Q

To create the parietal axis of motion, where do the bevel of the suture change?

A

Bevel change midway along coronal and lambdoidal sutures creates a hinge for AP axis of motion (coronal plane).

Q

How does temporal bone move during SBS flexion/external rotation?

A

Flexion: Superior border moves anterolateraly; mastoid moves posteromedially.

Extension: superior border moves posteromedially and mastoid moves anterolaterally

16
Q

What is the axis and plane of motion for temporal bone?

A

Axis: oblique axis, modified coronal plane

17
Q

what is the axis and plane of motion for frontal bone?

A

Axis: ant/post
Plane: coronal

18
Q

Explain the motion of borders of parietal bone during SBS flexion

A

External rotation: inferior border moves laterally. Superior border moves inferiorly and medially. increase R/L diameter

19
Q

Parietal bone dysfunction is associated with what clinical signs?

A
  • headache, alteration in seizure threshold, localized pain
20
Q

To treat a pt with parietal lift, how long is force maintained?

A

Force is maintained until a change in quality/quantitiy of CRI motion is palpated, then gently release force on cranium.

21
Q

To perform frontal lift, where is the force applied?

A

During extension/internal rotation, Physician’s interlaced fingers exert a gentle, even and constant pressure against each other and this results in a medial pressure against frontal eminence via hypothenar eminences.

22
Q

what anatomical association does the temporal bone have?

A
  • Middle ear, E-tube, carotid artery, IJV, CN III-XI, and cervical muscle attachments
23
Q

What is the purpose of temporal rocking technique?

A
  • to release CN 9-11 entrapment/dysfunction, E-tube and IJV compression, restricted temporal/occipital articulation, and/or tinnitus
24
Q

what hold is used to perform temporal rocking?

A

Five finger hold

25
Q

State how temporal rocking is performed

A
  • start by encouraging freedom of motion directions (indirect aspect of treatment). To encourage ER ring and little finger exert medial pressure on mastoid and thumb and index direct zygomatic arch superiorly and laterally.
26
Q

what is the purpose of encouraging freedom of motion in the temporal rocking technique?

A
  • to bring the bones into asynchronous motion and then bring to a still point to reverse to symmetric motion
27
Q

How should temporal rocking technique conclude?

A

Pt should be back to synchronous motion. leaving the patient with asynchronous motion, vertigo may result.

28
Q

What is the purpose of performing a V-spread technique?

A
  • TO relieve any peripheral suture tension or restirction.
29
Q

What is the set up in performing V-spread?

A

pt supine, doc at the head of the table. Student places ipsilateral hand with second and third finger on either side of suture and contralateral hand 180 degree opposite with palm or two fingeres in contact with cranium.

30
Q

How is V-spread performed?

A
  1. spread the ipsilateral fingers thats placed on either side of suture
  2. Gently apply force with opposing hand towards dysfunctional suture such that a fluid flow or tide is produced toward fingers making V
  3. Maintain hold until there is a response felt at the suture
  4. reassess motion
31
Q

What is the purpose of CV4?

A

To stimulate body’s inherent capacity (autonomic) to deal with whatever dysfunction is present

32
Q

In performing CV4, the palmer aspect of doc’s hand should contact _

A

lateral angles of occiput, medial to the occipomastoid sutures

33
Q

How is CV4 performed?

A
  1. Note movement of occiput
  2. resist PRM that is being monitored through CRI. Gently encourase extension of the occiput while discouraging flexion
  3. COntinue encouraging extension while discouring flexion until a cessation of CSF fluctuation is palpated. (still point)
  4. Hold for 15 sec or until CRI returns.
  5. Note that this can be done on the sacrum too if cranium is contraindicated.
