Q

May & Rosedale (2009) reviewed existing LBP CPRs against established criteria and found what about the derivation and validation studies?

A

Derivation studies were mostly high quality, but none of the validation studies were. Most did not pass the lowest level of evidence hierarchy. Manipulation CPRs had limited and contradictory evidence of clinical utility.

Q

Stanton (2010) and Haskins (2015) studied CPRs for readiness to apply them to LBP. They both concluded they were not ready for different reasons. What were they?

A

Stanton found studies used single arm design and therefore may just list prognostic indicators rather than treatment indicators.
Haskins (2015) found no studies to look at validation or impact analysis.

Q

How specific can we be with thoracic manipulation?

A

Herzog & Symons (2001): peak pressure pt moved 9.8 mm (probably not delivered to target segment)
Ross (2004) found 3.5 cm as avg error from target joint—more cracks=more accuracy
Bereznick (2002): 38.75 mm displacement on TPs, 33.25 mm for SPs during thoracic thrust if no skin lock

Q

What are 8 benefits of applying a thrust?

A
  1. Facilitate movement
  2. Relieve pain
  3. Increase circulation
  4. Immediate neurophysiological reflex response (mm relaxation)
  5. Immediate strength increase
  6. Release entrapment (capsules, meniscoids)
  7. Powerful psychological effect
  8. Quicker than mobilization
22
Q

What are the actual risks of spinal manipulation?

A

Margarey & Haldeman (2002): 1/50K to 1/5.85 million cervical manipulations
Cassidy (2008): cervical Complications 1/50K to 1 in 4M, association between chiro and VBA stroke less than PCP visits
Haldeman & Rubenstein (1992): lumbar <1/10M manipulations

23
Q

Murphy (2010), Kerry & Taylor (2006) concluded there’s no benefit to screening for risk of VBA - what was the reasoning and what 6 tests are recommended instead?

A

VBI test not validated
Instead use:
1. CN exam and VOMS
2. BP testing
3. active signs of dissection
4. PMH of artherosclerosis (maybe)
5. US
6. functional CAD position tests

24
Q

What is the comparative stress on VBA of HVLAT vs diagnostic testing/ROM? What is the level of force required to cause a dissection?

A

Symons (2002) SMT was 6.2% of resting length at OA level and 2.1% at C6 - mechanical failure occurs at 139-162%
SMT uses approx 1/9 the strain of a mechanical failure and equal or less strain as Dx/ROM testing
Wuest (2010) 2.3% strain during thrust vs 13% during PROM testing and 8.5% during VBI test

25
Q

Thomas et al (2013) investigated blood flow during manipulations and found what?

A

No changes in flow during any neck position or manipulation/distraction—change in one vessel caused compensation in the others

26
Q

What did Hutting (2013) conclude about the statistics for the VBI test?

A

Sensitivity 0-57%: high risk of false negatives
Specificity 67-100%: not helpful since a false positive is not dangerous for a patient with VBI

27
Q

Which four cranial nerves are most impacted by a VBA/ICA dissection in progress? What other signs/Sx occur? Kerry & Taylor (2010), Thomas (2011)

A

Hypoglossal n., glossopharyngeal n., vagus n., accessory n.

ICA: Horner’s syndrome (82%), temporal/retro-orbital HA (75%), facial palsy (60%), ptosis (60%)

VA: occipital HA (85%), ataxia/balance (67%), dizziness (25%)

28
Q

What are the 3 components AAMT argues should be added to a definition to distinguish HVLAT from mobilization?

A
  1. Thrust (short and fast)
  2. Audible pop
  3. Pt cannot prevent forces

Bonus: chiros add Paraphysiological range

29
Q

What pre-manipulative tests are recommended for cervical spine?

A
  1. Lateral glide test (Fernandez-de-las-Penas 2005, Jull 1994)
  2. Flexion rotation test
30
Q

What are the mechanics of a cervical manipulation (position, speed, acceleration, force)?

A

30 deg rot, 46 sidebend/sideshift, 2 deg flexion/ext
4.8 deg off barrier, 11 deg through barrier (Ngan), 13 deg displacement (Triano)
Time: 80-100 ms CS, 120-200 ms LS
Speed: 72 deg/s avg, 127 deg/s peak
Acceleration: 2183 deg/s/s
Force: peak 118N

Ngan 2005, Klein 2003, Herzog 1993, Tríanos & Schultz 1994

A

10x increase (24 N to 238 N)
Herzog & Symons 2001

32
Q

What evidence exists that joints move after manipulation?

