The Chiropractic adjustment cannot cause a stroke.

ICA – Internal Carotid Artery – damage to this vessel can cause a stroke

SMT – Spinal Manipulative Therapy – A Chiropractic Adjustment

 

“The researchers therefore conclude that “cervical SMT, as performed by the trained doctors of chiropractic in this study, did not appear to place undue strain on the ICA and thus does not seem to be a factor in ICA injuries.”

Abstract:
Study Design. Population-based, case-control and case-crossover study.

Objective. To investigate associations between chiropractic visits and vertebrobasilar artery (VBA) stroke and to contrast this with primary care physician (PCP) visits and VBA stroke.

Summary of Background Data. Chiropractic care is popular for neck pain and headache, but may increase the risk for VBA dissection and stroke. Neck pain and headache are common symptoms of VBA dissection, which commonly precedes VBA stroke.

Methods. Cases included eligible incident VBA strokes admitted to Ontario hospitals from April 1, 1993 to March 31, 2002. Four controls were age and gender matched to each case. Case and control exposures to chiropractors and PCPs were determined from health billing records in the year before the stroke date. In the case-crossover analysis, cases acted as their own controls.

Results. There were 818 VBA strokes hospitalized in a population of more than 100 million person-years. In those aged <45 years, cases were about three times more likely to see a chiropractor or a PCP before their stroke than controls. Results were similar in the case control and case crossover analyses. There was no increased association between chiropractic visits and VBA stroke in those older than 45 years. Positive associations were found between PCP visits and VBA stroke in all age groups. Practitioner visits billed for headache and neck complaints were highly associated with subsequent VBA stroke.

Conclusion. VBA stroke is a very rare event in the population. The increased risks of VBA stroke associated with chiropractic and PCP visits is likely due to patients with headache and neck pain from VBA dissection seeking care before their stroke. We found no evidence of excess risk of VBA stroke associated chiropractic care compared to primary care.

Garlic and your heart

Garlic & Your Heart

A new study just released in the Oct. 16th , 2007 issue of the prestigious medical journal, Proceedings of the National Academy of Sciences shows that garlic causes red blood cells to release hydrogen sulfide in the body thereby causing blood vessels to relax. 

When blood vessels relax, they become larger and are able to carry more blood and more oxygen to the brain and other important parts of the body.  Blood pressure also comes down when blood vessels relax. It is well known that high blood pressure is a major risk factor for heart disease, so this newly discovered health benefit of garlic, once again, is an example of modern day researchers confirming the wisdom of the ancients.  Garlic has been used for medicinal purposes throughout all of recorded history.

The lead researcher is Biology professor David Kraus from the University of Alabama. He said that there is also another study in progress that shows “sulfide can protect from cardiovascular damage during a heart attack, it can alleviate various sorts of inflammation, and it can reduce platelet aggregation that would cause a blood clot to form”.

When you eat garlic, your body metabolizes garlic’s active ingredient, allicin, and produces hydrogen sulphide. The hydrogen sulphide then signals your blood vessels to relax, increasing blood flow, reducing blood pressure and supporting heart health.

Have you had a serving of garlic today?
