Internal Carotid Artery Strains During High-Speed, Low-Amplitude Spinal Manipulations of the Neck

Journal of Manipulative and Physiological Therapeutics
Researchers from the University of Calgary in Alberta used six fresh, unembalmed cadaveric specimens to quantify the strains applied to the internal carotid artery (ICA) during neck spinal manipulative therapy. The researchers also evaluated the range of motion (ROM) and diagnostic testing of the head and neck. As experienced chiropractors performed cervical spinal manipulation, peak and average strains on the Convocation’s ICA were measured with sonomicrometry. Those measurements were compared with the measurements of corresponding strains during ROM and diagnostic testing of the head and neck. The Canadian researchers found that peak and average strains of the ICA were significantly smaller during cervical spinal manipulative therapy than ROM and diagnostic testing. The authors concluded that cervical spinal manipulative therapy as performed by trained clinicians does not appear to place undue strain on the ICA and, thus, does not seem to be a factor in ICA injuries.
