Typical asymmetry in the hemispheric activation during an fMRI verbal comprehension paradigm is related to better performance in verbal and non-verba…

2018

Chronic exposure to seizures in patients with left hemisphere (LH) epileptic focus could favor higher activation in the contralateral hemisphere during language processing, but the cognitive effects of this remain unclear. This study assesses the relationship between asymmetry in hemispheric activation during language fMRI and performance in verbal and non-verbal tasks. Whereas prior studies primarily used fMRI paradigms that favor frontal lobe activation and less prominent activation of the medial or superior temporal lobes, we used a verbal comprehension paradigm previously demonstrated to activate reliably receptive language areas. Forty-seven patients with drug-resistant epilepsy candid…

Age is known to affect prefrontal brain structure and executive functioning in healthy older adults, patients with neurodegenerative conditions and TBI. Yet, no studies appear to have systematically investigated the effect of age on cognitive performance in patients with focal lesions. We investigated the effect of age on the cognitive performance of a large sample of tumour and stroke patients with focal unilateral, frontal (n=68), or non-frontal lesions (n=45) and healthy controls (n=52). We retrospectively reviewed their cross sectional cognitive and imaging data. In our frontal patients, age significantly predicted the magnitude of their impairment on two executive tests (Raven's Advanc…

Padel: A quantitative study of the shots and movements in the high-performance

2013

Padel is a sport that has increasing its importance in recent years. Despite this evolution, there is a lack of scientific papers analyzing padel aspects, specifically about the quantification of movements and shots during match. The purpose of this study was to perform quantitative analyses of movements and shots in padel in order to establish the importance of each type. Twenty male professional players were recorded with a video during ten matches and movements (lateral, head-on and backward displacement, split-steps, jump for a smash, and turns pivoting on the right or left foot) and shots (direct and indirect drive, backhand, smash and lob, and direct volley) were identified, quantifie…

Effect of marathon characteristics and runners' time category on pacing profile.

2020

This study aimed to analyse differences in pacing profiles in four marathon competitions and to explore that pacing per time category. A database of 91,493 runners gathered from 4 different races was analysed (Valencia, Chicago, London and Tokyo Marathon). Participants were categorized in accordance with their completion time. The relative speed of each section for each runner was calculated as a percentage of the average speed for the entire race. In the four marathons studied, the first 5 km differed widely, presenting London the highest relative speeds (5 km: CI95% London vs. Valencia [12.1, 13.6%],

Simulated skiing as a measurement tool for performance in cross-country sit-skiing

2019

The International Paralympic Committee mandates the development of an evidence-based classification system, which requires a measure of performance. Performance in cross-country sit-skiing is mainly dependent on force generated during the poling phase and is enhanced by trunk flexion–extension movements. Since all sit-skiers have neuromuscular impairment, but different ability to control the trunk, this study aimed to verify if simulated action of poling on an adapted ergometer, together with a cluster analysis, could be used for grouping participants with different impairments according to their performance. On the ergometer, eight male and five female participants performed seven poling c…

Use of the Diabetes Risk Score for Opportunistic Screening of Undiagnosed Diabetes and Impaired Glucose Tolerance

2005

OBJECTIVE—To evaluate an opportunistic screening strategy addressed to individuals with one or more cardiovascular risk factor, based on the Diabetes Risk Score (DRS) as the initial instrument, for the identification of individuals with type 2 diabetes or impaired glucose tolerance (IGT). RESEARCH DESIGN AND METHODS—The DRS, a simple self-administered questionnaire, was completed by individuals identified by general practitioners and presenting with one or more cardiovascular risk factor. All patients underwent a 2-h oral glucose tolerance test (OGTT). The optimal DRS cutoff was calculated by applying the receiver-operating characteristic curve. RESULTS—Overall, 1,377 individuals aged betwe…

Match analysis of wheelchair padel players of different functional level

2018

The aim of this study was to quantify the kinematic demands of wheelchair padel and to examine the activity profiles in professional players according to their functional level. Twenty-two elite players classified in functional level groups (from 1 to 4) were video-analysed with a two-dimensional DLT corrected video system across seven matches of a professional tournament. The results showed players covered 729.6 ± 369.9 meters and 238.45 ± 129.45 turns per match during 1128.9 ± 583.04 second of effective playing time at a mean speed of 0.53 ± 0.49 m/s per rally. The WCP players’ functional classification had heavy influence on their activity profiles during matches, with a large associatio…

Contratto ed emergenza sanitaria in Italia

2021

 Questo articolo si propone di analizzare il disastro globale causato dall'epidemia di COVID-19 che ha turbato l'esistenza di quasi tutta l'umanità. Esaminare le significative limitazioni alle libertà individuali e collettive per proteggere la salute pubblica e, in secondo luogo, mitigare il più possibile l'impatto della pandemia sulle attività economiche. L'attenzione dell'articolo si concentrerà esclusivamente sulle norme che impattano sulla disciplina generale delle obbligazioni e dei contratti, tralasciando le importantissime disposizioni in materia di rapporti di lavoro, contratti di mutuo, contratti bancari e assicurativi, ecc. Verificherà fino a che punto la situazione sociale, sanit…

2015

Neuropsychological group study methodology is considered one of the primary methods to further understanding of the organisation of frontal ‘executive’ functions. Typically, patients with frontal lesions caused by stroke or tumours have been grouped together to obtain sufficient power. However, it has been debated whether it is methodologically appropriate to group together patients with neurological lesions of different aetiologies. Despite this debate, very few studies have directly compared the performance of patients with different neurological aetiologies on neuropsychological measures. The few that did included patients with both anterior and posterior lesions. We present the first co…

Comparison of elbow flexor isokinetic peak torque and fatigue index between men and women of different training level

2017

The purpose of the study was to compare elbow flexion peak torque (PT) and fatigue index (FI) during isokinetic concentric contractions in men and women with different training levels. Sixty-eight young men and women were divided into four groups: resistance trained men (RTM), non-resistance trained men (NRTM), resistance trained women (RTW) and non- resistance trained women (NRTW). Participants performed two tests on an isokinetic dynamometer, one to evaluate PT and one to evaluate FI. Significant interactions were found for sex and resistance training status with both PT and FI. In general, resistance-trained subjects had higher PT, and women showed lower PT than men. PT values were 67.12…
