Having adequate mobility through the mid-back, also known as the thoracic spine, is important in preventing pain and dysfunction. The thoracic spine consists of 12 vertebrae that starts at the base of the neck and runs down to the low back.
It covers a large portion of the spine and is meant to be mobile so we can flex forward, extend backward, bend side to side, and rotate left and right.
One of easiest ways to prevent this loss in mobility is to maintain a tall, upright posture when sitting. Slouching accelerates that mobility loss leading to long term pain and dysfunction so start thinking about that posture now!
