Field location and player roles as constraints on emergent 1-vs-1 interpersonal patterns of play in football
2017
This study examined effects of player roles on interpersonal patterns of coordination that sustain decision-making in 1-vs-1 sub-phases of football in different field locations near the goal (left-, middle- and right zone). Participants were fifteen U-16 yrs players from a local competitive amateur team. To measure interpersonal patterns of coordination in the 1-vs-1 dyads we recorded: (i) the relative distance value between each attacker and defender to the centre of the goal, and (ii), the relative angle between the centre of the goal, each defender and attacker. Results revealed how variations in field locations near the goal (left-, middle- and right-zones) constrained the relative dist…
Altered postural control and stability in cirrhotic patients with minimal hepatic encephalopathy correlate with cognitive deficits
2017
Background & Aims: Cognitive dysfunction in cirrhotic patients with minimal hepatic encephalopathy (MHE) is associated with falls. Alterations in postural control and stability could contribute to increase falls risk in these patients. We aimed to assess whether postural control and direction-specific limits of stability are altered in cirrhotic patients with MHE compared to patients without MHE and controls. We also assessed if alterations in postural control correlate with neurological impairment and/or blood biomarkers. Methods: Posturography analysis, attention Stroop test and bimanual and visuo-motor coordination tests were performed in 18 controls, 19 patients with cirrhosis without M…
Mathematical performance predicts progress in reading comprehension among 7-year olds
2005
The aim of this longitudinal study was to investigate cross-lagged relationships between mathematical performance and reading comprehension during the first and second years of primary school. 114 Finnish-speaking children were examined six times on mathematics and reading comprehension during Years 1 and 2. At the beginning of Year 1, they were also tested on initial mathematics and reading skill, general concept ability and visual-motor skills. The results showed, firstly, that mathematics and reading comprehension were highly associated with each other across both years. Secondly, mathematical performance predicted subsequent reading comprehension during the first year rather than vice v…
The New Patterns study: coordinated measures to combat child poverty
2020
Background Child poverty rates are rising in Norway with potential negative consequences for children. Services for families with low income are often fragmented and poorly integrated, and few coordinated initiatives have been implemented and evaluated in Norway. Aims: The aim of the current study is to evaluate how integrated and coordinated services provided over a prolonged period by a family coordinator are related to changes across a wide range of health, wellbeing and home environment indicators for the participants. Methods: The study uses a mixed methods approach utilising survey and register data, as well as information from interviews and shadowing, to document and evaluate outcom…
Reliability and validity of the Finnish version of the motor observation questionnaire for teachers.
2017
Objectives: Observational screening instruments are often used as an effective, economical first step in the identification of children with Developmental Coordination Disorder (DCD). The aim was to investigate the psychometric properties of the Finnish version of the Motor Observation Questionnaire for Teachers (MOQ-T-FI).Methods: The psychometric properties were tested using two separate samples (S1: age range 6-12, M 9y 5mo, females 101, males 92; S2: age range 6-9, M 7y 7mo, females 404, males 446). Teachers completed the MOQ-T-Fl in both samples, and in sample 2 teachers' ratings were compared to student's performance on the Movement Assessment Battery for Children-Second Edition (MABC…
Anticonvulsant effects of carbenoxolone in genetically epilepsy prone rats (GEPRs).
2004
Carbenoxolone (CBX), the succinyl ester of glycyrrhetinic acid, is an inhibitor of gap junctional intercellular communication. Systemic administration of CBX was able to decrease the seizure severity score and to increase the latency time of seizure onset in genetically epilepsy prone rats (GEPRs). In particular, intravenous or intraperitoneal administration of carbenoxolone (5-30 mg/kg) produced a dose-dependent and significant reduction in the clonic and tonic phases of the audiogenic seizures in GEPRs. The anticonvulsant doses were not associated with an impairment of motor coordination. The bilateral microinjection of CBX (0.001-0.50 microg/0.5 microl) into the inferior colliculi, the s…
Impact of a multimodal exercise program on tibial bone health in adolescents with Development Coordination Disorder : an examination of feasibility a…
2020
Objectives: Developmental coordination disorder (DCD) compromises bone health purportedly due to lower levels of physical activity. The potential of an exercise intervention to improve bone health parameters in adolescents with DCD has not previously been studied. This study thus aimed to determine the impact of a multimodal exercise intervention on bone health in this population at-risk of secondary osteoporosis. Methods: Twenty-eight adolescents (17 male, 11 female) aged between 12-17 years (Mage=14.1) with DCD participated in a twice weekly, 13-week generalised multimodal exercise intervention. Peripheral quantitative computed tomography scans of the tibia (4% and 66%) were performed ove…
Difference in physical fitness in children with initially high and low gross motor competence: A ten-year follow-up study
2018
Abstract The aim of the study was to investigate the difference in relative physical fitness between children with initially high and low gross motor competence in a ten-year prospective study. A sample of 49 children from a local primary school was tested on gross motor competence and physical fitness in 1st grade (5/6 years old). The children were tested again in 2nd (motor competence only), 7th, and 10th grade (15/16 years old). The sample was divided into two groups; initially high and low gross motor competence, according to score (median-split) on the Korperkoordinationstest fur Kinder-test battery in 1st grade. Results suggested that the initially high gross motor competence-group pe…
Genome-wide association study of motor coordination problems in ADHD identifies genes for brain and muscle function.
2012
Item does not contain fulltext OBJECTIVES: Motor coordination problems are frequent in children with attention deficit/hyperactivity disorder (ADHD). We performed a genome-wide association study to identify genes contributing to motor coordination problems, hypothesizing that the presence of such problems in children with ADHD may identify a sample of reduced genetic heterogeneity. METHODS: Children with ADHD from the International Multicentre ADHD Genetic (IMAGE) study were evaluated with the Parental Account of Children's Symptoms. Genetic association testing was performed in PLINK on 890 probands with genome-wide genotyping data. Bioinformatics enrichment-analysis was performed on highly…
''Active Collisions in Altered Gravity Reveal Eye-Hand Coordination Strategies''
2012
White, Olivier | Lefevre, Philippe | Wing, Alan M. | Bracewell, R. Martyn | Thonnard, Jean-Louis; International audience; ''Most object manipulation tasks involve a series of actions demarcated by mechanical contact events, and gaze is usually directed to the locations of these events as the task unfolds. Typically, gaze foveates the target 200 ms in advance of the contact. This strategy improves manual accuracy through visual feedback and the use of gaze-related signals to guide the hand/ object. Many studies have investigated eye-hand coordination in experimental and natural tasks; most of them highlighted a strong link between eye movements and hand or object kinematics. In this experime…
