L2: Normal Development (see milestones FC's!!!) Flashcards
Sequence of Development
Planes
Sagittal→ Frontal→ Transverse
Typical Development
Flexion/Extension Relationship
Physiological flexion/Active flexor tone
Physiological Flexion/Active flexor tone
What is tight?
EXTs are tight first bc already elongated from physio. flexion
Development of flexion/extension control leads to _________
Postural control
Co-activation= midline
Sequence & Development of Muscle Activation and Use
Progression of mvmt abilities w/ maturation
6:
- Random mvmts
- Asymmetric Mvmts
- B/L Symmetrical Mvmts
- Alternating Mvmts
- Lateral Flexion
- Rotation
Sequence & Development of Muscle Activation and Use
Progression of mvmt abilities w/ maturation
Asymmetrical Mvmts age?
2-3mos
Sequence & Development of Muscle Activation and Use
Progression of mvmt abilities w/ maturation
B/L Symmetrical Mvmts age and what is crucial skill here?
3-5mos old
Midline is crucial skill
Sequence & Development of Muscle Activation and Use
Progression of mvmt abilities w/ maturation
Alternating mvmts→ still only have what planes of motion here?
Flexion/Ext
Sequence & Development of Muscle Activation and Use
Progression of mvmt abilities w/ maturation
Lateral Flexion→ how is this achieved?
Co-activation flex/ext for midline
*Sagittal plane mvmts coming together to form frontal plane mvmt
Sequence & Development of Muscle Activation and Use
Progression of mvmt abilities w/ maturation
Lateral Flexion
Rolling when?
4-5mos
Sequence & Development of Muscle Activation and Use
Progression of mvmt abilities w/ maturation
Lateral Flexion
Lateral SB to completion what age?
6mos
Sequence & Development of Muscle Activation and Use
Progression of mvmt abilities w/ maturation
Rotation→ combo of what planes?
Combo of sagittal and frontal planes
TRIcycle @ age?
3!!
Tri=3yo ****
SLS emergence @ age
2
Sensory Systems and Mvmt involves what?
Tactile/kinesthetic, Vision, Smell, Lvl of arousal and emotion
Nervous System:
Experience expectant/dependent on neural maturation
Repetition
Practice play! => Motor development and motor learning
Development Sequence as a guide:
- MANY variations in motor milestones development can occur in typ. development
- Motor milestones are part of a sequence leading to a skill
Development Sequence as a Guide:
Variations in motor milestone development
All of these can lead to deviations in “Normal”
- Asymmetry
- Excessive recruitment of isolated motor plan
- Lack of variety
- Inability to motor plan
- Preferences
- Lack of attention
Summary of Typical Development
- 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
