To systematically review the peer-reviewed literature about the reliability and validity of chiropractic tests used to determine the need for spinal manipulative therapy of the lumbo-pelvic spine, taking into account the quality of the studies, the Nordic Institute for Chiropractic and Clinical Biomechanics in Denmark, selected previous studies pertaining to intraexaminer reliability, interexaminer reliability, and/or validity of chiropractic evaluation of the lumbo-pelvic spine to assess. The Nordic Institute for Chiropractic and Clinical Biomechanics concluded that the detection of the manipulative lesion in the lumbo-pelvic spine depends on valid and reliable tests. Because such tests have not been established, the presence of the manipulative lesion remains hypothetical and great effort is needed to develop, establish and enforce valid and reliable test procedures.
