title: Structural abnormalities of muscle tissue in ankylosing spondylitis.
abstract: Muscle tissue of patients with ankylosing spondylitis has been studied by means of histology, histochemistry and electron microscopy and has been shown to be grossly abnormal. The underlying basis of the muscle changes is probably neuropathic and we believe that these changes form part of the over-all pathology of this disease.
