Standardisiertes postoperatives Schmerztherapieschema in der Orthopädie

2006

In order to treat patients with postoperative acute pain effectively, we have developed a standardised algorithm for analgesia. This process includes three levels and the appropriate supply of medication. The therapy level is defined based on the scale of the operation. Accordingly, the prescription and handling of the pain medication is simplified for the attending physician and nurses. The pain level has to be measured by the nursing staff sing a visual analogue scale (VAS). Thus, the efficiency of the analgesics will be continuously evaluated and controlled. The standardised supply medication can be applied in those cases with pain levels > or = 4 (VAS). It is possible to up- or down-gra…

Indicadores tempranos (0-36 meses) de riesgo de trastorno del espectro autista. Un estudio de revisión.

2018

La prevalencia del trastorno del espectro autista (TEA) ha aumentado de manera muy notable en los últimos años debido fundamentalmente a un aumento del conocimiento sobre el mismo por parte de los profesionales responsables de su identificación y/o diagnóstico.El presente trabajo tiene como objetivo realizar una revisión de los artículos publicados en 2018 que se han propuesto identificar entre los 0 y 36 meses de vida predictores fiables de la posterior aparición del TEA.Se realizó una búsqueda en PsycInfo en la que se localizaron 8 estudios empíricos diseñados para evaluar el poder predictivo de estos indicadores tempranos.En estos estudios se identificaron diferentes síntomas que se cons…

Application of Supervised Machine Learning for Behavioral Biomarkers of Autism Spectrum Disorder Based on Electrodermal Activity and Virtual Reality

2020

[EN] Objective: Sensory processing is the ability to capture, elaborate, and integrate information through the five senses and is impaired in over 90% of children with autism spectrum disorder (ASD). The ASD population shows hyper¿hypo sensitiveness to sensory stimuli that can generate alteration in information processing, affecting cognitive and social responses to daily life situations. Structured and semi-structured interviews are generally used for ASD assessment, and the evaluation relies on the examiner¿s subjectivity and expertise, which can lead to misleading outcomes. Recently, there has been a growing need for more objective, reliable, and valid diagnostic measures, such as biomar…

Visual and postural eye-height information is flexibly coupled in the perception of virtual environments.

2021

We conducted two experiments to investigate how observers integrate postural and visual eye-height information when estimating the layout of interior space. In Experiment 1, we varied postural and visual eye-height information independently of each other in a virtual-reality setup. Observers estimated the width, depth, and height of simulated rooms. All dimensions were perceived as larger when the virtual visual eye-height corresponded to sitting on the floor as compared with standing upright. In contrast, the estimates remained widely unaffected by the observer's physical posture (likewise sitting vs. standing). In Experiment 2, we studied effects of the viewing condition (real vs. virtual…

Cortical and subcortical visual event-related potentials to oddball stimuli in rabbits

2000

We applied repetitive transcranial magnetic stimulation (rTMS) in order to induce interference on visuo-spatial perception in 11 healthy subjects. Subjects performed a visuo-spatial task requiring judgements about the symmetry of prebisected lines. Visual stimuli consisted of symmetrically or asymmetrically transected lines, tachystoscopically presented for 50 ms on a computer-monitor. Performance was examined in basal condition and during rTMS trains of 10 stimuli at 25 Hz, delivered through a focal coil over right or left posterior parietal cortex (P5 and P6 sites) and triggered synchronously with visual stimulus. Randomly intermixed sham rTMS trains were employed to control for non-speci…

Voluntary and Involuntary Attention in Bistable Visual Perception: A MEG Study

2020

In this study, voluntary and involuntary visual attention focused on different interpretations of a bistable image, were investigated using magnetoencephalography (MEG). A Necker cube with sinusoidally modulated pixels' intensity in the front and rear faces with frequencies 6.67 Hz (60/9) and 8.57 Hz (60/7), respectively, was presented to 12 healthy volunteers, who interpreted the cube as either left- or right-oriented. The tags of these frequencies and their second harmonics were identified in the average Fourier spectra of the MEG data recorded from the visual cortex. In the first part of the experiment, the subjects were asked to voluntarily control their attention by interpreting the cu…

Effects of Adding Motor Imagery to Early Physical Therapy in Patients with Knee Osteoarthritis who Had Received Total Knee Arthroplasty

2020

Abstract Objective To investigate the effects of the inclusion of motor imagery (MI) principles into early physical therapy on pain, disability, pressure pain thresholds (PPTs), and range of motion in the early postsurgical phase after total knee arthroplasty (TKA). Methods A randomized clinical trial including patients with knee osteoarthritis who have received TKA was conducted. Participants were randomized to receive five treatment sessions of either physical therapy with or without MI principles in an early postsurgical phase after a TKA (five days after surgery). Pain intensity (visual analog scale [VAS], 0–100), pain-related disability (short-form Western Ontario McMaster Universities…

Blood Alcohol Concentration-Related Lower Performance in Immediate Visual Memory and Working Memory in Adolescent Binge Drinkers

2017

The binge drinking (BD) pattern of alcohol consumption is prevalent during adolescence, a period characterized by critical changes to the structural and functional development of brain areas related with memory and cognition. There is considerable evidence of the cognitive dysfunctions caused by the neurotoxic effects of BD in the not-yet-adult brain. Thus, the aim of the present study was to evaluate the effects of different blood alcohol concentrations (BAC) on memory during late adolescence (18–19 years old) in males and females with a history of BD. The sample consisted of 154 adolescents (67 males and 87 females) that were classified as refrainers if they had never previously drunk alc…

Cognitive impairment in patients suffering from relapsing-remitting multiple sclerosis with EDSS ≤ 3.5

2003

Objectives – Previous papers have mainly demonstrated the presence and the frequency of cognitive impairment in patients suffering from relapsing-remitting multiple sclerosis. The purpose of this study was to investigate subjects with the relapsing-remitting form of the disease and mild clinical disability (EDSS ≤ 3.5), so as to quantify this deficit when the illness does not yet interfere with daily living and the ability to work. Methods – Fifty patients and 50 healthy controls were submitted to a wide neuropsychological battery, including Wechsler Memory Scale – I- (WMS), Benton Visual Retention Test – D- (BVRT), Raven Coloured Progressive Matrices (RCPM), Kohs’ test (KT), Judgement of L…
