JOINT COUNCIL OF STATE NEUROSURGICAL SOCIETIES of the AMERICAN ASSOCIATION OF NEUROLOGICAL SURGEONS and the CONGRESS OF NEUROLOGICAL SURGEONS Neurological clinical procedure review; Thermography Lyle Leibrook, M.D. AVAILABE PROOF OF EFFICACY: Evidence of prospective studies. Prospective studies have shown the excellent sensitivity and good correlation of thermography with other imaging methods. A high correlation of 84% has been demonstrated in studies comparing thermography and CT scanning of patients with low back pain and sciatica. Surgical treatment has also shown similar high rates of sensitivity. A large study of 805 patients with upper and low back pain confirm good correlation between thermographic evaluation and myelography, CAT scanning and EMG. The two objective tests for documentation of sensory radiculopathy, thermography and somatosensory cortical evoked potential's, show equal sensitivity in the diagnosis of clinical lumbosacral radiculopathy. SAFETY: The procedure is totally non-invasive and does not involve ionising radiation. It is without patient risk. CONCLUSION OF REVlEW: Thermography is a safe and effective means for evaluation of vasomotor instability due to irritation or injury of spinal roots, nerves or sympathetic fibres. It is to be considered an adjunctive test and not solely diagnostic except in cases of reflex sympathetic dystrophy. While one cannot extend the technique of thermography to indicate the central phenomena of perception of pain, it is useful in detecting associated vasomotor instability and complex pain states associated with arthritis, soft tissue injuries, low back disease or reflex sympathetic dystrophy and does provide objective data to identify dysfunction in roots that are irritated in the lumbar spine, peripheral nerves that are irritated, and damage to the sympathetic nervous system.
