Osgood-schlatter Disease Diagnosis by Algometry and Infrared Thermography

Abstract

Background: The diagnosis of Osgood-Schlatter Disease (OSD) is based on clinical signs and symptoms. However, more objective parameters, like thermal images, have been researched to determine, along algometry, valid parameters. Objective: The aim of this study was to analyze the thermal differences and the painful sensibility between the knees (with SOS and contralateral) of young soccer players. Methods: 6 young men, aged between 12 and 15, members of football schools, composed the sample. Images were taken from an anterior view of both knees, with the volunteer in a seated position, the knees flexed at 90º degrees and both feet flat on the floor. After the thermal image capture, the patients were submitted to an evaluation with the pressure algometer. Results: According to the results, it was found that the knee affected by the OSD showed temperatures significantly higher than the contralateral (p = 0.027) and also greater sensitivity to the pressure algometry (p = 0.027). Conclusion: it can be concluded that the inflammatory process, during OS Syndrome, promotes a local thermal hyper-radiation, identified with the high sensitive thermographic infrared image, producing a significant difference in local temperature between the knees of a single individual. Moreover, this process also increases the pain sensibility, accessed by pressure algometry.

“…Recently, other objective methodologies, such as algometry or thermography, have been used as diagnostic tools, with promising results [ 75 ].…”

Superficial thermal response to CrossFit® workout

“…The interest in research with athletes and others engaged in physical activity is not new, however, the study of the superficial thermal response (skin temperature) started a few decades ago 1 . Studies with thermal images with team sports such as football 2 and rugby 3 have been developed in order to assess the recovery of athletes and the incidence of muscle overuse resulting from training.…”

Thermal Images in the Assessment of Post-Herpetic Neuralgia: A Case Study

“…Using thermographic images, it is possible to detect and delimit areas of thermal asymmetry and compare them with regions of thermal or tactile hyperalgesia, which do not result in mapping where the problem occurs [5]. Its use as a diagnostic method is based on the fact that different types of processes are manifested by changes in heat production and changes in blood flow patterns in organs and tissues [6][7][8]. In this sense, the aim of this study was to present a case of post-herpetic neuralgia (PHN) assessed and with its therapeutic approach monitored by thermal images.…”
