Brief Summary

After lumbar pain, neck pain is the most common cause of patients needing chiropractic care; the second most common cause of spinal manipulation use (1). Manipulation and mobilization are commonly used by chiropractors, osteopaths and manipulative physiotherapists in the treatment of neck pain. Many studies show that the Activator instrument is also used for this purpose in the chiropractic profession (2) There are several published case reports that relate to neck manipulation to vertebral artery dissection and stroke. The prevailing theory is that the neck extension and / or rotation may damage the vertebral artery in the foramen transversarium, especially at the C1-C2 level (2). However, most cases of extracranial vertebral artery dissection are thought to be spontaneous (3).

In the literature, there have been no studies investigating the effects of instrument-assisted spinal manipulation on vertebrobasilar and internal carotis arteries. the aim of this study to compare the effect of manual and instrumental spinal manipulation on blood flow parameters of vertebrobasilar and internal carotis arteries on healthy persons which have mechanical neck pain and asymptomatic in vertebrobasilar insufficiency test.

GroupInterventionDescription
Manual Chiropractic Spinal ManipulationDoppler UltrasonographyDemographic informations, pain, previous trauma, diseases, current medicine, past surgical operations, pregnancy, smoking use and cervical artery dissection history in family are questioned. Cervical flexion, extension, right and left rotations, right and left lateral flexions are measured by physiotherapist, in sitting position and with goniometer.Upper extremity muscle strength was measured with manual muscle testing in sitting position by physical therapist. The muscles innervated by C4, C5, C6, C7, C8 and T1 cervical nerves were examined bilaterally. Cervical foraminal compression test was used to eliminate cervical root compression.Vertebrobasilar artery was assessed by premanipulative vertebrobasilar insufficiency test.Neck Disability Index was used to evaluate the functional neck status of the participants. After all assessments, participants who were eligible for this study were undertaken Doppler Ultrasonography before and after manual manipulative intervention.
Instrumental Chiropractic Spinal ManipulationDoppler UltrasonographyThe same assessments were applied to determine the eligibility of participants for this study. After all assessments, participants who were eligible for this study were undertaken Doppler Ultrasonography before and after instrumental manipulative intervention.
