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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
