Lightly touching a stable, external supportive device with forces that provide only somatosensory cues, significantly attenuates postural sway of healthy individuals, which can be quantified by posturographic measurements. Higher forces would provide an inappropriate mechanical supporting effect that corrupts the analysis. The reduction in sway due to light touch (LT) of the fingertip on a stable surface in some cases can exceed the sway reduction provided by the visual reference, in both healthy subjects and in subjects with bilateral loss of vestibular function.

Diabetic neuropathy develops in 50\% of the patients with diabetes mellitus. The neurodegeneration increases the postural sway and decreases the stabilisation effect of fingertip touch reference.

This Thesis describes the development of a clinical software aiding the diagnostics of patients with diabetic neuropathy according to the fingertip touch reference (FTR) measurements. It contains a brief description of the posturographic control mechanisms and devices used to measure posturographic sway. Defines the parameters that are calculated during the posturographic meausurement of neuropathic patients. This document focuses on the software modules that analyze and visualize FTR information and evaluate these results to show the clinical significance of the measurements.
