“…Another possible explanation could be the SCI condition presented by most of our sample, this population may present cardiovascular limitations, and patients with compromised cardiac function are characterized by a higher extent of vasoconstriction in comparison with healthy [45], which could explain the initial reduction of the T sk . Another characteristic of paraplegic athletes is to have a larger heat storage in the lower body that ends in a diminished ability to reduce their core temperature during the recovery phase [56], that may explain the rise of T sk in the reduced body surface area for active thermoregulation even in brief exercises.…”

h i g h l i g h t sT sk response of wheelchair athletes before and after a propulsion test is presented. The relation between SP and T sk before and after the propulsion test is obtained. Subjects showed lower resting T sk and slower heat dissipation than able-bodied. There were significant negative correlations between the T sk and SP. There were no correlations between the kinematic variables and the shoulder pain. a b s t r a c t Introduction: Wheelchair Users (WCUs) depend on their upper extremities for their daily living. Therefore, it is not unusual to find that shoulder pain (SP) is a problem for WCUs and reduces their participation in sport and leisure activities. Objectives: The aims of this study were 1 -to analyse skin temperature measured by infrared thermography (IRT) before (pre-test), one minute after (post-test) and 10 min after (post-10) the kinematic wheelchair propulsion test (T-CIDIF) of athletic wheelchair users; 2 -to evaluate the relationship between shoulder pain (SP) and Skin Temperature Asymmetry (DT sk ) before and after (pre-test, posttest, post-10) the T-CIDIF, and to relate the SP with the kinematic variables of the T-CIDIF. Participants & interventions/procedure: A volunteer sample of 12 wheelchair athletes completed an exercise test (T-CIDIF) in their own wheelchair. It consisted in a 30-s maximum test performed on two rollers. Two linear transducers connected to the rollers registered the number of propulsions, maximum and mean velocity and power of each arm. SP was assessed with the Wheelchair Users Shoulder Pain Index (WUSPI). Skin temperature (T sk ) of the anterior and posterior upper body was measured before and after the T-CIDIF by using an infrared camera. A total of 26 ROIs were evaluated with respect to the opposite side of the body to identify significant (DT sk ). Results/main outcome measure(s): Significant differences were observed between the T sk of the post-10 and pre-test in 12 ROIs, and between the post-10 and the post-test in most of the ROIs. These differences are attenuated when the DT sk is compared before and after exercise. T sk tends to initially decrease immediately after the test and then significantly increase after 10 min of completing the T-CIDIF. The DT sk vs SP analysis yielded significant inverse relationships (from r = À0.58 to r = À0.71, p < 0.05) in 5 of the 26 ROI. No significant correlations between propulsion variables and SP questionnaire were found. All T-CIDIF variables were significantly correlated with the temperature asymmetries in multiple ROIs (from r = À0.86 to r = À0.58, from p < 0.05 to p < 0.001). Conclusions: These results present indications that high performance wheelchair athletes exhibit similar capacity of heat production than able-bodied. The thermographic data inversely correlates with the SP and the kinematic variables, but the last is not related to SP. This work contributes to improve the understanding about temperature changes in wheelchair athletes during exercise, and could be used to assess the efficacy of various ...

“…Most the studies in which the subjects were exposed to constant and prolonged exercise resulted in an increased T sk [17,[36][37][38][39][40][41][42][43][44][45][46]. In contrast, graded, intermittent or maximal exercises normally performed for brief period, resulted in decreased T sk [18,[47][48][49][50][51][52][53][54][55].…”

The invention of thermography, in the 1950s, posed a formidable problem to the research community: What is the relationship between disease and heat radiation captured with Infrared (IR) cameras? The research community responded with a continuous effort to find this crucial relationship. This effort was aided by advances in processing techniques, improved sensitivity and spatial resolution of thermal sensors. However, despite this progress fundamental issues with this imaging modality still remain. The main problem is that the link between disease and heat radiation is complex and in many cases even nonlinear. Furthermore, the change in heat radiation as well as the change in radiation pattern, which indicate disease, is minute. On a technical level, this poses high requirements on image capturing and processing. On a more abstract level, these problems lead to inter-observer variability and on an even more abstract level they lead to a lack of trust in this imaging modality. In this review, we adopt the position that these problems can only be solved through a strict application of scientific principles and objective performance assessment. Computing machinery is inherently objective; this helps us to apply scientific principles in a transparent way and to assess the performance results. As a consequence, we aim to promote thermography based ComputerAided Diagnosis (CAD) systems. Another benefit of CAD systems comes from the fact that the diagnostic accuracy is linked to the capability of the computing machinery and, in general, computers become ever more potent. We predict that a pervasive application of computers and networking technology in medicine will help us to overcome the shortcomings of any single imaging modality and this will pave the way for integrated health care systems which maximize the quality of patient care.

RESUMOA termografia médica infravermelha é um instrumento de análise não invasiva e não radioativa, capaz de analisar funções fisiológicas relacionadas com o controle da temperatura da pele. A termografia detecta a luz infravermelha emitida pelo corpo e visualiza mudanças de temperatura corporal relacionadas à alteração no fluxo sanguíneo. Não é um método que mostra anormalidades anatômicas, porém é capaz de mostrar mudanças fisiológicas. Existem várias aplicações da termografia no campo da medicina: desordens neurológicas, reumatológicas, musculares, doenças vasculares, patologias urológicas, ginecológicas, ortopédicas e na medicina esportiva. Para todas as áreas médicas, a termografia está estabelecida como uma medida que proporciona um mapeamento visual da distribuição da temperatura da pele. A termografia não deve ser usada como ferramenta diagnóstica única. Exames clínicos devem ser realizados para interpretação dos termogramas. Nas aplicações médicas, esta técnica proporciona, somente, uma imagem da distribuição da temperatura da pele; não é capaz de mostrar dados de uma superfície profunda do corpo, como é possível por outros exames de imagem. Entretanto, é um método não-invasivo e objetivo, além de seguro e inofensivo. Na medicina do esporte, o uso da termografia pode proporcionar melhores resultados aos atletas por ser um instrumento na identificação de riscos e na prevenção de lesões, além de ser uma importante ferramenta no acompanhamento do treinamento esportivo, a partir da avaliação da quantificação da carga de trabalho.Descritores: raios infravermelhos; reprodutibilidade dos testes; medicina esportiva/métodos; termografia/métodos. ABSTRACT Medical infrared thermography is a non-invasive, non-radioactive detection tool that is capable of analyzing physiological functions related to skin temperature control. Thermography detects infrared light emitted by the body and visualizes changes in body temperature related to changes in blood flow. It is not a method that shows anatomical abnormalities, but it is In medical applications, this technique only provides an image of the distribution of skin temperature; it is not capable of showing data for a deep surface layers of the body, as is possible with other imaging exams. However it is a non-invasive, objective method, as well as being safe and harmless. In sports medicine, the use of thermography can provide better results for athletes, as it is an instrument for identifying risks and preventing injuries, as well as an important tool for monitoring sports training, based on the evaluation of training load.
