Intro to OCMM Flashcards
things to observe when screening
face - forehead and supransal vertical folds
orbits and zygomae - nose and nasolabial crease - mouth
top, side and back of head
things to palpate during an ocmm examination
sutures
muscles - suboccipitals, occipitalis, temporalis, masseters, frontalis
lympahtics - suboccipital, a and p chains, supraclavicular and submental
characteristic motions of the CRI rate: rhythm: amplitude: strength: direction:
rate is 10-14 bpm
rhythm should be regular, tide of the ocean
amplitude - significant SD may diminish amplitude
strength - significant SD and vitality of the pt may greatly impact strength
direction - longitudinal and symmetric, SD causes asymmetry
flexion
SBS moves _______, the distance between the inferior angle of the sphenoid and occiput ______
Basi-occiput and Basi-sphenoid move superiorly
occipital squama moves inferiorly and posteriorly
greater wing moves inferiorly and anteriorly
paired with ______
stewie
SBS moves superiorly
inferior angle of the sphenoid and occiput decreases
paired with inhalation
extension
SBS moves _______ and sphenoid and occiput have a ______ axis of rotation
paired with _______
brain
SBS moves inferiorly with dereased angle
transverse axis
paired with exhalation
finger placement for vault contact
index fingers on greater sphenoid wings (inferior to frontozygomatic sutures) middle fingers anterior to the ear ring fingers on the mastoid pinky on the occiput palms on the parietals thumbs gently on the frontal
finger placement for frontal occipital contact
occipital hand - resnts on the table cradling the patients head and occiput
frontal ahnd - thumb pad on one greater sphenoid wing
index pad on other greater sphenoid wing
palm on anterior aspect of frontal bone
rest elbows on the table
finger placement for becker contact
thumbs on the greater sphenoid
index on mastoid
middle and pinky fingers on the occiput with middle finger posterior to OM suture
palms cup the occiput and posterior aspects of the parietals
increased transverse diameter, forehead wide and sloping, AP diameters the same on both sides; saggital suture flat or even slightly depressed
describes what type of SBS motion
flexion
rotation on a transverse axis, symmetrical positioning of both anterior quadrants in external rotation
wide orbits
eyeballs prominent
zygomatic tuberosities flattened
pterygoid processes equally posterolateral
low wide palatine arch with flared alveolar processes
ER of the maxillae
both frontozygomatic angles incdreased
physiologic motion of flexion
pt with this physiologic motion ahve a hx of asthma and nasopharyngeal complaints
extension
long narrow head, decreased transverse diameter, beetle-bro type forehead, AP diameter is same on both sides, rigid saggital suture
extension
inferior SBS, distance between the inferior angle of the sphenoid and the occiput increases toward the mid-position
basi-occiput and basi-sphenoid moves inferiorly
occiputal squama moves superiorly and anteriorly
greater wing moves superiroly and posterirly
physiologic motion of extension
narrow orbits eyeballs recessed zygomatic tuberosities prominent pterygoid processes anterior high, narrow palatine arch with alveolar processes more vertical frontozygomatic angles decreased
physiologic motion of extension
evidence of rotation of the transverse axis with symmetrical positioning of both posterior quadrants in internal rotation
extension
ears close to ehad
mastoid portions are posteromedial
mastoid tips are anterolateral
elevated condylosquama
extension
flexion is paired with nutation/counternutaiton
counternutation
extension is paired with nutation/counternutation
nutation
nutation- the base moves ______ and the apex moves _____
base moves posteriorly
apex moves anteriorly
still point
CRI dampens until you cannot feel it while holdning a neutral position by placing the SBS in the midpoint of the available ROM
DO that developed OCMM
william garner sutherland, 1900 graduate of kirksville
five components of PRM
inherent mobility of the brain and spinal cord
fluctations in the CSF
the mobility of the intracranial and intraspinal membranes
articulatory mobility of the cranial bones
involuntary mobility of the sacrum between the ilia
cranial motion d/t changes in blood flow velocity and is measurable by laser doppler flowmetry
traube-hering waves
functional name given to the straight sinus as the origin of the 3 sickle-shaped agents of the falx cerebri and the tentorium cerebelli
sutherland fulcrum
meninges and the cord constitute a link between the cranium and the sacrum
reciprocal tension membrane
refers to its importance in connexcting the articular mechanisms of the cranium with the sacrum to coordinate action
core link
what creates the RTM
the temtorium and falx cerebri and cerebellum
attach to the bones of the vault and base and hold them under constant tension
allows but limits motion
where does the RTM attach to the vault
anterior/superior pole - crista galli
anterior/inferior pole - clinoid processes of sphenoid
lateral pole- mastoid angles of parietals and petrous ridges of temporal bone
posterior pole - internal occipital protrubernece and transverse ridges
SBS stands for
sphenobasilar spymphysis
where the basisphenoid and basiocciput joint to form a synchondrosis
where does the dura attach
foramen magnum
posterior body and disk of S2 in spinal canal
axes of motion of the sacru m
ST respiratory axis - (most anterior) - PRM assocaited at S2
MT postural axis - middle - anterior aspect of S2
IT pelvic/ilial axis - S3 - movement of ilia on sacrum
SBS extension is paired with what motion of the sacrum
nutation
base moves anterior
apex moves posterior
SBS flexion is paired with what motion of the sacrum
counternutation
base moves posterior
apex moves anterior
what team of researchers demonstrated cranial motion in cats
observed spontanteous motion at pareital bones
adams, heisey, smith and briner
pterion
frontal, parietal, temporal, and sphenoid bones join here
asterion
pareital, occipital, temporal
bregma
parietal bones and frontal bones
lambda
parietal bones and occiput
