Abstract

The population of diabetes is continuously increasing because of the economic development and the lifestyle modification. If diabetes become chronic condition, it can cause various complications. Among many other complications, diabetic foot is the most fatal issue since it may require amputation of the legs. Diabetic foot has three different types such as neuropathic, neuro-ischemic and ischemic. Among these types, patients of neuropathic foot experience sensory abnormality. Nerve conduction velocity (NCV) is used for diagnosing neuropathic foot but this method uses strong electric stimulus to cause severe pain to the patients In this study, two channel photo-plethysmography was used as noninvasive screening tool for distinguish neuropathic foot and normal group by observing blood flow of both finger and toe simultaneously.
