What You Need to Know About Spinal Manipulation: How It Relieves Pain and Restores Movement

Spinal manipulation goes by several names, including spinal manipulation therapy (SMT), chiropractic treatment, chiropractic manipulation, chiropractic adjustment, and spinal adjustment. Most people know it by its audible effect: joint popping, back popping, neck popping. Beyond that sound, the science and clinical rationale behind it are not commonly known, which is unfortunate, because that science is real and understandable.

For spinal manipulation to be effective, there needs to be a spinal joint problem to manipulate. Spinal joints that are not moving in the right amounts or in the right direction are described as “fixated,” meaning the joint is tight and stuck. It is the job of the muscles to move the joint and the job of the joint to move, and when that relationship is not working correctly, pain and stiffness result. A newly stuck joint typically brings inflammation at that level of the spine, pain with attempted motion or pressure, and changes in how the muscles support the joint.

The longer a joint stays stuck, the more the problem can build. When spinal motion has been restricted for months or years, joint degeneration (arthritis), adhesion of the joint capsule, and atrophy of the supporting muscles can eventually occur. That progression is why identifying a stuck joint matters, and why the joint itself is the focus of spinal manipulation.
