Researchers from the University’s School of Health Professions & Rehabilitation Sciences and the School of Electronics & Computer Science (ECS). have developed a technology to help stroke patients to re-learn movement.
Dr Jane Burridge from the School of Health Professions & Rehabilitation Sciences who is leading the research commented: ‘As far as we know, nobody has tried using a technique called iterative learning control, to help people who have had a stroke to move again. It is a great example of how state of the art control theory, normally used for industrial robots, can be applied to challenges in rehabilitation.’
Now, 18 months into the three year project, the researchers have tested the technology on healthy people and proved that it works and now want to carry out trials with local people who have suffered strokes.
Working with stroke patients, the team will look at how electrical stimulation to contract appropriate muscles through electrodes attached to the skin can be controlled to enable stroke patients to successfully perform tasks. The patient will attempt to track a moving target over a two dimensional plane by moving a joy-stick.
The patient’s movement will be measured to detect the tracking error and calculations made to adjust the level and timing of stimulation so that the error is corrected. The ultimate aim is that through repetition, voluntary movement will improve, thus gradually reducing the need for artificial stimulation.
Dr Paul Lewin at ECS commented: ‘This is a very challenging project as it is the first time in Europe that this technology has been applied to humans. With robots, behaviour is entirely predictable, you can make them perform a task perfectly every time. People often reach a natural plateau in their performance, but if you can get them to repeat moves using certain tasks, they have a much better chance of recovery.’
Dr Burridge added: ‘This is a very exciting development of what could prove to be a user friendly way of enabling recovery of movement in patients who are severely disabled.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