A

Thoracic: Gal (1997) found 6-12 mm of anterior and 3-6 mm lateral translation from pre-load to post-thrust
SIJ: Hungerford (2004) found pts with pelvic pain rotated their WBing inominates anteriorly and translated inferiorly (opp for pain free individuals) suggesting asymmetry; Timgren & Soinila (2006) found restoration of pelvic symmetry after HVLAT w/ 15% relapse. Results independent of length of time pain had occurred.

33
Q

How much did jaw opening increase after PA manipulation in neck pain patients (Mansilla-Ferragut 2009)?

A

3.5 mm

34
Q

What is the amount of treatment indicated for neck pain that is acute vs. Chronic according to Bale & Newell (2005)?

A

Acute: 4 Tx, 3 weeks
Chronic: 4-10 Tx, 10 weeks
<7% required >10 Tx

35
Q

What are three physiologic effects of SMT?

A
  1. Stimulate receptors in short and deep intervertebral mm (Bolton & Budgell 2006)
  2. Intervertebral disc diffusion (Beattie 2013)
  3. Increase afferent discharge of mechanoreceptors from disc, facets, mm, ligaments (Colloca 2004)
36
Q

How did Indahl (1997) prove that lumbar multifidi are connected to discs?

A

1 mL injection into lumbar facet caused rapid reduction in multifidi EMG
Electrical stim to disc annulus stimulates mutlifidi

37

Clinical tests have no established validity and “poor to unacceptable” inter-examiner reliability

41

44
Q

McGrath (2006) argued that the SIJ is impalpable for what 4 reasons?

A
  1. Depth of 5-7 cm under skin
  2. Inominate faces medically on sacrum
  3. 7 anatomical layers to palpate through
  4. Only 1-2 deg of motion in rotation and 1 mm of translation in any direction
45
Q

What did Freburger & Riddle (2001) conclude about Inter-testing reliability, sensitivity, and specificity for SIJ positioning tests?

A

The standing/sitting flexion, Gillet’s, supine to sit, prone knee flexion and sacral spring all have poor inter-tester reliability, low sensitivity (0.46-0.49), and low specificity (0.38-0.64). Authors concluded we cannot palpate to find which “position” the SIJ is in.

Poor Inter-tester reliability was also found by Robinson (2007) and Holmgren (2007).

46
Q

What did van der Wurff (2006) conclude about pain referral patterns for SIJ?

A

Fortin’s area (3cm horizontal x 10cm vertical) inferior to PSIS pain with the absence of tuber area (ischial tuberosity) pain indicates likely SIJ pain

47
Q

What did Mens et al (1999) conclude about use of the ASLR in supine?

A

It validly demonstrates a step of 5mm at the upper margins of the pubic bones in pain patients caused by anterior rotation of inominate on symptomatic side and correlates STRONGLY with mobility of the pelvic joints in patients with pelvic pain.

48
Q

What is the AAMT recommended best practice for SIJ clinical Dx?

A
  1. 3/5 tests (Laslett’s or van der Wurff)
  2. Fortin’s area
  3. ASLR
  4. Trigger points: BL54 (piriformis), BL23 (QL lat to L2)
49
Q

What direction should you manipulate into for the SIJ?

A

It doesn’t matter (Clements 2001, Hartman 1997&2006, Stuge 2006)

50
Q

What is are 6 goals of HVLAT to SIJ?

A
  1. Increase force closure/strength of QL, LM, glute Max
  2. Improve feed forward activation times
  3. Decrease pain
  4. Increase ROM
  5. Reduce disability
  6. Correct positional fault? (Contradicting evidence)
51
Q

What is the evidence of use of stabilization exercises for SIJ pain?

A

Mens (2000): no improvement with stabilizing exercises vs control
Stuge (2004): improvement with stabilization, but patients also received SMT
Nilsson-Wikmar (1998), Dumas (1995): no difference between stabilizing exercise and no exercise

52
Q

According to Holm et al (2002), Kavcic (2004), Stuge (2004, 2006), what muscles provide lumbopelvic stability?

A

All trunk mm—not just IO, TrA, LM
