Development Progression 0 - 6 Months

Question 1

Prone 0 - 1 Mo (4)

Answer 1

1. Turns Head side to side.
2. Lifts head up momentarily.
3. LE’s flexed. pelvis is high off the supporting surface.
4. UE’s ADD and flexed.

Question 2

Supine 0-1 Mo (5)

Answer 2

1. Head held to one side.
2. Flexed and asymmetrical
3. UE’s : flexed and ADD
4. LE’s : flexed, ADD, and ER
5. Extremities move around without purpose.

Question 3

Prone 2 Mo (5)

Answer 3

1. Lifts head slightly off support surface (45 degrees)
2. UE’s increased ER and ABD
3. Able to bare weight on forearms.
4. Elbows are behind sh.
5. LE’s - decreased hib Flex so pelvis is lower to support surface. (increased hip ext.)

Question 4

Supine 2 Mo (4)

Answer 4

1. Head-increase rotation to the side, rarely in midline
2. Increased ATNR repsponse
3. UE’s increased sh. ABD and elbow ext.
4. LE’s increased ER and ADD : feet on surface.

Question 5

Prone 3 Mo (4)

Answer 5

1. Increased extension in head, neck, and uppoer trunk during heas lifting and turning.
2. head is not lifted to about 90 degrees AND CAN ROTATE FREELY.
3. .UE’s: HZ ABD & ADD = FOREARM WB, chest elevation, elbows are now in line with sh. ER
4. LE’s : lumbar extension, pelvis is down on the support surface. (hips still flex, ABD, and ER)

Question 6

Supine 3 Mo (5)

Answer 6

1. Increased symmetry
2. CAN HOLD HEAD IN MIDLINE
3. UE’s Antigravity flex and IR (can lift and hold hands which increase exploration)
4. Arms come together at chest.
5. LE’s: “frog legged” increased ER, ABD, feet together.

Question 7

Prone 4 Mo (5)

Answer 7

1. Increased extensor control.
2. Head is in midline & Rotating
3. Chest lifted off support surface
4. UE’s: HZ ADD of Sh. to help lift up the chest. FOREARM WB.
5. LE: increase lumbar ext: anterior pelvic tilt. HIPS ARE DOWN.

Question 8

Supine 4 Mo (5)

Answer 8

1. Increased control of flexors to balance strong extensors.
2. “Gathers self together” - hands to knees
3. UE’s : hands together in space (sh. flex) Hands, eyes to knees (starts reaching for feet)
4. LE’s : increased hip extension, increased anterior pelvic tilt; some abdominal control developing, random pushing with LE’s.
5. ROLLS SIDE TO SIDE: from the “collected position” of hands to knees using neck righting by hyper-flexing neck.

Question 9

Prone 5 Mo (5+)

Answer 9

1. Increased ext. in low back and hips.
2. Extended arm WB
3. Chest is elevated
4. FOREARM WEIGHT SHIFT, sh. control, upper trunk weight shift and rotation, lateral body righting, ABILITY TO REACH, propioception into sh, forearms, and hands.
5. Landau

Question 10

Supine 5 Mo (5)

Answer 10

1. Body starts to move in seperate segments
2. Increased flexor control against gravity
3. Feet to mouth (now elongates extensor muscles)
4. ROLLS FROM SUPINE TO SIDELYING w/ LE DISSOCIATION: head laterally rights, bottom leg bears weight; muscles are elongated, top leg is laterally flexed against gravity.

Question 11

Prone 6 Mo (6)

Answer 11

1. WB on extended arms
2. Hip extension
3. Strong extension: pushes backward secondary to scapular mobility.
4. WEIGHT SHIFT on extend arms
5. Forearm weight shifting
6. EQUILIBRIUM REACTIONS

Question 12

Supine 6 Mo (5)

Answer 12

1. LIFTS HEAD Ily
2. Hands yo feet (midrange control in space)
3. Extended arms (reaches for mom)
4. REACHES FOR TOYS (1 or 2 hands; transfers objects)
5. ROLLS SUPINE TO PRONE

Question 13

Sitting 1-0 Mo (3)

Answer 13

1. Pulled to sit (PTS) = No flexor control of head or trunk
2. Head flops forward
3. Back is round

Question 14

Sitting 4 Mo

Answer 14

Buring PTS the 4 mo has increased flexor control, increased symmetry, some abdominal activity, and some lower extremity flexion.

Question 15

Sitting 5 Mo (4)

Answer 15

1. PTS - no head lag, initates chin tucking, abdominals are active, LES flex at hips & knees
2. Increased head control
3. Increased back extnesion; leans forward at hips and not supine
4. UE’s support forward

Question 16

Sitting 6 Mo (4)

Answer 16

1. Lifts head independently
2. Pull’s w/ UE’s
3. LE’s - flex at hips and extend at knees
4. In the PTS test, the baby know takes the examine’s finger and pulls himself up while tucking his chin and flexing his legs.
