Paper Abstract

Locomotor diseases is a wide range of about 450 different illnesses with all different pathologies, clinical and prognostic features and response to treatment. No single method will be able to cover the whole spectrum of local and systemic signs and symptoms. Nevertheless there is a need for objective measurements at the site of disease: clinical examination is often enough depending from subjective estimations and personal experiance of the clinician. Laboratory tests only show the systemic effect of the disease, like inflammation. X-rays are restricted to the detection of structural changes appearing late during the pathological process, even when using different techniques. Here IRT offers several advantages to the clinician as well as to the patient. As a non invasive method it monitors the course of disease at the anatomic site of pathology. Quantitative figures calculated from the thermogram,either taken at steady-state or during dynamic tests, are essential for differential diagnosis and follow-up. Advanced IRT camera systems fulfill all requirements set up for medical thermography recently by the National Bureau of Standards. Although, the user should check his system daily with regard to precision of absolute temperature measurements. Standardisation of recording technique is essential as well,to get reliable results. Ambient conditions must be adapted to the locomotor disease pathology under study. Advanced IRT systems , e.g. ZEISS-IKOTHERM, together with image processing capability and special software, e.g. THERMOTOM package, are valuable tools to the rheumatologist for diagnosing and monitoring locomotor diseases.
