Arthritis is degeneration of a joint or multiple joints. Arthritis is a result of an injury to a joint, or from overuse of a joint. In some cases, arthritis is an autoimmune disease that focuses on the joints (rheumatoid, psoriatic, etc). With arthritis, spinal ligaments become shortened, losing their elasticity resulting in closing down the joint space.The best practice to help relieve arthritis pain is to restore proper joint motion. In other words, increase the flexibility of that joint.PurePosture helps arthritis in the spine by lengthening spinal ligaments allowing for proper motion.
