– Known developmental disorder/ Syndrome

– Unusual skin marks- cafe au lait, etc?

– Spine exam- scoliosis?

– Measure & plot head circumference

Inspection

– Observe resting posture

– Observe spontaneous movements

  smooth, coordinated movements?

– Muscle mass

  Any asymmetry?

  Wasting of small muscles?

  Hypertrophy (esp calves)

  Spasms, tremors, tics?

Sensation:

Know the dermatomes to test*

  – Light touch

  – Pain

  – Temperature

  – Vibration

  – Proprioception

Cortical sensations:

  – Steriognosis

  – Tactile discrimination

Tone:

Resting posture- ‘frog like’

Baby handles like ‘rag doll’?

Head lag on ‘pull-to-sit’?

Ventral suspension- raises head?

Slipping if held under arms?

Abnormal ‘primitive’ reflexes?

Check ‘full range’ of joint movement

Passive tone with fast movements

  – Normal / low tone?

  – Any spasticity / cog-wheel rigidity?

Power:

UL- Shoulders, Elbows, Wrists, fingers, thumb

LL- Hips, Knees, Ankles

Know joint movements & muscle groups

Classify power as:

0= No movement

1= Flicker only

2= Horizontal movement

3= Anti-gravity movement

4= Against some resistance

5= Against full resistance

Deep Tendon Reflexes:

Know technique to elicit DTR

– Can they cooperate for examination?

 

– Use age-appropriate props, or toys

– Record GCS/APVU, mini mental status

– Developmental disorder/ Syndrome

– Signs of meningitis?

– Measure & plot head circumference

 

 

 

Inspection

– Observe resting posture

– Observe spontaneous movements

  smooth, coordinated movements?

  Any splints, walking aids visible?

– Involuntary movement?

  Spasms, tremors, tics?
