Clinical Presentation Flashcards
1
Q
1st episode of LBP
A
80-90% asymptomatic in 6 weeks
98% asymptomatic 24 weeks
99% asymptomatic 52 weeks
Those who become disabled with chronic LNP account for 75-90% of cost associated with LBP
2
Q
Genetics Age Education and Socioeconomic Class Workload Sciatic Pain
A
Disc degeneration has degree of inheritance
Age >40/50 low correlation of radiologic findings and clinical sings/sx
Low level formal education and socioeconomic class = inverse (as education goes up,, chronic goes down)
Workload = not a good prognosis with heavy workload
People with sciatica or any leg pain in addition to the back pain have a worse prognosis than someone with just back pain
3
Q
Smoking
A
Blood supply vertebra and disc - accelerated degeneration; coughing
4
Q
Obesity
A
Increases mechanical demands
Longer prognosis
5
Q
Psychological Factors
A
Biomechanical changes (posture) - muscle tension; pain perception; coping; not a cause but effects duration (yellow flag) - can contribute to back pain
6
Q
Comorbidity
A
Any other issues going on with their back - prognosis will not be as good
7
Q
Predictors of recovery in patients with LBP
A
If baseline pain
8

Vertebrae Anatomy
A
Body Disc - annulus fibrosis and nucleus pulposus Vertebral end plates Nerve root canal Zygopophyseal joint (facet)
9
Q
Annulus Fibrosis
A
Review anatomy

Q
Nucleus Pulposus
A
Review anatomy
11
Q
Vertebral End Plate
A
Review anatomy
12
Q
Facet joints
A
Synovial; plane Closed packed position = extension With flexion - they open up With extension - close down Side bending to same side - closed Side bending opp side - opened
13
Q
Facet joint orientation
A
prevents forward slip of the upper vertebral on the lower vertebra
Vertical orientation prevents shear of sup vertebrae on the inferior vertebrae
14
Q
Ligaments and pain
A
Lengthening a ligament will lead to pain
ALL - extension would inc pain
15
Q
Anterior Longitudinal Ligament
A
Extends from ant sacrum to ant tubercle of C1
Connects anterolateral vertebral bodies and disks
Maintains stability and prevents excessive extension of spinal column
16
Q
Posterior Longitudinal Ligament
A
Extends from sacrum to C2, runs with vertebral canal attaching the posterior vertebral bodies
Prevents excessive flexion of spinal column and posterior disc protrusion
17
Q
Ligamentum Flavum
A
Binds lamina above each vertebrae to the lamina below
Prevents separation of laminae
Hypertrophies (gets bigger) with age
18
Q
Supaspinous
A
Connects spinous processes C7-S1
Limits separation of spinous processes
19
Q
Interspinous
A
Connects spinous proceeses C1-S1
Limits separation of spinous processe
20
Q
Intertransverse
A
Connects adjacent transverse processes of vertebrae
Limits separation of transverse processes
21
Q
Iliolumbar
A
Binds transverse processes of L5 to posterior aspect of iliac crest
Stabilizaed L5 and prevents ant shear
22
Q
Quadratus Lumborum
A
palpation
23
Q
Multifidus
A
Palpation
24
Q
Erector Spinae
A
Palpaton
25
Muscles!!!
Make diff BS?
26
Thoracolumbar Fascia
3 layers - separate into Anterior, middle, and post compartments
Provides attachment for transversus abdominis (transverse abdominis attaches to lumbar fascia so can tense when contracted and help with stability)
Spinal stability against shear
Resists segmental flexion
Passive resistance to flexion (fascia has big role in passive support in a flexed position)
27
Nerve Supply and Vascularization!
Review it!
28
Flexion/Extension
Consider muscle imbalances
Structures compressed and lengthened
Inflamed facet joint capsule --> pain with flexion
Ant part of Annulus Fibrosis --> Extension would be painful
Nerve ---> Extension more painful
Erector Spinae --> Passive lengthening, active shortening
29
Tight Hamstrings may
post rotate pelvis --> flattens out lumbar spine (need to check hamstrings with pt with back pain)
30
Tight Psoas
can result in hyper-extension of lumbar spine
31
Roation/Lateral flexion
IVD and Z joints
| Facet joint is also loaded and compressed with weight bearing, discs and facets are compressed
32
Axial Loading
IVD mechanics
| Z joints
33
Red Flags - Back related tumor
Back related tumor = over 50 yo, Hx of cancer, unexplained weight loss
34
Red Flags - Back related infection (spinal osteomyelitis)

