Freezing of gait is a phenomenon common in Parkinson's patients and significantly affects quality of life. Sensory cues have been known to improve walking performance and reduce freezing of gait. Visual cues are reported to be particularly effective for this purpose. So far, sensory cues have generally been provided continuously, even when currently not(More)
OBJECTIVE Hypobaric hypoxia, physical and psychosocial stress may influence key cardiovascular parameters including blood pressure (BP) and pulse pressure (PP). We investigated the effects of mild hypobaric hypoxia exposure on BP and PP reactivity to mental and physical stress and to passive elevation by cable car. METHODS 36 healthy volunteers(More)
The human brain consists of millions of neural nerve cells being interconnected and firing in parallel in order to process information. A fundamental question is how this parallel neuron-firing can result in a unified experience. This is the so-called binding problem--a problem that is one of today's key questions about brain function and that has puzzled(More)
Artificial Intelligence (AI) is a branch of computer science concerned with making computers behave like humans. At least this was the original idea. However, it turned out that this was no easy task to solve. This article aims to give a comprehensible review on the last 60 years of artificial intelligence taking a philosophical viewpoint. It is outlined(More)
In robotic rehabilitation, the way of attaching the robotic device to the users' limb constitutes a crucial element of product quality, particularly for assuring good fitting, comfort, accuracy, usability, and safety. In this article, we present a new technological concept — ‘Variable Stiffness Structure’ — allowing for an(More)
