Thermography in posttraumatic pain.

Posttraumatic pain is often associated with complex disturbances of the sympathetic nervous system which also controls microcirculation of the skin. Circulatory skin changes are in turn reflected by altered superficial thermal emission, which can be reliably imaged by thermography. Examples of classic thermographic patterns associated with commonly occurring injuries and detected along cutaneous distributions of peripheral nerves or spinal root dermatomes are presented. Thermographic abnormalities may also occur in ondermatomal distributions to involve an entire hand, foot, or extremity as observed in reflex sympathetic dystrophy. Such thermographic findings often appear before skin or roentgenographic changes become manifest and lead to earlier diagnosis. Prompt and more effective treatment, particularly in reflex sympathetic dystrophy, may thereby be initiated so that full blown, difficult to manage, chronic disability may be averted. The diagnosis of malingering may also be strengthened or suspected if thermographic studies together with other examinations are normal.

Contact thermography of spinal root compression syndromes.

A thermographic technique is described that uses cholesteric liquid crystals that change color in response to variations in surface temperature. The crystals are embedded in elastic flexible sheets that conform to the contours of the torso and extremities. The technique is well suited to temperature measurement of individual skin dermatomes and myotomes. Typical heat patterns emanating from the torso and extremities have been observed and correlated with root compression syndromes at low cervical and low lumbosacral levels. The imaging results correlate well with clinical and surgical findings, particularly when the extremity dermatomes are included. The technique objectively documents the subjective complaint of pain and approaches myelography in accuracy. It was in agreement with myelography in 86% of cases and with surgery in 95% of cases. Liquid crystal thermography may, therefore, effectively screen patients of myelography and can complement it in identifying clinically significant abnormalities.
