There is no cure for AS. Treatment is centered around patient education and managing symptoms. Because of the inflammation, the first line of treatment is usually non-steroidal anti-inflammatory drugs (NSAIDs).
Physical therapy is a central part of the management program. The patient is set up with a home program of spinal extension exercises, deep breathing, and range of motion exercises. Strength training for core muscles of the trunk are also important. The patient is advised to do these exercises routinely (daily if possible).
More recently, biologic agents called tumor necrosis factor alpha inhibitors (TNF-a inhibitors) have been used with AS. These drugs are very effective in reducing inflammation and preventing flareups. Patients experience decreased pain and increased motion, which results in improved function.
