1. 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

2. Protocolo clínico para avaliação de ajustes posturais antecipatórios: desenvolvimento e validação / Clinical protocol for assessment of anticipatory postural adjustments: development and validation
Evaluating motor control is a recurrent practice in physiotherapeutic routine, in which physiotherapist analyzes anticipatory postural adjustments (APAs) and compensatory postural adjustments (CPAs). APAs, subject of interest, precede planned postural perturbation and minimized them through corrections to maintaining the stability. It is known the relationsh

3. Análise cinesiológica e biomecânica de atividades de manuseio de carga.
As atividades de manuseio de carga geram grandes sobrecargas ao sistema músculoesquelético, aumentando com isso os riscos de lesões. O fato dessas atividades de manuseio serem consideradas de risco fez com que muitos estudos fossem realizados considerando situações de levantamento, abaixamento, puxar e empurrar cargas. Os resultados obtidos certamente p

4. Animação facial sincronizada com a fala : visemas dependentes do contexto fonetico para o portugues do Brasil / Speech synchronized facial animation: phonetic context dependent visemes for Brazilian portuguese
Computer facial animation refers to the techniques for specifying and controlling the positioning, motion, and appearance of a synthetic face over time. Speech synchronized facial animation addres-ses the control of a virtual face conducted by the phonetic events of an utterance. Such control implies the manipulation of the virtual face synchronized and coor

5. Tempo de reação, tempo de movimento e aquisição de timing antecipatorio em idosos
Motor performance is related to muscular factors, more in terms of control rather than strength, but it seems particularly related to information processing speed. During the aging process, motor response time increases due to organism structural and functioning modifications. Nevertheless, the identificationof factors involved in this response temporal slow

6. Anticipatory postural adjustments during self inflicted and predictable perturbations in Parkinson's disease.
This study investigated the relation between impaired anticipatory postural adjustments and bradykinesia in Parkinson's disease. Patients with Parkinson's disease and age matched controls stood on a platform. In one series of experiments, they performed fast, discrete shoulder flexion or extension movements. In another series, they were required to press a t

7. Posturo-kinetic organisation during the early phase of voluntary upper limb movement. 1. Normal subjects.
The nature and organisation of anticipatory postural adjustments (APA) associated with the early phase of a voluntary upper limb movement were studied. Upper limb elevations, performed at maximal velocity, were studied according to three conditions: bilateral flexions (BF) and unilateral flexions without and with an additional inertia (respectively OUF and I

8. Human smooth and saccadic eye movements during voluntary pursuit of different target motions on different backgrounds.
Horizontal and vertical eye movements of ten human subjects were recorded with a scleral induction-coil technique during voluntary pursuit of sinusoidal, triangular and pseudo-random target motions of different frequency, amplitude and dimensionality upon a dark, diffuse or structured background. Data processing included separation of the composite eye movem

9. On the predictive control of foveal eye tracking and slow phases of optokinetic and vestibular nystagmus.
Smooth pursuit and saccadic components of foveal visual tracking as well as more involuntary ocular movements of optokinetic (o.k.n.) and vestibular nystagmus slow phase components were investigated in man, with particular attention given to their possible input-adaptive or predictive behaviour. Each component in question was isolated from the eye movement r

10. Learning of a Sequential Motor Skill Comprises Explicit and Implicit Components That Consolidate Differently
The ability to perform accurate sequential movements is essential to normal motor function. Learning a sequential motor behavior is comprised of two basic components: explicit identification of the order in which the sequence elements should be performed and implicit acquisition of spatial accuracy for each element. Here we investigated the time course of le

11. Transfer of Dynamic Learning Across Postures
When learning a difficult motor task, we often decompose the task so that the control of individual body segments is practiced in isolation. But on re-composition, the combined movements can result in novel and possibly complex internal forces between the body segments that were not experienced (or did not need to be compensated for) during isolated practice
