Developmentsal Sequences (OTH Exam)

Question 1

Three Phases of Development

Answer 1

1. Primitive
2. Transitional
3. Mature

Question 2

Primitive

Answer 2

Conception to several months after birth
Movement.Muscle Function
-Change positon of body segments but NOT body in space
Postural suport is w/in the boundaries of enviornment
Limited WB

Question 3

Transitional

Answer 3

A few months after birth through mature development
Modify primitive stratagies for mature function (increase WB)
Movement/Muscle FUnctions:
-use of postural fixation (frog leg position)

Question 4

Transition Continued (righting)

Answer 4

Righting reactions : support and protective (brought on by antigravity movement)
Use of righting reactions for maintaining new positions in space and to facilitate movement from one position to another.

Question 5

Transitional Movement

Answer 5

Postural control and movement
Baby develops and uses stratagies to allow movement in space (WB to weight shifting)
Bilateral and unilateral weight shift patterns

Question 6

Transitional Movement Continued

Answer 6

Expand muscle activation for coactivation to develop support for WB on extremities in new position (coactivation provides you stability & mobility)

Question 7

Mature

Answer 7

Blend mobility and stability functions
Emergence of equilibrium and midline stability.
Conteralateral weight shit
Child enters this phase as soon as they can independently: sit, creep. roll, walk
Use a high guard position

Question 8

In mature a Child can :

Answer 8

Maintain postures
Move within the position
Move around the environment in a desired position.
Child develops internal control and has an infinte variety or unique patterns.

Question 9

Primitive Creeping/Prone Progression

Answer 9

Protective head turning
Head lift/primitive support
Neck reaction used to stabalize head on shoulders

Question 10

Transitional Creeping/Prone Progression (WB)

Answer 10

Head control on elbows- weight is on forearms/elboes
Flexion blended w/ extension in head and control develops/
On hands : trunk moves away from supporting surface.
Prone on hands or extended elbows

Question 11

Transitioal Creeping/Prone Progression (pivoting)

Answer 11

Prone extension- FULL extension to prepare for upright.
Pivoting- adaptd neck, trunk, and hip extension from prone extension and combines these w/ flexion.
Crawling- trunk centered support w/ extremity mvnt.

Question 12

Mature Creeping/Prone Progression

Answer 12

Creeping- movement on hands and knees

Includes getting into and out of position

Question 13

Primitive Sitting/Supine Progression

Answer 13

Baby attempts to right head and trunk when placed and helps in stting.
Head lag in PTS
Head align in PTS: flexors activate as baby approaches vertical position
Midline holding in supine
Still asmetrical in supine

Question 14

Transitional Sitting/Supine Progression

Answer 14

PTS head in midline and forward of trunk
Hands to feet/Feet to mouth
Activates extremities in space and pelvis in posterior tilts.
Pelvic tilt: feet up
Bridging
Supported sitting: baby holds position w/ UE support on surface using scapular ADD

Question 15

Mature Sitting/Supine Progression

Answer 15

Various positions arms free; child can vary position and move into and out of position freely
Equalibrum reactions form
Should be able to assume and move into and out of iusing full rotation.

Question 16

Primitive Roling

Answer 16

Gravity assisted

Question 17

Transitional Rolling

Answer 17

Spontaneous rolling: promotes some of the first changes of position in space.
Prone to supin and supine to prone
Rolling is neck righting rolling: no segmentation of the trunk.
Deliberate rolling: baby participates move in initationg the rolling pattern.
Segmentation is evedent as is intention.

Question 18

Mature Rolling

Answer 18

Generally by 8-9 months of age.

Full rotation, initation and control in midranges.

Question 19

Primitive Standing/Walinking Progression

Answer 19

Primary standing- momentary WB and standing w/ support.

Primary walking is forerunner to reciprocal walking

Question 20

Transition Standing/Walking Progression (pull-to-stand)

Answer 20

Pull-to-stand (adaptation of pull to sit)
Bi laterall pull to stand - UE’s used to stabilize and lift so LEs can be positioned
Involves a bilaterall weight shit and pulling of the body upward over both legs.
Unilateral pull to stand- weight shit is unilateral so one leg can move to a flat footed position

Question 21

Tansitional Standing/Walking Progresion (standing/walking)

Answer 21

Supported standing: against objects of held w/ hands.
Supported walking- movement from supported standing.
Moving supported on objects is called crusing

Question 22

Mature Standing/Walking Progression

Answer 22

Squatting- lowering the body from standing first w/ support and then independently; used in play.
Standing- 1st w/ a wide base and scapular ADD
Walking- experience in walking refines the pattern. Rotation allows the contralateral weight shift to emerge.
