11/09/2018Researchers from the Moscow Institute of Physics and Technology have developed a model for predicting hand movement trajectories based on cortical activity: Signals are measured directly from a human brain. The predictions rely on linear models. This offloads the processor, since it requires less memory and fewer computations in comparison with neural networks.
10/09/2018About eight in ten Germans suffer from back pain during their lifetime. Too much or the wrong movements can also cause problems. "Ran Rücken", the interdisciplinary research project aims to determine the right minimum dose of exercise that proves effective. (Explanatory note: "Ran Rücken" can be loosely translated as "Target the Back")
28/08/2018Researchers at EPFL's Biorobotics Laboratory studied eight gait parameters in order to come up with a very sophisticated software program that uses an avatar to predict how much energy people use when they walk depending on their walking style. This research has been published in Scientific Reports.
31/07/2018Patients with spinal fractures caused by tumors or osteoporosis usually undergo a procedure called kyphoplasty, where the fracture is filled with surgical cement. While kyphoplasty can stabilize the bone, cancer patients are still often left with spinal column tumors that are very hard to reach with conventional chemotherapy, which has to cross the blood-brain barrier when delivered intravenously.
10/07/2018A new positron emission tomography (PET) imaging method more fully evaluates the extent of rheumatoid arthritis by targeting translocator protein (TSPO) expression in the synovium (joint lining tissue). The study is featured in the July issue of The Journal of Nuclear Medicine.
02/05/2018X-rays for diagnostic imaging and therapy evaluation are still the norm in orthopedics. Meanwhile, patients who frequently need X-rays are repeatedly exposed to radiation. That's why the University Hospital RWTH Aachen uses and develops methods that are not just radiation-free but can also capture motions.
02/05/2018When human movements are no longer as smooth as they should be – due to misalignments or as the result of an injury for example – biomechanical measuring systems spring into action. Thanks to different types of sensors and optical technologies, physicians, therapists, and sports scientists embark on a search for possible causes and corrective options.
04/01/2018The position and alignment of surgical tools in the patient’s body must always be kept in view during the operation process to guarantee success and safety. With fine sensors at the tip of the instruments and an electromagnetic signal, Fiagon's electromagnetic navigation systems accurately reproduce their position in the body.
10/04/2017People with hip osteoarthritis often suffer from severe pain and only an endoprosthesis implantation can provide relief. This involves a major intervention and long-term rehabilitation because the implant requires the removal of a section of the thigh bone. The "MioHIP" research project looks for an elastic alternative.
24/10/2016Preoperative rehabilitation is gaining importance in medicine. It helps to prepare patients for upcoming treatments and surgeries, thereby reducing risks and complications during surgery and making faster rehabilitation possible.
22/01/2016It may fits, but somewhere it still tweaks. Although a suit off the rack serves its purpose, it is still far from being an ideal solution. With a custom made heart it is different. It is similar with implants. Often patients complain about the fact that those implants feel strange. 3D printing is on the best way to change this. Here, the implants are adapted to the carrier.
01/10/2014Even though exoskeletons for people requiring a wheelchair are nothing new, they are still controversial. After all, at first glance they suggest a miracle recovery. But this is not the actual intention. In fact, exoskeletons facilitate a special form of therapy that returns at least a small portion of independence to the respective person.
01/10/2014Herniated discs can have very different effects: some cause no discomfort and are only discovered by accident; others can cause paralysis or cause patients to be in great pain. For the most part, these problems develop suddenly after an awkward movement – at least that is what patients report.
