<qa>  What is the name of the team that treats patients with persistent low back pain?At the Back Center Copenhagen, patients with persistent low back pain caused by lumbar disc herniation and spinal stenosis are treated by a multidisciplinary team comprising rheumatologists, physiotherapists, chiropractors, and social workers according to current guidelines.
