Aston University scientists have discovered a more accurate way of checking the blood flow in the feet of patients with Type 2 diabetes.
Using lasers, their findings have resulted in improved accuracy in detecting tiny changes in microcirculation – the smallest vessels within the circulatory system. Changes in flow at this level can affect whether tissue lives or dies. People with Type 2 diabetes can be at risk of foot amputations due to circulatory complications caused by their condition.
The new approach underwent tests on both healthy volunteers and pilot clinical trials on diabetes patients by applying a probe to their skin. The new method showed a significant improvement in the diagnostic accuracy of detection of microvascular changes in the skin of the feet in patients with Type 2 diabetes.
