Q

How is a vertical strain named?

A

Named for the direction of the base of the sphenoid

17
Q

What are the axes for vertical strains?

A

Transverse

18
Q

What type of strain is this?

“1st fingers move toward the practitioner, pinky fingers move away from practitioner”

A

Inferior strain

(It’s like the head rolls back into lap)

19
Q

What type of strain is this?

“1st fingers move away from practitioner, pinky fingers move toward practitioner”

A

Superior strain

(It’s like your hands are rolling forward and away from you)

20
Q

How are SBS torsions named?

A

Named for the higher greater wing of the sphenoid

21
Q

What is the motion that occurs in a SBS torsion?

A

Motion happens in opposite directions about this axis

22
Q

Describe that palpation you would feel in a torsion SBS SD

A

1st finger and pinky of one hand move superiorly

While the other hand moves inferiorly

23
Q

Whta is the sidebending rotation SBS SD named for?

A

Named for the convexity developed in the cranium

(Side of fullness)

24
Q

What motion occurs for a sidebending rotation SBS SD about the axes?

A

Motion happens in the SAME direciton about the SAGITTAL axis

Motion happens in the OPPOSITE direction on the VERTICAL axis

25
Q

Describe what you’d palpate in a sidebending rotation SBS SD

A

Named for the side that feels “fuller” = 1st finger and pinky move away from each other

Opposite side “shrinks” = 1st finger and pinky move toward each other

26
Q

What is a compression SBS SD?

A

Significant trauma

SBS is compressed

27
Q

How can you remember which way sacral nutation is?

A

Sacral base goes toward the nuts

(Anterior)

28
Q

SBS flexion causes sacral ___________

SBS extension causes sacral __________

A

SBS flexion causes sacral COUNTERNUTATION

SBS extension causes sacral NUTATION

29
Q

Where would trauma occur to cause a lateral strain?

A

Anterior or Posterior to the SBS

30
Q

Where would trauma occur to cause a vertical strain?

A

Superior or inferior to the SBS

31
Q

Where would trauma occur to cause a torsion?

A

Hit with a roll

“Twisty motion”

32
Q

Where would trauma occur to cause a sidebending rotation?

A

Direct blow to one side

33
Q

What is the motion at the base of the sacrum in SBS flexion?

A

Counternutation

34
Q

What is the motion of the apex of the sacrum in SBS flexion?

A

Anteriorly

35
Q

Where is the axis of motion of the sacrum?

A

Superior transverse axis

36
Q

SOS dear lord save my soul

A
