  <detailed_description>
    <textblock>
      Ankylosing spondylitis is a chronic, inflammatory rheumatic disease with an unclear etiology&#xD;
      which causes back pain and affects the functionality of axial skeleton. Besides the effect&#xD;
      upon axial skeleton, the disease also affects the peripheral joints. In most patients,&#xD;
      tenuous affection of peripheral joints occurs however, in some others the disease causes&#xD;
      impaired spinal mobility and articular instability. This causes proximal girdle muscles and&#xD;
      trunk muscles of the patients to be exposed to excessively stress and in conclusion&#xD;
      deformities develop. Maximum force generated by a muscle or muscle group directly effects the&#xD;
      physical ability of an individual, and manual muscle dynamometers are used to directly&#xD;
      evaluate the muscle strength. In this manner the investigators aim to evaluate trunk and&#xD;
      proximal girdle muscles' powers in male patients with ankylosing spondylitis and analyze the&#xD;
      correlation between muscle powers, and functionality and disease activity.&#xD;
