Q

Sacral flexion (nutation)

A 
Base moves anterior and inferior
Occurs during spinal extenson

Limited by sacrotuberous

Q

Sacral extension (counter nutation)

A

base moves posteriorly
early spinal flexion
inhalation
not sure what the limiter is for this

20
Q

Sacral rotation

A

right and left rotation around a right oblique axis
right and left rotation around a left oblique axis
lumbar SBR= sacrum rotates left

21
Q

Pubic motion

A

frontal plane: 1.3-2.1 mm
sagittal plane: .4-1.1 mm

pregnancy: 1-70 mm normal

22
Q

anterior sacroiliac ligament

A

Stressed during ilial outflare; hyper hip external rotation

23
Q

Iliolumbar ligament

A

checks posterior ilial rotation and contralateral lumbar sidebend and rotation
prevents lateral shift (we think)

24
Q

Shorter posterior SI ligament

A

limits all ilial motion on sacrm, mainly anterior ilial rotation

25
Q

Longer Posterior SI ligament

A

checks anterior ilial rotation

26
Q

Sacrospinous ligament

A 
checks:
sacral flexion
ipsilateral sacral rotation
ilial posterior rotation
becomes taut when biceps femoris is stretched
27
Q

Sacrospinous ligament

A

does what sacrotuberous does

too deep to palpate

28
Q

Stability of the PG depends on..

A

proper function of the static and dynamic stabilizers

29
Q

Self-locked or closed pack position of SIJ

A

full posterior innominate rotation. ideal position for loading talks
sacral nutation during active extension of the spine and sacrum nutates

30
Q

the PG is not self- locked in…

A

spine neutral: laying supine, stranding, sitting upright, and during gait cycles

31
Q

Form closure

A

the ability to transfer loads through the PG , while keeping the joint surfaces stable.
This depends on static stabilizers being healthy

32
Q

Force closure

A

optimal muscle function provides the PG with dynamic stability

local and global muscle system

33
Q

local muscle system

A

pelvic floor muscles
diaphragm
trans abdom
lumbo sacral multifidi

34
Q

global muscle system

A

opposite lat and glute max
abdominal obliques and adductors
Glute med in weight bearing

35
Q

The lateral system/ sling

A

stabilizes body in frontal plane in single limb support

keeps pelvis level, prevents ilial upslip

36
Q

The deep posterior sling

A

relationships of the biceps femoris with the sacrotuberous ligament; SI stablity relates to biceps femoris length

37
Q

Motor control and PG function

A

as the forces are coming at the spine we should be able to engage our TA and multifidi to secure the spine segmentally
as the forces keep coming we need to fire the bigger muscles
patients with lbp AND pgp LOSE THIS TIMING!

38
Q

Leg length discrepency

A

compensate by side bending to the long leg side
the lumbar spine can be in too much rotation
muscles on concave side are short/ convex side= long

39
Q

Hyperabduction force to the hip

A

causes seperation of the PS

40
Q

Hyperflexion force of hip

A

results in excessive posterior ilial rotation stressing sacrotuberous and iliolumbar ligs

41
Q

Hyperextension force of hip

A

results in excessive anterior rotation of ilium, stressing short and long PSI ligaments

42
Q

Hyper external rotation forces of the hip

A

causes possible damage to anterior SI ligament and possible PS seperation

43
Q

Beighton score

A

want to have a low score

systemic hypermonbility- collagen is looser than a normal persons)

44
Q

Ehler’s Danlos Condition

A

extreme collagen laxity (scores an 8 or 9)

45
Q

Common PG signs and symptoms

A

tender palpation of PSIS and pubis and ligs
unilateral complaint
pain with stair climbing, gait, standing, sitting
referred pain to buttock and post thigh
