Researchers at Hebrew University have developed a new sock that will alert Diabetic patients with neuropathy (numbness in the feet) when they may develop pressure ulcers. When the feet are numb, the patient may not feel if they are putting too much pressure on a particular part of the foot. A person without neuropathy would just switch the pressure point by shifting weight to a different part of the foot, or to the other foot, or by loosening a lace, etc. But if you can’t feel, you wouldn’t know that one part of the foot is bearing too much prolonged weight and pressure. This prolonged pressure could cause the skin to break open and a wound, or diabetic ulcer, to form. An infected wound could be the incident that starts the progression toward an amputation of a toe, foot or leg. See the article here.
