In the meantime, this new understanding of cold stress should improve efforts to treat and rehabilitate rescued manatees with the syndrome.

Eventually, a patient's vertebrae can fuse together, causing complete loss of motion and a stooped-over posture. Ankylosing spondylitis affects about 350,000 people in the United States.
