Assistive technology is dedicated to people who suffers from disabilities or pathologies that limit their daily life. It provides support in alternative communication, accessibility, mobility and cognitive domains. An example of this type of technology is the electric wheelchair that allows the person to move more freely and independently. However, most(More)
Tremor is the most common movement disorder and differs from other disorders by its repetitive, stereotyped movements, with regular frequency and amplitude. The three most frequent pathological forms of it are the essential tremor (ET), the Parkinson's disease (PD) tremor, and the enhanced physiological tremor. The ET and PD tremor affect the older(More)
Virtual reality technologies enable the creation of environments for the assessment and training of motor deficits using enhanced feedback. This paper reports the development of a virtual reality environment applied toelectromyographic (EMG) biofeedbaclifor motor rehabilitation. It was modeled a 3D arm controlled by the EMG signals from brachial biceps(More)
Accidents happen and unfortunately people may loose part of their body members. Studies have shown that in this case, most individuals suffer physically and psychologically. For this reason, actions to restore the patient's freedom and mobility are imperative. Traditional solutions require ways to adapt the individual to prosthetic devices. This idea is(More)
Computer-based training systems have been widely studied in the field of human rehabilitation. In health applications, Virtual Reality presents itself as an appropriate tool to simulate training environments without exposing the patients to risks. In particular, virtual prosthetic devices have been used to reduce the great mental effort needed by patients(More)
Augmented Reality is a technology which provides people with more intuitive ways of interaction and visualization, close to those in real world. The amount of applications using Augmented Reality is growing every day, and results can be already seen in several fields such as Education, Training, Entertainment and Medicine. The system proposed in this(More)
Differential Evolution (DE) is a tool for efficient optimisation, and it belongs to the class of evolutionary algorithms, which include Evolution Strategies and Genetic Algorithms. DE algorithms work well when the population covers the entire search space, and they have shown to be effective on a large range of classical optimisation problems. However, an(More)
Spasticity is a motor disorder that affects over 12 million people worldwide. Its pathophysiology is rather complex and might be caused by cortical problems or spinal cord injury, for example, and involves different circuitries and networks. The measurement of spasticity is very important for providing better support for the patients, both in diagnosis and(More)
