Exoskeleton: walk and run more easily

16.08.2019

Between walking at a leisurely pace and running for your life, human gaits can cover a wide range of speeds. Typically, we choose the gait that allows us to consume the least amount of energy at a given speed. For example, at low speeds, the metabolic rate of walking is lower than that of running in a slow jog; at high speeds, the metabolic rate of running is lower than that of speed walking.

Robotics: novel neck brace improves functions of ALS patients

13.08.2019

A novel neck brace, which supports the neck during its natural motion, was designed by Columbia engineers. This is the first device shown to dramatically assist patients suffering from Amyotrophic Lateral Sclerosis (ALS) in holding their heads and actively supporting them during range of motion.

Medical back supports: human torso simulator offers promise for back brace

02.08.2019

Engineers have for the first time created a simulator mimicking the mechanical behaviour of the human torso - which could lead to innovations in the design of medical back supports. It allows researchers to test different back brace designs and configurations without needing to test them on people - removing significant logistical and ethical issues.

Nanotechnology: an 'EpiPen' for spinal cord injuries

15.07.2019

An injection of nanoparticles can prevent the body's immune system from overreacting to trauma, potentially preventing some spinal cord injuries from resulting in paralysis. The approach was demonstrated in mice at the University of Michigan, with the nanoparticles enhancing healing by reprogramming the aggressive immune cells.

Prosthetic hand: 3D printed and combinable with a computer interface

08.07.2019

Losing a limb, either through illness or accident, can present emotional and physical challenges for an amputee, damaging their quality of life. Prosthetic limbs can be very useful but are often expensive and difficult to use.

Sports medicine - performance values in best health

01.07.2019

Those who integrate physical activities into their own lifestyle live healthier and more balanced. But where are the physical limits? Can health status measurements also be carried out on the road? Discover more about how sports medical examinations contribute to maintain performance and minimize health risks in our Topic of the Month.

Performance diagnostics: success in sports – testing the limits of performance

01.07.2019

Stationary or mobile - competitive athletes rely on regular health assessments. They must deliver peak performance and be physically fit during competitions. But when do they reach their physical limits? Are there any devices that provide information, no matter where the test subject is located?

AI: recognizing pathological movement patterns

28.06.2019

Reliably evaluating walking and gripping movements of patients is essential for the diagnosis and therapy of movement disorders, for example after a stroke or in Parkinson's syndromes. However, the success of this challenging diagnostic procedure depends to a large extent on the experience and skills of the attending physician.

Rehab with a robot – robot-assisted therapy in neurology

03.06.2019

It takes consistent repetitions if rehab patients want to relearn skills after surviving a stroke. This requires extreme effort. The industrial sector uses robots to perform repetitive tasks or handle jobs that require strength. What has been a fixture in factories for decades is now also making its way into rehabilitation facilities.

Orthopedic implant: More comfortable thanks to full weight-bearing capacity

08.03.2019

Orthopedic implants – they are a necessity when it comes to congenital or acquired limb length discrepancies. However, full weight-bearing during the limb lengthening process is not feasible with previous implant models. For the first time, the 3D Surgery division at the Medical Center of the University of Munich has succeeded in using an implant that facilitates immediate weight-bearing.

SoftHand: grasping intelligence for lower arm prostheses

10.12.2018

So far, lower arm prostheses often only functioned as a cosmetic disguise to conceal the missing body part. While newer models help the wearer with grip patterns, every hand grip has to be readjusted and newly activated. There is still no prosthetic device that is easy to control and allows a flexible response to objects the wearer is grasping.

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")

Biomechanical measuring systems – motion and posture analysis in orthopedics

21.06.2018

Biomechanical measuring systems are used in orthopedics to diagnose and treat misalignments and diseases. The Velamed Company uses its high-tech solutions to measure biomechanical parameters that enable a holistic analysis of human movement and posture. We took a closer look at how this works.

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.

Surgical navigation systems – with precision to the destination

06.03.2018

With 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.

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.
