In this study 2780 patients with mechanical low-back pain referred themselves to 60 doctors of chiropractic and 111 medical doctors. These cases were reviewed for effectiveness of care and for costs. One of the articles noted that back pain care in the United States alone is estimated to reach $48 billion this year, and, at any given time, 80 percent of the U.S. population suffers from back pain.

The results of the study showed several interesting facts. With regards to the outcomes, the study showed that both the acute and chronic patients showed better outcomes in pain and disability reduction and higher satisfaction with their care after undergoing chiropractic care, as compared to medical care.

The costs of the care for the medical and chiropractic showed different results depending on the usage. Without adding the costs of any over-the-counter drugs, hospitalization, or surgical costs, when you simply compared the costs of in-office chiropractic to in-office medical care, the chiropractic care was slightly more expensive. If you then add in the additional costs for any referrals made by the chiropractor or the medical doctor, the chiropractic care costs for chronic patients were then 16 percent lower than medical care costs.

The authors of the study, noting that the satisfaction for the chiropractic care was higher, and the overall total costs were lower, made a concluding statement urging more chiropractic utilization in the health care system. They stated, “With their mission to increase value and respond to patient preferences, health care organizations and policy makers need to reevaluate the appropriateness of chiropractic as a treatment option for low-back pain.”

Possibly the most impressive statistic was that 73% of those trying chiropractic found it helpful. The reasons given why people said they tried the non-medical care was to control pain, because they heard it helps, because it is safe, because it helped someone they know, and because their prescription medication wasn’t working.

The article noted that serum thiols are primary antioxidants. Higher antioxidant levels can serve as a way of measuring human health status and DNA repair enzyme activity, which has been shown to correlate with lifespan and aging.  In this study researchers measured serum thiol levels in 21 patients, some of these with a variety of health issues or pain, who had undergone short-term chiropractic care.  Researchers also evaluated a group of 25 asymptomatic patients who had undergone long-term chiropractic care. These results were then compared to a control group of 30 people who had not received any chiropractic care.

The study results showed that, as the researchers expected, patients who were in pain had the lowest antioxidant levels.  However, those patients who were under longer term chiropractic care had statistically significant higher antioxidant levels than both the short term patients with pain, as well as those without pain who did not receive chiropractic care.

One of the authors explained, “Going through life, we experience physical, chemical, and emotional stress. These stresses affect the function of the nervous system. We hypothesized that these disturbances in nerve function could affect oxidative stress and DNA repair on a cellular level.”  Kent continued, “Oxidative stress, metabolically generating free radicals, is now a broadly accepted theory of how we age and develop disease.”
