When the SI joints are also involved, low back pain occurs. The examination of the pelvic joints involves a number of otion-palpation maneuvers, which have been previously described in detail. Studies have shown high interobserver consistency among trained examiners in evaluating pelvic joints. Pushing and releasing to ballot the joint will cause pain if the joints are dysfunctional or inflamed. MRI may thus be an additional diagnostic tool.
Treatment involves manipulative techniques that are easily learned.
Occasionally, repeat manipulations may be necessary until the joint stabilizes and the surrounding soft tissues tighten. A home program of directed stretching and strengthening is also advisable. An excellent discussion of treatment principles for pelvic joint dysfunctions is extensively covered elsewhere. Expeditious treatment improves the clinical outcome. Delay of diagnosis allows the joint to stay in a dysfunctional position, prolonging the attended stretch of supporting ligaments, muscles, and tendons.
