Craniosacral motion Flashcards
What are parts of primary respiratory mechanism PRM
CNS + CSF + dural membranes + cranial bones + sacrum
the 5 elements of PRM
1 inherent motility brain and spinal cord
2 fluctuation CSF
3 movement intracranial and intraspinal membranes
4 articular mobility of the cranial bones
5 involuntary mobility of sacrum between ilia
spinal cord changes during respiration
lengthens and things in exhalation
shortens and thickens on inhalation
Cranial Rhythmic Impulse
10-14 cycles per minute
factors that decrease rate of CRI
stress
depression
chronic fatigue
chronic infections
factors that increase rate of CRI
vigorous physical exercise
systemic fever
following OMT to craniosacral mech
where does dura mater attach
foramen magnum, C2 C3
S2 (respiratory axis)
Sphenobasilar synchondrosis
articulation of sphenoid with occiput
flexion SBS
midline bones of cranium and dura move cephalad (flexion)
paired bones cranium externally rotate
causes sacrum to counternutate (extend)
change in head shape in flexion
widen head and decrease AP length
extension SBS
midline bones move caudal and sacrum flexes
paired bones internally rotate
what are the midline cranial bones
sphenoid, occiput ethmoid vomer
strains at SBS
flexion/ext torsion sidebending and rotation vertical strain lateral strain compression
R torsion SBS
R sphenoid wing is most superior
anterior cranium rotate in one direction
posterior cranium rotate in other
AP axis
in a sidebending rotation strain of SBS what are the axis
AP axis: anterior and post cranium rotate same direction
2 vertical axis,: foramen magnum and center sphenoid
physiologic SBS motions
torsions and sidebending/rotations
SBS extension
SBS deviates caudad
decreasing amount of flexion
SBS flexion
SBS deviates cephalad
decreasing amount of extension
axis in vertical strains
2 transverse axis
superior vertical strain
sphenoid deviates superiorly
L lateral strain
sphenoid deviates to the L
axis in lateral strain
2 vertical
1 sphenoid and 1 foramen magnum
palpation of cranium feels like parallelogram
lateral strain
compression
decreased movement and can get rid of CRI
from trauma usually to back of head
vagal SD can be from what cervical origin
OA AA and C2
tinnitus, vertigo or hearing loss
CN VIII
poor suckling in newborn, most likely SD
compression XII from occipital condyles
also dysfunctions IX X in jugular foramen
Purpose venous sinus technique
increase venous flow through sinuses
venous sinue technique
spread apart sutures on cranium on occiputal, transverse and sagittal sinuses
CV4
enhance amplitude CRI
resist flexion phase and encourage extension then allow restoration
bulb decompression
another name for CV4
what enhances amplitude of CRI
CV4 technique
vault hold purpose and hand position
asses SBS strains index finger on great wings sphenoid middle finger on temporal bone ring finger on mastoid little finger on squamous part of occiput
V spread
separate restricted or impacted sutures
lift technique
frontal and parietal lifts to balance membranous tension
Indications craniosacral Tx
after birth
trauma to PRM
dentistry
Absolute CI to craniosacral Tx
acute intracranial bleed or increased intracranial P
relative CI to craniosacral Tx
known seizure or history of dystonia
traumatic brain injury
