Effect of Isometric Upper-Extremity Exercises on the Activation of Core Stabilizing Muscles
2007
Abstract Tarnanen SP, Ylinen JJ, Siekkinen KM, Malkia EA, Kautiainen HJ, Hakkinen AH. Effect of isometric upper-extremity exercises on the activation of core stabilizing muscles. Objective To evaluate whether isometric exercises for the upper extremities could sufficiently activate core stabilizing muscles to increase muscle strength. Design Cross-sectional study. Setting Department of physical medicine and rehabilitation at a Finnish hospital. Participants Healthy adult women (N=20). Interventions Not applicable. Main Outcome Measures Peak isometric strength of the back and abdominal muscles was measured and relative loading in 5 test exercises was evaluated by surface electromyography. Re…
Posturographic analysis of balance control in patients with haemophilic arthropathy
2007
Summary. Musculoskeletal disorders in haemophiliacs represent the highest percentage of lesions, giving rise to haemophilic arthropathy (HA) which predominantly affects lower limbs, influencing postural control, standing and walking. Leading a sedentary lifestyle seems to influence strength and muscular resistance in haemophiliacs which, in turn, are related to articular stability and the prevention of articular degenerative processes. The objective of this work was to study alterations in balance to subsequently evaluate the appropriate therapeutics and how this influences the development of arthropathy. Twenty-five haemophiliacs with HA, 25 haemophiliacs without HA (NHA) and 25 healthy c…
In the presence of IL-21 human cord blood T cells differentiate to IL-10-producing Th1 but not Th17 or Th2 cells.
2012
Abstract IL-21, a member of the IL-2 cytokine family, is mainly produced by activated CD4+ T cells and controls the activity of immune and also non-immune cells. As a pleiotropic cytokine, IL-21 acts on both innate and adaptive immune responses, suggesting that IL-21 may be a master regulator of the T-cell-dependent adaptive immune response. Although IL-21 is described as mostly promoting inflammation, evidence also suggests inhibitory effects of IL-21. However, its role, particularly in the human neonatal immune system, has not been detailed so far. Here, we assessed the effect of IL-21 in the specific context of the neonatal immune response and delineated differences between the human new…
Discourse Analytic Study of Counseling Sessions in Stroke Physiotherapy
2006
Studies on the interaction between physiotherapists and patients during treatment sessions have found low levels of communicative participation by patients and lack of direct influence by patients on the content of their treatment. This article reports the results of 7 counseling sessions in which physiotherapists and patients with stroke and their caregivers discussed the patients' postural control and balance, which had been tested and videotaped at different stages of the rehabilitation process. The physiotherapists' discourses relating to the videotaped test performances were either brief comments on the patient's performance or critical appraisals with references to difficulties encoun…
Children’s Diet during the Early Stages of the Nutritional Transition. The Foundlings in the Hospital of Valencia (Spain), 1852–1931
2021
The nutritional transition brought about profound changes in the nutrition of the European population in the 19th and 20th centuries. The predominant consumption of cereals gave way to kilocalorie-, protein-, vitamin- and mineral-rich diets that involved a greater intake of animal products. However, not all population groups underwent this transition at the same pace
AEROgui: A graphical user interface for the optical properties of aerosols
2014
Atmospheric aerosols have an uncertain effect on climate and serious impacts on human health. The uncertainty in the aerosols' role on climate has several sources. First, aerosols have great spatial and temporal variability. The spatial variability arises from the fact that aerosols emitted in a certain place can travel thousands of kilometers, swept by the winds to modify the destination region's climate. The spatial variability also means that aerosols are inhomogeneously distributed in the vertical direction, which can lead to a differential effect on the energy balance depending on the aerosols' altitude. On the other hand, aerosols experience physical and chemical transformations in th…
Risk of drug-related falls among noninstitutionalized older adults
2017
To determine the number of drugs taken per day, which represents a risk factor for falls among noninstitutionalized older adults with a history of falls in the last year.This was a descriptive study that used random sampling and the following measurement instruments: the WHO questionnaire for the study of falls in older adults, gait scale and geriatric depression scale and gait and balance. Univariate and bivariate analysis, nonparametric chi-squared test, and binary logistic regression were performed using the SPSS statistical program version 21.0.214 individuals participated in the study. Those who took ≥ 4 drugs presented higher risk of falling, p=0.010 OR=4.034. The same was not true fo…
The reliability, distribution, and responsiveness of the Postural Control and Balance for Stroke Test
2005
Abstract Pyoria O, Talvitie U, Villberg J. The reliability, distribution, and responsiveness of the Postural Control and Balance for Stroke Test. Objectives To determine the inter- and intrarater reliability of the Postural Control and Balance for Stroke (PCBS) test and to assess its distribution and responsiveness to changes during 1-year follow-up. Design Intrarater reliability of the PCBS test was assessed by comparing the repeat ratings of videotaped test performances by each of the 5 raters. Interrater reliability was assessed by comparing the ratings of the videotaped test performances between the raters. Setting Hospital neurologic ward and outpatient department of physiotherapy as w…
Evaluation of the postural stability of elderly persons using time domain signal analysis
2012
A force platform is widely used in the evaluation of postural stability in man. Although an abundance of parameters are typically retrieved from force platform data, no uniform analysis of the data has been carried out. In general, the signal analysis does not analyze the underlying postural event, i.e., whether the signal consists of several small corrections or large excursions. In the present work, we studied the postural stability of 4589 elderly persons from Iceland on a force platform under visual and non-visual conditions during stance on a solid surface. We analyzed the internal relationship between frequently used time domain variables. In addition, we conducted a factor analysis u…
Contagion and Bank Runs in a Multi-Agent Financial System
2012
In this work we explore contagion from one institution to another that can stem from the existence of a network of financial contracts. In fact, in modern financial systems, an intricate web of claims and obligations links the balance sheets of a wide variety of intermediaries (banks, for instance) into a network structure of interdependencies that have created an environment for feedback elements to generate amplified responses to shocks to the financial system. Small shocks, which initially affect only a few institutions, can indeed spread by contagion to the rest of the financial sector and cause a crisis in the connected intermediaries. Whether the financial crisis does spread depends c…
