[Exercise as a treatment for low back pain management].

Low back pain is an illness with various economic and social repercussions since it is one on the most causes of work absence worldwide. When the patient feels pain in the back, there is an uncertainty regarding a possible risk or cause for low back pain; however, diagnosis is not easy, and around 90 % of the cases do not present physical evidence, therefore, the problem is classified as a non-specific low back pain. Treatment includes body movement, because rest weakens the back muscles and causes atrophy; the recommended exercise methods include exercises for the trunk and abdomen muscles mainly, muscular resistance, spinal stability, Pilates, Williams and Mckenzie exercises, Feldenkrais and Alexander techniques, among others.
