Computerised temperature assessments showed statistically significant side to side temperature differences when 17 active tennis elbows were compared with the opposite normal elbows for spot temperatures, proximal and distal forearm gradients. Similar temperature assessments in 18 bilateral tennis elbows compared with 17 normal elbows showed significant temperature differences for elbow spot temperatures and distal forearm gradients, but not for proximal gradients.
Sixty-five cases of chronic low back pain were studied. Infrared thermography (IRT) was abnormal in 92%, magnetic resonance imaging (MRI) in 89%, computerized tomography (CT) in 87% and myelography in 80%. IRT correlated with MRI in 94% of cases, and with CT in 87% of cases. Of 22 MRI positive disc and root cases, 21 (95%) had significant leg abnormalities on IRT. All 19 cases with radicular involvement on CT and all 18 with radicular involvement on myelography demonstrated significant leg changes on IRT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
