1. Protocolo de intervenção de terapia intensiva para lactentes com assimetria
Resumo Introdução Lesões no sistema nervoso central em desenvolvimento podem causar alterações de tônus, de coordenação e de equilíbrio, assim como assimetria de membros superiores, resultando em limitações funcionais mais evidentes em um hemisfério corporal e restrição na participação social de crianças. Objetivo Partindo do princípio de

2. Effects of aging on interjoint coordination during arm reaching
Abstract Introduction Moving the arm towards an object is a complex task. Movements of the arm joints must be well coordinated in order to obtain a smooth and accurate hand trajectory. Most studies regarding reaching movements address young subjects. Coordination differences in the neural mechanism underlying motor control throughout the life stages is yet

3. Coordenação intermembros no alcance de objetos de lactentes típicos e com síndrome de Down / Interlimb coordination during reaching movements in typical infants and infants with Down syndrome
Research has shown that bimanual actions are demonstrative of the functional brain development; thus it is relevant to investigate how interlimb coordination develops in typically-developing infants, as well as in infants with impaired brain organization, such as in the presence of Down syndrome (DS). Objectives: The aims of this study were as follows: 1) to

4. Determinação da coordenação de nado por meio da análise cinética e cinemática no estilo crawl
A coordenação espaço-temporal dos movimentos dos braços de nadadores competitivos tem demonstrado ser um importante fator ligado a velocidade de nado e ao desempenho desses atletas. Os modelos básicos de coordenação comumente percebidos são: (1) captura - caracterizado pela existência de períodos sem propulsão entre a execução de cada braçada;

5. The oral motor capacity and feeding performance of preterm newborns at the time of transition to oral feeding
The objective of the present study was to determine the oral motor capacity and the feeding performance of preterm newborn infants when they were permitted to start oral feeding. This was an observational and prospective study conducted on 43 preterm newborns admitted to the Neonatal Intensive Care Unit of UFSM, RS, Brazil. Exclusion criteria were the presen

6. Synergistic control of forearm based on accelerometer data and artificial neural networks
In the present study, we modeled a reaching task as a two-link mechanism. The upper arm and forearm motion trajectories during vertical arm movements were estimated from the measured angular accelerations with dual-axis accelerometers. A data set of reaching synergies from able-bodied individuals was used to train a radial basis function artificial neural ne

7. Marcadores genéticos, antropometria e qualidades físicas básicas nos estágios maturacionais de nadadores paraibanos
The aim of this research was to analyse genetic markers, anthropometry and basic physical qualities in the differret stages of sexual maturation in swimmers in Paraíba. It is characterised as a descriptive cross sectional study. The sample was composed of 119 swimmers (males) that were divided among the stages of sexual maturation, from 7 to 17,9 years of a

8. Characterization of chromosome rearrangements in patients with multiple congenital malformation and/or mental retardation (MCM/MR) / Caracterização de rearranjos cromossômicos em pacientes com malformações congênitas múltiplas e/ou retardamento mental (MCA/MR)
Two apparently "de novo" balanced translocations and one duplication of the short arm of chromosome 20 were studied. Our aim was to determine the breakpoints by chromosomal analysis through fluorescentin situ hybridization (FISH) and identify candidate genes and how they were involved with the clinical phenotypes of the patients. Patient 1 carried a duplicat

9. "Comparação de parâmetros cinemáticos da marcha entre indivíduos jovens e idosos em tarefas de ateração do comprimento preferido do passo" / COMPARISON OF GAIT CINEMATIC PARAMETERS BETWEEN YOUNG AND OLD INDIVIDUALS UNDER CHANGES ON PREFERED STEP LENGHT TASKS
The main purpose of this study was verifying the effect of step length restrictions on gait performance of young and old aged, assuming that: (a) when submitted to similar gait conditions, young and old aged presents analogous performance in some gait parameters; (b) the step length restrictions intervene on gait velocity an phase relation between arm and le

10. Analysis of co-ordination between breathing and exercise rhythms in man.
1. The purpose of the present study was to analyse the incidence and type of coordination between breathing rhythm and leg movements during running and to assess the effect of co-ordination on the running efficiency, as well as to compare the results with those found during cycling. 2. The experiments were carried out on thirty-four untrained volunteers exer

11. Performance of a bimanual load-lifting task by parkinsonian patients.
Normal subjects and Parkinsonian patients performed a bimanual load lifting task. In this task, one "postural" forearm, held in a horizontal position while supporting a 1 kg weight, was unloaded either by the experimenter's hand (imposed unloading) or by the subject's other hand in response to a tone burst (voluntary unloading). The variables recorded were r

12. Learning to Control a Brain–Machine Interface for Reaching and Grasping by Primates
Reaching and grasping in primates depend on the coordination of neural activity in large frontoparietal ensembles. Here we demonstrate that primates can learn to reach and grasp virtual objects by controlling a robot arm through a closed-loop brain–machine interface (BMIc) that uses multiple mathematical models to extract several motor parameters (i.e., ha
