Prosthetic (Prosthesis) devices, such as an artificial leg, that replace a part of the body. Prostheses are typically used to replace parts lost by injury (traumatic) or missing from birth (congenital) or to supplement defective body parts. Inside the body, artificial heart valves are in common use with artificial hearts and lungs seeing less common use but under active technology development. Other medical devices and aids that can be considered prosthetics include artificial eyes, palatal obturator, gastric bands, and dentures.
In a set of proof-of-concept experiments, Johns Hopkins researchers have implanted electrodes in both sides of the brain of a person who is mostly paralyzed — with minimal sensation in his hands — to enable him to have some “mind control” of motorized prosthetic arms.
People who have had limbs removed often use false arms and legs, known as prosthetics, to improve mobility and independence - but 75 per cent of prosthetic-wearing amputees encounter problems like skin tears, ulceration, and blisters.
As a physically active college student Trevor LeMaster is no stranger to bodily aches and pains. He is a runner and a former high school wrestler who experiences soreness and workout injuries. LeMaster is also a transfemoral amputee and has first-hand knowledge of the impacts the fit of his prosthetic device has on his residual limb.
A new prosthesis powered by microscopic electrodes implanted in the thigh muscles of the wearer transmits natural sensations when the limb is touched, as well as with the movement of the limb.
A study has revealed a simulation that incorporates the hand's skin, muscles, bones, tendons and joints, which will be valuable for the development of biologically-inspired robotic hands.
Oral health is a critical component to overall health for all ages, but according to dental and medical experts from UConn Health, vigilance is especially critical for the elderly.
Combining new classes of nanomembrane electrodes with flexible electronics and a deep learning algorithm could help disabled people wirelessly control an electric wheelchair, interact with a computer or operate a small robotic vehicle without donning a bulky hair-electrode cap or contending with wires.
EPFL scientists are developing new approaches for improved control of robotic hands - in particular for amputees - that combines individual finger control and automation for improved grasping and manipulation.
Implantable brain electrodes have been around for quite some time now, both for diagnosing and treating neuropsychiatric conditions like Parkinson’s disease. However, one limitation of conventional probes is their size and rigidity, compared to the soft, gelatinous consistency of the brain.
People with hand amputations experience difficult daily life challenges, often leading to lifelong use of a prosthetic hands and services.
'Pilots' with physical impairments, who control computer avatars with their thoughts, will demonstrate how far brain-computer interface research has come as they compete in live events at CYBATHLON.
Patients fitted with an orthopedic prosthetic commonly experience a period of intense pain after surgery. In an effort to control the pain, surgeons inject painkillers into the tissue during the operation.
In a study recently published in Advanced Biomedical Engineering, researchers at Okayama University report a thin photoelectric film which can stimulate degenerated retinal tissues of the eye.
Keven Walgamott had a good "feeling" about picking up the egg without crushing it.
Robots and prosthetic devices may soon have a sense of touch equivalent to, or better than, the human skin with the Asynchronous Coded Electronic Skin, an artificial nervous system developed by a team of researchers at the National University of Singapore.
Opioids work against severe pain but the risks of side effects and addiction are high. In the USA alone, 26 people die every day from overdoses.
A new 3D-printed prosthetic hand can learn the wearers’ movement patterns to help amputee patients perform daily tasks, reports a study published this week in Science Robotics.
Researchers at the University of Bath have developed a new way of designing and manufacturing bespoke prosthetic liners, in less than a day.
Long-term hemodialysis is a lifesaver for approximately half a million patients in the United States with kidney failure (also known as end-stage renal disease, or ESRD) who are either waiting on or unsuitable for a kidney transplant.
EU-funded researchers and industrial partners are developing a system that allows a person to control the movement of a prosthetic hand simply by thinking of commands. A patient recently underwent surgery to implant some of the project's ground-breaking technologies.
