Using MRI Scans to Evaluate Spinal Manipulation

2014-08-27 03:54:52 | BioPortfolio


Lumbar spinal manipulation, or chiropractic adjusting, is thought to separate the surfaces of the spinal joints and thereby relieve lower back pain. This study will use MRI scans to evaluate the spinal joints before and after spinal manipulation.


Zygapophysial joints, better known as facet or “Z” joints, are located on the back (posterior) of the spine on each side of the vertebrae where it overlaps the neighboring vertebrae. Z joints provide stability and allow the spine to bend and twist. Adhesions in the Z joints may develop following hypomobility of vertebrae. These adhesions may be alleviated by separation (gapping) of the Z joints.

Side posture adjusting (spinal manipulation) is thought by many to gap the Z joints, yet no measurable differences of the Z joints before and after spinal manipulation have ever been published. This study will evaluate gapping of the L3/L4, L4/L5, and L5/S1 Z joints by taking measurements directly from MRI scans of the Z joints before and during positioning for a side posture adjustment, and before and after side posture adjusting.

Health volunteers will be randomly assigned to one of four groups: 1) neutral position followed by side posture positioning (trunk rotated to the volunteer’s right); 2) neutral position followed by side posture spinal adjusting followed by neutral positioning; 3) neutral position followed by side posture spinal adjusting, followed by side posture positioning; and 4) neutral position followed by neutral position (control group). MRI scans will be taken with the volunteers in the original neutral position and in the final position (either second neutral position or side posture positioning).

Medical and Biotech [MESH] Definitions

The anterior concavity in the curvature of the lumbar and cervical spine as viewed from the side. The term usually refers to abnormally increased curvature (hollow back, saddle back, swayback). It does not include lordosis as normal mating posture in certain animals ( = POSTURE + SEX BEHAVIOR, ANIMAL).

A condition of persistent pain and discomfort in the BACK and the LEG following lumbar surgery, often seen in patients enrolled in pain centers.

Acute or chronic pain in the lumbar or sacral regions, which may be associated with musculo-ligamentous SPRAINS AND STRAINS; INTERVERTEBRAL DISK DISPLACEMENT; and other conditions.

Inflammation of the SACROILIAC JOINT. It is characterized by lower back pain, especially upon walking, fever, UVEITIS; PSORIASIS; and decreased range of motion. Many factors are associated with and cause sacroiliitis including infection; injury to spine, lower back, and pelvis; DEGENERATIVE ARTHRITIS; and pregnancy.

The lumbar and sacral plexuses taken together. The fibers of the lumbosacral plexus originate in the lumbar and upper sacral spinal cord (L1 to S3) and innervate the lower extremities.
