 | A new lower-limb prosthetic uses the latest advances in computer, sensor, electric motor and battery technology to give it bionic capabilities. ...> Full Article |
 | "Brain cap" technology being developed at the University of Maryland allows users to turn their thoughts into motion. Associate Professor of Kinesiology Jose "Pepe" L. Contreras-Vidal and his team have created a noninvasive, sensor-lined cap with neural interface software that soon could be used to control computers, robotic prosthetic limbs, motorized wheelchairs and even digital avatars. ...> Full Article |
Engineering researchers at Rice University, the University of Michigan, Drexel University and the University of Maryland have begun designing a prosthetic arm that amputees can control directly with their brains and that will allow them to feel what they touch. While it may sound like science fiction, the researchers say much of the technology has already been proven in small-scale demonstrations.

A new test shows promise for detecting the early stages of a major cause of failure in joint replacement implants, so that patients can be treated and perhaps avoid additional surgery. More than 1.5 million total joint replacement operations are performed worldwide each year. While the success rate is 90 per cent, almost 10 per cent of implants fail and require additional surgery, report appears in the ACS journal Molecular Pharmaceutics.

 | University of Utah scientists used invisible infrared light to make rat heart cells contract and toadfish inner-ear cells send signals to the brain. The discovery someday might improve cochlear implants for deafness and lead to devices to restore vision, maintain balance and treat movement disorders like Parkinson's. ...> Full Article |
 | Researchers at Brown University have created nanoscale surfaces for implanted materials that mimic the contours of natural skin. The surfaces attract skin cells that, over time, are shown to build a natural seal against bacterial invasion. The group also created a molecular chain that allows an implant surface to be covered with skin cell-growing proteins, further accelerating skin growth. Results are published in the Journal of Biomedical Materials Research A. ...> Full Article |
The National Eye Institute (NEI) and Food and Drug Administration (FDA) are sponsoring a conference to determine how functional vision-related endpoints for clinical trials of visual prostheses will be analyzed and correlated with objective measures of visual acuity, visual fields and contrast sensitivity. These assessments may provide valuable information that will corroborate standard clinical test outcomes.

Leave your body and shake hands with yourself, gain an extra limb or change into a robot for a while. Swedish neuroscientist Henrik Ehrsson has demonstrated that the brain's image of the body is negotiable. Applications stretch from touch-sensitive prostheses to robotics and virtual worlds.

Washington University in St. Louis biomedical engineer Daniel Moran is developing brain-computer interfaces based on grids of electrodes that lie beneath the skull but outside the dura mater, the protective membrane that covers the brain. His next project is to slip a thin 32-electrode grid he designed with a colleague under a macaque's skill and to train the monkey to control -- strictly by thinking about it -- a computational model of a macaque arm.

 | You may have heard of virtual keyboards controlled by thought, brain-powered wheelchairs, and neuro-prosthetic limbs. But powering these machines can be downright tiring, a fact that prevents the technology from being of much use to people with disabilities, among others. Professor José del R. Millán and his team at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have a solution: engineer the system so that it learns about its user, allows for periods of rest, and even multitasking. ...> Full Article |
A University of Houston professor is leading a multi-institution team that is helping DARPA build mind-controlled prosthetics that can last a lifetime.

Last year 12,700 knee replacement operations were carried out in Sweden. Most such operations go well, but some patients are affected by bacterial infection in the joint and have to be re-operated. This is a complicated procedure that does not always produce successful results, as shown in a thesis by Anna Stefánsdóttir from Lund University in Sweden.

 | Using beams of light to allow amputees not only to control but also to feel the movement of prosthetic limbs is the ambitious goal of a new $5.6 million Department of Defense initiative. ...> Full Article |
Two experimental brain-machine technologies -- deep brain stimulation coupled with physical therapy and a thought-controlled computer system -- may offer new therapies for people with stroke and brain injuries, new human research shows. In addition, an animal study shows a new artificial retina may restore vision better than existing prosthetics. The findings were announced today at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.

 | The Defense Advanced Research Projects Agency (DARPA) has awarded a contract for up to $34.5 million to The Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., to manage the development and testing of the Modular Prosthetic Limb (MPL) system on human subjects, using a brain-controlled interface. ...> Full Article |

 | An artificial foot that recycles energy otherwise wasted in between steps could make it easier for amputees to walk, its developers say. ...> Full Article |
More than 1,200 American soldiers have returned from Afghanistan and Iraq with missing limbs. To address this growing national need, researchers at Worcester Polytechnic Institute are laying the groundwork for a new generation of advanced prosthetic limbs that will be fully integrated with the body and nervous system. As part of the recently approved Department of Defense appropriations bill, WPI's Center for Neuroprosthetics and BioMEMS received a $1.6 million allocation to advance this groundbreaking work.

 | Arizona State University researchers have developed a prosthetic device that literally puts the spring back into an amputee's step. The ASU scientists have developed and refined SPARKy (for spring ankle with regenerative kinetics) into a smart, active and energy storing below-the-knee (transbitial) prosthesis. ...> Full Article |
 | The artificial lower limbs of double-amputee Olympic hopeful Oscar Pistorius give him a clear and major advantage over his competition, taking 10 seconds or more off what his 400-meter race time would be if his prosthesis behaved like intact limbs. That's the conclusion -- released to the public for the first time -- of human performance experts Peter Weyand of Southern Methodist University and Matthew Bundle of the University of Wyoming. ...> Full Article |
 | A URI engineer has been tripping amputees in a laboratory study that seeks to improve the safety of prosthetic legs by developing a reliable and responsive stumble detection system.
