Lumbar Spine Exam Flashcards
For the 2021 Revision of LBP CPG, what differentiates “acute” versus “chronic”
Acute < 6 wks of sxs
Chronic > 6 wks
According to the LBP Decision tree, to understand the pt’s LBP experience, you want to assess for pain related psychology distress. What are 3 options for doing so?
- STarT Back Screening tool
- Orebro MSK Pain Questionnaire
- OSPRO -Yellow flag tool
According to the LBP Decision tree, to understand the pt’s LBP experience, you want to collect baseline outcome assessment info. What are 3 options for doing so?
- Oswestry Disability index (ODI)
- Roland-Morris Disability Questionnaire (RMDQ)
- Pt Specific Functional Scale (PSFS)
What are the 5 subgroup classifications for ACUTE LBP?
Acute LBP w/…
1. Movement Coordination Impairments
- Related cognitive or affective tendencies
- Mobility deficits
- Related (referred ) LE pain
- Radiating pain
What are the 3 subgroup classifications for CHRONIC LBP?
Chronic LBP w/…
1. Movement coordination impairments
- Radiating pain
- Generalized pain
If a pt scores 3 or less on the start back, what does that indicate?
Low risk (of disability)
If a pt scores 4 or more on the start back, but their sub score (Q5-9) is 3 or less, what does that indicate?
Medium risk (of disability)
If a pt scores 4 or more on the start back, but their sub score (Q5-9) is 4 or more, what does that indicate?
High risk (of disability)
What does the OREBRO test for?
likelihood to have future disability that interferes with employment
What is the MCID for OREBRO?
12
What is the OSPRO used for?
Yellow flag assessment tool that can be used to determine full-length questionnaire score estimates or ID “yellow flags”
OSPRO = Optimal Screening for Prediction of Referral and Outcome
What 3 categories are included in the OSPRO?
- Negative mood
- depression
- state-trait anxiety
- state-trait anger
- Fear avoidance
- FABQ
- Pain catastrophizing
- Kinesiophobia
- Pain anxiety
- Postive affect/coping
- Pain self-efficacy
- self-efficacy for rehab
- chronic pain acceptance
Describe the interpretation for score ranges on the ODI?
Low/minimal disability = 0-21%
Mod = 21-40%
Severe = 41-60%
Crippled = 61-80%
What is the MCD for the ODI?
11%
what is the range that the Roland-Morris Disability Questionnaire is out of?
What does 0 indicate?
what is the MCD?
0-24%
0 = no disability
MCD = ~5% depending on pop
What is the MCD for PSFS (average score, not single activity score)?
2 points
(3 if single activity score)
Name the SINSS in order
Severity
Irritability
Nature
Stage
Stability
Define severity
Intensity of sxs and extent that they limit normal activity
ex. pain scale, functional limitations (“I can bend over and touch toes but it hurts a little when I do”)
Define irritability
ease in which sxs are produced and time it takes to settle
define nature
type and extent/degree of injury/illness
define stage (SINSS)
acute, sub-acute, chronic, acute on chronic etc
Define stability (SINSS)
how are sxs changing? better/worse/same? stable/unstable?
What are LBP risk factors?
Mod-strong evidence for:
1. smoking (2x more likely)
2. spending > 1hr/day in vehicle (2x)
3. spending > 1 hr/day in activity w/ vibratory forces (mowers, saws, etc.) (5x)
4. full-term pregnancy w/ vaginal delivery (3x)
Weak evidence:
1. Repetitive heavy lifting
2. obesity & poor conditioning
There is a favorable natural history of acute LBP. 30-60% of people recover in ___ week(s)
1 week
There is a favorable natural history of acute LBP. 60-90% of people recover in ___ week(s)
6 weeks
There is a favorable natural history of acute LBP. 95% of people recover in ___ week(s)
12 weeks (3 mo)
According to a 2009 study, what is the greatest predictor of whether someone will have spinal surgery?
of surgeons in local pop
Of pts with LBP, what % have mechanical LBP?
97%
Of pts with LBP, what % have a visceral disease that is causing the pain, leading you to referring them?
2%
What are 4 general visceral disease categories that could be the reason your pt has LBP?
- Abdominal Aortic Aneurysms (AAA)
- GI diseases
- Disease of pelvic organs
- Renal disease
What % of patients with LBP have a nonmechanical spinal condition that isn’t a visceral disease?
1%
What potential nonmechanical and non-visceral conditions can be the reason for a pt’s LBP?
- Neoplasia
- Inflammatory arthritis
- Infection
- Paget’s disease (bone breakdown)
- Scheuermann’s disease (vertebral endplate ~kyphosis)
What interview questionnaire info would you expect for a pt with a bone related tumor?
- Constant pn not affected by position or activity, worse at night & worse w/ WBing
- Age > 50
- Hx of cancer
- Failure of conservative intervention (within 30 days)
- Unexplained weight loss
- no relief w/ bed-rest
T or F: Cauda Equina Syndrome is a neurological emergency!
T
What should you do for a pt with suspected Cauda Equina Syndrome?
Refer immediately to physician/ortho spine surgeon/neurosurgeon/local ED!
**surgery = most successful within 72 hours from onset
Cauda equina syndrome is often assoc w/ nontraumatic massive midline post disc herniation. What spinal segments are most common for CES to occur?
L4-5 > L5-S1 > L3-4
what are the consequences of delayed treatment for cauda equina syndrome?
pt may differ from long-term loss of B&B, sexual function
What are risk factors for cauda equina syndrome?
- LB injury w/ central disc herniation
- central canal stenosis
- spinal fx
