Q

Movement of intracranial and intraspinal membranes

A

Dura mater - falx cerebri and tentorium cerebelli

  • projects caudally down spinal canal
  • firm attachments to foramen magnum, C2, C3, S2
  • Called reciprocal tension membrane

Arachnoid mater
Pia mater

Q

Involuntary mobility of sacrum between ilia

A

reciprocal tension membrane (dura) attaches to posterior superior aspect of second sacral segment - causes sacrum to move about superior transverse axis at S2

Q

Sphenobasilar synchondrosis (SBS)

A

articulation of sphenoid with occiput

biphasic cycle - flexion and extension

Q

SBS flexion

A

midline bones of cranium move into flexion phase as paired bones move through external rotation

Flexion of SBS pulls dural cephalad, moving sacral base posterior through superior transverse axis of sacrum (at S2) -> counternutation

head widens, decrease in AP diameter - Football head or Ernie head

Q

SBS extension

A

midline bones move into extension phase, paired bones into internal rotation

dural falls caudad, sacrum moves anterior through superior transverse axis (at S2) -> nutation

head narrows, increased AP diameter - Bert head

Q

Cranial Torsion

A

twisting of SBS - anterior and occiput move in opposite directions about AP axis from nasion to opisteon

Named for greater wing of sphenoid that is more superior

Thumb comes back to you on side it’s named

Q

Cranial Sidebending/rotation

A

“crack egg, pour it out”

3 axes:
AP through SBS
2 parallel vertical axes - foramen magnum, center of sphenoid

Named for side of convexity

hands: fingers come in and up; down and out on side it’s named “Down and out in beverly hills”

Q

Cranial Flexion/extension

A

extension lesion: SBS deviates caudad, decreased amount of flexion at SBS

Flexion lesion: SBS deviates cephalad, decreasing amount of extension at SBS

Transverse axis through sphenoid
Transverse axis superior to foramen magnum (jugular notch of occiput)

Hands: Flexion - caudad and fingers spread
Extension - cephalad, fingers closer together

Q

Cranial Vertical strain

A

Sphenoid deviates cephalad - superior vertical strain

Sphenoid deviates caudad - inferior vertical strain

Rotation occur about two transverse axes, center of sphenoid and superior to occiput (foramen magnum)

Hands: Superior - both tip caudad
Inferior - both tip cephalad (thumb back - like the Fonz “hey”)

Q

Cranial Lateral strain

A

sphenoid deviates laterally in relationship to occiput

Left deviation - left lateral strain
right deviation - right lateral strain

Two vertical axes - center of sphenoid, through foramen magnum

Parallelogram head

Hands: Left - left side sphenoid higher - both hands rotate to the right (clockwise)
Right - Right side sphenoid higher - both hands rotate left (counter clockwise)

Baseball to the right side of the head induces a left lateral strain

16
Q

Cranial compression

A

sphenoid and occiput pushed together - blow to back of head

decrease in amplitude of flexion and extension components of CRI

if severe, CRI can be obliterated

17
Q

Temporal bones

A

paired - internal and external rotation
Motion driven by occiput

Occiput moved into flexion -> external rotation and vice versa

cranial strains - temporal bones follow occiput

External rotation of one temporal bone will cause jaw deviation towards that side -> TMJ pain

Internal rotation closes eustachian bone
Fixed external rotation - roaring in ear

18
Q

Conditions associated with temporal bone dysfunction

A 
dizziness
tinnitus
OM
TMJ
HA
Bell's palsy
neuralgia
19
Q

Goals of craniosacral treatment

A

reduce venous congestion
mobilize articular restrictions
balance the SBS
enhance the CRI

20
Q

Venous sinus technique

A

increase venous flow

directly spread apart sutures of cranium overlying occipital, transverse and sagittal sinuses

21
Q

CV4 - bulb decompression

A

enhance amplitude of CRI

first resist flexion phase, encouraging extension phase until still point, then allow normal flexion and extension to occur

Help fluid homeostasis
induce uterine contraction in post-date gravid women

22
Q

Vault hold

A

Index: greater wing of sphenoid
Middle: temporal bone in front of ear
Ring: mastoid region of temporal bone
Little: squamous portion of occiput

23
Q

V spread

A

separate restricted or impacted sutures

24
Q

Lift technique

A

frontal and parietal lifts

aid in balance of membranous tension

25
Q

Temporal rocking

A

TMJ tx

26
Q

Indications for craniosacral tx

A

After birth of a child - facilitates bony remodeling of skull, avoid synostosis

Trauma to PRM - mild forces (orthodontics) or severe forces (MVA)

Dentristry - compromises PRM -> headaches, vertigo, TMJ dysfunction

27
Q

Complications of cranial

A

headaches, tinnitus, dizziness

alter HR, BP, respiration, GI - N/V

28
Q

Contraindication of cranial

A

Absolute: acute intracranial bleed or increased intracranial pressure, skull fracture

Relative: hx of seizure or dystonia; TBI

29
Q

Vagus N.

A

exits jugular foramen

SD: temporal, occiput, OA, AA, C2

Sx assoc with SD: HA, arrhythmias, GI upset, respiratory problems

30
Q

Physiologic cranial strain patterns

A

flexion/extension
torsion
sidebending and rotation

31
Q

non physiologic cranial strain patterns

A

vertical strain
lateral strain
compression

32
Q

Midline bones

A

Sphenoid
Occiput
Ethmoid
Vomer

33
Q

Paired bones

A

Temporal
Parietal
Frontal
