Abstract
Diabetic peripheral neuropathy (DPN) has been identified as a key element in the causal pathway to foot ulceration and other lower‐extremity complications, impaired quality of life and increased mortality. Early detection is essential to optimise effective risk management, including adequate foot care, patient education, and future pharmacological therapy. However, data suggest that screening has been mostly sub‐optimal, and many physicians remain unfamiliar with non‐invasive screening tests. There is evidence in the literature to suggest that vibration perception threshold (VPT) measures can be used to easily and accurately identify at‐risk diabetic patients, including those with early neuropathic deficits. These measures have been used in population‐based studies and are associated with an increased risk of severe and expensive outcomes, such as ulcers and amputations. Incorporating VPT testing into clinical practice has the potential to significantly improve the outcomes in patients with DPN, thereby substantially reducing the socio‐economic burden of this common and challenging disease.
