Abstract
Evaluation of sensibility in diabetic patients is a crucial factor to spot the group with different neuropathies, which play a crucial role within the development of foot ulcers. Various modalities of touch like pressure, vibration perception threshold (VPT) and two-point discrimination (TPD) are routinely wont to evaluate nerve injuries within the hand and, more recently; it is developed to check sensory loss or sensibility within the lower extremity. The two-point discrimination (TPD) test is one of the common tests for neurosensory tests to enact mechanoperception in clinical settings. Despite numerous studies within the functional sensibility of the upper extremity using the TPD test, there are relatively only a couple of reports on TPD within the lower extremity region. The aim of the proposed design may be a digitized handheld isobaric aesthesiometer to supply an equal force on the two prongs and to live TPD within the foot sole, which determines the degree of sensational loss and help the clinicians to understand the severity of peripheral nerve damage in diabetes.
