Pressure-controlled insoles will help in the prevention of diabetic foot
Over time, diabetic patients have impaired sensitivity of the feet when they are no longer able to regulate the pressure on the shoes, which in the future can lead to stagnation, and, as a consequence, to ulcers and even amputation of the leg. A team of researchers at the University of Texas (Arlington), led by Mutu Wijesundara, is developing innovative insoles that automatically change the pressure on the foot in the interests of the patient.
The insoles are two-layer removable devices with built-in sensors that continuously monitor the load on the feet. In order to avoid prolonged pressure of the foot in one place, insoles having a cellular structure pump the fluid inside to different places, thereby ensuring normal blood circulation in the lower part of the foot.
The technology is adapted for people with a wide variety of weights. Innovative insoles can completely replace the plaster used to distribute weight over the foot during wound healing, as well as when monitoring the patient’s gait.
Currently, scientists are planning a practical study, which will be held in partnership with the University of Texas Southwestern Medical Center.
