1. Control of a robotic knee exoskeleton for assistance and rehabilitation based on motion intention from sEMG
Introduction: This work presents the development of a novel robotic knee exoskeleton controlled by motion intention based on sEMG, which uses admittance control to assist people with reduced mobility and improve their locomotion. Clinical research remark that these devices working in constant interaction with the neuromuscular and skeletal human system impr

3. Reconstruction of gait biomechanical parameters using cyclograms and artificial neural networks
Abstract Introduction Historically, assessing the quality of human gait has been a difficult process. Advanced studies can be conducted using modern 3D systems. However, due to their high cost, usage of these 3D systems is still restricted to research environments. 2D systems offer simpler and more affordable solutions. Methods In this study, the gait of 4

4. Photogrammetry: a Non-Invasive and Objective Method for Detecting Locomotion Problems in Broiler Chickens
ABSTRACT Locomotion problems in broiler chickens can cause economic losses of up to 40% of the total revenues due to carcass condemnation and downgrading at processing. Leg disorders, such as femoral lesions, tibial dyschondroplasia, and spondylolisthesis, substantially impact the welfare of chickens as these disorders can prevent birds from reaching the fee

5. Origins of Bipedalism
ABSTRACT This article aimed to review various theories of bipedalism and provide a holistic answer to human evolution. There have been two questions regarding bipedalism: i) why were the earliest hominins partially bipedal?, and ii) why did hominins become increasingly bipedal over the time and replaced their less bipedal ancestors? To answer these questions

6. A model for selecting alternate foot placement during human locomotion
The selection of alternate foot placement is based on visual inputs and the prediction of future foot placement combined with a set of internal rules that are guided by three determinants: minimum foot displacement, stability, and maintenance of forward progression. These three determinants are weighted differently, depending on different constraints. The fi

7. Some aspects of chicken behavior and welfare
Brazil is the world leader in broiler production and export. It achieved this position mainly to its excellent supply chain structure and climate, which favor poultry and grain production throughout its territory. Although Brazilian egg production is not as important as broiler production, this segment presents great potential of increasing its share in the

8. Crianças que se percebem competentes e são intrinsecamente motivadas são motoramente mais competentes? um estudo associativo entre desenvolvimento motor e aspectos psicossociais de escolares
This research aimed to investigate the perception of competence, motivational orientation and motor performance in children from public schools. More specifically we sought: check if children who have motor difficulties in gross motor skills fundamental also present difficulties in motor tasks specific to fine motor skills and balance, as well as the differe

9. A simple method to assess freezing of gait in Parkinson's disease patients
Freezing of gait (FOG) can be assessed by clinical and instrumental methods. Clinical examination has the advantage of being available to most clinicians; however, it requires experience and may not reveal FOG even for cases confirmed by the medical history. Instrumental methods have an advantage in that they may be used for ambulatory monitoring. The aim of

10. Padrões de propulsão para cadeiras de rodas e seus fatores de desempenho / Standards of propulsion in wheelchair and its factors or performance
O objetivo deste trabalho é propor um mecanismo alternativo para a superação de barreiras arquitetônicas do tipo rampas de até 8°. As cadeiras de rodas manuais convencionais exigem esforço muscular do usuário nos aros de propulsão, sendo muitas vezes um mecanismo ineficiente na superação destas barreiras arquitetônicas. Este mecanismo alternativo

11. Estudo comparativo da densidade e topografia de neurônios de retinas de Philodryas olfesii e P. patagoniensis (serpentes, colubridae) / Text not informed by the author.
Snakes are a diversified group found in almost all regions of the planet, occupying different habitats, with exception to Polar Regions, a few islands and the deeper ocean waters. Its diversity indicates the high variability of sensory organs, which are adapted to the habits and habitats of each species. Studies about snakes visual system are scarce and have

12. Descrição anatômica dos músculos da mão do macaco prego (Cebus libidinosus, Rylands et al., 2000) e sua relação com a habilidade manual destes primatas
Cebus libidinosus is a species of primate with high cognitive capacity and great motor ability. These animals demonstrate high manual capacity of tools use during foraging and locomotion. The use of tools is considered basic in the evolutionary process of the humanity. The Cebus libidinosus is capable to hold objects as rocks and to use them as tool to open
