[Analysis of the location of pain related to sacroiliitis in ankylosing spondylitis].

The characteristics of the pain were investigated in 99 ankylosing spondylitis patients (62 men and 37 women) from 17 to 70 years with various developing stadies of sacroileitis. The analysis of the sacroileitis pain characteristics revealed the dominance of appearing in rest (at night and by day rest) and obligatory morning low back stiffness. The intensity of pain was more severe in women, more dull, located inguinally, in low abdomen and symphysis. The pain propagated on more distant locations (the tight and the leg), shortly or for longer period in one and/or both legs. The provocating factors of intensification and propagation of the pain were commonly meteorologic factors and rest during night and/or day. The evaluation of pain characteristics could be of great benefit in diagnostics of the sacroileitis or ankylosing spondilytis which usually are not concerned with special significance.