| Mechanism
Typically associated with a trauma
39
How to determine the ligament involved in a ligament tear
Know your anatomy
Mechaism of how it happened
Aggracating/Releaiving factors
40
Iliolumbar Ligament Sprain
Most common
Stabilizes L5 on S1
Will complain of pain at mideal iliac crest area
Daignosis through deep palpation
41
Intervention for Iliolumbar Ligament Sprain
Acute = ice, ultrasound, rest
Need to move along with process of healing --> AROM once pain calmed down
Chronic = need to stretch and work the muscles in the area that may tighten the joint
42
LBP with ligament tear is exacerbated by...
lengthening of ligaments
43
Ligament injury can also be associated with
instability of the spine
| Delitto article
44
Muscle Contusions, Strains, Tears
| Mechanism
Trauma
| Muscle guarding following the injury
45
LBP with muscle contusion, strain, tear is exacerbated by
stretch of muscle
| Contraction of muscular tissues
46
Intervention for Muscle contusion, strain, tear
Gradual/controlled return to movement and function
Acute = ice, ultrasound, treat inflammation
Eventually AROM
Further contract muscles more and do strengthening
47
Common site for muscle contusion, strain, tears
Erector Spinae is most common
48
For erector spiane muscle contusion, strain, tear which examination findings would you expect to reproduce the comparable sign?
are we lengthening or shortening the muscle?
49
Diastasis Recti abdominis
Musculoskeletal changes during pregnancy
Ligament Laxity
Pelvic floor dysfunction
Separation of the linea alba
50
Spondylolysis
fracture (lysis) in pars inticularis
| Degenerative change in the spine
51
Spondylolisthesis
shear or slip where one vertebrae slips forward on another
Can have spondylolisthesis without spondylolysis
Both lysis and listethesis are more common in females and younger people
52
Spondylolysis
Mechanism
Most common
Mechanism = congenital or repeated microtrauma
Most common is L5/S1
People who go into extension a lot
53
Spondylolysis
| Examination

```
57
Spondylolisthesis Intervention
```
Correction of muscle imbalances

Surgical if failed conservative
```
58
Postural syndrome mechanism
acute pain or myofascial and articular shortening from a fixed postural impairment
59
Postural syndrome examination
Postural
Limited muscle function - shortened or lengthened

61
Lower Crossed Syndrom Examination Weak
abdominal and glut max
62
Lower Crossed Syndrome Examination Posture
Anterior pelvic tilt, excessive lumbar lordosis, hips flexed, may lead to hamstring strain, knee pain, LBP
63
Disc Herniation Types
Protrusion
Prolapse
Sequestration
64
Disc Herniation Protrusion
Does not escape AF or PLL
65
Disc Herniation Prolapse
Nuclear material remains attached to disc, but bulges posterolaterally into IV canal
Nuclear material escapes AF or PLL
66
Disc Herniation Sequestration
Nuclear material becomes a free fragment in the IV canal
67
Disc Herniation Examination
Lumbar flexion is most painful
Feels better with standing and laying down
LBP and or LE pain/numbness/weakness
ROM - often repeated flexion with peripheralize and extension will centralize
Also aggravating - vasalva/cough/sneeze
Usually unilateral
68
Disc Herniation Examination - Neuro Eval
may have nerve root involvement
Dermatomal sensory, myotomal, reflex changes
Dural signs/neurodynamic tests (SLR/Slump)
Bowel/bladder changes
Posture --> possible lateral shift
69
"LBP with radiating pain intervention"
disc herniation, DDD, radiculopathy
pt education in positions that will reduce strain
Manual traction
Manual therapy to mobilize articulations and soft tissues in the area
Nerve mobility exercises in pain free ranges
70
Degenerative Disc Disease
```
Degenerative changes by 2nd decade
# of annular layers dec
NP hydrophilic mucoid tissue gradually replaced by fibrocartilage
Disc becomes less resilient
Imaging can be misleading
These pt will like flexion
```
71
Radiculopathy
irritation of the sensory nerve root causing pain and/or paresthesia in the distal part of a dermatome
72
Radiculopathy - sciatic pain
low back pain radiating to leg

if have at least 3 of these, stabilization ex should work!
SLR > 91 deg
Age
87
Instability intervention - predictors of non success with stabilization exercises
If 3 of these stabilization ex wont work!
| fear avoidance beliefs quest.

90
Radiculopathy cleland Hypothesis
If pt is complaining most of the leg pain (but also have the back stiffness and stuff) but leg is main complaint - may be good indicator of a radiculoahthy
