Production of voluntary movements relies critically on the functional integration of several motor cortical areas, such as the primary motor cortex, and the spinal circuitries. Surprisingly, after almost 40 years of research, how the motor cortices specify descending neural signals destined for the downstream interneurons and motoneurons has remained(More)
BACKGROUND Six months after a stroke, the hemiplegic arm often remains compromised. More innovative approaches to motor rehabilitation are needed. OBJECTIVE The authors compared a motor learning-based approach in a virtual environment with more conventional upper extremity therapy in a pilot trial. METHODS This prospective, single-blinded, randomized(More)
Recent evidence has demonstrated the efficacy of Virtual Reality (VR) for stroke rehabilitation nonetheless its benefits and limitations in large population of patients have not yet been studied. To evaluate the effectiveness of non-immersive VR treatment for the restoration of the upper limb motor function and its impact on the activities of daily living(More)
The aim of the present study is to compare different visual elicitation paradigms exploitable in a Virtual Environment in order to establish whether the BCI is affected by the structure of the elicitation paradigm, the modalities of stimulus presentation, and the complexity of stimulus recognition and semantic processing. We have developed a device which(More)
BACKGROUND Memory decline is a prevalent aspect of aging but may also be the first sign of cognitive pathology. Virtual reality (VR) using immersion and interaction may provide new approaches to the treatment of memory deficits in elderly individuals. OBJECTIVE The authors implemented a VR training intervention to try to lessen cognitive decline and(More)
Background. Haptic robots allow the exploitation of known motor learning mechanisms, representing a valuable option for motor treatment after stroke. The aim of this feasibility multicentre study was to test the clinical efficacy of a haptic prototype, for the recovery of hand function after stroke. Methods. A prospective pilot clinical trial was planned on(More)
BACKGROUND AND PURPOSE Reinforced feedback in virtual environment (RFVE) therapy is emerging as an innovative method in rehabilitation, which may be advantageous in the treatment of the affected arm after stroke. The purpose of this study was to investigate the impact of assisted motor training in a virtual environment for the treatment of the upper(More)
This study describes the case of a global alexic patient with a severe reading deficit affecting words, letters and Arabic numbers, following a left posterior lesion. The patient (VA) could not match spoken letters to their graphic form. A preserved ability to recognize shape and canonical orientation of letters indicates intact access to the representation(More)
The disability deriving from stroke impacts heavily on the economic and social aspects of western countries because stroke survivors commonly experience various degrees of autonomy reduction in the activities of daily living. Recent developments in neuroscience, neurophysiology and computational science have led to innovative theories about the brain(More)
