To reduce the likelihood of consequences caused by impaired blood flow, scientists from Lithuania have developed an ultrasonic foot stimulation device that can non-invasively improve blood circulation in the lower limbs, with the aim of preventing diabetic foot. This innovative device was created through a collaborative effort of scientists from the Kaunas University of Technology (KTU) and the Lithuanian University of Health Sciences (LSMU).
The device uses particular piezoelectric elements to generate a broad spectrum of acoustic ultrasound waves in response to an electrical signal. Then, after selecting the appropriate parameters, the ultrasound is transmitted to the foot tissues and can stimulate blood flow in practically the entire leg. In this way, it is possible to regulate thrombogenesis, immune response, and inflammatory processes, which are essential for normal vascular and general tissue function. In addition, ultrasound waves can act on nerve structures, considering that all blood vessels have innervation and thus activate vascular tone in a vast tissue area.
The device’s operation is non-contact and non-thermal, which minimizes possible adverse events. It can be tailored for individual use with appropriate software modifications, making it a valuable tool for patients with diabetes and other peripheral circulatory disorders. It also holds promise for older individuals with chronic vascular dysfunction.
