Q

What is upper crossed syndrome?

A

Overactive tight neck extensors, inhibited or weak middle and lower traps, rhomboids, serratus anterior. This will produce elevation and protraction of the shoulders, winging of the scapula and protraction of the head.

Q

A

Headaches usually resolves or improves within 3 days of a high-dose of steroid treatment.

83
Q

What makes a headache a medication-overuse headache?

A

headaches greater than or equal to 15 days a month that result from frequent use of medications taken to alleviate headaches, and they resolve to normal headache pattern within 2 months after discontinuation of meds.

84
Q

Medication-overuse headaches are the most common cause of what?

A

Migraine-like and mixed migraine-like and tension-type-like headaches occuring 15 days or more per month.

85
Q

Name the things that are potential neurologic causes of headaches?

A

intracranial mass lesion, cerebrovascular disease, subarachnoid hemorrhage, meningeal infections, lumbar puncture (spinal tap).

86
Q

What is the most commonly proposed and reported serious side effect of cervical manipulation?

A

Vertebrobasilar complications.

87
Q

What is CVA, VBA, VBI, VBS, CAD?

A

CVA- cerebrovascular accident. VBA- vertebrobasilar accident, VBI- vertebrobasilar ischemia, VBS- Vertebrobasilar stroke, CAD- Cervical artery dissection.

88
Q

What are the proposed effects of pathophysicology of vertebrobasilar complications?

A

Trauma to arterial wall —> vasospasm or frank damage —-> flood flow changes —–> cascade mechanism —-> dislodged thrombus which becomes an embolus —-> brain stem or cerebellar infarct.

89
Q

What part of the vertebral artery is most susceptible?

A

C1-C2 segment due to movement/position.

90
Q

If there is a vasomotor response and arterial vasospams to the vertebral artery what can happen?

A
  1. May last for only a short period with temoprary symptoms. 2. may produce a persistent constriction reduction in blood supply producing ischemia this could also lead to stagnation of blood flow producing a clot.
91
Q

What are the 2 outcomes of injury to the arterial wall?

A
  1. Normal repair with no further problems. 2. Thrombus formation, possible embolus, infarct at the endpoint of the blood vessel.
92
Q

What is wallenburg’s syndrome?

A

Infarct in the distribution of the PICA (posteroinferior cerebellar artery). The findings are assoicated with structures innervated by the crainial nerves.

93
Q

What is locked-in syndrome?

A

basilar artery occlusion that leaves patient with only vertical ocular mobility and blinking. AKA the corpse with the living eyes.

94
Q

The vertebral artery is compromised on the ______ _______ the neck rotation.

A

side opposite.

95
Q

What type of people are more susecptible to flow reduction due to head rotation?

A

Persons who have had a prior vascular injury.

96
Q

What happened to most people who experienced decreased vertebral artery blood flow?

A

They did not exhibit signs or symptoms of neurologic compromise.

97
Q

What are the 4 possible scenarios whereby vascular injury and CSMT may be related?

A

The four C’s; Catastrophic, Congenital, Cumulative, Coincidental.

98
Q

Can forces produced by CSMT physically injure the artery?

A

yes.

99
Q

Symons and herzog’s study showed that it was not possible to produce mechanical failure of the vertebral artery, but what were some of the limitations to the study?

A

Most common VA dissection site not measured, ipsilateral rotation adjustments were used not contralateral, they used old cadavers with decreased ROM, Arteries are different in cadavers (not pressurized and other stuff).

100
Q

One study showed that loads on the neck during normla CSMT were similar to what?

A

A low velocity rear end accident and these are not associated with VA dissections.

101
Q

Of the 198 cases studied where patients had a VA disection after chiropractic treatment when did the VA dissection occur?

A

63%- immediately during SMT, the rest of the % are spread out between 6%-9% and happened within minutes- up to 24 hours or more after.

102
Q

An ontario study (case-control) found people under age 45 were _____ times more likely to have seen a chiropractor within one week prior to the stroke.

A

five.

103
Q

There is a lot of temporal relationship seen with CSMT and stroke what is the problem with this relationship?

A

Temporal relationship alone is inadequate to establish causality.

104
Q

Explaine congenital development of a VA dissection?

A

Genetic predisopsition is necessary and needs to be triggered by risk factors, environmental exposure, with or without trauma for CAD to occur.

105
Q

Is there any evidence to show a cumulative effect from CSMT on VA dissections?

A

No, but there is no evidence to show it is not associated.

106
Q

What is the prevelance of postmanipulation dissection and occlusion, and what is the prevelence of spontaneous cases?

A

Postmanipulation- 31%. Spontaneous- 44%.

107
Q

Why might it seem like CSMT is associated with VA dissections?

A
