OPP Lect 24

OPP Lect 24 Cranial Membrane Strains

Dural reflections 1.Falx Cerebri. 2.Falx Cerebelli. 3.Tentorium Cerebelli. 4.Diaphragma Sellae (covers the pituitary gland).
Membrane motion during cranial flexion 1.Falx cerebri: shortens Anteriorly & Posteriorly, lowers. 2.Tentorium cerebelli: moves anteriorly & flattens (pulled out by temporal bones).
Membrane motion during Cranial Extension 1.Falx cerebri: Lengthens A & P, rises. 2.Tentorium Cerebelli: moves posteriorly & becomes lax/ tent shaped.
Reciprocal Tension Membrane System 1.Motion occurs around the straight sinus. 2.Fulcrum automatically shifts within the straight sinus. **everything is shifting around the straight sinus.
Functions of the Cranial Membranes 1.Structural integrity during dev. 2.Division of hemispheres & cerebellum. 3.Transmission & reabsorption of CSF. 4.Drainage from venous sinus. 5.Shock absorption/stress transmission.
Which Cranial membrane function limits cranial mobility Shock absorption/stress transmission. **will try and stop force transmission to the other side in response to trauma.
Limitation of cranial mobility: Falx cerebri Ant-post, Sup-inf
Limitation of cranial mobility: Falx Cerebelli Sup-inf
Limitation of cranial mobility: Tentorium Cerebelli Lateral
How would a tentorium cerebelli strain present? how would you treat it? Dec lateral amplitude. **Treat w/ temporal decompression OR balanced membranous tension.
How would a falx cerebri strain present? how would you treat it? Dec Ant-post amplitude. **Treat w/ frontal or parietal lift OR balanced membranous tension.
Balanced membranous Tension Treatment technique 1.Find neutral point of strain pattern by exaggerating abnormal motion. 2.Position towards ease of motion. 3.Hold until a still point is reached. 4.When motion returns, recheck for symmetry.
How does balanced membranous tension affect still points? It can cause a still point (no CRI) when compression or restrictive pressure is applied in step 2. **Allows everything to relax
In Balanced membranous Tension, after a still point has been induced, what occurs? It allows the inherent motion of primary respiratory motion to be a corrective force while everything is relaxed. **A wave of inherent motion is restored w/ greater amplitude with more symmetry.
path of Venous sinus flow Superior & Inferior sagital sinuses and the straight sinus drain into the confluence of sinuses. From there, it drains out the transverse sinuses and down the sigmoid sinuses.
Compressin of the 4th Ventricles (CV4 technique) Causes still point and then inherent motion. Has positive effect on sinus flow. **Avoid occipitomastoid suture.
4 main ways Cranial bones affect venous sinuses 1.Emissary veins pass through cranium. 2.CT in sutures is continuous w/ periosteal dura. 3.Sutures have elasticity. 4.Muscle tension strains the sutures. **dysfunction in bones OR membranes results in obstruction of free BF.
Venous Sinus drainage treatment Indications: HA, Upper respiratory infection. Technique: 1.Transverse sinuses (superior nuchal ridge). 2.Occipital sinus (below inion). 3.Superior sag sinus (sagital suture)
How can C2 & C3 somatic dysfunctions cause dural tension? Myodural bridge: Rectus capitus posterior minor is attached to the posterior atlantooccipital membrane.
How can sacral restriction contribute to head somatic dysfunction? Inner/meningeal dural layer in the cranium is continuous with the dural sac attaching to S2.
Are Primary Respiratory Mechanism (PRM) and CRI the same thing? NO, CRI is the head's response to the PRM. **PRM can be palpated anywhere in the body
How can PRM be used diagnostically? Since the PRM is felt anywhere on the body, areas of somatic dysfunction WONT transmit the PRM.
PRM in the body related to CRI CRI Flexion: Ext rotation. CRI Extension: Internal rotation.
When using balanced membranous tension elsewhere in the body it is called _______? Balanced Ligamentous tension.
