Infrared thermography can detect joint inflammation and help improving work ergonomics

Infrared thermography can help detect joint inflammation and help improving work ergonomics, according to a recent study. All objects with a temperature above absolute zero emit infrared radiation as a result of the thermal motion of their molecules. Infrared thermography (IRT) is an imaging modality that can be used to detect this thermal radiation. Human skin emits infrared radiation almost like a perfect black body, and IRT is thus well suited for the measurement of skin temperature. However, although the human core temperature may be indicative of several bodily dysfunctions, there is still a lack of scientific evidence about which musculoskeletal diseases or conditions can be diagnosed by evaluating skin surface temperature with IRT. Nonetheless, since it is a non-invasive and straightforward technique, IRT may represent a cost-effective alternative to the more traditional imaging modalities.
