A case study published in the December 18, 2007 issue of the scientific periodical, the Journal of Vertebral Subluxation Research, documented the improvement of a 55-year-old woman who had suffered two automobile accidents. As a result of these accidents, the woman was reporting symptoms of whiplash, loss of range of motion in her right arm, sacroiliac joint pain, shoulder pain, hand pain, numbness and tingling in the arms and legs, and loss of balance. To complicate matters, after her second accident her husband died and she was suffering from depression to the extent that she attempted suicide.

Between the two accidents, some chiropractic care was rendered by a chiropractor other than Andrea B. Ryan, D.C., the author of this case report. That care met with some limited results. After the second accident, the woman's symptoms got worse and she was diagnosed with Post-traumatic stress disorder by her medical doctor.

Nine years after her second accident, she sought chiropractic care from Dr. Ryan, D.C.. She was suffering from a large range of health issues and was on multiple medications. An extensive chiropractic examination was performed and it was concluded that vertebral subluxations were present.

The patient experienced some immediate results. However, most changes occurred over time as care progressed. Overall her dizziness completely resolved, and she was more stable and comfortable when walking, but still required a cane. Her muscle strength in her arms, shoulders, and legs improved and she no longer has pain in her sacroiliac joints.

The author of the study, Andrea B. Ryan, D.C., concluded, "There were three specific goals that the chiropractor and patient set out to achieve before chiropractic care commenced: subluxation reduction, reduction of symptoms, and increased quality of life for the patient. All three goals were accomplished within six months. Based on the results of this case, chiropractic should be considered for patients recovering from traumatic brain injuries."
