Freezing Technique May Ease 'Phantom Limb' Pain for Amputees

Posted 8 Apr 2016 by

FRIDAY, April 8, 2016 – A freezing technique may reduce the debilitating phantom limb pain that many amputees experience, according to a new, small study. Chronic pain that emanates from the site of a severed limb can be reduced in some cases when the remaining nerve and scar tissue is frozen in place, researchers said. The minimally invasive technique, known as cryoablation therapy, may offer hope to the roughly 200,000 Americans who undergo an amputation every year, according to U.S. Centers for Disease Control and Prevention statistics. Many such patients, including military veterans and people with diabetes, experience a crippling form of nervous system disorientation after losing a limb. The study authors said the problem stems from inaccurate signaling among the remaining limb nerve endings and/or overactivity among neighboring nerves. The result is a distinct feeling of limb ...

Amputee 'Feels' With Bionic Fingertip

Posted 9 Mar 2016 by

TUESDAY, March 8, 2016 – A bionic fingertip enabled an amputee to feel different textures, researchers report. The fingertip was linked to electrodes surgically implanted into nerves in Dennis Aabo Sorensen's upper arm. Sorenson was able to feel smoothness and roughness with the fingertip, the researchers said. A machine controlled the movement of the fingertip over pieces of plastic with different rough or smooth patterns. As the fingertip moved over the plastic surfaces, sensors generated electrical signals that were sent to the nerves in Sorensen's upper arm. He could tell the difference between smooth and rough textures 96 percent of the time, the researchers said. The successful test of the bionic fingertip could help speed efforts to develop artificial limbs that provide sensory feedback, according to Silvestro Micera, from Ecole Polytechnique Federale de Lausanne (EPFL) in ...
