Sensation:
Know the dermatomes to test*
– Light touch

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?

LL- Hips, Knees, Ankles
Know joint movements & muscle groups
Classify power as:
0= No movement
1= Flicker only
