36
Q

what is the direction for compression?

A

37
Q

what are the physiologic strains?

A
  • torsion
  • sidebending
  • rotation
38
Q

what are the pathologic strains?

A
  • vertical
  • lateral
  • compression
39
Q

venous sinus drainage - occipital sinus

A
  1. two middle fingers placed tip to tip on inion
  2. hold until softening
  3. keep fingers in same position and move one finger width down toward foramen magnum
  4. when reaching as close as possible to foramen magnum as possible, approximate wrists, allowing middle fingers to come apart - this decompresses the occipital condylar parts from facets of atlas - used for colic in babies
40
Q

treatment for colic in babies?

A

VSD - occipital sinus

41
Q

venous sinus drainage - transverse

A
  1. pads of little fingers on inion while other fingers are spread out along superior nuchal line
  2. the weight of the fingers completes
  3. wait for softening / warmth
42
Q

venous sinus drainage - straight sinus

A
  1. 5th fingers on inion and thumbs on bregma

2. hold until softening / warmth

43
Q

venous sinus drainage - superior sagittal

A
  1. crossed thumbs over sagittal suture and spread suture
  2. left thumb is to right of suture, right thumb is to the left - spreading in direction the thumbs are pointing
  3. move one finger width at a time until you reach bregma
  4. hold until softening / warmth
  5. for metopic suture - place finger pads of both hands along each side of metopic suture of frontal bone and gently spread - wait for softening
44
Q

parietal lift

A
  1. fingertips at superior edge of suture line where temporals meet parietals
  2. thumbs should meet at vertex but not be touching patient’s head
  3. link thumbs together and then try to pull them apart
  4. lift them gently toward head of table with fingertips disengaging from underneath temporals
45
Q

treatment for headache at vertex?

A

parietal lift

46
Q

treatment for frontal sinus headache?

A

frontal lift

47
Q

what is the goal of a frontal lift technique?

A
  • cause internal rotation of frontals to disengage them from their related bones and lift them anteriorly
  • this allows them to externally rotate and widen at the ethmoid notch
48
Q

treatment: frontal lift

A
  1. hypothenar eminences on lateral angles of frontal bones and interlace fingers over but not in contact with, forehead
  2. attempt to draw fingers of one hand from fingers of the other
  3. hypothenar eminences exert and influence internal rotation on lateral angles of frontals
  4. coordinate this action with the lifting of the frontals anteriorly until you feel lateral angles moving into external rotation
  5. upon release gently remove hands
49
Q

what does the CV-IV technique do to the PRM/CRI?

A 
encourages extension (or internal rotation) 
- allows potency of CSF to be directed from ventricular system to periphery of the body
50
Q

CV-IV: treatment

A
  1. volleyball grip
  2. slide under head allowing lateral angles of occiput to rest on them
  3. follow PRM/CRI into extension by pulling your hands toward you, bringing the occiput into extension and then holding that position
  4. wait for still point (warmth / stillness)
  5. wait until you feel PRM/CRI pick up again
  6. gently remove hands
51
Q

treatment for release any peripheral sutures / sinus pressure over a specific area of overriding or stuck sutures?

A

V spread

52
Q

V spread

A
  1. place index and middle fingers of one hand on either side of the immovable suture while the palm of the other hand is placed 180 degrees across from it
  2. as suture is gently spread, pulsation will be felt somewhere under the palm
  3. two fingers of that hand may be placed over this region of pulsation to direct fluid back toward spreading fingers
53
Q

treatment for patient who is anxious / nervous / frightened / agitated?

A

temporal rocking

54
Q

temporal rocking

A
  1. temporal hold
  2. gently rock to either the right of left by leaning on the forearm on that side
  3. 10 second to move from one forearm to the other
