Thermography reveals the skin temperature changes in various condition of body. The skin temperature is varied according to subcutaneous blood flow under the control of autonomic nervous system. In radiculopathy discogenic pain causes the change in sympathetic function of the nerve root and changes skin temperature along the nerve root. Digital infracred thermographic imagin system has beed used for diagnosis of radiculopathy without hazard or discomfort and can measure the temperature change due to discogenic pain objectively. Authors analyzed pre- and postoperative thermographic imagings in 931 cases of lumbar disc herniation and the types of thermographic imaging and thermatomes of each compressed nerve root were analyzed. Thermograpy showed high sensitivity in diagnosis of disc herniation and showed high validity in evaluation of postoperative course. Thermography in useful for diagnosis and follow up of postoperative clinical course.
Key Words: Thermography; Radiculopathy; Sensitivity; Validity
