Excerpt from, "Recommendations for the diagnosis of low back pain from the American College of Physicians & the American Pain Society":
-"Clinicians should evaluate patients with persistent low back pain and signs or symptoms of radiculopathy or spinal stenosis with MRI or CT only if they are potential candidates for sugery or epidural steroid injection".
Pretty cool. Even with all this high tech stuff, MD's understand the importance of good postural, static, dynamic, and functional testing. A great text I would recommend to all high school athletic trainers:
"Functional Soft Tissue Evaluation & Treatment by Manual Methods" by Warren Hammer. Dr. Hammer is a chiropractor. They were the first at this manual stuff, and they are still the best.
