These factors associated with Limb ischemia increases the chances of foot ulceration leading to amputation.
So investigations like Biothesiometer, Semmes- Weinstein Monofilament Test for Neuropathy, AB Index by Dopplers for ischemia, Foot Scan for pressure assessment are basic investigations a patient of Diabetes should undergo in Diabetes foot clinic in helping the Doctor to prevent the Foot ulceration.
