lumbar Flashcards
what percentage of individual can be given a patho-anatomic diagnosis with back pain
20%
What is the general consensus regarding risk factors for developing low back pain
No definitive cause has been identified. Risk factors are multifactorial, population specific and only weakly associated with development of low back pain
what is the consensus regarding the clinical course of low back pain
It can be described as acute, subacute, recurrent or chronic
- due to the high prevalence of recurrent and chronic back pain interventions should focus on preventing recurrences and helping people transition into chronic stage
What are the recommended general diagnosis or PT classification of low back pain
- mobility impairments of the spine and SIJ
- referred or radiating pain into the lower extremity
- generalized pain
What differential diagnosis recommendations are made for outside referrals
- clinical findings suggestive of serious medial or psychological pathology
- functional limitations and impairments are not consistent with MSK back pain
- symptoms are not resolving with treatment
* strong evidence for recommendation
what self reported questionnaires are recommended for back pain
- Roland Morris
2. Oswestry
What is the general recommendation regarding Thrust manipulations
- strong recommendation for patients with back pain and falling into the mobility deficit classification
- Thrust and non-Thrust are recommended for improving spine and hip mobility
- reducing pain and disability for subacute and chronic low back pain and back related leg pain
What are the general recommendations regarding trunk coordination, strengthening and endurance exercise with low back pain
- use them to reduce pain and disability in patients with subacute and chronic back pain with movement coordination impairments AND POST LUMBAR MICRODISCECTOMY
* strong evidence
what are the general recommendations regarding centralization and directional preference exercises
- repeated motions exercises and procedures to promote centralization
- recommended for all stages acute to chronic in patient with mobility deficits
* strong evidence
what are the general recommendations regarding flexion based exercises
- helpful in reducing pain and disability in older patients radiating pain
- recommended for subacute and chronic stages
* week evidence
what are the general recommendations regarding nerve mobilization exercises
- helpful with radiating pain
- subacute and chronic stages
* week evidence
What are the general recommendations regarding traction for low back pain
- intermittent type traction
- prone when presenting with subacute nerve root with peripheralization or positive cross SLR
* emerging evidence - DON’T do traction with acute/subacute nonradicular or chronic back pain
* moderate evidence
What type of education interventions are discouraged
Anything that directly or indirectly promotes perceived threat or fear associated behaviors including (1) extended bed rest (2) in-depth pathoanatomic explanations of low back pain
*moderate evidence
What types of educational interventions are encouraged
- Understanding the pathoanatomic “strength” of the spine
- neuroscience of pain perception
- favorable prognosis for spine pain
- use of active pain coping strategies that decrease fear and catastrophizing
- early resumption of activity even when they are still in pain
- Recognition of improvements in function not just pain
* moderate evidence
what is the general recommendation for pregressive endurance exercise and fitness training in indvidual with back pain
- strong level of evidence for
(1) Moderate to high intensity exercise for patients with chronic low back pain without generalized pain
(2) incorporating progressive, low intensity, submaximal fitness and endurance activities into the pain management and promotion strategies for patients with chronic low back pain with generalized pain
Describe the prevalence of low back pain
- one year incidence of first ever back pain is between 6.3 and 15.3%
- episodes of low back pain are from 1.5-36%
- Reoccurrence of low back pain is 24-33%
- Women higher than men
- severity progresses with age until 60-65 years
- lower socioeconomic status is associated with increased prevalence, longer episodes and worse outcome
- jobs with higher physical demands have greater prevalence of back pain (material handling jobs 39% and sedentary jobs 18.3%)
- Working and non working prevalence is about the same
what are the two major categories of risk factors for developing low back pain
- individual factors
2. activity related factors
What are the individual risk factors for developing low back pain
- some relation to genetic, body build and early environment influences
- cardiovascular hypertension and lifestyle (weight and smoking) are risk for “sciatica”
how do psychosocial factors influence risk for developing low back pain
- They play a larger prognostic role that physical factors
- kineisophobia has a strong link to the development of chronic back pain
- distress and depression have a strong influence over the early stages of recovery
What variable suggest a more favorable outcome in individuals with back pain
- lower pain levels
- higher job satisfaction
- active coping style
what variables appear to low impact on recovery from low back pain, yet may influence prevalence of low back pain
- history of low back pain
- job satisfaction
- educational levels, marital status, number of dependents, smoking, working more than 8 hour shifts, occupation, size of company
- complex back problems recover as well as simple back problems
describe the risk factors for developing low back pain in adolescence
very similar to adults
- psychosocial variable are strong predictors of chronicity
- sporting activities such as rowing and weight lifting have higher risk for developing low back pain
- girls as much as 3:1
What is the over conclusion on risk factors for low back pain
GRADE B - Current evidence does not support definitive causes for initial low back pain
- risk factors are multifactorial, population specific and only weakly associated with development of low back pain
Describe the role of imaging in identifying a pathoanatomic cause of low back pain
poor association between anatomy and pathology
- 20-76% of individuals without symptoms have anatomic impairment
- 32% of asymptomatic individuals compared 47% of symptomatic individuals have “abnormal” MRI findings
- Boos followed asymptomatic patients for 5 years and found a stronger association between job characteristics and pyschological aspects with development of back pain than radiological findings
what are the different temporal stages of back pain
acute - less than one month
subacute - 2-3 months
chronic - greater than 3 months
* challenge with these descriptions is that low back pain is episodic in nature with episodes occurring in as much as 65% of individuals and as often as every 2 months in t
what factors are predictive of developing recurrent or chronic low back pain
- history of previous back pain
- excessive spine mobility
- excessive joint mobility in other joints
what prognostic factors put someone at risk for developing chronic pain
- presence of symptoms below the knee
- psycological distress or depression
- fear of pain, movement and reinjury or low expectations of recovery
- high pain intensity
- passive coping style
what is the first step in evaluating low back pain
Rule out medical red flags and nerve root compression
What does the evidence suggest about treatment classifications for low back pain
strong support for classifying patients into subgroups
