Abstract
The thermographic appearance of a clinically diagnosed case of sacroiliac (SI) syndrome is presented. A diffuse area of increased thermal emission was imaged over the anatomical location of the joint. This pattern is similar to the thermal image seen in rheumatological patients with gross sacroilitis. The thermal image returned to normal (thermal symmetry between SI joints) after a course of manipulation to the dysfunctional joint. Suggestions for future study are given.
