Having good posture—head up, shoulders back, rear tucked under—looks great. But good posture also plays a key role in your spine health, helping to prevent additional back and neck pain and even injuries to spinal structures. If you have a spine conditions try to be aware of your posture and make good posture part of your normal routine. Most of us get back pain at some point in our lives. It may be due to a sports-related injury, an accident, or a congenital condition such as scoliosis. But most of the time, upper or lower back pain develops during the course of day-to-day life.
Posture is not simply what happens when you are sitting or standing still—it's also dynamic, and includes your posture when you move. Poor posture may include many elements—rounded shoulders, protruding buttocks and abdomen, overly arched lower back, and the head pushed forward into an exaggerated position. Repetitive activities at work or home, such as sitting at a computer or lifting and carrying, may produce tension and muscle tightness that result in a backache.
