Low Back Pain

Chronic low back pain may be caused by many different sources. It may start from diseases, injuries or stresses to many different structures including bones, muscles, ligaments, joints, nerves or the spinal cord. The affected structure will send a signal through nerve endings, up the spinal cord and into the brain where it registers as pain. Many different theories try to explain chronic pain. The exact mechanism is not completely understood. In general, it is believed that the nerve pathways that carry the pain signals from the nerve endings through the spinal cord and to the brain may become sensitized. Sensitization of these pathways may increase the perceived pain out of proportion to the source of the pain. Stimuli that ordinarily are not perceived as painful, such as light touch, can be amplified or changed by these sensitized pathways and experienced as pain. Sometimes, even after the original injury or disease process has healed, sensitized pathways continue to send signals to the brain. These signals feel just as real as and sometimes worse than the pain caused by the original injury or disease process. A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
