Q

internal obliques create blank trunk rotation

A

ipsilateral

32
Q

external obliques create blank trunk rotation

A

contralateral

33
Q

contraction of trunk flexors and extensors is blank

A

co contraction

34
Q

scm creates blank rotation

A

contralateral

35
Q

co contraction of extensors and flexors increases these pressures

A

intrathecal, intraabdominal, intradiskal

36
Q

thecal sac has to do with the blank

37
Q

point at which normal lumbar lordosis is maintained and painfree

A

neutral spine

38
Q

neutral spine requires blank

A

co contraction

39
Q

when erector spinae is contracted, it shortens which increases blank stability

A

thoracolumbar fascia

40
Q

increased pressure on ivd causes pushing out of the blank which causes increased tension of the blank

A

nucleus pulposus, annulus fibrosus

41
Q

increased height of disc during compression (hoop stress) causes blank compression of z joints

42
Q

annulus fibrosus is arranged in blank layers that have a fiber orientation blank to each other

A

concentric, opposite

43
Q

lumbar vertebrae have a larger blank diameter than blank

A

transverse, a-p

44
Q

primary motion of lumbar spine

A

flex/extend

45
Q

lumbar blank is more limited than blank

A

flexion, extension

46
Q

flexion appears to move farther because of blank involvement

47
Q

80-90 percent of flexion comes from this segment

48
Q

sb is about blank degrees each way

49
Q

rotation and sidebending to opposite sides for neutral mechanics

A

fryettes law 1

50
Q

rotation and sidebending to same side in non neutral

A

fryettes law 2

51
Q

larger disc allows more blank

52
Q

pain on the left side during right rotation may mean blank on the blank side

53
Q

angle between base of sacrum and the horizontal plane

A

angle of the sacrum

54
Q

normal angle of sacrum

55
Q

increased angle increases lumbar blank and anterior blank

A

lordosis, shear/rotation

56
Q

this angle is measured by the obtuse angle of the bodies of l5, s1

A

lumbosacral angle

57
Q

normal lumbosacral angle

58
Q

anterior pelvic tilt in ckc will blank lumbosacral angle but blank sacral angle

A

decrease, increase

59
Q

okc flexion, sacral angle blank, but lumbosacral angle blank

A

increases, increases

60
Q

sway back increases blank between l5 s1 which can cause blank

A

shear forces, pain

61
Q

this inhibits l4 and l5 on s1 anterior shear forces 1 degree due to transverse oriented fibers

A

iliolumbar ligaments

62
Q

disk is blank wedge shaped

63
Q

flexion check reins

A

erector spinae, interspinous lig, supraspinous lig, lig flavum all resist tension.

anterior bodies, annulus resist compression

64
Q

check reins for extension

A

z joint compression, ALL tension, rectus abdominis tension

65
Q

rotation check reins

A

bilateral intertransverse tension, entire annulus tension, contralateral z joint compression

66
Q

sb check reins

A

contralateral intertransverse tension, contralateral erector spinae tension

67
Q

disk is loaded most when in this position

A

sitting slouched

68
Q

sitting with good posture puts blank load on disc compared to standing erect

69
Q

lumbar spine allows the first blank degrees of forward flexion

70
Q

flexion of the sacrum

71
Q

extension of the sacrum

A

counternutation

72
Q

nutation blank sacral angle

73
Q

during counternutation, sacral angle blank

74
Q

anterior pelvic rotation is limited by blank

A

hamstrings

75
Q

sacral nutation eventually stops and sacral counternutation occurs due to further blank because of tight blank

A

anterior pelvic rotation, hamstrings

76
Q

bottom up motion open chain

A

non lumbopelvic rhythm

77
Q

non lumbo pelvic rhythm pulls the blank in this situation

A

sacrum into nutation
