PPOM 2 OMM Practical 1: Cranial Strain Patterns

Reference handouts for Labs 3 and 4. Jazz Hands!

Flexion - Air Hand Model

“Swelling”. The operator’s hands move towards the feet, palms move laterally, fingers spread.

Extension - Air Hand Model

“Receding”. The operator’s hands move cephalad, palms move medially, and fingers move slightly together.

Right Torsion - Air Hand Model

Hands rotate in opposite directions. Hand rotates cephalad on right side (side of the higher Greater Wind of Sphenoid).

Left Torsion - Air Hand Model

Hands rotate in opposite directions. Hand rotates cephalad on left side (side of the higher Greater Wind of Sphenoid).

Right Sidebending and Rotation - Air Hand Model

Hand moves caudally with fingers spreading out on side of convexity (right); Hand moves cephalad with fingers approximating on side of concavity (left).

Left Sidebending and Rotation - Air Hand Model

Hand moves caudally with fingers spreading out on side of convexity (left); Hand moves cephalad with fingers approximating on side of concavity (right).

Right Lateral Strain - Air Hand Model

Index fingers move left (towards Greater Wings of Sphenoid) while pinkies move right

Left Lateral Strain - Air Hand Model

Index fingers move right (towards Greater Wings of Sphenoid) while pinkies move left

Superior Vertical Shear - Air Hand Model

Fingers point down towards feet. Hands rotate anteriorly

Inferior Vertical Shear - Air Hand Model

Fingers point up towards head. Hands rotate posteriorly

SBS Compression - Air Hand Model

Either Feels rock-hard like a bowling ball or feels like all the cranial patterns at once
