Chiropractic care naturally reduces the stress on the muscles, allowing them to loosen and this also reduces the pressure on the bones. Many sicknesses can be treated with chiropractic. I believe in chiropractic treatment as it is really helping my friend. Chiropractic back pain treatment is effective like conventional medicine in relieving pain.

Internal forces sustained by the vertebral artery during spinal manipulative therapy☆

Abstract
Background: Spinal manipulative therapy (SMT) has been established as a clinically effective modality for the management of several musculoskeletal disorders. One major issue with the use of SMT is its safety, especially with respect to neck manipulation and the risk of stroke in the vertebrobasilar system. Objectives: Our objectives were to quantify the strains and forces sustained by the vertebral artery (VA) in situ during SMT. Study Design: This was a cadaveric study. Methods: Six VAs were obtained from 5 unembalmed postrigor cadavers. The cephalad/distal (C0-C1) and caudad/proximal (C6-subclavian artery) loops of the VA were carefully exposed and instrumented with a pair of piezoelectric ultrasonographic crystals. The strains between each crystal pair were recorded during range of motion testing and diagnostic tests and during a variety of SMT procedures. The VA was then dissected free and strained on a materials testing machine until mechanical failure occurred. Results: SMT performed on the contralateral side of the cervical spine resulted in an average strain of 6.2% ± 1.3% to the distal (C0-C1) loop of the VA and a 2.1% ± 0.4% strain to the proximal (C6) loop. These values were similar to or lower than the strains recorded during diagnostic and range of motion testing. Failure testing demonstrated that the VAs could be stretched to 139% to 162% of their resting length before mechanical failure occurred. Therefore the strains sustained by the VA during SMT represent approximately one ninth of the strain at mechanical failure. Conclusions: SMT resulted in strains to the VA that were almost an order of magnitude lower than the strains required to mechanically disrupt it. We conclude that under normal circumstances, a single typical (high-velocity/low-amplitude) SMT thrust is very unlikely to mechanically disrupt the VA. (J Manipulative Physiol Ther 2002;25:504-10)

A groundbreaking study on vertebral artery dissection (VAD) and stroke following chiropractic office visits is pending publication in Spine and the European Spine Journal. The study, conducted as part of the Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders, looked at the association between chiropractic office visits and the incidence of vertebral artery strokes. “Current research suggests that dissections are probably multifactorial in origin,” said Task Force President Scott Haldeman, DC, MD, PhD. “They appear to occur in a person with a genetic predisposition to arterial dissection. They also appear to require a second factor such as viral infection or possibly estrogen.

According to the study authors, their findings suggest that the risk of suffering a stroke following a chiropractic treatment might be due to the fact that a VAD is already in progress prior to the chiropractic adjustment. The dissection results in neck pain that brings the patient to the chiropractor’s office seeking relief.

The authors also documented only a handful of stroke cases following chiropractic cervical manipulation in a massive study population spanning nearly 100,000,000 person-years. Even more impressive, the data suggest that while spinal manipulation may increase the risk of an embolism in those with a VAD in progress, which can then lead to a stroke, the association between the stroke and the office visit was no higher in patients who seek the care of a chiropractor than in patients who seek the care of a general physician.

Bottom line Dr. Kevin, educate yourself….the empirical evidence will set you free!

Instead of a carotid artery dissection at the chiro you might actually get a "happy ending" at the massage parlor. Yeah.

I advise patients to go the "traditional" route first, many need to hear those words.
