Cerebrovascular accident or stroke in aging population is the primary cause of disability and the second leading cause of death in many countries, including Spain (300,000 people). Arm impairment is common and recovery is partly dependent on the intensity and frequency of rehabilitation intervention. However, physical therapy resources are often limited, so(More)
Allien hand syndrome (AHS) is a rare neurological disorder characterised by uncontrollable and involuntary movement of upper limb. In Fact, the patient feels it as extraneous part of his/her body. From our knowledge, this paper reports the first results of using robot assisted therapy for rehabilitation of patients with AHS syndrome. It is noticeable that(More)
PURPOSE This paper examines the influence of age on several attributes of sensorimotor performance while performing a reaching task. Our hypothesis, based on previous studies, is that aged persons will show differences in one or more of the attributes of sensorimotor performance. PATIENTS AND METHODS Fifty-one subjects (aged 20-80 years) with no known(More)
Nowadays, There are a lot of tools and procedures for the development of computer applications for teaching, entertainment, telecommunications, marketing, design and other more. This paper present a implementation method for developing applications based on virtual reality and procedures physical-haptics, in order to perform rehabilitation tasks, describing(More)
This paper presents the application of an Adaptive Resonance Theory (ART) based on neural networks combined with Fuzzy Logic systems to classify physiological reactions of subjects performing robot-assisted rehabilitation therapies. First, the theoretical background of a neuro-fuzzy classifier called S-dFasArt is presented. Then, the methodology and(More)
This paper presents the development of a rehabilitation robotic platform to research on the adaptation of the complexity of robot assisted therapy and the real-time displays of a virtual reality system in accordance with specific patient requirements. First, a kinematic analysis of the human arm during typical daily activities is presented to justify the(More)
The use of robots in neuro-rehabilitation therapies has increased in recent years. One of them is the PUPArm robot, an end effector robot, that allows the patient recover the lost mobility in the upper limb joints after a stroke. Furthermore, it gives objective information about the improvement the patient's arm to the therapist. However, this data is based(More)
Post-stroke neurorehabilitation based on virtual therapies are performed completing repetitive exercises shown in visual electronic devices, whose content represents imaginary or daily life tasks. Currently, there are two ways of visualization of these task. 3D virtual environments are used to get a three dimensional space that represents the real world(More)
