Back pain, the pain felt in the low or upper back. Causes of pain in the low and upper back include conditions affecting the bony spine; discs between the vertebrae; ligaments around the spine and discs; spinal inflammation; spinal cord and nerves; muscles; internal organs of the pelvis, chest, and abdomen; tumors; and the skin.

Pilates is a particularly good exercise for many people with back pain as it is designed to strengthen the deep abdominal and pelvic floor muscles, which provide support to the back. Pilates has been found to reduce chronic back pain and the disability associated with back pain.
