25
Q

spinal stability is increased via tension of the fascia which occurs in a hoop like faschion during contraction of _______

A

abdominal m

26
Q

what term should we use instead of Kegel

A

pelvic floor m training

27
Q

a PFM contraction is described as a ____ and _____

A

squeeze and inward lift

28
Q

what happens to the ischial tuberosities during concentric contraction

A

closer together

29
Q

what happens to the coccyx during concentric contraction

A

flexes towards pubic bone

30
Q

a release of concentric contraction returns PFM to ______

A

baseline

31
Q

what happens when the PFM elongate from resting position / a lengthening contraction

A

eccentric contraction

32
Q

Key pelvic floor m are referred to as …

A

levator ani

33
Q

the pelvic inlet divides what?

A

abdominal and pelvic cavity

34
Q

what passes thru the pelvic outlet

A

vaginal canal and terminal parts of urinary and GI tracts

35
Q

anteriorly situated gap which allows passage of urethra and vagina in females

A

urogenital hiatus

36
Q

list in order of superficial to deep: superficial genital m, pelvic floor/LA, anal sphincters, urogenital diaphragm

A

anal sphincters –> superficial genital –> urogenital –> pelvic floor

37
Q

funnel shaped muscular structure that attaches to the walls of the pelvis

A

Levator ani

38
Q

how is the levator ani or pelvic diaphragm attached to the pelvis?

A

arc de tendineous fascia

39
Q

what muscles make up the lateral wall of the pelvic floor

A

obturator internus and piriformis

40
Q

piriformis forms what part of the pelvic wall

A

part of the posterior wall (as well as lateral)

41
Q

what m are synergists for the hip with the obturator internus

A

obturator externus, quadratus femoris, gemelli

42
Q

what is the role of the obturator internus

A

dynamic stabilizing role

43
Q

how does the OI affect hip?

A

modulates the position of the femoral head in the actabulum during mvmt

44
Q

what 4 m groups make up the core

A
  • pelvic floor
  • TrA
  • MF
  • resp diaphragm
45
Q

what are the attachments of the diaphragm

A

xiphoid process
internal surfaces of lower 6 ribs
lumbar spine
arcuate ligament

46
Q

the “core” starts in the ____ and connects to the ______

A

mid-thoracic region
pelvic floor

47
Q

4 functions of the diaphragm

A
  • trunk control
  • resting tone increases prior to peripheral mvmts
  • tonically active during sustained peripheral activity
  • modulate tone dependent on respiration requirements
48
Q

how do the diaphragm and the pelvic floor move during breathing?

A

they mirror each other

49
Q

describe what happens with the diaphragm and pelvic floor during inhalation

A

descend down - eccentric contraction of PFM activity to spring load

50
Q

describe what happens to the diaphragm and the PFM during exhalation

A

recoil back up

51
Q

proper breathing mechanics result in a _______ in the APC via the function of the diaphragm and PFM

A

piston like effect

52
Q

4 functions of the piston of the APC

A
  • provide massage and mvmt to ABD and pelvic organs
  • assist pumping of blood and lymphatic fluid thru trunk
  • regulate pressure in APC
  • aid in pelvic floor m function via tension and recoil
53
Q

as the diaphragm _____ within the thorax it causes IAP to increase

A

descends

54
Q

IAP acts on the lumbar spine, pushing it _____ and causing the abdominal wall, primarily the ___ to stretch

A

backward
TrA

55
Q

describe how the pelvic floor and pressure in the APC work NORMALLY

A

pelvic floor m contract just before and with the ABD and back m –> increased IAP is directed up toward vocal cords –> result is effective resp or postural maneuver

56
Q

dysfunctional activation of pelvic floor during increase in IAP leads to what 3 things?

A
  • associated with LBP and impaired postural response
  • stress urinary incontinence
  • visceral organ support (prolapse)
57
Q

the pelvic floor m should contract in response to the _____-

A

mvmt of the diaphragm

58
Q

EMG studies show support for what 3 m as facilitators of the pelvic floor

A

Adductors, gluteals and TrA
