Abstract

This study was undertaken to assess the sensitivity and specificity of thermographic diagnosis of unilateral carpal tunnel syndrome in a patient population large enough to permit meaningful statistical analysis. Sixty-one persons with clinical diagnoses of unilateral carpal tunnel syndrome confirmed by electrodiagnostic examination and 40 symptom-free volunteers underwent standard thermographic examinations. The thermographic images were then randomly sorted and interpreted by an experienced physician thermographer. Fifty-seven of the 61 patients with carpal tunnel syndrome were found to have thermographic abnormalities, while only one of the control group was found to have such an abnormality. Individual area sensitivity was highest in the dorsal area, but addition of other regions increased this measure; specificity ranged between 98% and 100%. These findings would appear to confirm the value of thermography in the diagnosis of unilateral carpal tunnel syndrome.
