Using MRI Scans to Evaluate Spinal Manipulation Clinical Trials Resources presented on Clinical Trials Search isn't meant to be a substitute for qualified health advice, visits or professional assistance with a real medical. We aren't doctors. Always consult your mD about Using MRI Scans to Evaluate Spinal Manipulation conditions. Clinical Trials Search.org is a website dedicated to listing clinical research studies in human subjects. Using MRI Scans to Evaluate Spinal Manipulation Clinical research trials and Using MRI Scans to Evaluate Spinal Manipulation health trials occur in a lot of of places throughout the United States of America. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically assess the effectivity of new does drugs. The role of the studies / projects is to resolve certain human healthcare questions. Clinical trials are a popular way for doctors, government agencies, and private sector corporations to detect remedies for all varieties of circumstances, such as Using MRI Scans to Evaluate Spinal Manipulation. Using MRI Scans to Evaluate Spinal Manipulation Clinical Trials and other clinical trials allow volunteers to obtain health treatment choices before they are available to the general public. Most times the human subjects recieve professional assistance for free of charge, and every now and again they are paid for their time. Sometimes there is a cost for a Using MRI Scans to Evaluate Spinal Manipulation clinical trial. Human subjects frequently get the finest healthcare available for their Using MRI Scans to Evaluate Spinal Manipulation condition. Risks are a reality, however, and may include extra or frequent physician visits, medical dangers (possibly life-threatening), and/or the treatment being uneffective. Trials are federally governed with strict guidelines to protect clinical trials patients.

Using MRI Scans to Evaluate Spinal Manipulation
For Condition: Lower Back Pain
Status: Completed
Sponsor(s): National Center for Complementary and Alternative Medicine (NCCAM) ,
Synopsis: 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.
Details: 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).
