Hemi-spatial neglect is an attentional disorder in which the sufferer fails to acknowledge or respond to stimuli appearing in contralesional space. In recent years, it has become clear that a measurable reduction in contralesional neglect can occur during galvanic vestibular stimulation, a technique by which transmastoid, small amplitude current induces(More)
PRIMARY OBJECTIVE Galvanic vestibular stimulation (GVS) involves the delivery of small electrical current to the part of the scalp that overlies the vestibular nerves. A single, brief session transiently reduces certain types of stroke impairment with no reported side-effects. It is anticipated that further reductions will occur if the duration and(More)
BACKGROUND Amyotrophic lateral sclerosis (ALS) is a degenerative disease of motor neurons that causes progressive paralysis and eventually results in death from respiratory failure. Environmental factors that trigger ALS might result in a pattern of geographical clustering of cases. We tested this hypothesis using the South-East England ALS population(More)
BACKGROUND/AIMS We aimed to estimate the incidence and prevalence of amyotrophic lateral sclerosis (ALS) in the South East of England. The reported incidence of ALS varies between 0.44 and 3.2 per 100,000 person years. This can partly be explained by differences in design and diagnostic criteria used. There is little population data concerning England,(More)
Caloric vestibular stimulation (CVS) is commonly used to diagnose brainstem disorder but its therapeutic application is much less established. Based on the finding that CVS increases blood flow to brain structures associated with language and communication, we assessed whether the procedure has potential to relieve symptoms of post-stroke aphasia. Three(More)
—This paper explains the motivations and the goals of the SYSIASS project. This project has three major ambitions: to design intelligent devices for both the assisted navigation of the powered wheelchairs and the secure communication of the data and to design multi-modality human machine interaction. Moreover, the challenge of the project is to take the(More)
OBJECTIVE In recent years it has emerged that the attentional disorder of visuo-spatial neglect can be overcome via artificial stimulation of the balance system. One means of achieving this is via galvanic vestibular stimulation (GVS), a simple procedure in which tiny, electrical currents are discharged to the part of the scalp overlying the vestibular(More)
Two inertial sensor systems were developed for 3-D tracking of upper limb movement. One utilizes four sensors and a kinematic model to track the positions of all four upper limb segments/joints and the other uses one sensor and a dead reckoning algorithm to track a single upper limb segment/joint. Initial evaluation indicates that the system using the(More)
