Researchers using CT scans and 3-D printing have created accurate, custom-designed prosthetic replacements for damaged parts of the middle ear, according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA). The technique has the potential to improve a surgical procedure that often fails because of incorrectly sized prosthetic implants, researchers said.
High-tech prosthetics allow amputees to engage more fully in everyday life, even to compete in sporting events. Researchers from the University of Houston have demonstrated how brain activity is used to identify different terrains -- level ground and stairs, for example -- a key step in developing prosthetics that allow the user's prosthesis to automatically adjust to changing ground conditions in real time.
A new Tel Aviv University study suggests that a therapy that combines Virtual Reality and treadmill exercise dramatically lowers the incidence of falling among Parkinson's patients by changing the brain's behavior and promoting beneficial brain plasticity, even in patients with neurodegenerative disease.
Buttock augmentation is one of the fastest growing aesthetic procedures in the United States. According to the American Society for Aesthetic Plastic Surgery (ASAPS), more than 20,000 procedures were performed in 2016 alone, (a 3,267% increase compared to 2002, when ASAPS first began tracking statistics for buttock augmentation). ASAPS began tracking fat grafting to the buttocks in 2015, and for the two years it has collected that data, an average of 91% of all buttock augmentation procedures have consisted of fat grafting. Recently, The Aesthetic Surgery Education and Research Foundation (ASERF) formed the Gluteal Fat Grafting Task Force to investigate the risks associated with this increasingly popular procedure.
A new study by neuroscientists at the University of Chicago shows how amputees can learn to control a robotic arm through electrodes implanted in the brain.
Playing a video game that rewards participants for holding various "ninja" poses could help children and youth with autism spectrum disorder (ASD) improve their balance, according to a recent study in the Journal of Autism and Developmental Disorders led by researchers at the University of Wisconsin-Madison.
Stroke researchers at Kessler Foundation have proposed a theory for the high incidence of delirium and spatial neglect after right-brain stroke. Their findings are detailed in "Disruption of the ascending arousal system and cortical attention network in post-stroke delirium and spatial neglect", published Sept. 27, 2017 by Neuroscience & Biobehavioral Reviews. Authors are Olga Boukrina, PhD, research scientist, & A.M. Barrett, MD, director of Stroke Rehabilitation Research at Kessler Foundation.
Patients and family members are either neutral or uncomfortable with the idea of 'overlapping' or 'concurrent' surgery, where the attending surgeon isn't present in the operating room for part of the procedure, according to survey results published in the November 15, 2017 issue of The Journal of Bone & Joint Surgery. The journal is published in partnership with Wolters Kluwer.
Paralyzed rats implanted with engineered tissue containing human stem cells were able to walk independently and regained sensory perception in their hind legs and tail. The implanted rats also show some degree of healing in their spinal cords. The research demonstrates the great potential of stem cells to treat spinal cord injury.
If you visit your family doctor with low back pain (LBP), you may be surprised at the treatment options they suggest now. Recent changes to major international guidelines for the management of LBP mean that general practitioners (GP) are now unlikely to recommend pain medicines which were previously the go-to treatment. Instead of pain medicines, GPs might suggest non-medicinal approaches including yoga, mindfulness and various types of physiotherapy and psychological therapies.
