Currently, the population percentage of diabetics suffering Diabetic Peripheral Neuropathy (DPN) and foot-drop gait anomaly was estimates as 15% in the United States. The onset of foot-drop could not be detected until symptoms could be observed visually, patient falling or patient experiencing painful gait issues and expensive medical tests. This research showed that by utilizing the plantar-pressure characteristics of DPN drop-foot gait, a set of index could be developed for the severity of DPN.
