Diabetes mellitus is not only a clinical syndrome characterizing hyperglycemia, but is also a cause of debilitating problem known as peripheral neuropathy (PN). This review addresses the importance of diagnosing PN in a clinical setting as PN causes pain and discomfort in lower extremities, loss or absence of protective sensations in the lower extremities leading to balance problems, risk of foot ulcerations, and a reduced quality of life in adults with type 2 diabetes. A variety of modalities or methods are available to evaluate both subjective and objective measures of peripheral nerve functions, and have been discussed in detail in this review. It is of utmost importance to understand that evaluating PN as a routine practice in a simple way may also play a vitally important role in preventing foot ulcers or fall-related morbidity and mortality in adults with type 2 diabetes.
