In 2008, the US Army commissioned a study to determine whether Chiropractic Manipulative Therapy (CMT) in addition to Standard Medical Care (SMC) would "decrease pain and increase function for patients with low back pain." The results of this trial suggested that CMT in conjunction with SMC offers a significant advantage for decreasing pain and improving physical functioning when compared with only standard care, for men and women between 18 and 35 years of age with acute Low Back Pain (LBP).

To date there are 62 Chiropractic clinics in Department of Defense facilities and 1 in the US Capital, Washington DC.

The Tricare military health care program is for uniformed service members that includes active duty and retired members of the: U.S. Army, U.S. Air Force, U.S. Navy, U.S. Marine Corps, U.S. Coast Guard, the Commissioned Corps of the U.S. Public Health Service and the Commissioned Corps of the National Oceanic and Atmospheric Association and their families around the world.
