Craniosacral motion Flashcards
What makes up the primary respiratory mechanism (PRM)
CNS + CSF + Dural Membranes + cranial bones + sacrum
What is the normal rate of CRI
10-14 cycles per minute
What factors decrease the rate and quality of the CRI
- Stress (emotional, physical)
- Depression
- Chronic fatigue
- Chronic infections
What factors increase the rate and quality of the CRI
- Vigorous physical exercise
- systemic fever
- following OMT to the craniosacral mechanism
The dura mater is the outermost membrane It is thick, inelastic and forms the falx cerebri and tentorium cerebella. What does it attach
- Foramen magnum
- C2
- C3
- S2 (posterior superior aspect)
What are the midline bones involved in flexion and extention of the SBS?
- Sphenoid
- Occiput
- Ethmoid
- Vomer
What movement do the paired bones of cranium do during flexion of the SBS?
What implication does this have on the shape of the head?
external rotation
-Wider and decrease in anterioposterior diamter
Sacrum during SBS flexion
counternutation
Where is index finger in Vault hold?
Greater wing of sphenoid
Where is middle finger in vault hold
Squamous portion of temporal bone
where is ring finger in vault hold
mastoid process of temporal bone
Where is pinky finger in vault hold
squamous portion of occiput
where is thumbs in vault hold
-hovering over sagittal sutures; NOT touching
What are the physiologic strain patterns
- Flexion and extension
- Torsion
- Sidebending and rotation
What are the nonphysiological strain patterns
- Vertical
- Lateral
- Compression
A cranial torsion is named how
for the greater wing of the sphenoid that is more superior
Describe the axis of rotation in torsion
-one AP axis and sphenoid and occiput rotating in opposite directions
Describe the axis in Side bending rotation
- 2 distinct motions that occur simultaneously about three separate axes
- Rotationg occurs about an AP axis through the SBS (same axis as a torsion strain) but in the same direction
- The sidebending occurs about 2 parallel vertical axes (one through foramen magnum and the other through the center of the sphenoid)
How is a sidebending rotation strain pattern names
names for side of convexity made by the sidebending
Compression strain of the SBS can result in severely decreased CRI. It is usually due to what?
Trauma, especially to the back of the head
(Occipital) condylar compression (CN XII) can result in what
poor suckling in the newborn . . Dysfunctions of CN IX and X at the jugular foramen can also cause suckling dysfunctions in the newborn
What are the goals of Craniosacral treatment
- reduce venous congestion
- Mobilize articular restrictions
- Balance the SBS
- Enhance the rate and amplitude of the CRI
What are the indications to craniosacral treatment
- After the birth of a child
- Trauma to the PRM
- Dentistry
What are some complications that can occur with craniosacral treatment
- Headaches
- tinnitus
- dizziness
- alter heart rate, blood pressure, respirations, and GI irritability
What are the absolute contraindications to craniosacral treatment?
- Acute intracranial bleed or increased intracranial pressure
- skull fracture
What are the relative contraindications to craniosacral treatment
- known seizure history or dystonia
- traumatic brain injury
The motion of the temporal bone is driven by what
occiput
Dysfunction of which cranial nerve can cause symptoms similar to Tic Douloreux
V2
