Stimuli and desire linked to help stroke patients

15.02.2005


Innovative research restores hand function



Once-paralyzed stroke victims are regaining arm and hand functions thanks to an innovative treatment developed by University of Toronto and Toronto Rehabilitation Institute researchers.

The treatment, outlined in the January Neuromodulation, uses a neuroprosthesis that stimulates muscles with electrical pulses, mimicking the intricate movements along the hand and arm. Simultaneously, the patient concentrates on the movement itself, gradually reconnecting the damaged neuronal connection with the patient’s free will.


"Most therapies do not actively encourage the patient to think about what they’re doing, so there is no connection to the brain to do it," says the paper’s lead author, Professor Milos Popovic of U of T’s Institute of Biomaterials and Biomedical Engineering (IBBME) and the Toronto Rehabilitation Institute. "We hypothesized that the central nervous system has reserves, and even if one part of the brain has been damaged, another reserve can be tapped into to produce movement."

In the study, Popovic and colleagues did a randomized clinical trial on patients who had lost hand and arm movement; 85 per cent of stroke patients never recover movement. The control group received standard physiotherapy and occupational therapy, while the treatment group trained with the neuroprosthesis in addition to the standard therapy. "In the treatment group, we showed that after 16 weeks, we can restore some of their reaching and grasping functions," says Popovic. "This progress did not appear in the control group. It’s all about linking the desire to heal with the stimulated movements."

Popovic soon hopes to find an industry partner to build the technologically advanced neuroprosthesis and to persuade other institutions to use the approach.

Im Focus: Optical Nanoscope Allows Imaging of Quantum Dots

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.

Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
