SMT 421-480 Flashcards
- What is a (+) ER test?
pain with extension combined with rotation towards the painful side
- Who obtained a concensus from expert Australian & NZ for LBP
Wilde et al 2007
- What did 94% of the panel agree on
localized unilateral LBP
- How did Delitto et al 1995 diagnose lumbar segment instability?
if LBP is caused by minimal perturbations
- presence of lateral shift deformity
- short term relief from manipulation
- trauma
- use of oral contraceptives
- bracing improve symptoms
- Paris 1985 and Maitland 1986 diagnose LSI by?
presence of a step off between adjacent Spinous processes
hypermobility on PPVIM and PAIVM
- O’Sullivan in 2000 diagnose LSI by?
- giving way, slipping out or locking with presence of reverse lumbopelvic rythm
- presence of posterior shear stress using posterior force
- What 3 authors relate LSI to aberrant motions such as an instability catch?
Paris 1985 ; Nachemson 1985 and Ogon et al 1997
- What is an aberrant motion?
- a sudden acceleration or deceleration of movement
and movements occuring outside the plane of motion like SB or rotation with flexion occurs from a flexed position
- Have aberrant motions ever been related to symptoms or abnormal movements in imaging studies?
No concurrent validity to date
- What did Barnes et al 2009 contribute to LSI studies
a variation from normal spine coupling
- Who attempted to demonstrate consistent coupling patterns?
Legaspi & Edmonds 2007
- Did Legaspi & Edmonds 2007 find a consistent coupling pattern between SB and Rot in Lx spine?
No.
- Is there evidence to support the use of coupled motion to evaluate or treat LBP?
No.
- Is coupling detectable by palpation?
No. The motion is only +/
- What 6 criteria did Paris 1985/2003 use as exam findings for LSI?
- Instability catch
- Hypertrophied band horizontal raised muscle tone on standing
- Step off on standing that disappears on lying
- shaking/shuddering on forward bending (Ogon et al 1997)
- Imbalance on SLR
- Grade 5 or 6 on PPIVM
- Kirkaldy-Wallis & Farfan 1982, O’Sullivan 2000 use what findings in their studies?
- painful arc during motions
- inability to stand erect s assistance from hands
- How did Magee 1997 diagnose LSI?
Prone instability test: pos test if painful c Lx compression PA at rest but no pain while actively lifting legs. NO VALIDITY.
- What did Friberg 1997 use?
Radiographs: Axial Compression c wt on shoulders, Axial Traction hanging from a bar.
- What did Friberg 1997 measure?
AP translation: accurate for detection of LSI.
- What did Hayes et al 1989 disprove in regards to radiographs?
- Who else supported the lack of clinical value in films?
- 42% of asymptomatic subjects have at least one segment exceeding the instability thresholds.
- Pitkanen et al 1997
- What 2 categories did Hicks et al 2005 and Cook et al 2006 categorize LSI?
- a. Radiographic instability (structural instability), major disruption of passive osseoligamentous constraints
b. Clinical Instability (segmental instability, neuromuscular system symptoms inconsistent with finding on radiographic analysis
- According to Senntag and Maraiano 1976 what is considered excessive motion?
- What is treatment for these patients?
- Greater than 4 degrees translation or 10 degrees rotation
- Fusion if conservative treatment have failed
- In regards to Algarni et al 2011 systematic review what test may be useful in ortho clinic to diagnose structural LSI?
- How is it performed?
- Sensitivity?
- Specificity?
- Positive likely hood ratio?
- Passive lumbar extension test
- Prone, PT lifts both LEs into extension to 30 cm while providing traction (+) test indicated by increased pain that disappears on return to starting position
- 84%
- 90%
- 8.8
- Any tests for segmental instability?
- No all tests have limited ability to diagnose
