[Nonspecific low back pain and chronification].

Low back pain is the leading cause of incapacitation and medical rehabilitation. The purpose of this German National Health Care Guideline "Nonspecific low back pain" is to optimize the care of patients with low back pain. This guideline was drawn up by 29 professional societies and organizations. In the case of nonspecific low back pain, a detailed medical history and physical examination should be carried out first, but no further diagnostics unless there are indications of the so-called "red flags". For symptomatic treatment, medicine should be given in low doses, and physical activity should be in the foreground. A physician should act as a point of contact throughout the course of the disease, and the patient must be continuously educated and motivated to have a healthy lifestyle, including regular physical activity.
