OPP: Lab Stuff Flashcards
Vault hold: Where do your fingers go?
Index fingers: Greater wing of the spend
Middle fingers: Zygomatic processes
Ring fingers: Mastoid processes
Pinkies: Occiput
Where are your hands in the Fronto-occitipal hold?
Caudad hand underneath occiput
Cephalad pointer and thumb on the greater wings of the sphenoid
What are the axes in Flexion/Extension physiological strain pattern?
Two parallel transverse axises
Flexion is _______ rotation and Extension is ________ rotation.
Anterior; posterior
What is the motion of flexion?
Widening and dropping inferiorly
What is the motion of extension?
Hands come together and move superiorly
What is the axis of Torsion?
AP
How do you name a torsion?
Higher wing of the sphenoid
In ________, the occiput and sphenoid rotate in _________ directions on a single AP axis.
Torsion; opposite
In torsion, how do the index fingers move?
Index finger on the side of the torsion (i.e. GWS) moves superiorly and the index finger on the opposite side index finger moves inferiorly
In torsion, how do the pinky fingers move?
Pinky finger on the side of the torsion (i.e. occiput) moves inferiorly and the [inky finger on the opposite side index finger moves superiorly.
What are the axes of side bending/rotation?
Sidebending: 2 vertical axes
Rotation: 1 AP Axis
What do the two vertical axes run through?
One does through the foramen magnum and one goes through the body of the sphenoid)
In sidebending/rotation, the sphenoid and occiput rotate _________ about the vertical axis.
opposite
In sidebending/rotation, the sphenoid and occiput rotate _________ about the AP axis.
in the same direction
In sidebending/rotation, which is the side of convexity?
The one that drops/feels heavy in your hand (You name for the side of the convexity).
What does each hand feel in side bending/rotation?
The side of the convexity is widening and feels fuller in your hand. The opposite side feels like the fingers are approximating.
How do you feel rotation?
Rotation is felt as the approximated hand moves superiorly and wider hand moves inferiorly
What are the three pathological strain patterns?
Vertical strains, lateral strains, SBS compression
What are the two axes of vertical strain?
Two parallel transverse axes
What is the finger motion in the superior vertical strain?
Hands tip forward;
Forefingers of both hands move inferiorly;
Little fingers of both hands move superiorly
What is the finger motion in the inferior vertical strain?
Hands tip backward;
Forefingers of both hands move superiorly;
Little fingers of both hands move inferiorly
What are the two axes of lateral strain?
Two parallel axes : one through sphenoid and one through foramen magnum
The sphenoid and occiput rotate in the ______ direction in a lateral strain.
Same
How do you name a lateral strain?
You name it for the base of the sphenoid, so as the base of the sphenoid moves toward the side of lateral strain, your fingers will point to the OPPOSITE side.
What do your fingers do in L. lateral strain?
Forefinger shift lateral to the right (sphenoid base turns to the left) and little fingers shift to the left (occipital base turns to the right)
