Spine magazine, a well-respected medical journal, published a study from Texas Woman's University in their January 15, 1999, issue. The report appears to verify what chiropractors have been saying for over 100 years. Although the study was complex, researchers tested something known as the "H-Reflex" to measure the effect of pressure on spinal nerves. What they found was that pressure on spinal nerves, (chiropractors have referred to this as subluxation), causes measurable changes in the H-reflex. This shows a change in nerve function due to pressure on nerves.
Although this study is good, it only serves to verify prior chiropractic research on subluxation. In two separate studies, it was shown that as little as 10 to 45 millimeters of mercury pressure, (the weight of a coin on your hand), placed on the nerve root was enough to change the nerve impulses by 40 to 60 percent in minutes. This kind of research is good, but it only serves to verify what chiropractic patients have known for over 100 years. Chiropractic Works!
