How Is Spinal Stenosis Diagnosed?
The doctor may use a variety of approaches to diagnose spinal stenosis and rule out other conditions. Medical historythe patient tells the doctor details about symptoms and about any injury, condition, or general health problem that might be causing the symptoms. Physical examinationthe doctor (1) examines the patient to determine the extent of limitation of movement, (2) checks for pain or symptoms when the patient hyperextends the spine (bends backwards), and (3) checks for normal neurologic function (for instance, sensation, muscle strength, and reflexes) in the arms and legs. X rayan x-ray beam is passed through the back to produce a two-dimensional picture. An x ray may be done before other tests to look for signs of an injury, tumor, or inherited problem. This test can show the structure of the vertebrae and the outlines of joints, and can detect calcification. MRI (magnetic resonance imaging)energy from a powerful magnet (rather than x rays) produces signals that are detected by
