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.
A new method to accurately record brain activity at scale has been developed by researchers at the Crick, Stanford University and UCL.
Walking and running subjects our feet to forces in excess of body weight. The longitudinal arch of the feet was thought to be the reason the feet do not deform under such load.
A breakthrough medical technology can save the lives of children with heart defects. Scientists have developed the first-ever heart valve that grows with the child, reducing the need for risky heart surgeries in the future.
Siddhartha Sikdar, Professor, Bioengineering, Volgenau School of Engineering, Parag Chitnis, Assistant Professor, Bioengineering, and Guoqing Diao, Associate Professor, Statistics, are working to develop and evaluate a prototype prosthetic control system that uses wearable ultrasound imaging sensors to sense residual muscle activity rather than electromyography.
Reaching for something on the top shelf in the grocery store or brushing one's teeth before bed are tasks many people can do without thinking. But doing these same tasks as an upper limb amputee, while using a prosthetic device, can require more mental effort.
The lightweight device with soft grip fingers uses an armband fitted with sensors to detect electrical signals naturally conducted by muscles. This enables the toddler to grip and pick up objects in much the same way as they would with a natural arm.
Neural stimulation is a pioneering technology that can be used to recover function and improve the quality of life for individuals who suffer from brain injury or disease.
For the first time, scientists identified and mapped the location of structural proteins in a pig ovary. Ongoing development of an "ink" with these proteins will be used for 3-D printing an artificial (or bio-prosthetic) ovary that could be implanted and allow a woman to have a child.
A recently published study indicates that oral infections seem to have no association with the risk of stem cell transplantation patients dying of or getting a serious infection within six months of the procedure.
Macular degeneration causes blindness in millions of people in the Western world. It is the most common cause of severe vision loss in the Western world among those aged 50 and over, and its prevalence increases with age.
Sensing a hug from your friend through a video call with him/her may become a reality soon. A joint-research team consisted of scientists and engineers from City University of Hong Kong and Northwestern University in the United States has developed a skin-integrated virtual reality system, which can be controlled and powered wirelessly.
Standard diagnostic methods are not adequate to identify prosthetic joint infections in patients with rheumatic diseases, according to findings from a new study by researchers from Hospital for Special Surgery in New York City.
Older adults are at an especially high risk for mouth and tooth infections and the complications that can come with these problems.
For a brief time, Kerry Finn felt like "The Terminator" or "The Six Million Dollar Man."
For a brief time, Kerry Finn felt like "The Terminator" or "The Six Million Dollar Man." The 60-year-old retired truck driver from Salt Lake County, Utah, lost his left leg to vascular disease from type 2 diabetes.
Mick Jagger owes some thanks for the fact he's alive and strutting to Ajit Yoganathan and his lab crew. In fact, millions of people do.
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.
