Psycho-Social Factors in Patients with Cardiovascular Disease Attending a Family-Centred Prevention and Rehabilitation Programme: EUROACTION Model in…
2021
Background: Coronary heart disease (CHD) persists as the leading cause of death worldwide. Cardiovascular prevention and rehabilitation (CVPR) has an interdisciplinary focus, and includes not only in physiological components, but it also addresses psycho-social factors. Methods: The study analysed the Spanish psycho-social data collected during the EUROACTION study. In Spain, two hospitals were randomised in the Valencia community. Coronary patients were prospectively and consecutively identified in both hospitals. The intervention hospital carried out a 16-week CVPR programme, which aimed to assess illness perceptions and establish healthy behaviours in patients and their partners. Results…
Effect of Manual Therapy and Splint Therapy in People with Temporomandibular Disorders: A Preliminary Study
2020
Background: Isolated manual therapy techniques (MT) have shown beneficial effects in patients with temporomandibular disorders (TMD) but the effect of the combination of such techniques, together with the well-stablished splint therapy (ST) remains to be elucidated. Objective: This study was conducted to ascertain whether a combined program of MT techniques, including intraoral treatment, plus traditional ST improves pain and clinical dysfunction in subjects with TMD. Methods: A preliminary trial was conducted. 16 participants were assigned to either the MT plus ST-Experimental Group (EG, n = 8) or the ST alone&mdash
Anodal transcranial direct current stimulation over the right hemisphere improves auditory comprehension in a case of dementia.
2017
Background Noninvasive transcranial stimulation methods have been increasingly employed in order to improve cognitive performance in neurological patients. In previous studies with both stroke patients and healthy subjects, noninvasive stimulation of temporal-parietal regions and their homologue produced an improvement in linguistic tasks. Objective The aim of the current study was to evaluate if anodal transcranial direct current stimulation (tDCS) over Brodmann areas 39/40 (angular and supramarginal gyri) could promote the recovery of linguistic functions, in particular comprehension and naming, in a single patient affected by dementia. Methods Three preliminary explorative single session…
RELACIÓN ENTRE EL PROCESAMIENTO SENSORIAL Y LA SEVERIDAD DE LA SINTOMATOLOGÍA EN UNA MUESTRA DE NIÑOS CON TEA
2014
Abstract:RELATION BETWEEN SENSORY PROCESSING AND SEVERITY OF SYMPTOMS IN A SAMPLE OF CHILDREN WITH ASDThe new DSM-5 criteria include the alterations of sensory perception as a new diagnostic criterion to consider in the ASD population. Considering the inclusion of this new approach, the purpose of this study is to compare the features of sensory processing among a group of children (from 5 to 8 years old) with and without ASD. In addition to this, in the case of the ASD group, possible relationships between the sensory processing and the severity of symptoms, assessed by the GARS-2, are analyzed. To do this, the parents of 84 children (41 with ASD diagnosis and 43 with typical development),…
Concept of an extracellular regulation of muscular metabolic rate during heavy exercise in humans by psychophysiological feedback.
1996
Efferent motor signals to skeletal muscles concern not only the space/ time pattern of motion, but also the setting of muscular performance and through this the control of the current metabolic rate. For an optimal adjustment of metabolic rate during heavy exercise-e.g. in athletic competitions-a feedback control system must exist, including a programmer that takes into consideration a finishing point (teleoanticipation). The presented experiments, using Borg's scale, indicate the existence and functioning of a system for optimal adjustment of performance during heavy exercise and the relevance of teleoanticipatory effects. Thus motor learning includes not only somatosensory control, but al…
New intraocular lens for achromatizing the human eye.
2007
To describe the design of a new intraocular lens (IOL) capable of correcting spherical and chromatic aberrations when implanted in the human eye.University of Murcia, Murcia, and University of Valencia, Valencia, Spain.A hybrid singlet achromatic IOL was designed. The IOL has a combination of a refractive and a diffractive surface, with 1 of the surfaces being aspherical. Optical simulations were used to model the polychromatic modulation transfer function (MTF) in pseudophakic eyes to explain the differences in optical quality afforded by the achromatic IOL. Parameters such as focus shift, optical path difference, through-focus, and robustness to tilt and decentering of achromatic IOLs wer…
A Unified Theory of Psychophysical Laws in Auditory Intensity Perception.
2020
Psychophysical laws quantitatively relate perceptual magnitude to stimulus intensity. While most people have accepted Stevens's power function as the psychophysical law, few believe in Fechner's original idea using just-noticeable-differences (jnd) as a constant perceptual unit to educe psychophysical laws. Here I present a unified theory in hearing, starting with a general form of Zwislocki's loudness function (1965) to derive a general form of Brentano's law. I will arrive at a general form of the loudness-jnd relationship that unifies previous loudness-jnd theories. Specifically, the "slope," "proportional-jnd," and "equal-loudness, equal-jnd" theories, are three additive terms in the ne…
Brain stimulation procedures for treatment of contralesional spatial neglect
2011
The application of brain stimulation techniques for modulation of cortical excitability changes underlying spatial neglect following right-brain-damage has been the first application of brain stimulation in the rehabilitation setting. Several factors concur in making neglect a prototype of cognitive disorders that can be modulated by brain stimulation: 1) neglect is highly lateralized deficit, 2) neglect is a network disorder in which lesion of a network node impacts affects excitability of intrahemispehric and interhemispheric connections, and 3) lesions of the right hemisphere, the most frequent cause of neglect, are associated with a transcallosally mediated increase of facilitation of t…
Etnoargumentos y discursos comunes en torno a un megaevento deportivo: La 32ª America's Cup vista por la sociedad anfitriona
2013
Entre 2004 y 2007, se celebró en Valencia, España, la 32ª edición de la America’s Cup, el evento deportivo más antiguo, el más prestigioso del mundo de la vela y uno de los de mayor impacto económico y mediático que existe en la actualidad a escala internacional. Aunque era la primera vez en que tal evento se celebraba en Europa los resultados fueron unánimemente considerados como un éxito de organización, asistencia y audiencias. Este artículo aborda un aspecto menos explorado de los megaeventos deportivos: las percepciones que sobre el mismo elaboraron los propios residentes. Para ello se realizó una investigación cualitativa –consistente en veinte entrevistas– que ha permitido identifica…
Inattentional deafness under dynamic musical conditions
2009
While inattentional blindness is a modern classic in attention and perception research, analogous phenomena of inattentional deafness are less well-known. In music, inattentional deafness has never been demonstrated under controlled experimental conditions, despite of indirect evidence for related effects. We tested inattentional deafness with real music in both musicians and non-musicians. Participants listened to the first 1’50” of Richard Strauss’ Thus Spake Zarathustra, with the experimental group having the task of counting the number of tympani beats and the control group just listening. The unexpected event was an e-guitar solo during the last 20s of this sequence. In Study 1, among …
