[DSA] Intro to OCMM [Nichols] Flashcards
Define osteopathic cranial manipulative medicine
A system of diagnosis and treatment by an OS practitioner using the PRIMARY RESPIRATORY MECHANISM and BALANCED MEMBRANOUS TENSION
Who discovered cranial OMT?
William Garner Sutherland, DO
Where is the primary respiratory motion of cranial omm?
At the SUTURES
Dr. Sutherland believed the cranial sutures behaved like gills of a fish
What are the 5 components of the PRIMARY RESPIRATORY MECHANISM?
- The inherent mobility of the brain and spinal cord
- The fluctuation of the CSF
- The mobility of the intracranial and intraspinal membranes
- The articulatory mobility of the cranial bones
- The involuntary mobility of the sacrum between the ilia
Define:
Motility
Moving or capable of moving spontaneously
The brain and spinal cord have an inherent…
Motility or Mobility?
Mobility
What two things contribute to the inherent mobility of the brain and spinal cord?
Traube-Hering Wave
Glial cells
What is the Traube-Hering Wave?
How is it measured?
Traube-Hering wave= Due to changes in blood flow velocity
Laser Doppler flowmetery
What are the average cranial rhythmic impulse (CRI) on the human skull in normal adults?
What is the range?
Normal adults = 10-14 cycles
Range = 6-14 cycles
Physicians must be ________ in order to palpate the CRI
Physicians must be relaxed in order to palpate the CRI
In order to palpate the CRI…
What must be done?
Physician is relaxed
Contact of the hands is very light
T/F
CRI is a visible motion
FALSE!!!
CRI must be palpated
T/F
If a patient holds their breath, CRI is still palpable
True:
If a patient holds their breath, CRI is still palpable
What is the mneumonic for motion characteristics of the CRI?
R-RADS
What does R-RADS stand for?
Rate
Rhythm
Amplitude
Direction
Strength
What is the sutherland fulcrum?
The functional name given to the straight sinus as the origin of the 3-sickle shaped agents of the falx cerebri and the tentorium cerebelli
What is the reciprocal tension membrane (RTM)?
The meninges and the cord constitute a link between the cranium and the sacrum
What is the “core link”?
The importance in connecting the articular mechanism of the cranium with the sacrum to coordinate action
What is the primary fasica involved in influencing the primary respiratory mechanism?
Meningeal Fascia
The _________, __________, and __________ create a reciprocal tension membrane (RTM)
The Tentorium, Falx Cerebri, and Cerebellum create a reciprocal tension membrane (RTM)
What is the function of the reciprocal tension membrane (RTM)?
Provides constant tension
It allows but limits motion
What are the (4) main poles of attachment for the reciprocal tension membrane (RTM)?
Anterior/superior pole = Crista galli
Anterior/inferior pole = Clinoid processes of Sphenoid
Lateral pole = Mastoid angles of parietals and petrous ridges of temporal bones
Posterior pole = Internal occipital protuberance and transverse ridges
Point on your head for practice:
Where are the…
Coronal, Pteroin, Sphenosquamous, Temporozygomatic, TMJ, Occipitomastoid, Asterion, Lambdoidal and Parietosquamous sutures?
Where is the sagittal suture?
What is the SBS?
Sphenobasillar symphysis
Describe what SBS flexion is:
SBS rises superiorly as the distance DECREASES between the inferior angle of the sphenoid and occiput
I think of an open clam shell = flexion
Describe what SBS extension is:
SBS move inferiorly as the distance INCREASES between the inferior angle of the sphenoid and occiput
Closing clam shell
SBS Motion
Which occurs with exhalation vs inhalation?
SBS Flexion/Extension
SBS Flexion = Inhalation
SBS Extension = Exhalation
SBS Extension is associated with which cartoon characters?
Brian and Bert
SBS Flexion is associated with which cartoon characters?
Stewie or Ernie
What is sacral nutation?
What SBS motion is nutation paired with?
Nodding of base ANTERIORLY
SBS extension
What is sacral counternutation?
What SBS motion is counternutation paired with?
Base moves POSTERIORLY
Counternutation is matched with SBS FLEXION
