25
erector spinae are blank muscles which are movers
spurt
26
spurt muscles have insertions blank axis of rotation
close to
27
multifidus and rotatores are blank muscles because inserition is lateral to central
convergent
28
multifidus and rotatores are blank because they are short going from tp to sp and do stabilization mainly
shunt
29
action to create trunk flexion or posterior pelvic rotation
rectus abdominis
30
standing trunk flexion has blank involvement of rectus abs
no
31
internal obliques create blank trunk rotation
ipsilateral
32
external obliques create blank trunk rotation
contralateral
33
contraction of trunk flexors and extensors is blank
co contraction
34
scm creates blank rotation
contralateral
35
co contraction of extensors and flexors increases these pressures
intrathecal, intraabdominal, intradiskal
36
thecal sac has to do with the blank
meninges
37
point at which normal lumbar lordosis is maintained and painfree
neutral spine
38
neutral spine requires blank
co contraction
39
when erector spinae is contracted, it shortens which increases blank stability
thoracolumbar fascia
40
increased pressure on ivd causes pushing out of the blank which causes increased tension of the blank
nucleus pulposus, annulus fibrosus
41
increased height of disc during compression (hoop stress) causes blank compression of z joints
decreased
42
annulus fibrosus is arranged in blank layers that have a fiber orientation blank to each other
concentric, opposite
43
lumbar vertebrae have a larger blank diameter than blank
transverse, a-p
44
primary motion of lumbar spine
flex/extend
45
lumbar blank is more limited than blank
flexion, extension
46
flexion appears to move farther because of blank involvement
pelvis
47
80-90 percent of flexion comes from this segment
l4-l5
48
sb is about blank degrees each way
20
49
rotation and sidebending to opposite sides for neutral mechanics
fryettes law 1
50
rotation and sidebending to same side in non neutral
fryettes law 2
51
larger disc allows more blank
movement
52
pain on the left side during right rotation may mean blank on the blank side
djd, left
53
angle between base of sacrum and the horizontal plane
angle of the sacrum
54
normal angle of sacrum
30
55
increased angle increases lumbar blank and anterior blank
lordosis, shear/rotation
56
this angle is measured by the obtuse angle of the bodies of l5, s1
lumbosacral angle
57
normal lumbosacral angle
140
58
anterior pelvic tilt in ckc will blank lumbosacral angle but blank sacral angle
decrease, increase
59
okc flexion, sacral angle blank, but lumbosacral angle blank
increases, increases
60
sway back increases blank between l5 s1 which can cause blank
shear forces, pain
61
this inhibits l4 and l5 on s1 anterior shear forces 1 degree due to transverse oriented fibers
iliolumbar ligaments
62
disk is blank wedge shaped
anterior
63
flexion check reins
erector spinae, interspinous lig, supraspinous lig, lig flavum all resist tension. anterior bodies, annulus resist compression
64
check reins for extension
z joint compression, ALL tension, rectus abdominis tension
65
rotation check reins
bilateral intertransverse tension, entire annulus tension, contralateral z joint compression
66
sb check reins
contralateral intertransverse tension, contralateral erector spinae tension
67
disk is loaded most when in this position
sitting slouched
68
sitting with good posture puts blank load on disc compared to standing erect
more
69
lumbar spine allows the first blank degrees of forward flexion
60
70
flexion of the sacrum
nutation
71
extension of the sacrum
counternutation
72
nutation blank sacral angle
increases
73
during counternutation, sacral angle blank
decreases
74
anterior pelvic rotation is limited by blank
hamstrings
75
sacral nutation eventually stops and sacral counternutation occurs due to further blank because of tight blank
anterior pelvic rotation, hamstrings
76
bottom up motion open chain
non lumbopelvic rhythm
77
non lumbo pelvic rhythm pulls the blank in this situation
sacrum into nutation
