SMT-3 Manual, pgs 28-40 Flashcards
- According to van Dieen et al 2003, is TrA involved in spine stability?
No, if taught to contract the core, they would be contracting above required level for stabilization
- Is there a relation between LBP and abdominal atrophy according to Mannion et all 2001
No
- What are improvements in LBP w/ core strength due to
- Better neural activation
- Overcoming psychological aspects of pain
- How did Kavcic et al 2004 relate core and athletes
- Athletes do not specifically activate a group of core muscles
- They use a natural muscular activation pattern
- Conscious effort beyond natural activation decreases stability
- How did Helewa et al 1999 show asymptomatics with weak core
Asymptomatic received back education vs bac education with core strengthening. Found no difference.
546,7. Does poor trunk proprioception predispose athletes to LBP? Author?
No. Silfies 2007
548,9. Who did SR on LBP and core stab (2 articles)? What were the conclusions
Authors:
1. van Tulder 2000
2. Cairnes 2006
Conclusions:
1. Stab/ Core strength is no more effective than general ex to prevent/manage LBP
2. + Effects are secondary to effects that physical ex gives anyway
- According to Lederman 2007 are there studies to date that show that strengthening core muscles (abdominals, TrA) can decrease back pain?
No. Exception being O’Sullivan 1997 for spondylolysis and spondylolisthesis.
- What is RUSI
Rehabilitation Ultrasound Imaging, an alternative method to EMG to indirectly measure the recruitment of ab mm by assessing morphological changes
- Who reviewed reliability of RUSI?
- What 4 variables were used?
- What were the static muscle thickness results?
- Changes in muscle thickness?
- Thickness changes over time?
- Costa 2009.
553. - Thickness (at rest and contracted)
- Thickness changes (measure activity by degree of thickness changes between rest and contracted states)
- Diff in thickness changes over time (improved or deterioration)
- Quality of study (+, -, doubtful, not informative)
Static muscle thickness results - ICC >80% of ICC values ranging from .8-.0 (Very good)
- ICC
- What type of pts were used in studies by Costa 2009 (RUSI study)
Out of 21 studies, only 2 recruited pts with LBP
- Are Costa 2009 results clinically relevant?
Results were as follows:
- ICC >80% of ICC values ranging from .8-.0 (Very good)
- ICC
No, you have to use pts actually seeking care for that condition.
- What did Vera-Garcia 2007 compare?
- Which was most ineffective?
- Which improved spinal stability (at the cost of additional spinal compression)
- Improved spinal stability and without spinal compression
- Ab hollowing vs ab bracing vs natural strategy used in conjunction w/ sudden trunk perturbations
- Ab hollowing
- Ab bracing
- Natural strategies
- According to Davis 2002, what increased spinal compression
Mental processing and stress.
- What does Lederman 2010 say about pain and core exercises?
- Core ex could be a constant reminder of pt’s condition, reinforcing a continuous cycle of pain
- Pt’s should be encouraged to relax their trunk instead of holding it tight
- Who found evidence of lumbar multifidus wasting ipsilateral to LBP symptoms
- What area was measured?
- What subjects were used?
- Who had marked asymmetry
- Where was LM atrophy found
- How soon did atrophy occur?
- Hides 1996
- L2-S1 cross sectional area measured w/ real time ultrasound
- 51 asymptomatic. 26 with 1st episode actue and subacute unilateral LBP
- LBP pts. 31% change in LBP pts vs 3% asymptomatic
- Symptomatic segment, ipsilateral to pain; confined predominantly to that segment.
- 24hrs within injury in one subject
571.). In Hides et al, 1996, what level was mostly affected in regards to lumbar multifidus muscles atrophy?
- L5
- How did Hides et al 1996 train the lumbar multifidus muscles?
- Treatment group. Specific Lumbar multifidus exercises vs control non-active standard medical management.
