Prosthetic News and Research

RSS

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.

Study reports greater psychosocial well-being in amputees using sensory-enabled prostheses

In the first known study of how amputees use advanced sensory-enabled prostheses outside the lab, subjects used a mechanical hand more regularly and for longer periods of time compared to traditional prostheses--and also reported a greater sense of psychosocial well-being.

MIT engineers develop simple, passive prosthetic foot that mimics natural walking

Prosthetic limb technology has advanced by leaps and bounds, giving amputees a range of bionic options, including artificial knees controlled by microchips, sensor-laden feet driven by artificial intelligence, and robotic hands that a user can manipulate with her mind.

Researchers create electronic skin that brings back real sense of touch to prosthetic limbs

Amputees often experience the sensation of a "phantom limb"--a feeling that a missing body part is still there.

Medicare takes aim at boomerang hospitalizations of nursing home patients

"Oh my God, we dropped her!" Sandra Snipes said she heard the nursing home aides yell as she fell to the floor. She landed on her right side where her hip had recently been replaced.

Study reveals how the brain coordinates complex articulatory movements during natural speech

When we speak, we engage nearly 100 muscles, continuously moving our lips, jaw, tongue, and throat to shape our breath into the fluent sequences of sounds that form our words and sentences. A new study by UC San Francisco scientists reveals how these complex articulatory movements are coordinated in the brain.

FDA approves first stand-alone prosthetic iris in the U.S.

The U.S. Food and Drug Administration today approved the first stand-alone prosthetic iris in the United States, a surgically implanted device to treat adults and children whose iris (the colored part of the eye around the pupil) is completely missing or damaged due to a congenital condition called aniridia or other damage to the eye.

Novel surgical approach to limb amputation improves sensation, control of prosthesis

Humans can accurately sense the position, speed and torque of their limbs, even with their eyes shut. This sense, known as proprioception, allows humans to precisely control their body movements.

New technology could make prosthetic use more intuitive and reliable

Researchers have developed new technology for decoding neuromuscular signals to control powered, prosthetic wrists and hands. The work relies on computer models that closely mimic the behavior of the natural structures in the forearm, wrist and hand.

Researchers develop new method that could increase longevity of artificial hips

Mechanical engineering researchers have developed a method that could extend the life of an artificial hip by adding an array of microscopic indentations that increase the thickness of a lubricating film on its surface.

Study shows effectiveness of novel risk tool to predict readmission rates after TAVR

A new study looked at the effectiveness of novel risk tool to predict 30-day readmission rates in patients undergoing transcatheter aortic valve replacement.

Study examines efficacy of 3D printing, computer modeling to predict paravalvular leak in TAVR

A new study examines the effectiveness of 3D printing technology and computer modeling to predict paravalvular leak in patients undergoing transcatheter aortic valve replacement (TAVR). A common risk of TAVR is an ill-fitting valve which can lead to PVL.

Researchers identify independent predictors of both delayed and early discharge post TAVR

A new study finds patients who stay in the hospital for more than 72 hours when undergoing trans-femoral transcatheter aortic valve replacement (TF-TAVR) procedure may be associated with negative short and long-term outcomes.

New prosthetic arms stimulate nerves with mild electrical feedback

Losing an arm doesn't have to mean losing all sense of touch, thanks to prosthetic arms that stimulate nerves with mild electrical feedback.

Researcher presents case study of asymptomatic patient with severe mitral regurgitation

In primary mitral regurgitation there are anatomic abnormalities of the mitral valve causing backward flow, placing a hemodynamic burden on the left ventricle.

Medical device coated with new bacteria resistant materials approved for use by hospitals

A medical device coated with new bacteria resistant materials, discovered by a team at the University of Nottingham, has been approved for use by hospitals in the UK and Europe.

Researchers develop thin, flexible polymers to record activity more deeply in the brain

Science has yet to unravel a complete understanding of the brain and all its intricate workings. It's not for lack of effort.

Scientists demonstrate successful implementation of prosthetic memory system

Scientists at Wake Forest Baptist Medical Center and the University of Southern California (USC) have demonstrated the successful implementation of a prosthetic system that uses a person's own memory patterns to facilitate the brain's ability to encode and recall memory.

New study reveals why some visual cues remain subliminal

Understanding conscious perception is a major challenge for neuroscience. A new study published on March 22nd in Science now shows why weak visual stimuli of the same strength are sometimes detected and other times remain subliminal: As the signals travel from visual areas to the prefrontal cortex, fluctuating brain dynamics can make the difference, elevating some signals above the threshold of conscious experience and stopping others in their tracks.

Students build 3D-printed, low-cost robotic prosthetic hand for amputees

Students at The University of Manchester have designed and built a 3D printed, low-cost robotic prosthetic hand that could provide a much cheaper alternative for amputees.

Researchers find new method to restore movement sensation in patients with prosthetic arms

A team of researchers led by Cleveland Clinic has published first-of-its-kind findings in Science Translational Medicine on a new method of restoring natural movement sensation in patients with prosthetic arms.
