A research study published in the November 7, 2005 issue of the Journal of Vertebral Subluxation Research, showed a positive result in the care of individuals with depression. For the purpose of this study subjects were selected on the basis of being over 18 years of age and having depression noted in their medical history file. Fifteen participants completed the study and were used in determining the results.
In the discussion section of the study, it was noted that the concept of chiropractic care’s role in mental health was not a new idea. In fact it was reported that two major chiropractic psychiatric hospitals functioned successfully for nearly thirty years in Davenport, Iowa.
The subjects of this study were given a standardized test known as the Beck Depression Inventory (aka BDI-II) both before and after receiving specific chiropractic care for correction of subluxations. To be consistent, the same process of analysis and techniques of correction were used in correcting the subluxations determined to be present. Before and after x-rays were also used to determine the presence and correction of the subluxations.
The results showed a significant improvement of the average BDI-II scores of the group. Lower BDI-II are considered better than higher scores. The higher the level the more severe the depression. The group as a whole scored a 17 in the BDI-II before chiropractic. After chiropractic care for correction of their subluxations the groups average score improved to 8.
On an individual basis, eleven participants experienced marked improvement, two had minimal improvement while 2 participants scored worse on the follow up test. The researchers noted that this research tested and supported the hypothesis that chiropractic correction of the subluxation complex reduced depressive symptomatology.
The researchers concluded by stating, “This study’s results provide support for the hypothesis that a positive relationship exists between a correction of the occipitoatlantoaxial subluxation complex and a reduction in depressive symptoms in some people.”
