Question | Answer |
---|---|
What is included in a treatment plan? | Frequency, duration of initial phase, assessment, technique, modalities, braces and supports, outcome assessment tools, home instruction |
What is treatment frequency based upon? | The severity of the patient’s condition and the patient’s need for care |
What factors affect the frequency and duration of care? | Non-compliance of the patient; severity of the kitchen; age of the patient; length of disability; comorbidity |

What is the 3rd most common condition chiropractors treat after neck and low back pain? | Headaches; patients will take OTC’s for HA before seeing a physician/chiropractor |
What are diagnostic alarms when evaluating headaches? | Begins over age 50; sudden onset; accelerating pattern; new onset in a pt w/ HIV or CA; HA w/ systemic illness; focal neuro S/S of disease; papilloedema |
What happens w/ nociceptors in a HA? | Stimulated by stress, muscular tension, dilated blood vessels, other HA triggers; nociceptors send message to the nerve cells in the brain signaling that part of body hurts |
Why doesn’t stimulation or destruction of the brain produce pain? | Bones of the skull and tissues of the brain itself do not hurt b/c they don’t have pain-sensitive nerve fibers |
What are the 4 categories of primary headaches? | 1. Migraine; 2. Tension-type HA (muscular contraction) MC; 3. Cluster HA (<1%); 4. Miscellaneous |
What is the second most frequent type of primary HA and how are they referred to? | Migraines; referred to as a neurovascular HA b/c it is most likely caused by an interaction b/w blood vessel and nerve abnormalities |
Describe frequency of migraine HAs. | Migraine accounts for 64% of all females and 43% of all males w/ severe HA |
What is the pathophysiology of migraines? | Associated w/ fluctuations in cerebral perfusion; areas of hypo-perfusion preceding the onset of a HA followed by a period of reactive hyper-perfusion and eventual normalization of flow |
Males and females have different frequencies of migraines according to age, what are they? | <10 y/o males have higher frequency but after puberty migraines are more common in females 3:1 |
What is the general rule for migraines? | Typically unilateral and throbbing but can be bilateral and felt anywhere around the head and neck |

What are the criteria for migraine w/o aura? | Must have at least 5 attacks w/: HA lasting 4-72 hours; HA has 2 of unilateral, pulsating, inhibits activities, bothered by physical activity; nausea or photophobia; not related to secondary HA or if present not related to current complaint |
What are motor Sx of migraine HAs? | Hemiparesis, partial paralysis of one side of the body caused by corticobulbar tract lesions; aphasia, impairment of language |
What is the relationship b/w tension and migraine headaches? | Tension HA can lead to a migraine and migraine can lead to tension HA |
What are the types of migraines (3)? | Migraine w/o aura, migraine w/ aura, retinal migraine |
What is an aura? | Scintillating scotomas: MC migraine aura; an absent arc or band of vision w/ shimmering zigzag border and often combined w/ visual hallucinations that can take many shapes |
What is a diagnosis of a migraine based on? | Exclusion; R/O other etiologies using lab and/or radiographs, consider visual field testing w/ visual phenomena, have a heightened sense of concern in pts w/ solely unilateral HA that remain on the same side (should change) |
What is the research w/ migraines and chiropractic? | Not a lot of evidence based research demonstrating the efficacy of chiropractic manipulation in the Tx of migraine and cluster HA |
What is the MC primary HA? | Tension HA; 75% of HA sufferers; typically a steady ache rather than throbbing and on both sides of the head |

What are features of cluster HA? | Rocking back and forth or pacing in the dark; tears streaming from one eye; face contorted in pain |
Who is affected more w/ cluster HA? | Men 6:1; Usually b/w ages 20-50 but can begin early <10 or late >70; women may get attacks after 50, not correlated w/ menses but tend to stop during pregnancy |
What are characteristics of bouts of cluster HA? | clustered in cycles that usually last 4-8 weeks; pain-free remission in 90%; bouts may be as short as a few days or as long as 4 months; later the onset the greater chance of it becoming chronic |
What is the relationship b/w cluster HA and sleep? | Awakened from sleep by pain in ~50% of cases, usually w/in 2 hours of falling asleep; nocturnal attacks associated w/ REM sleep ½ the time in episodic form but rarely in chronic form |
What are the types of pain w/ cluster, migraine and tension HAs? | Cluster: pain in and around one eye; tension: pain is like a band squeezing the head; migraine: pain, nausea and visual changes are typical of classic form |
What are causes of secondary HAs? | HA attributable to head and/or neck trauma; HA attributable to cranial or cervical vascular disorders; disorders of the face and neck, eyes, ears, nose, sinuses, etc (cervicogenic) |

What is somatosensory evoked potential useful for? | Evaluation of myelopathy but not recommended too identify radic |
Why should one use electrodiagnostic studies? | To determine the site of a lesion but does not ID what is causing the entrapment, just the location |
What is amplitude w/ NCV? | The height of the evoked response on the oscilloscope; reflects the size of the response to an electrical stimulus, or the number of conducting fibers and their degree of synchrony |
What is latency w/ NCV? | Measures the time from the stimulus to the onset of the evoked response; calculated measureing the time it takes to send an electrical stimulus from A to B time it takes is measured and called latency in ms |
What is duration w/ NCV? | Measures the time of the action potential in the negative direction along the x-axis |
What is temporal dispersion? | Time the wave is evident on the screen is dependent upon synchrony of the conduction b/w the fastest and slowest conducting nerve fibers |
What can affect conduction velocity in myelinated fibers? | Myelin thickness, internode distance, age of patient, temperature |
What is neuropraxia? | short term, compression of the myelin sheath; amplitude of CMAP or SNAP not affected if there is no axonal loss and all axons are conducting the stimulus |
What is axonotmesis? | axonal loss, nerve sheath intact, regeneration possible; NCV reduced amplitude, motor weakness, longer recovery time, latency not affected since fibers intact |
What is neurotmesis? | complete severing of a nerve bundle |
What is an EMG? | Strictly a motor test, negative w/ neuropraxia, must have axonal loss, evident as early as 7 days w/ root lesions, positive peripheral signs usually after 21 days |
What are evoked potentials? | Strictly sensory; can be used for peripheral nerves or roots |
