1. SACROPELVIC FIXATION USING ILIAC SCREWS: EVALUATION OF TECHNIQUE AND COMPLICATIONS
RESUMO A fixação sacropélvica surgiu como uma necessidade de proteção à instrumentação sacral em construções longas, devido as falhas na interface implante- osso, e ao tratamento de doenças, nas quais não há possibilidades de fixação sacral, como infecções e tumores. Devido às dificuldades anatômicas e à complexa biomecânica espino-pélv

2. Study of muscle fatigue in isokinetic exercise with estimated conduction velocity and traditional electromyographic indicators
INTRODUCTION: In the study of human biomechanics, it is often desirable to evaluate fatigue in the muscles that are involved in performing a particular task. Identifying the phenomena responsible for this condition is a problem that in most cases is complex and requires appropriate research mechanisms. Isokinetic dynamometry (ID) and surface electromyography

3. Stresses distributions of screws of the vertebral fixation systems submitted to pullout strength using plane transmission photoelasticity. / Distribuição de tensões de parafusos do sistema de fixação vertebral submetidos a arrancamento utilizando fotoelasticidade de transmissão plana
The treatment of spinal deformities, degenerative disease, injuries and tumors on the vertebral column often demand the accomplishment of the internal fixation. The pedicular screws arising enabled the accomplishment of column segmental instrumentation more stable and became a standard procedure in accomplishing surgeries of correction, deformities stabiliza

4. DESENVOLVIMENTO DE UM SISTEMA DE PEDAIS DINAMOMÉTRICOS PARA AVALIAÇÃO BIOMECÂNICA NO CICLISMO / DEVELOPMENT OF A DYNAMOMMETER PEDALS SYSTEM FOR CYCLING BIOMECHANICS EVALUATION
The assessment of pedal forces is one of the more sophisticated methods applied on the sports sciences to accomplish cycling performance tests. With information of pedal forces the pedaling technique is evaluated based on the ability of the cyclists to produce and apply forces on the pedals. Several variables concerning the performance can be monitored with

5. Images acquisition system development and validation for sailing / Desenvolvimento e validação de sistema de aquisição de imagens na vela
This study aimed to develop instrumentation for images acquisition that makes possible movements quantification and kinematics analysis of the sailors hiking positions in Laser boats. Two waterproof boxes were developed for cameras protection, confectioned with fiberglass and acrylic lens viewfinder. The camera and lens viewfinder components had been tested

6. Identification of myofascial trigger points by computerized thermography / Termografia computadorizada na identificação de trigger points miofasciais
Computerized thermography, system with ability to capture the infrared light emissivity of any reflexive surface, is part of the current arsenal of instrumentation in biomechanics. Using this methodology, it is possible to evaluate the physiology of thermical maintenance through its skin surface representation. The aim of this work is to evaluate the thermog

7. Evaluation of the hip muscles mechanical behavior in transfemoral amputees / Avaliação do comportamento mecânico dos músculos do quadril em amputados transfemorais
Introduction Amputation at the transfemoral level leads to anatomical and functional adaptations that change the gate pattern and influences daily-life activities. It is well known that the side of the amputation presents lower force. However, it is not known if there is a specific angular position or angular velocity in that the force is even lower. Moreove

8. Analise das alterações nos padrões de preensão palmar em pianistas
This work describes an experimental study that aimed to quantitatively analyze the palmer gripping patterns of pianists during the execution of function tasks relating to gripping and speed of execution. Twenty-five subjects (11 pianists and 14 non-pianists) carried out 4 tasks with their right hand: Gross gripping at fast speed (T1); Gross gripping at low s
