|
Name the physiological strain patterns.
|
Flexion, Extension, Torsion, Side Bending Rotation
|
|
|
Name the non-physiological strain patterns.
|
Lateral strain, vertical strain and SBS synchondrosis compression
|
|
|
Describe the etiology, axis, and naming of a flexion/extension strain pattern.
|
E - Birth, genetics
A - Two transverse axis D - Named for position of SBS (F/E) |
|
|
What is the motion preference is a flexion strain pattern?
|
SBS is elevates and A/P diameter is decreased, Transverse diameter increased (Ernie). There is a motion preference for flexion, external rotation and the sacrum favors counternutation.
|
|
|
Where is your fingers positioned in a vault hold?
|
Place index on pterion, middle finger on squamous portion of temporal bone, ring finger on the mastoid portion of temporal and little finger on lateral angle of the occiput. Thumbs should touch and rest lightly on bregma.
|
|
|
Describe the etiology, axis, motions and naming of a torsion.
|
E- Birth, Blow to anterior or posterior quadrant of head
A- A/P from nasion to opisthion M- Sphenoid & occiput rotate in opp. directions on SBS N- Nae for the side of the superior sphenoid bone |
|
|
What would be your palpatory finding with a vault hold in a patient with a left torsion.
|
The index finger will rotate towards you and the little finger will rotate away. The right hand will be opposite.
|
|
|
Describe the etiology, axis, motions and naming of a side bending/rotation (SBR) strain pattern.
|
E-Trauma (ex: blow to the left side of the temporal and parietal region will result in a R SBR stain
A-Two parallel vertical axes (sidebending)- one through the center of the sphenoid and one through foramen magnum; One A/P axis (rotation) - Opisthion to naision M- The sphenoid and occiput rotate opposite directions on the parallel axes and in the same on the A/P axis (inferior on the side of convexity) N- Side of convexity of the SBS |
|
|
What palpatory findings will you find in a left SBR?
|
The left index and little fingers (widen) spread apart and move inferiorly (away from you) while the right come together and move towards you.
|
|
|
Describe the etiology, axis, motions and naming of a lateral strain.
|
E- Trauma to one side of the head ant or post to SBS; birth trauma or compression in utero
A- Two parallel vertical axes- one through base of sphenoid one through foramen magnum M- Rotation of sphenoid & occiput in same direction N- By direction of base of the sphenoid (R or L) |
|
|
What would be the palpatory findings in a left lateral strain?
|
Index fingers shift laterally to the right and the little fingers shift to the left
|
|
|
Describe the etiology, axis, motions and naming of a vertical strain pattern.
|
E-Traumatic superior or inferior force on either the anterior or posterior cranium
A- Two parallel transverse axes M- The sphenoid and occiput rotate in the same direction (one into flexion and one into extension) N- Direction of the posterior surface of the body of the sphenoid (superior or inferior) |
|
|
What is the palpatory findings in a superior vertical strain?
|
The index fingers rotate inferior and the little fingers rotate superior
