Diagnostic Selective Blocks Assess structural pain generators and quantify their relative contribution to a patient’s pain. Many lumbar pain syndromes are diagnosed solely by means of diagnostic blocks. Pain provocation through the stimulation of a structure by an anesthetic block, the similarity of the provoked pain to the patient’s normally perceived pain, and the relief of pain by local anesthetic are well-accepted medical diagnostic tools. The data obtained from a block must be congruent with other patient’s data. Previous slide Next slide Back to first slide View graphic version © 1998 Specialty Physicians Alliance.
