Prosthetics: Cranking up the power

09/11/2018

Amputees who use powered prosthetic ankles may be able to avoid the energetic costs typically associated with prosthetics by cranking up the power provided by their devices.

How to predict life of implants without animal testing

24/09/2018

An international team of researchers consisting of scientists from NUST MISIS and TU Dortmund University has developed a technology to study the behavior of orthopedic implants in laboratory conditions as close as possible to the human body. The technology is notable for its ethics: the research can be carried out in vitro - that is, without involving lab animals.

Chip controlling exoskeleton keeps patients' brains cool

11/09/2018

Researchers 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.

Back pain: The research project Ran Rücken is intended to help

10/09/2018

About 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")

An avatar uses your gait

28/08/2018

Researchers 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.

Light and Bluetooth – dynamic measurement techniques for orthopedics

02/05/2018

X-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.

Biomechanical measuring systems: Versatile tools for many disciplines

02/05/2018

When 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.

The surgeon's co-pilot: pin-point accuracy through electromagnetic navigation systems

04/01/2018

The 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.

Hip joint: sleeve versus endoprosthesis

10/04/2017

People 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.

Preoperative rehabilitation: Fit for surgery

24/10/2016

Preoperative 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.

Customized Implants cover bones optimally

22/01/2016

It 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.

HAL Exoskeleton – A Step toward Independence?

01/10/2014

Even 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.

Spinal disc herniation: causal research with the simulator

01/10/2014

Herniated 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.
