Lecture 6 Flashcards by Alla Demarte

What is the presumed natural history of LBP?

“80-90% of attacks of low back pain recover in about
six weeks, irrespective of the administration or type of
treatment.”

Why bother treating LBP? Isn’t LBP a

self-limiting disorder?

No, the natural history of LBP is characterized by persistent or recurrent episodes.

What is the relationship between bed rest and the reduction of LBP and Sciatic?

Acute LBP:
 Bed rest less effective than advice to stay active

Sciatica:
 No difference

Bed rest associated with long term disability

Bed rest results in:
 Lumbar multifidus atrophy, trunk flexor shortening

What is the relationship between acupuncture and the reduction of acute/chronic LBP?

Acute LBP
 Current lack of evidence precludes conclusions

Chronic LBP
 More effective than no Tx or sham Tx
 Not more effective than other therapy options
 Possibly a useful adjunct

What is the relationship between message therapy and the reduction of subacute to chronic LBP?

Subacute/Chronic LBP
 May be beneficial for pain and function
 Larger effects with multimodal approach
▪ Exercise
▪ Education

What is the relationship between lumbar supports and the reduction of LBP?

Prevention
 Moderate evidence supports not more effective
than lifting advice

Treatment
 Conflicting evidence of low quality
 May improve function in short term for Cx
 No definitive evidence as yet supports the use
of orthoses after spinal interventions or in
painful conditions of the Cx or Lx spines.

What is the relationship between transcutaneous electrical nerve stimulations and the reduction of chronic LBP?

Chronic LBP (TENS vs. Placebo)
 Conflicting evidence of effectiveness for pain
 No evidence of effectiveness for disability
 No difference in use of medical services
 No difference in work status

What is the relationship between heat and ice on the reduction of LBP?

 Heat: moderate evidence of small, short term pain
reduction
 Cold: current lack of evidence precludes conclusions

What is the relationship between shoe insoles and the reduction of LBP?

 Strong evidence that insoles do not prevent LBP

What are the LBP treatment guidelines for acute- subacute LBP?

 STRONG-evidence in favour of SMT when
compared to sham for pain, function and health
improvements in the short-term (1-3 months).

 MODERATE-evidence to support SMT and Mob +
STT combined with usual medical care (UMC) in
comparison to UMC alone for pain, function and
health improvements in the short-term.

What are the LBP treatment guidelines for chronic LBP?

 MODERATE in favour of SMT in
comparison to sham for pain, function and
overall-health in the short-term.

 MODERATE- evidence in favour of SMT &
mob & STT combined with exercise or
UMC in comparison to exercise and backschool
was established for pain, function
and quality-of-life in the short and longterm.

What are the options recommended for non-specific LBP by the treatment guidelines?

 Keep diagnosis under review at all times
AND
 Promote self management: advise patients to exercise, be
physically active and to maintain normal activities as possible
AND
 Offer appropriate drug treatments to manage pain and to help
people keep active
AND
 Offer one or more of the following treatments
 Exercise program (8 sessions)
 Manual therapy (9 sessions)
 Acupuncture (10 sessions)

What is the better functional outcomes of a patient with LBP?

 patient compliance with self-exercise and therapy attendance
 application of exercise and manual therapy

What is the worse functional outcomes of a patient with LBP?

 women
 electrotherapy for pain management
 therapeutic ultrasound for shoulder impairments.

What are some under-utilized treatments for LBP?

 Therapeutic exercise

 Treatment of depression

What are some over-utilized treatments for LBP?

 Muscle relaxants
 Traction
 TENS units
 Corsets

15% of LBP is determined e.g. (trauma, stenosis, infection)

85% of LBP is non-sepcific LBP, TRUE or FALSE

True

What are the role of the transversus abdominis?

Contributes to spine stability by Insertion with
the thoracolumbar fasica. Influence to increase intra-abdominal pressure but not disc pressure
 Decreases SI joint laxity

What are the 2 changes that occur to the transversus abdominis?

▪ Delayed

▪ Attenuated

What is the role of Lumbar multifidus?

 The largest muscle to cross the lumbosacral
junction
Designed to stabilize the lumbar spine in prolonged flexion or extension
 Controls segmental flexion
 Provides 2/3 of the segmental stability at the lower
lumbar spine by dispersing load through the
thoracolumbar fascia
 Contracts in an anticipatory fashion

Lumbar multifidus origin, action and insertion

Insertion: SP or vertebrae
Origin: TP of vertebrae
Action: extension and lateral rotation

Lumbar Multifidus muscle changes after back injury include what?

Structural remodelling, adipose and connective tissue but not muscular atrophy

What morphological changes can occur to the lumbar multifidus muscle during back injury?

1. atrophy 2. fatty infiltration 3. elasticity

Stabilization exercises work by doing what?

 Addressing deficits in strength, endurance, and function |  Improvements in function lead to decreases in pain and disability

What stabilization plan should you make for your patient?

```  4 weeks of training  2 sessions of motor control training  Prescribed 3 sets of 10 reps b.i.d.  Improved TrA feedforward activation with arm flexion & arm extension  Improvements retained at 6 Months ```

LBP Recurrence: comparison between medical management and stabilization exercises?

``` Medical Management  Year 1: 84%  Years 2-3: 75%  Idiopathic  As severe as original episode ``` ``` Stabilization Exercise  Year 1: 30%  Years 2-3: 35%  Traumatic  Less severe then original episode ```

What is included in the Aberrant motion assessment?

```  Painful arc in Flexion (or return)  Difficult return from flexion (Gower’s Sign) or thigh climbing  Instability Catch (lateral flex or rotation)  Reversal of lumbopelvic rhythm * At least one of these to be present ```

What is involved in the prone instability test?

1. P-A test for pain provocation  Identify painful segments 2. Repeat P-A with hips extended  Positive finding: previously painful segments become less painful
