emed diabetes novel

In the United States, every year, 8 out of every 1,000 Americans who have diabetes undergo amputation of a foot. One of the primary causes for this high number of amputations is the development of ulcers which develop as a result of high pressure on the foot. Nearly 85% of all non-traumatic foot amputations are preceded by foot ulcers. The emed® pedography platform is a device that can help in the fight to save the diabetic foot.

It is well known that the diabetic foot presents areas of high pressure which have a greater risk of developing pressure ulcers. The latest research suggests that the pressure risk threshold for ulceration in the diabetic foot is about 50-60 Newton per square centimetre. In most cases of diabetic neuropathic feet, the local pressures, especially under the forefoot, exceed this risk threshold. Detecting areas of high risk pressure can aid in the prevention of diabetic foot amputations.

The emed® platform is a device for recognition of elevated pressure patterns of the diabetic foot which may lead to ulcers and eventually amputation. By measuring plantar pressure of a person with diabetic neuropathy while walking, unsafe pressures under the foot can be detected. During the complete rollover process (foot strike to lift off), the typical neuropathic diabetic is said to have a "slapping" footfall. This type of step results in a higher and longer duration of pressure on the forefoot and lower pressure on the heels and toes than with a healthy person.

In addition to the standard therapy, it is recommended that the diabetic with local areas of high pressure immediately obtain adequate shoes and inserts. These assistive devices, provided by trained professionals, provide the ability to distribute the pressure evenly so the local pressure peaks can be reduced to safe levels. Clearly, patients must learn to care for their feet. With the information provided by the emed® pedography system, the health professional can explain, by using the colour-coded pressure footprints, which areas are specifically at risk.

The emed® pedography system is easy to use and does not create any additional work for the patient. emed® pedography is a valuable tool for achieving this goal of reducing the high number of amputations caused by pressure ulcers.
