Set
  5. Motor Coordination
  6. Eye-Head Stabilization
  7. Sensory organization
21
Q

Describe the limit of stability

A
  • boundaries of the BOS in any given posture
  • greater BOS = greater boundaries for stability
  • lesser BOS = decreased boundaries for stability
  • cone of stability
22
Q

Describe environmental adaptation

A

-posture adapts to the environment in which movement takes place

23
Q

Describe eye-head stabilization

A
  • visual system (eye) provides info about enviro during movement and gait
  • Vestibular system coordinates with visual system so stable visual image of enviro sent to brain
24
Q

Describe musculoskeletal system component

A
  • works w/ neurological system to control posture and balance
  • processes vital sensory info to allow correct postural and motor response: to plan and execute response
  • provides mechanical structure for postural response and postural alignment
25
Q

Describe predictive central set

A

AKA: postural readiness

  • sensation and cognition used as anticipatory cues prior to movement to establish postural readiness
  • must be present to support movement
26
Q

Describe motor coordination

A

ability to sequence m. response in timely fashion in response to displacement of COM withing BOS
-Ex: postural sway in standing

27
Q

Describe Sensory organization

A

3 systems for posture and balance and therefore motor control: vestibular, visual, and somatosensory
