1. Differences in motor control of an aiming task in different group ages of the elderly
Abstract Aims: This study aimed to investigate how different age groups of older adults perform and control movements in a goal-directed aiming task and the importance of visual feedback during these movements. Methods: Participants included 22 old adults, divided in two age groups: younger (60-70 yr) and older (80-90 yr). Subjects performed the task in

2. Artificial motor control for electrically stimulated upper limbs of plegic or paretic people
Introduction: Functional Electrical Stimulation (FES) is a technique used in the restoration and generation of movements performed by subjects with neuromuscular disorders such as spinal cord injury (SCI). The purpose of this article is to outline the state of the art and perspectives of the use of FES in artificial motor control of the upper limbs in pareti

3. Static and dynamic postural control in low-vision and normal-vision adults
OBJECTIVE: This study aimed to evaluate the influence of reduced visual information on postural control by comparing low-vision and normal-vision adults in static and dynamic conditions. METHODS: Twenty-five low-vision subjects and twenty-five normal sighted adults were evaluated for static and dynamic balance using four protocols: 1) the Modified Clinica

4. Influências do rebaixamento do arco longitudinal medial e da bandagem plantar no controle postural / Influence of low plantar arch and foot taping on postural control
Esta dissertação parte da premissa de que o desalinhamento dos arcos plantares estão associados ao mal funcionamento do pé e a subseqüentes desequilíbrios mecânicos gerados por compensações na cadeia cinética e articulações adjacentes. A bandagem plantar é uma das técnicas comumente utilizadas no tratamento e prevenção de lesões decorrentes

5. Development and assessment of an upper limb hybrid system for quadriplegics / Desenvolvimento e avaliação de um protótipo de sistema híbrido para membro superior de tetraplégicos
Generally, individuals with motor impairments in the upper limbs have difficulties performing the movement of objects, which is essential for the execution of activities of daily living. Thus, these individuals do not perform these activities or perform them inefficiently. Toward satisfactory manipulation, reach and grasp movements of objects performed with

6. Avaliação do equilíbrio, da simetria corporal e da funcionalidade em pacientes hemiparéticos submetidos ao treino por biofeedback visual. / Evaluation of the balance, the corporal symmetry and the functionality in submitted hemiparéticos patients to the trainings for biofeedback visual.
O objetivo do estudo foi avaliar o equilíbrio, a simetria corporal e a funcionalidade após o treino de equilíbrio por biofeedback visual por meio do Wii Fit. Participaram do estudo vinte indivíduos hemiparéticos pós AVE com idade de 59,358,3 anos, sendo divididos aleatoriamente em dois grupos: o grupo convencional (GC) submetido à fisioterapia convenc

7. Perception and production of speech in a hearing impaired child during therapy / Percepção e produção de sons de fala em uma criança com deficiência auditiva em terapia fonoaudiológica
Introduction: Very few studies discuss speech development in hearing impaired children in the first years of life due to methodological difficulties and the number of variables involved. Acoustic inspection of articulatory adjustments and attempts to imitate a model made by the infant in different contexts can be a method to comprehend the manner in which fi

8. Role of the hypothalamic pituitary adrenal axis in the control of the response to stress and infection
The release of adrenocorticotropin (ACTH) from the corticotrophs is controlled principally by vasopressin and corticotropin-releasing hormone (CRH). Oxytocin may augment the release of ACTH under certain conditions, whereas atrial natriuretic peptide acts as a corticotropin release-inhibiting factor to inhibit ACTH release by direct action on the pituitary.

9. Social Context Rapidly Modulates the Influence of Auditory Feedback on Avian Vocal Motor Control
Sensory feedback is important for the learning and control of a variety of behaviors. Vocal motor production in songbirds is a powerful model system to study sensory influences on behavior because the learning, maintenance, and control of song are critically dependent on auditory feedback. Based on previous behavioral and neural experiments, it has been hypo

10. Inhibition of nitric oxide synthase does not alter ocular dominance shifts in kitten visual cortex.
1. Since nitric oxide has been proposed as a feedback factor in plasticity in the hippocampus, we tested whether it might also be a feedback factor in sensory-dependent plasticity in the cat visual cortex. 2. The effects of monocular deprivation were compared between eight hemispheres with infusion of a nitric oxide synthase inhibitor, and eight control hemi

11. Motor deficits in patients with large-fiber sensory neuropathy.
The issue of whether brain signals in the absence of peripheral feedback are sufficient to specify accurate movement was evaluated by studying motor performance in patients with loss of somesthetic afferent input as a result of acquired large-fiber sensory neuropathy. With visual guidance, movements and postures were impaired relatively little, but when visu

12. Somatosensory feedback modulates the respiratory motor program of crystallized birdsong
Birdsong, like human speech, involves rapid, repetitive, or episodic motor patterns requiring precise coordination between respiratory, vocal organ, and vocal tract muscles. The song units or syllables of most adult songbirds exhibit a high degree of acoustic stereotypy that persists for days or months after the elimination of auditory feedback by deafening.
