New insoles to treat diabetic ulcers

A new show insole has been developed by Purdue University in order to help prevent amputation of toes, feet and legs of diabetics who are currently suffering from diabetic ulcers. The insoles have been designed to slowly release oxygen to the foot, which in turn heals the ulcers and allows the user to be able to regain more mobility.  Diabetic ulcers are caused by damaged nerves which causes skin tissue to disintegrate as well as the lack of feeling, meaning that damage to the foot can go unnoticed, and therefore doesn’t receive the appropriate treatment.  “We typically treat ulcers by removing devitalised tissue from the surface of the wound, and by helping the patient to find ways to take the weight off the affected foot,” said Desmond Bell, a podiatrist in wound ma

Paralysis in three patients treated with electrical simulation.

A medical breakthrough by GTX Medical, led by the Swiss professors Grégoire Courtine and Bloch, has enabled three patients, all suffering with chronic paraplegia, to walk again thanks to wireless electrical simulation.  The wireless implant is inserted onto the spinal cord where it contains a multitude of electrodes which can send specific messages to specific muscle groups, just as the brain would.  “Selected configurations of electrodes are activating specific regions of the spinal cord, mimicking the signals that the brain would deliver to produce walking,” said Prof Jocelyne Bloch, a neuroscientist at Lausanne University Hospital (CHUV/Unil). Each of the patients who undertook the electrical simulation found that not only could they move and control their paraly
