19/08/2021For people with amputation who have prosthetic limbs, one of the greatest challenges is controlling the prosthesis so that it moves the same way a natural limb would. Most prosthetic limbs are controlled using electromyography, a way of recording electrical activity from the muscles, but this approach provides only limited control of the prosthesis.
08/07/2021Researchers at the University of Freiburg and the University of Stuttgart have developed a new process for producing movable, self-adjusting materials systems with standard 3D-printers. These systems can undergo complex shape changes, contracting and expanding under the influence of moisture in a pre-programmed manner.
01/07/2021Orthopedic technology involves taking a measurement of a specific body part and then creating a medical device, be it prosthesis or orthosis, that fits. While optical scanners are already used for some of these measurements, others are still performed through manual labor and craft to create molds of the body. 3D scanners are changing this.
01/07/2021When auxiliary means like orthoses or prostheses do not come from the shelf, but are adapted to the wearer, this means true crafting: In the past, a plaster mold of a body part had to be made as a template to create an individual aid from it step by step. Fortunately, we have come a long way until today.
22/09/2020Patients who receive a prosthesis after the amputation of a limb often have to train for weeks or months until they can control the technology and use it in everyday life without problems. At the Medical University of Vienna, the world's first bionic prosthesis has now been developed that has a closed control loop and enables immediate, intuitive use.
22/11/2018Every year between 250.000 and 500.000 people suffer a spinal cord injury, MoreGrasp is intended to make their lives easier. The project aims to restore the lost gripping function in people with high paraplegia. Researchers at Graz University of Technology have developed a neuroprosthesis that is currently undergoing a feasibility study.
23/07/2018Every year, more than 250,000 patients worldwide receive heart valve implants. Children require repeated replacement surgery because their bodies are still growing, the prosthetic heart valves are not. Regenerative heart valves solve this problem. Until now, we have only been able to monitor how these living implants develop in the body after the fact. Computer models now make this predictable.
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.
06/03/2018With the help of surgical navigation systems, prostheses or implants can be better inserted. During the procedure, surgeons can see exactly where they need to operate on a screen. Just like a navigation system in the car, navigation in the OR guides you precisely to your destination. At the Uniklinik RWTH Aachen we can find out what advantages this has for physicians and patients.
