A

Facet: none
SIJ: multi-test regimens (+LR= 3.2, -LR=0.29). no single test was informative

Q

Why do Hancock (2008) and Cleland (2009) fail to reliably confirm or deny use of a CPR for lumbar SMT?

A

Hancock used NTM and reduced symptom duration from 27 to 5 days from original CPR study by Childs (2004), and Cleland compared 1 thrust to 480 CPAs and did not use a control group.

Q

In Cleland’s (2006) validation study of Flynn’s CPR for HVLAT of LBP, what percentage of patients had a successful outcome? What was average decrease in ODI?

A

91.7% within 2 Tx, avg 57% reduction in disability, but it was only a case series

17
Q

What did Oliphant (2004) calculate as the risk of worsening disc herniation or caída equina syndrome?

A

1 in 3.7 million manipulations

18
Q

What is biomechanical specificity suspect, particularly with SMT?

A

Manual therapy is non-specific!
Lee (2005): C5 mob moves O-T3, L3 moves T10-sacrum
Ross (2004): only 46% of lumbar manips are accurate
Chiradejnant (2003): randomly selected technique performed as well as specific one
Haas (2003): random as good as specific for neck pain

19
Q

Using the best evidence, lumbar manipulation in how much safer than NSAIDs? Than surgery?

A

37K to 148K times safer than NSAIDs
55K to 444K times safer than surgery

20
Q

According to Fritz (2005), what is the success rate of HVLAT for patients with hypomobility? What was the success rate of stabilization for patients with hypermobility?

A

74% of hypomobile subjects responded to manipulation (vs. 16.7% of hypermobile subjects)
78% of hypermobile subjects responded to stabilization (vs. 17% of hypomobile subjects)

21
Q

The UK BEAM trial found what level of improvement with low back pain in patients with exercise, SMT, or SMT + exercise at 3 and 12 months?

A

Exercise: small benefit 3 months, no benefit at 12 mos
SMT: small-mod benefit at 3 months, small at 12 mos
SMT + exercise: moderate benefit at 3 months, small at 12 mos
SMT + exercise only slightly better than SMT alone - except for fear avoidance

22
Q

Giles & Muller (2003) investigated manipulation, medication, and acupuncture and found what?

A

Manipulation achieved best overall results (50% improvement in ODI and VAS, 38% on NDI, 47% on SF-36)

23
Q

Rubenstein (2011) did a Cochrane review of SMT concluded what?

A

High quality evidence suggests no clinically relevant difference between SMT and other interventions for improving pain and function.

24
Q

What does MacDonald (2007) say about spinal stability?

A

There is no evidence that TrA and DM co-contract, or that co-contraction helps spinal stability. EMG studies do not show DM as tonically active during any posture.

25
Q

What does Richardson (1999) conclude may be the reason for the delayed TrA contraction seen with limb movements in Hodges & Richardson (1998)?

A

Reflex inhibition producing a decreased activation level of the alpha MN pool at the ventral horn

26
Q

What did Macedo et al (2009) conclude about motor control exercise vs. minimal intervention for LBP?

A

Manual therapy and general exercise were more effective than motor control exercise

27
Q

What evidence suggests core stability is a myth?

A

70% MVC (Max voluntary contraction) needed for strength gains (Stevens 2006) but abdominals do not reach this during “stability” training (Stevens 2006). Abdominal hollowing does not improve stability (Brown 2006, Vera-Garcia 2006), and the TrA cannot contract alone (Cholewicki 2002). Additionally, abdominal strength does not prevent LBP (Helewa 1999, Nadler 2002).

28
Q

Hides (1994, 1996) demonstrated that multifidi strengthening reduced likelihood of back pain recurrence by what amount?

A

Patients recovered in four weeks regardless of group, but 30% recurrence in LM group vs. 80% recurrence in controls. Multifidi recovery was not spontaneous in controls despite pain remission, did occur with LM group.

29
Q

Kader (2000) found what percentage of LBP pts showed multifidi atrophy on MRI? How many had no other findings?

A

80% — about half had no other findings, even with root or leg pain!

30
Q

What is the Danneels (2001) protocol for LM strength?

A

3 exercises: QP leg extensions, trunk lifting from prone, B leg lift in prone
3x/week for 10 weeks
70% 1RM (15-18 reps)
2 second lift/lower with 5 second isometric for each rep

31
Q

Kjaer et al. (2007) found what MRI finding correlated with severity of LBP?

A

Fatty infiltration of lumbar multifidi mm

32
Q

Mayer (2005) studied use of T2 signal to determine muscle recruitment with exercise programs. What exercise routine did researchers find was most effective for recruiting lumbar extensor muscles, and which muscles were most recruited?

A

The multifidus showed the greatest increase, followed by erector spinae, then QL.
Roman chair, 75 deg flexion to 15 deg extension, 3 sets x10 reps, 2 sec concentric and 2 sec eccentric phases, 60s rest between sets, 40 MVC (minimize alternate mm recruitment)

33
Q

Koumantakis (2005) gave both groups exercises, one with stabilization-specific exercise and the other with heavy extensor/flexor exercises, and came to what conclusions?

A

Patient engagement through safe exercising and NOT particular types of exercises may be the key component for successful LBP mgmt. General exercise was more effective than stabilization training.

34
Q

What is the pain adaptation model? What is the evidence for it?

A

Pain results in loss of motor control, not the other way around.
Pain alters proprioception: Capra & Ro (2000)
Pain alters motor control: Hodges & Moseley, Holm (2002), Arendt-Nielsen (1995)
Pain alters muscle spindle sensitivity: Matre (1998)

35
Q

What are Laslett’s (2006) 3 features that rule out ZJ pain?

A
  1. Negative extension rotation test
  2. Dominance of midline pain
  3. Presence of centralization
36
Q

Wilde (2007) interviewed a panel of experts and found what sign was regarded as most likely to indicate ZJ pain?

A

Localized unilateral LBP (94%)

37
Q

Santilli (2006) compared treatment of HLVAT and mobilization for disc protrusion and sciatica (5x/week up to four weeks) and found what changes in pain presence, number of painful days, and MRI findings at 6 month f/u?

A

HVLAT was 28% pain-free in back (vs. 6%) and 55% pain-free in leg (vs. 20%)
HVLAT had 23.6 days of pain (vs. 27.4), 13.9 of which where mod-severe (vs. 17.9)
No changes in MRI for either group
