Use an 8-10 MHz Doppler probe with a gel smeared over the sensor. Place the Doppler probe on the pulse area at a 45-60° angle to the skin surface.~Move the probe to find the most precise and robust arterial pulse before inflating the cuff.~The cuff is inflated about 20 mm Hg above the point where the arterial Doppler sound disappears.~Then slowly deflate until the Doppler sound reappears and records this value. The blood pressure at which the arterial pulse reappears is the systolic pressure for that blood vessel.~If the flow is still detected at the maximum inflation rate (300 mmHg), the cuff should be deflated immediately to avoid pain.
Subject will be trained to do regular foot exercise during their visit to the clinic. We will evaluate foot sensitivity and peripheral perfussion after
