Postural Reactions

Question 1

newborn sensation

Answer 1

Cues reflexive movements

Question 2

childhood+ sensation

Answer 2

Guides volitional movements & postural reactions

Question 3

sensation

Answer 3

Visual
Auditory
Somatosensory
-Touch
-Temperature
-Proprioception
-Nociception
Vestibular

Question 4

POSTURAL REACTIONS

Answer 4

Help humans maintain posture in a changing environment
-Righting
-Protective
-Equilibrium
Postural reactions do not integrate. They evolve and mature. Ability to coordinate mobility and stability

Question 5

mobility =

Answer 5

movement

Question 6

stability =

Answer 6

posture against gravity

Question 7

mobility and stability

Answer 7

1. Uncontrolled mobility
2. Stability develops
3. Volitional, skilled mobility develops
   eg. infant kicking

Question 8

controlled, skilled movements are a combination of

Answer 8

mobility and stability

Question 9

LATERAL HEAD or

LABRYNTHINE RIGHTING

Answer 9

• Maintain or restore alignment of head or trunk in space
• Vestibular input to orient the head
• In any direction
• Without vision

Question 10

OPTICAL RIGHTING

Answer 10

Visual input to orient the head

Question 11

NECK ON BODY RIGHTING

Answer 11

• Maintain or restore alignment of body segments in relation to each other
• Log roll, no dissociation
• Proprioceptive and tactile input to orient the head
• eyes on horizon
• birth-4mo (neonatal)

Question 12

BODY ON BODY RIGHTING

Answer 12

Starts at legs & hips
-Segmental roll

PTs utilize

• Practice rolling
• Core & neck strength

Question 13

LANDAU REACTION (TLR)

Answer 13

Combo of optical head righting, body righting & labyrinthine righting

Assess & strengthen extensors

3 mo. to 1-2 years

also a postural reaction

Question 14

a baby should have head control at

Answer 14

4 months (red flag marker)

Question 15

EQUILIBRIUM REACTIONS

Answer 15

Total body response 
-Slow shift of COG outside base of support
Automatic
More sophisticated than righting reactions
Relies on sensory stimuli
-Vestibular
-Proprioception
-Visual

Question 16

LATERAL SITTING EQUILIBRIUM REACTION

Answer 16

Head and trunk righting

Arm and leg abduct opposite the weight shift

Followed by head and trunk rotation toward the abducted extremities

Question 17

equilibrium reaction progresses and persists

Answer 17

Prone: 6 months 
Supine: 7-8 mo
Sitting: 7-8 mo
Quadruped: 9-12 mo 
Standing: 12-24 mo
Occurs after basic stability in that position is attained
Persists
way to practice falling safely

Question 18

equilibrium reactions regress due to

Answer 18

poor strength

decreased ROM

Question 19

equilibrium reactions that are not present or ineffective result in

Answer 19

higher fall risk

unable to right self

Question 20

PROTECTIVE REACTIONS (parachute response)

Answer 20

Extremity response
to a quick displacement
of COG outside base of support

**when equilibrium reaction
is inadequate

Question 21

upper extremity protective extension in sitting

Answer 21

Forward: 6-7 mo
Sideways: 7-8 mo
Backward: 9-10 mo

Question 22

STEPPING or STAGGERING RESPONSE

Answer 22

forward step
