A multivariate NIR study of skin alterations in diabetic patients as compared to control subjects

A group of 15 diabetic persons with different degrees of diabetes complicat ions, including skin changes, was studied by Fourier Transform Near Infrare d (FT-NIR) spectroscopy. Skin reflectance spectra were measured with a fibr e-optic probe in four locations (sites): hand, arm, leg and foot. For refer ence, a group of 28 healthy controls was also measured, Multivariate analys is of the NIR spectra obtained shows a high potential for classification an d discrimination of the skin conditions. Valuable indications for future ex periments can be observed.
