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.
People with prosthetic arms or hands do not experience the "size-weight illusion" as strongly as other people, new research shows.
Our tactile senses keep us aware of our environment and are essential for the execution of natural movement. Though there have been many advances in modern prosthetic devices, the loss of sensory feedback remains an issue, and many amputees struggle with everyday movement.
Cracking the German Enigma code is considered to be one of the decisive factors that hastened Allied victory in World War II. Starting with clues derived from espionage, computer scientists were able to work out the rules that turned a string of gibberish characters into plain German, providing life-saving and war-shortening intelligence.
The brain's complex network of neurons enables us to interpret and effortlessly navigate and interact with the world around us.
High-tech prosthetics allow amputees to engage more fully in everyday life, even to compete in sporting events.
Researchers at Umeå University in Sweden have made a novel discovery connecting genetic innate immunity deficiencies to rampant caries and increased risk of dental caries affecting about one in five children.
A research team from National University of Singapore has developed a soft, flexible and stretchable microfibre sensor for real-time healthcare monitoring and diagnosis.
There's hope for a better life for people who've lost an arm or leg, thanks to new research funded by the National Science Foundation and the Department of Defense.
Glaucoma is a serious disease associated with increased intraocular pressure which often leads to blindness. One of the ways to treat glaucoma is to reduce aqueous humour secretion in the ciliary body of the eye by suppressing (inhibiting) activity of special enzymes - carbonic anhydrases.
Targeted motor and sensory reinnervation (TMSR) is a surgical procedure on patients with amputations that reroutes residual limb nerves towards intact muscles and skin in order to fit them with a limb prosthesis allowing unprecedented control.
Patients with a rare bone cancer of the skull and spine - chordoma - could be helped by existing drugs, suggest scientists from the Wellcome Trust Sanger Institute, University College London Cancer Institute and the Royal National Orthopaedic Hospital NHS Trust.
Traditional leg prosthetics enable amputees to maintain mobility and lead more active lives. But these prosthetics depend on soft limb tissue to function and can be painful to wear, resulting in awkward walking motion and possible skin infection.
A new method allows surgeons to reconstruct entire heart valves from the patient’s own tissue. This surgical procedure is currently only used at a handful of centers in the world.
The National Science Foundation has awarded $8 million to a consortium led by the University of California, Irvine to develop a brain-computer interface that can restore walking ability and sensation in individuals with spinal cord injury.
As humans walk and talk, we sense our own movements or sounds. Yet, we can distinguish our actions from everything else in our environment that affects our senses.
Freedom Innovations, a leading global designer and manufacturer of advanced technology lower limb prosthetics, today launched the Maverick™ Comfort AT, an all-terrain, fiberglass foot with a low profile designed to accommodate those with clearance challenges while providing comfort and ease of mobility with unsurpassed ground compliance.
The brain is very plastic, which means that the brain is able to adapt to new signals. In the case of bionic vision restoration, the photoreceptors have died, the brain is not receiving anything biologically, and you are going to then send something which is artificial, prosthetic, and has been created outside the body.
A short exposure to an alternating magnetic field might someday replace multiple surgeries and weeks of IV antibiotics as treatment for stubborn infections on artificial joints, new research suggests.
A team of Massachusetts General Hospital investigators has developed an antibiotic-releasing polymer that may greatly simplify the treatment of prosthetic joint infection.
Infections in surgically implanted heart valves are more common in patients who have been given a biological prosthetic valve than in those with a mechanical one, a study from Karolinska Institutet published today in the journal Circulation shows.
