How to exercise for rehabilitation of chronic back pain (limited mobility of thoracic spine)?

One of the many causes of back pain is limited mobility of the back, primarily lateral and rotational, thus allowing the scapula and lumbar spine to compensate for more mobility lateral and rotational, causing pain in these areas. Increasing the mobility of the thoracic spine segment, especially lateralization and rotation, can effectively relieve back pain and lumbar pain.
