12/11/2020Even with decades of unprecedented development in computational power, the human brain still holds many advantages over modern computing technologies. Our brains are extremely efficient for many cognitive tasks and do not separate memory and computing, unlike standard computer chips.
10/11/2020At any given moment in time, our brain is involved in various activities. As a result, brain signals contain dynamic neural patterns that reflect a combination of these activities simultaneously. A standing challenge has been isolating those patterns in brain signals that relate to a specific behavior, such as finger movements.
09/11/2020An electroencephalogram (EEG) is a test that is used in cognitive research or to diagnose conditions such as epilepsy and sleep disorders. EEG electrode caps are somewhat difficult to wear, which is why they are only used in laboratories. One viable alternative are measuring devices made of printed electronics. They are more comfortable to wear and allow users to continue their daily activities.
22/09/2020Patients who receive a prosthesis after the amputation of a limb often have to train for weeks or months until they can control the technology and use it in everyday life without problems. At the Medical University of Vienna, the world's first bionic prosthesis has now been developed that has a closed control loop and enables immediate, intuitive use.
03/08/2020Patient monitoring systems in the ICU sound up to 700 alarms on average per patient per day, which boils down to one alarm every two minutes. An excessive number of them are false alarms. This generates vast amounts of data, which can make it difficult for doctors and nurses to identify the most critical alarms to manage. It also has a negative effect on the treatment of intensive care patients.
02/06/2020Stroke can affect anyone – older as well as younger people. The minutes after the stroke determine whether disability or death is the result. Only if acute care, inpatient treatment and rehabilitation are carried out in a targeted and effective manner, the chances are greater that only minor damage remains or that impairments even recede.
02/06/2020"Time is brain!" – a fundamental rule in stroke care because time is of the essence when brain regions are undersupplied with oxygen and glucose. If circulation is not restored quickly, brain damage can be permanent. However, the key point here is not just to "be fast", but also to "use the time to treat stroke effectively".
25/02/2020Neurological disorders like Parkinson's are often diagnosed once the disease has already progressed to a later stage. The VAFES project was initiated to facilitate an early detection. Sensor technology and VR are used in the creation of a playful test system.
01/10/2019Pneumonia, COPD or cystic fibrosis – people with such lung diseases have to consult their doctor regularly. Little children have to undergo certain measurements by the doctor, too. In order to save people`s need to visit a doctor, telemedicine offers many ways to do examinations at home.
02/09/2019Radiology is a field that produces large volumes of data, which can no longer be managed without the help of intelligent systems. This is especially true when it comes to the interpretation of medical images. While this takes physicians years of training and experience, several hours of work and the highest level of concentration, AI only requires a few seconds to accomplish the same task.
02/09/2019Artificial intelligence is no longer a dream of the future in medicine. Many studies and initial application examples show that it sometimes achieves better results than human physicians. At Jena University Hospital, the work with AI is already lived practice. It is the first institution in the world to use algorithms in radiological routine to reconstruct CT images.
02/09/2019In modern medicine, especially in the field of imaging, huge amounts of data are produced – so much that radiologists can hardly keep up with diagnosing the images. Artificial Intelligence could be the solution to this problem. But how exactly can it help in this task? How can man and machine work together? And what else will be possible in the future with the support of intelligent systems?
02/09/2019More patients, more examinations, more CT images – in radiology there is too much work for too few physicians. CT scans are evaluated in the shortest possible time, which leads to anomalies being overlooked. Artificial intelligence, on the other hand, works with constant speed and performance, which is why radiological routine increasingly relies on its support.
01/07/2019Amateur and professional athletes are susceptible to sports injuries, balance disorders or deficits in motor function and posture. Prevention and the right training can help avoid these incidents, while targeted therapy can support a return to sports after an injury.

Laser ablation for epilepsy is a new, catheter-based surgical procedure that is now also available in Europe, preventing patients from having to undergo open brain surgery.
03/06/2019For most people, enjoying a good quality of life means having the ability to move freely, safely and independently. Intensive and costly rehabilitation is needed if this is no longer an option after a stroke for example. We are introducing some projects that deliver innovative robotic solutions.
03/06/2019Humans are living longer than ever but still want to continue to live independently as they age. Meanwhile, our motor and cognitive abilities decline as we age, sometimes as the effects of a stroke. The number of people in need of long-term care is growing at breakneck speed. At the same time, fewer and fewer young people choose stressful careers as caregivers.
03/06/2019They work with power, precision and tirelessly. This makes robots an ideal instrument for rehabilitation. In gait or motor training, movement sequences must be repeated thousands of times so that they can be learnt anew. What tires the patient and costs the therapist's time can easily be managed by robot-assisted systems. Learn more about the possibilities of robotics in rehabilitation.
03/06/2019It 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.
08/04/2019Cardiac arrhythmia is a group of conditions where nerve cells trigger uncontrolled contractions of the heart muscle. They are treated with either medicine or catheter ablation of the tissue. In an interdisciplinary collaboration, cardiologists and radiotherapists took a different approach and used high-precision radiation therapy to treat a patient for whom the other options proved unfeasible.
01/04/2019In an ischaemic stroke, rapid treatment is essential. In this moment good imaging data is particularly important to enable doctors to make the best possible decision for therapy. Modern CT scanners are increasingly being used to assess stroke patients because they can show the blood flow to the brain over time.
01/04/2019All information from our body and the environment converges in our brain and is transformed into reactions in milliseconds. It is essential for medicine and research to know what our switching centre looks like. Functional methods are used to observe it more closely during work.
01/04/2019Our brain is the command center of our body. This is where all information and impressions are collected and converted into responses and movements. Modern imaging techniques offer physicians and researchers unique insights into the actions of the human central nervous system. The functional imaging technique allows them to watch our brain in action.
01/04/2019A surgery already begins before the patient is lying on the operating table – namely with the planning. For example, if brain surgery is imminent, the brain must first be mapped. This makes the activity level of certain brain areas visible. Functional magnetic resonance imaging makes this possible.
10/12/2018So 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.
03/12/2018The treatment for many neurological and mental disorders is far from being an easy feat. Drug therapies always require accurate medication adjustments, while brain surgeries have the potential for risks and complications. Non-invasive brain stimulation takes a different approach: magnetic fields and electric current change the activities in the brain - without putting the patient at risk.
03/12/2018According to estimates, every third person in the world suffers from chronic pain. The most common discomforts include back pain, headaches, and nerve pain. For many sufferers, the pain is so severe that it impacts their job, social life or mind. The pain has its own clinical significance and must be treated – with electric current for example.
22/11/2018Every year between 250.000 and 500.000 people suffer a spinal cord injury, MoreGrasp is intended to make their lives easier.
