App helps orthopedic surgeons plan procedures

Tel Aviv based Voyant Health‘s TraumaCad Mobile app helps orthopedic surgeons plan operations and create result simulations.  The system offers modules for  hip, knee, deformity, pediatric, upper limb, spine, foot and ankle, and trauma surgery.  The iPad app mobile version of this decade old system was recently approved by the FDA. Surgeons can securely import medical images from the […]

BCI enabled 10-D prosthetic arm control

Jennifer Collinger and University of Pittsburgh colleagues have enabled a prosthetic arm wearer to reach, grasp, and place a variety of objects with 10-D control for the first time. The trial participant had electrode grids with 96 contact points surgically implanted in her brain in 2012.  This allowed 3-D control of her arm. Each electrode point picked up signals […]

Applied robot control theory for more natural prosthetic leg movement

Prosthetics are lighter and more flexible than in the past, but fail to mimic human muscle power. Powered prosthesis motors generate force, but cannot respond with stability to disturbances or changing terrain. Robert Gregg and colleagues at the University of Texas have applied robot control theory to allow powered prosthetics to dynamically respond to a wearer’s environment. […]

NIH “Bionic Man” with 14 sensor and brain controlled functions

The National Institute of Biomedical Imaging and Bioengineering recently launched the “NIBIB Bionic Man,” an interactive Web tool detailing 14 sensor based technologies they are supporting.  They include: 1. A robotic leg prosthesis that senses a person’s next move and provides powered assistance to achieve a more natural gate. 2. A light sensitive biogel and […]

Virtual reality movement training for amputees

CAREN, developed at the University of South Florida, helps those with limb loss and prosthetics improve basic function, symmetry and walking efficiency.  It is also a tool for researchers to study ways to improve mobility and balance. Wearing a safety harness and walking on a  treadmill in the room-sized system, participants of a recent study engaged in audio-visual balance […]

“Brain modeled” chip with prosthetic potential

Neurogrid is a “human brain based” microchip that is 9,000 times faster than and requires 1/40,000 the power of a typical pc.  It is being developed by Professor Kwabena Boahen at Stanford University. The circuit board consists of 16 custom-designed “Neurocore” chips which can simulate 1 million neurons and billions of synaptic connections. Certain synapses were enabled […]

BCI and robotic prosthetic paralympic competition

Switzerland will host the world’s first Cybathlon, an Olympic-style competition for parathletes using robotic assistive devices and brain computer interfaces. It will include six events: a bike race, leg race, wheelchair race, exoskeleton race, arm prosthetic race (including electrical muscle stimulation), and a Brain Computer Interface race for competitors with full paralysis. Unlike the Olympics, where athletes […]
