Q

ME: postisometric relaxation - direct technique

A

Physician takes pt into restrictive barrier. Pt provides activating force to ease of motion

  • isometric contraction - where the distance bt the origin and the insertion of the muscle remains the same as the muscle conttacts will stretch the internal connective tissues
  • golgi tendon organs senses this change in tension in the muscle tendons and causes a reflex relaxation of the agonist muscle fibers -> physician can then engage new restrictive barrier

Q

Hip-drop test

A

Assesses the SB (lateral flexion) ability of the lumbar spine and thoracolumbar jxn

  • normal: lumbar spine SBs toward the side c/l to the bending knee, smooth convexity of lumbar spine on i/l side and i/l iliac crest should drop more than 20-25 degrees
  • positive test = drop of iliac crest less than 20-25 degrees and anything less than a smooth convexity in the lumbar spine
58
Q

Straight leg raising test (Lasegue’s test)

A

Test for sciatic nerve compression. Normal hip should be flexed to 70-80 degrees.
-pain = d/t hamstring tightness or sciatic n problems
Braggard’s test= lowers leg just below where pain was felt and dorsiflexes the foot to stretch the sciatic nerve. If no pain with this test -> tight hamstrings are the problem

59
Q

Seated flexion test

A

Assesses sacroiliac motion -> evaluates SD in the sacrum and pelvis

60
Q

Standing flexion test

A

Assesses iliosacral motion

-evaluates possibility of SD in the leg or pelvis, most commonly the innominate

61
Q

Pelvic side shift test

A

Determines if the sacrum is in the midline
-it is often seen in a flexion contracture of the iliopsoas (psoas syndrome). A flexion contracture of the R iliopsoas will cause a + pelvic shift test to the left

62
Q

Trendelenberg’s test

A

Assesses gluteus medius muscle strength. Pt picks up one leg off of the floor. Normally the glut medius should pull up the unsupported pelvis to keep it level. + test = pelvis falls -> weakness in the glut medius (superior gluteal n)

63
Q

Lumbosacral spring test

A

Assess whether the sacral base is shifted posterior

+ test = little or no springing -> indicates sacral base moving posterior

64
Q

Lumbosacral spring test will be positive in all dysfxns in which the sacral base moves posterior

A

+ test = u/l sacral extension, sacral margin posterior, sacral base posterior, and when sacrum rotates backward on an oblique axis

65
Q

Backward bending test (Sphinx test)

A

Determines if the sacral base has moved posterior to anterior
+ test = part of the sacral base moves posterior
Normally, sphinx movement ( lumbar extension) causes the sacral base to move anterior
-physicians thumbs become more symmetric with lumbar extension, part of the sacral base moved anterior
-if the physicians thumbs become more asymm with lumbar extension, part of the sacral base has moved posterior

66
Q

70
Q

HVLA thoracics & ribs- Kirksville Krunch

Q

Iliopsoas m = psoas major m and iliacus m

-maintaining lumbosacral angle

A

Origin: T12-L5 vertebral bodies
Insertion: lesser trochanter of femur
Action: primary hip flexor
SD: usually from prolonged shortening of the muscle
-pelvic side shift, + thomas test, SD of the upper lumbar segement

113
Q

L4-L5 intervertebral disc is at the level of

A

Iliac crest

114
Q

T10 dermatome at the umbilicus, which is anterior to

A

L3 and L4 intervertebral disc

115
Q

Sacralization

A

One or both of the TPs of L5 are long and articulate with the sacrum. May lead to early disc degen

116
Q

Lumbarization

A

Failure of fusion of S1 with the other sacral segments. Less common than sacralization

117
Q

Main motion of lumbar

A

Flexion/extension

118
Q

Motion of L5 influences the sacrum

A

SB of L5 cause a sacral oblique axis to be engaged on the same side
Rotation of L5 will cause sacrum to rotate to opposite side

119
Q

Herniated nucleus pulposus

A

Most often between L4-5 and L5-S1

  • herniated disc in the lumbar region will exert pressure on the nerve root of the vertebra below
  • Ex: herniation between L3-4 = affect nerve root of L4
120
Q

Psoas syndrome

A
  • precipitated from prolonged positions that shorten the psoas
  • pain in low back sometimes radiates to groin. Ache, muscle spasm
121
Q

Psoas syndrome sxs/signs

A
  • incr pain when standing/walking
  • positive thomas test
  • tender point medial to ASIS
  • nonneutral dysfxn of L1 or L2
  • positive pelvic shift test to c/l side
  • sacral dysfxn on an oblique axis and c/l piriformis spasm
122
Q

