27
What is the Canadian Cervical Spine Rule used for?
Decision rule for detection of clinically important injury ( fx, dislocation, ligamentous instability)
28
What is the first Question you consider for the Canadian Cervical Spine Rule?
Any HIGH-risk factor that mandates radiography? 1. Age 65+ 2. Dangerous mech (fall from 3+ ft/5 stairs, axial load to head, high-speed MVC) 3. Paresthesias in extremities * if any of the above are true, refer for imaging!
29
If a pt does not have any high-risk factor that mandates radiography what question do you consider next?
Any LOW-risk factor that allows safe assessment of ROM? 1. Simple rear-end MVC 2. Sitting position in ED 3. Ambulatory at any time 4. Delayed onset of neck pn 5. Absence of midline CS tenderness
30
If a pt does NOT have any HIGH-risk factors that mandate radiography AND DOES have a low-risk factor that allows for safe assessment of ROM, how do you proceed?
Assess neck AROM rotation
31
According to the Canadian Cervical Spine Rule, if a pt is unable to ROT neck R/L 45 deg, how should you proceed?
Refer to imaging
32
T or F: the Canadian Cervical Spine Rule is really good at ruling OUT a clinically important injury related to the CS but poor at ruling IN.

How do you interpret a +LR > 10 and a -LR < 0.1
generate large and often conclusive shifts in probability
36
How do you interpret a +LR 5-10 and a -LR 0.1-0.2
generate mod shifts in probability
37
How do you interpret a +LR 2-5 and a -LR 0.2-0.5
generate small but sometimes important shifts in probability
38
How do you interpret a +LR 1-2 and a -LR 0.5-1
alter probability to a small and rarely important degree
39
What are the S&S of vertebrobasilar insufficiency?
5 D's: Dizziness Diplopia Dysarthria Dysphagia Drop attacks + Nausea & vomiting Sensory changes
40
T or F: the Vertebral Artery test/ VBI test is not a good screening tool
T It has poor sensitivity so a neg test is NOT a meaningful finding
41
What is included in the cluster test for radiculopathy?
1. ULNT median 2. Cervical rot (<60 deg) 3. Cervical distraction test 4. Spurling's *best diagnostic accuracy for radiculopathy is w/ clustering of tests (If all 4 +, Sp = 0.99, Sn = poor)
42
How would a CT be beneficial as an imaging technique for the CS?
CT would show the relationship of bone to neural canal in transverse plane
43
How would an MRI be beneficial as an imaging technique for the CS?
Visualization of spinal cord and soft tissues
44
How would an Myelogram be beneficial as an imaging technique for the CS?
visualization of spinal cord and nerve roots (w. contrast injected into subarachnoid space)
45
What imaging technique would you use to get a good image of a disc?
Discogram (inject contrast material into disc)
46
Review Table 4: Neck Pain impairment/function-based fx, exam, and intervention recommended classification criteria!!
Good job!
47
What are expected sxs of a pt with Neck Pain w/ MOBILITY DEFICITS?
- Unilat neck pn - lim neck motion - onset of sxs often linked to recent unguarded/awk mvmt/position - assoc (referred) UE pn (may be present)
48
What are expected sxs of a pt with Neck Pain w/ HA?
- noncontinuous, unilat neck pn and assoc (referred) HA - HA is precipitated/aggravated by neck mvmts/sustained postures
49
What are expected sxs of a pt with Neck Pain w/ MOVEMENT COORDINATION IMPAIRMENTS?
- neck pn & assoc (referred) UE pn - sxs often linked to a precipitating trauma/whiplash & may be present for an extended period of time
50
What are expected sxs of a pt with Neck Pain w/ RADIATING PN?
- neck pn w/ assoc radiating (narrow band of lancinating) pn in involved UE - UE paresthesia, numbness, weakness (may be present)
51
Which cervical discs have the GREATEST occurrence of disc disease?
C6/7: 60-70% (C7)
52
What are Cloward's areas?
- Irritation of ant cervical disc results in interscapular pn (location of pn is relted to level of disc irritation
53
C6/7 (C7) has the greatest occurrence of disc disease, based off of cloward's areas, if a pt has irritation of the anterior cervical disc at this level, where would they feel pain?
Interscapular area: at the level of T7 and the inf angle of scapula
54
what is the most serious consequence of cervical spondylosis?
cervical spondylitic myelopathy
55
What are sxs of cervical spondylitic myelopathy?

According to the McKenzie Classification, what are the 3 syndromes of mechanical pain?
1. Postural syndrome 2. Dysfunction syndrome 3. Derangement syndrome
59
Postural syndrome is one of the 3 syndromes of mechanical pn according to the McKenzie Classification. What is it and what are it's characteristics?
= proposed as caused by mech deformation or vascular insufficiency of normal tissue as a result of sustained loading - gradual onset, dull, symmetric pn - full cervical AROM - no referred pn - neck pn w/ sustained end range positions may take > 15 min
60
Dysfunction syndrome is one of the 3 syndromes of mechanical pn according to the McKenzie Classification. What is it and what are it's characteristics?
= caused by mech deformation or vascular insufficiency of abnormal tissue (shortened & fibrosed or lengthened) - intermittent neck pn - loss of cervical AROM - neck pn at end-range - no arm pn
61
Derangement is one of the 3 syndromes of mechanical pn according to the McKenzie Classification. What is it and what are it's characteristics?
= (disc primarily) caused by internal disruption or displacement of tissues (thought to be disc related) - loss of cervical AROM - constant neck pn - pn radiated into shoulder/arm - neck/arm pn affected by repeated movement (peripheralization: pn inc in limb, centralization: pn lessens in limb)
62
What is the most common CS postural impairment?
FHP
63
what is the effect os FHP on the CS & mm activity?
1. increased facet loading 2. slight ext of upper CS: forward gaze 3. inc post cervical mm activity

1. heat 2. flexibility
66
what is whiplash?
an abnormal acceleration deceleration of head beck and torso
67
T or F: 20-25% of pts with WAD will become chronic
T
68
What are chronicity prognostic indicators for WAD that have high evidence?
- elevated pain scale & disability ratings -excessive initial self-reported pain intensity (7/10) - extreme disability (NDI >40/100) -low self-efficacy - catastrophizing - lower educational level - reduced cervical ROM -Anxiety -large # of initial sxs
69
T or F: increase sensitivity to cold is assoc w/ ongoing disability after whiplash?

70
What ligament test would you perform first?
sharp-purser
