Article Synopsis
  • * Twenty-six participants, including 13 with diabetes and 13 healthy individuals, had their skin temperature monitored using a thermal camera to compare the temperature on insole use to baseline measurements.
  • * Results showed that a specific 2.5 mm-tall dimple insole effectively reduced temperature in certain foot areas better than a 4 mm-tall version, and it worked significantly better for the diabetic group, highlighting the potential for tailored insoles to help reduce foot complications in diabetes patients.

In Colombia, just the same as in the whole World, globalization of the market led to a large increase in importating of diverse devices. In case of devices for aesthetic use, importing a large number of different device types without adequate control of products, increases the risk of appearance of adverse events for their users. On the other hand, there are very few studies of adverse events caused by their use, or risk assessment studies.

This study was designed to assess the effect of time on the repeatability of the LorAn pressure distribution measurement system, and evaluate the variability of plantar pressure and postural balance, during barefoot standing in diabetic and non-diabetic subjects, for future diabetic foot clinical evaluation. Fourteen subjects were evaluated (8 females, 6 males, 8 non-diabetics and 6 diabetics, age range 30-70 years) and had no musculoskeletal symptoms. Four variables were measured with the platform in the barefoot standing position.

The changes in diameter of retinal vessels are an important sign of diseases such as hypertension, arteriosclerosis and diabetes. Obtaining precise measurements of vascular widths is a critical and demanding process in automated retinal image analysis. This paper presents the development of a prototype for measuring the vessel diameters to calculate the arteriovenous ratio (AVR) by using different techniques including Gabor wavelet, gradients, morphological operations and Niblack.

It has been well documented that subjects with peripheral neuropathy resulting from diabetes mellitus are at high risk of developing foot ulceration. Decreased sensation, in combination with high underfoot pressures, have been identified as prime etiology factors in the cause of plantar naturopathic ulceration [1]. This study presents the effect of four orthotic treatment techniques in reducing metatarsal head, heel and toes pressure during walking.