Psoas syndrome txment

A

Acute spasm may benefit from ice to decr pain and edema. Do not use heat initially. Do CS to anterior psoas then HVLA, ME to high lumbar spine.
-only stretch chronic psoas spasm

123
Q

Example of key lesion for psoas syndrome

A

L1: F RrSr

L2-5: N RlSr

124
Q

Spondylolisthesis

A

Anterior displacement of 1 vertebra in relation to the 1 below. Often occurs at L4 or L5. Usually d/t fatigue fractures in the pars interarticularis of the vertebra

125
Q

Spondylolisthesis s/s

A
  • incr pain w/ extension activities
  • tight hamstrings b/l
  • stiffed-legged, waddling type gait
  • positive vertebral step-off sign
  • goals of OMM: reduce lumbar lordosis and SD, HVLA is CI
126
Q

Spondylolysis

-no anterior displacement

A

Defect usually of the pars interarticulars without anterior displacement of the vertebral body
-oblique views will identify the fracture of the pars interarticularis (collar of scotty dog)

127
Q

Spondylosis

A

Degenerative changes within the intervertebral disc and ankylosing of adjacent vertebral bodies
-anterior lipping of the vertebral bodies

128
Q

Cauda equina syndrome

A

Pressure on the nerve roots of the cauda equina usually d/t a massive central disc herniation
-saddle anesthesia, decr DTRs, decr rectal sphincter tone, loss of bowel and bladder control

129
Q

dextroscoliosis

A

Curve that is SB L = scoliosis to the R

130
Q

Levoscoliosis

A

Curve that is SB right = scoliosis to the L

131
Q

Severity of Scoliosis

A

Mild- Cobb angle = 5-15
Moderate - Cobb angle = 20-45
Severe - Cobb angle = > 50
-resp fxn is compromised if the thoracic curvature is > 50
-CV fxn is compromised if the thoracic curvature is > 75

132
Q

Short leg syndrome: anatomical or functional leg length discrepancy results in:

A

Sacral base unleveling
Vertebral SB and rotation
Innominate rotation

-MCC is hip replacement

133
Q

Short leg syndrome s/s:

A
  • sacral base unleveling: sacral base will be lower on the side of the short leg
  • Anterior innominate rotation on side of short leg
  • Posterior innominate rotation on side of long leg
  • Lumbar spine will SB away and rotate toward the side of the short leg
  • Lumbosacral (ferg’s) angle will incr 2-3 degrees
  • First the iliolumbar ligaments, then the SI ligaments may become stressed on the side of the short leg
134
Q

Short leg syndrome: get standing postural x-rays

A

If femoral head difference is > 5 mm, consider heel lift

135
Q

Short leg syndrome: heel lift guidelines

A
  • final lift height should be 1/2-3/4 of the measure leg length discrepancy unless there was a sudden cause of the discrepancy -> in that case lift the full amount
  • the fragile (elderly, arthritic, osteoporotic, acute pain) pt- begin with a 1/16 (1.5 mm) heel life and increase 1/16” every 2 weeks
  • flexible pt- begin with 1/8” (3.2 mm) lift and incr 1/8” eery 2 weeks
  • max of 1/4” may be applied to the inside of the shoe
  • max heel lift possible is 1/2” -> if need more need i/l anterior sole lift
136
Q

Sacrospinous ligament

A

Originates at the sacrum and attaches to the ischial spines.
This ligament divides the greater and lesser sciatic foramen

137
Q

Iliolumbar ligament

A

Originates from the TP of L4 and L5 and attaches to the medial side of the iliac crest. Often the first ligament to become painful in lumbosacral decompensation

138
Q

Piriformis m

A

Origin: at the inferior aspect of the sacrum
Insertion: greater trochanter of the femur
Action: ER, extends thigh and abducts thigh with hip flexed.
Innervation: S1 & S2 nerve roots
-sciatic nerve can run through piriformis -> hypertonicity can cause butt pain that radiates down the thigh, but not usually below knee

139
Q

Innominates rotate about what axis

A

Inferior transverse axis of the sacrum

-also the axis which an ant/post innominate rotation SD occurs

140
Q

Sacral motion

A

Respiratory- motion occurs about the superior transverse axis of the sacrum at S2
Postural- motion occurs about the middle transverse axis of the sacrum

141
Q

Sacral torsion rules

A
  1. When L5 is SB, a sacral oblique axis is engaged on the same side as SBing
  2. When L5 is rotated, the sacrum rotates the opposite way on an oblique axis
  3. The seated flexion test is found on the opposite side of the oblique axis
