OBJECTIVE Previous studies have predominantly investigated the effect of fampridine on lower extremities motor functions while data on its impact on other symptoms of multiple sclerosis (MS) are scarce. The aim of our study was to assess the impact of fampridine on walking, arm/hand function, fatigue, cognitive function, mood and quality of life among responders. METHODS Our prospective non-r...

This paper presents a new approach to the problem of serial binary addition with feed-forward neural networks. It is shown that the serial binary addition, an important component to a number of applications such signal processing, of two n-bit operands with carry can be done by a feed-forward linear threshold gate based network with polynomially bounded weights, i.e. in the order of O(n k), ass...

BACKGROUND Multiple sclerosis (MS) is characterized by demyelinating and degenerative processes within the central nervous system. Unlike conventional MRI,new advanced imaging techniques improve pathological specificity and better highlight the relationship between anatomical damage and clinical impairment. OBJECTIVE To investigate the relationship between clinical disability and both grey (G...

(1) Background: Multiple sclerosis (MS), a chronic progressive neurological disorder which affects the central nervous system (CNS), can result in disorders of all functions controlled by CNS: motor, sensory, cognitive and emotional. Physical therapy (PT), conducted through proprioceptive neuromuscular facilitation (PNF) techniques, be customized to individual patient’s needs has potential impr...

To test a recent suggestion that perceptual learning in visual search is non-specific, two groups of subjects were trained on visual search tasks and tested for transfer of learning to new tasks. One group was trained on parallel ("pop-out") tasks and transferred to serial, conjunction tasks and the other group trained on conjunction and transferred to pop-out. Some (not all) tasks which are in...

Objective To evaluate and compare the effects and outcomes of extracorporeal shock wave therapy (ESWT) and intra-articular injections of hyaluronic acid (HA) in patients with knee osteoarthritis (OA). Methods Of the 78 patients recruited for the study, 61 patients met the inclusion criteria. The enrolled patients were randomly divided into two groups: the ESWT group and the HA group. The ESWT...

In visual search, inefficient performance of human observers is typically characterized by a steady increase in reaction time with the number of array elements-the so-called set-size effect. In general, set-size effects are taken to indicate that processing of the array elements depends on limited-capacity resources, that is, it involves attention. Contrasting theories have been proposed to acc...
