L2: Normal Development (see milestones FC's!!!)

Question 1

Sequence of Development

Planes

Answer 1

Sagittal→ Frontal→ Transverse

Question 2

Typical Development

Flexion/Extension Relationship

Answer 2

Physiological flexion/Active flexor tone

Question 3

Physiological Flexion/Active flexor tone

What is tight?

Answer 3

EXTs are tight first bc already elongated from physio. flexion

Question 4

Development of flexion/extension control leads to _________

Answer 4

Postural control

Co-activation= midline

Question 5

Sequence & Development of Muscle Activation and Use

Progression of mvmt abilities w/ maturation

6:

Answer 5

1. Random mvmts
2. Asymmetric Mvmts
3. B/L Symmetrical Mvmts
4. Alternating Mvmts
5. Lateral Flexion
6. Rotation

Question 6

Sequence & Development of Muscle Activation and Use

Progression of mvmt abilities w/ maturation

Asymmetrical Mvmts age?

Answer 6

2-3mos

Question 7

Sequence & Development of Muscle Activation and Use

Progression of mvmt abilities w/ maturation

B/L Symmetrical Mvmts age and what is crucial skill here?

Answer 7

3-5mos old

Midline is crucial skill

Question 8

Sequence & Development of Muscle Activation and Use

Progression of mvmt abilities w/ maturation

Alternating mvmts→ still only have what planes of motion here?

Answer 8

Flexion/Ext

Question 9

Sequence & Development of Muscle Activation and Use

Progression of mvmt abilities w/ maturation

Lateral Flexion→ how is this achieved?

Answer 9

Co-activation flex/ext for midline

*Sagittal plane mvmts coming together to form frontal plane mvmt

Question 10

Sequence & Development of Muscle Activation and Use

Progression of mvmt abilities w/ maturation

Lateral Flexion

Rolling when?

Answer 10

4-5mos

Question 11

Sequence & Development of Muscle Activation and Use

Progression of mvmt abilities w/ maturation

Lateral Flexion

Lateral SB to completion what age?

Answer 11

6mos

Question 12

Sequence & Development of Muscle Activation and Use

Progression of mvmt abilities w/ maturation

Rotation→ combo of what planes?

Answer 12

Combo of sagittal and frontal planes

Question 13

TRIcycle @ age?

Answer 13

3!!

Tri=3yo ****

Question 14

SLS emergence @ age

Answer 14

2

Question 15

Sensory Systems and Mvmt involves what?

Answer 15

Tactile/kinesthetic, Vision, Smell, Lvl of arousal and emotion

Question 16

Nervous System:

Answer 16

Experience expectant/dependent on neural maturation

Question 17

Repetition

Answer 17

Practice play! => Motor development and motor learning

Question 18

Development Sequence as a guide:

Answer 18

• MANY variations in motor milestones development can occur in typ. development
• Motor milestones are part of a sequence leading to a skill

Question 19

Development Sequence as a Guide:

Variations in motor milestone development

All of these can lead to deviations in “Normal”

Answer 19

• Asymmetry
• Excessive recruitment of isolated motor plan
• Lack of variety
• Inability to motor plan
• Preferences
• Lack of attention

Question 20

Summary of Typical Development

Answer 20

• Development is NOT linear!
• Dynamic Systems Approach:
  
  • Motor skills are result of many systems interacting/working together**
  • Development overlapping where skills may emerge while others remain constant or regress
• Mvmt promotes cognitive and perceptual development and go hand and hand to foster functional performance
