My developmental chart

Prone progression

Position / Skill	1 mo	2-3 mo	4-5 mo	6-7 mo	8-9 mo	9-10 mo	10-12 mo
Prone	Slight head elevation Rotate head to side	Elbows in line with shoulders Forearm support Lateral weight shifts Lifts head/neck ~45°	Weight shifting Reaching w/ 1 arm Pivot in prone	Push up on extended arms Rocking on hands & knees Pushes self backwards on belly Arm crawls	Transition in/out of: quadruped, sitting, prone Pulls to stand w/ support	Pulls to stand via half kneel	Stands through squat
Supine	Reciprocal & symmetrical kicking and arm swinging		Feet to mouth	Rolls back → belly Push self to sit	Raises self to sit	Transitions out of supine easily & quickly
Sitting	Forward flexed posture Head in line with trunk	Propped sitting w/ support Some head lag w/ pull to sit	No head lag Sits w/ support Lateral shifts	Sits independent when placed (no support) Plays with toy in sit	Protective reactions emerge Transitions into sitting		Pivots on bottom Plays independently with toys

Manipulation of objects

Step 1-10

Types of grasp

Bipedal development (steps 1-7)

Bipedal Development

1. Stepping reflex: up to 2 months

2. Stepping reflex disappears

3. Stepping reflex reappears: 9-12 months

4. Assisted locomotion: 9-12 months 

5. High guard: 10-15 months

6. Low guard: 10-12 wks after initiation of gait

7. Head & trunk erect: 2+ years

whats the hardest

Refinement of skill

• occurs over __ years following walking as advanced motor skills develop

• Walking looks like and adult and has the ratio of an adult by what age?

age

how many falls per hour

Why is walking so hard

Input depends on

Reach and grasp

• starts around:

• refinement period

Observation of functional skill

Observation of functional skills

• Advantages

  • No equipment

  • Useful for infants/children that can't follow directions

  • Looks at real life function

• Disadvantages

  • Not a direct strength measurement

  • Subjective

• Best for

  • Infant/very young children

  • Cognitive/behavioral challenges

MMT

MMT ("break")

• Advantages

  • No equipment

  • Test for specific muscles

  • Reliable for weaker muscle grades

• Disadvantages

  • Less accurate for strong muscles

  • Only tests in one position, not whole range

• Best for

  • 3+

  • Can follow directions

  • Ortho injures/surgeries

handheld Dynamometry

Handheld Dynamometry ("make")

• Advantages

  • Actual #

  • Detects small changes in strength

  • Can be used 28+ months

  • Normative data

• Disadvantages

  • Requires training/standardized procedures

  • Costly equipment

  • Needs recalibrated

• Best for

  • Follow directions

  • Post-surgical/ortho

  • Annual strength monitoring

Isokinetic dynamometry

Isokinetic Dynamometry (entire ROM)

• Advantages

  • Strength through entire ROM

  • Measures concentric & eccentric strength

  • Can measure power

• Disadvantage

  • Expensive, large equipment

  • Specialized training

  • Impractical

• Best for

  • Labs

First trimester

Second trimester

Third trimester
