Serious side effects seem rare and are generally documented as case reports, case series or retrospective studies, making it difficult to quantify their occurrence or establish causality. However, there have been reports of serious side effects that may have been followed by manual spine treatments in both children and adults . A greater number of evidence, in the form of case control studies, indicates a link between chiropractic visits or spinal manipulation and fluid artery stroke in younger adults, but also suggests that this is not a causal relationship. There are significant gaps in the literature regarding the relationship between manual spinal care and all other reported serious adverse reactions.
In a study of 203 professional manual medicine professionals in Switzerland, Dvorak found a percentage of one serious complication per 400,000 cervical manipulations, without any reported death, among approximately 1.5 million cervical manipulations. Jaskoviak reported approximately 5 million cervical manipulations to the National College of Chiropractic Clinic in Chicago from 1965 to 1980, without a single case of a fluid artery stroke or serious injury. The chiropractor should be well informed about their medical history, including ongoing medical conditions, current medications, traumatic / surgical history and lifestyle factors.
That study showed that chiropractic treatment and neck manipulations can be fatal and cause vascular accidents. US News and World Report summarized many of the risks associated with chiropractor care. These hazards include an increased risk of stroke for patients who received neck adjustment from a chiropractor and an osteopathic physician. “High speed neck manipulations,” said doctors at the American Heart Association, can be particularly dangerous.
Half were randomized to receive regular care (including medicines, self-care and physiotherapy), while the other half were regularly cared for plus up to 12 chiropractic treatments. Insufficient reporting of the adverse effects of a medical intervention was unethical, said Edzard Ernst, professor of complementary medicine at the Peninsula School of Medicine, University of Exeter, who conducted the latest analysis. This allowed chiropractors to give a false positive view of the safety of their treatments, he said. Cagnie et al. invited 59 Belgian physiotherapists to recruit a total of 465 new patients treated with spinal manipulation.42 All patients were then asked to complete a questionnaire on side effects. 61% of all patients reported at least one side effect, most of which were mild and transient, such as headache (20%), stiffness (20%), local discomfort (15%), radiant discomfort (12%) and fatigue ( 12%).
Doctors must take up the challenge of effectively communicating both the potential benefits and the potential risks of the proposed interventions. With such opposing views, it can be difficult for doctors to understand what the existing literature does and does not tell about the risks. While there are systematic assessments for some specific questions about healthcare risks, there has not been a comprehensive assessment to facilitate physicians’ understanding of the problem. The purpose of this scoping assessment Chiropractor Athens is to map the current literature on the safety and risks of manual spinal treatment to identify types and sources of evidence and gaps in research . However, according to a recent article in The New York Times, 15 randomized controlled trials involving more than 1,700 patients showed that spine manipulation improved back pain and function in some patients. And any adverse effects of chiropractic treatment in these studies were considered small, rare and almost never occurred in the treatment of low back pain.
The estimated risk of cohort studies was approximately 0.01% of patients or 0.007% of treatments, when the estimate was based on zero cases of 22,833 patients receiving 42,451 treatments. The estimated risk of RCTs was approximately 0.13% of patients, based on zero cases of 2301 patients. However, while estimates indicate the relative rarity of serious adverse reactions, there are a number of retrospective studies, case reports and systematic case reports that describe serious complications from manual spinal interventions. Another report made a similar comparison in 1,157,475 patients with neck pain of the same age group due to the risk of stroke in the cervical artery after visits to the chiropractic or general practitioner, and concluded that there was little difference . This is consistent with evidence from case control that the cervical artery evaluates after manipulative therapy with the spine, indicating an association only in younger patients . The best research design to assess the association of rare side effects on interventions is the case control study .
Less conservative treatments, such as neck surgery, are also often used for conditions that are very similar to conditions that treat chiropractors with spinal manipulation. There is a 3-4% complication rate for cervical spine surgery and 4,000-10,000 deaths per million neck surgery . If these NCMIC chiropractors are comparable to the national average, they see approximately 120 patient visits per week . Curtis and Bove report that rotating cervical spine modifications make up about 30% of chiropractor visits.
