“…The temperature difference between the right and left limbs can be caused by relatively warming or cooling of either limb. 12 When the examinee has no overt foot symptoms, it is hard to tell which limb is responsible for the difference in temperature. In addition, the baseline body temperature varies greatly from one person to another, 6,24 and the peripheral temperature value also may change with core temperature from individuals.…”

The mean temperature of the entire plantar area was found to be more stable than the individual subregions, serving as a more practical indicator for thermoregulatory functions. The study also found that the overall mean plantar temperature stabilized after 15 minutes, and, thus, this time was recommended for clinical thermographic measurements. The normalized temperature may have more useful application than the plantar absolute temperature, as exemplified by the better correlation in diabetic feet. The mean plantar temperature, the wait time to start measurement, and the proposed normalization are believed to play important roles in neuropathic foot disorders.

“…The major argument is whether MIT can accurately determine thermal variations to enable sufficient quantitative analyses [ 20 ]. Proponents of MIT state that “state-of-the-art” computerized systems using complex statistical data analysis ensure high quality results [ 21 ] and that thermal sensitivity has increased, creating a new dimension that should be exploited and applied [ 22 ].…”

Medical infrared thermography (MIT) is used for analyzing physiological functions related to skin temperature. Technological advances have made MIT a reliable medical measurement tool. This paper provides an overview of MIT’s technical requirements and usefulness in sports medicine, with a special focus on overuse and traumatic knee injuries. Case studies are used to illustrate the clinical applicability and limitations of MIT. It is concluded that MIT is a non-invasive, non-radiating, low cost detection tool which should be applied for pre-scanning athletes in sports medicine.

“…These methods are not suitable for application to infrared image normalization, because these methods change the distribution of facial temperatures. Kakuta et al (2002) have proposed a method for infrared image normalization which utilizes the skin temperature subtraction to convert infrared images, as shown in Figure 4. This method can convert IR images obtained under various thermal environments into those under reference environments, in which the IR images contain foot, chest, hand and forearm.…”
