I found this article timely not only for those who suffer from AS but for all people. Our daily activities, including those of our young people, are increasingly putting us in forward bending positions, such as driving, computer work, texting and heavy backpack carrying. This continued flexion of our spine is compromising our body in many ways, including but not limited to reducing our lung capacity. It is important to find ways to bend backwards daily. We know many who have utilized furniture, exercise balls and yoga. The best way we know how is a tool we developed, as Doctors of Chiropractic, for extension [bending backwards] in a relaxed and fully supported manner.
