Biomedical Musculoskeletal Applications of Infrared Thermal Imaging on Arm and Forearm: A Systematic Review

Infrared thermal imaging (IRT) has been a target of research for biomedical musculoskeletal applications, due to the possible association of the physiological data that it provides, through skin temperature measurement, with pathological states. The aim of this systematic review is to acquaint the outcomes of the biomedical application of IRT in arm and forearm evaluation and its future perspectives of research. During the literature review, 926 articles were identified using the search engines PubMed and Scopus, and 10 articles were retrieved from other sources. After screening the abstracts and applying the eligibility criteria on those which were fully accessible, 33 articles were included in the review. It can be observed that IRT has the potential to provide physiological information on the arm and forearm, showing potential to serve as an aid in various pathologies and health situations. Future studies and challenges are identified and proposed, facilitating the improvement and acceptance of the application of IRT in the assessment of arm and forearm' health status.
