Detailed Description:
A randomized, controlled, single-blind, prospective trial being conducted involving 54 patients with ankylosing spondylitis, selected from outpatient clinics - UNIFESP. They will be randomized in intervention group (n = 27) conduct training for muscle strengthening with the aid of the Swiss ball and in the control group (n = 27) did not undergo any intervention. Eight exercises will be conducted with intent to engage all muscle groups.
