“…125,126,131,[144][145][146][147] A case series using arteriography displayed partially obstructed blood flow through the contralateral VA at C1 to C2 during head rotation in patients with suspected vertebrobasilar artery ischemia. 146,147 Subsequent studies using duplex sonography have shown no significant change in blood flow in the VA during rotation, 126 simulated manipulation position, 125 and nonthrust manipulation. 131 One study also looked at blood flow in the ICA during simulated manipulation position and found no significant changes in blood flow in a healthy ICA.…”

“…123 Researchers have analyzed biomechanics of the cervical spine during spinal manipulation to determine whether manipulation may cause CD. [124][125][126][127][128][129][130][131] The cervical spine is made up of 7 vertebral bodies and is divided into 4 anatomic sections: the atlas, the axis, the root (C2-C3 junction), and the column (C3-C7). 132 Movements of the cervical spine, including flexion, extension, rotation, and lateral flexion, are dependent on the orientation of the joint facets and are further restricted by muscles and ligaments surrounding the cervical vertebrae.…”

3155Purpose-Cervical artery dissections (CDs) are among the most common causes of stroke in young and middle-aged adults.The aim of this scientific statement is to review the current state of evidence on the diagnosis and management of CDs and their statistical association with cervical manipulative therapy (CMT). In some forms of CMT, a high or low amplitude thrust is applied to the cervical spine by a healthcare professional. Methods-Members of the writing group were appointed by the American Heart Association Stroke Council's Scientific Statements Oversight Committee and the American Heart Association's Manuscript Oversight Committee. Members were assigned topics relevant to their areas of expertise and reviewed appropriate literature, references to published clinical and epidemiology studies, morbidity and mortality reports, clinical and public health guidelines, authoritative statements, personal files, and expert opinion to summarize existing evidence and to indicate gaps in current knowledge. Results-Patients with CD may present with unilateral headaches, posterior cervical pain, or cerebral or retinal ischemia (transient ischemic or strokes) attributable mainly to artery-artery embolism, CD cranial nerve palsies, oculosympathetic palsy, or pulsatile tinnitus. Diagnosis of CD depends on a thorough history, physical examination, and targeted ancillary investigations. Although the role of trivial trauma is debatable, mechanical forces can lead to intimal injuries of the vertebral arteries and internal carotid arteries and result in CD. Disability levels vary among CD patients with many having good outcomes, but serious neurological sequelae can occur. No evidence-based guidelines are currently available to endorse best management strategies for CDs. Antiplatelet and anticoagulant treatments are both used for prevention of local thrombus and secondary embolism. Case-control and other articles have suggested an epidemiologic association between CD, particularly vertebral artery dissection, and CMT. It is unclear whether this is due to lack of recognition of preexisting CD in these patients or due to trauma caused by CMT. Ultrasonography, computed tomographic angiography, and magnetic resonance imaging with magnetic resonance angiography are useful in the diagnosis of CD. Follow-up neuroimaging is preferentially done with noninvasive modalities, but we suggest that no single test should be seen as the gold standard.

“…It is at this level that much of the rotation of the cervical spine takes place (Kapandji, 1987;Soames, 1994) where the vertebral artery is more prone to compress and stretch without being damaged but excess of compression or stretch can also cause damage of the artery. (Haynes and Milne, 2001;Thiel 1991). However, it is now generally agreed that the natural tortuosity of the artery between the first two vertebrae allows the vessel to stretch without damage during normal rotation of the cervical spine .Also according to Rivett (2004), vertebral arteries are important entity during manual therapy because of its vulnerability of getting stressed in its torturous course in the cervical spine.…”

Aim: To investigate the blood flow of vertebral artery at c1-c2 region during manual traction -Mulligan. Method: The focus of the present study is measuring haemodynamic parameters including peak systolic velocity (PSv) and end diastolic velocity (EDv) of vertebral arteries at the sub occipital region of cervical spine in neutral positioning and whether there is change in the hemodynamic parameters during c1-c2 manual traction (mulligan) using Doppler ultrasonography in normal individual mean age 24.68 + 2.03year. Results: The result showed significance difference (p=0.000) in blood flow velocity for PSv and EDv between neutral position and during manual traction for left and right vertebral arteries. Conclusion: This technique had no mechanical effect on vertebral artery rather it has an impact on hemodynamic status of artery and are of great value in increasing the knowledge of the possible treatment protocol related to the blood flow changes with the movements of cervical spine.
