OBJECTIVE To determine the knowledge of Brazilian Orthopedic Surgeons on the costs of orthopedic surgical devices used in surgical implants . METHODS A questionnaire was applied to Brazilian Orthopedic Surgeons during the 46th Brazilian Congress on Orthopedics and Traumatology . RESULTS Two hundred and one Orthopedic Surgeons completely filled out the questionnaire. The difference between t...

background and aims. the aim of this study was to determine the stress patterns within an implant and the effect of different types of connections on load transfer. materials and methods. three different types of implant-abutment connections were selected for this study. sample a: 1.5-mm deep internal hex corresponding to a lead-in bevel; sample b: a tri-channel internal connection; and sample ...

Many texts of Biomechanics begin with a brief historical introduction. In it, a lot of people who influenced its development are mentioned. According what Humphrey and Delange expressed in a very good book on Biomechanics, "it is not possible to identify a true father of biomechanics” [1]. Contrary to this position, we consider that it is possible to give this distinction to the Austrian physic...

Background. The importance of using statistical approaches has increased and became necessary for researchers and specialists in sports biomechanics because they need more objective and accurate methods to increase knowledge. Objectives. Evaluate the reality of using practical significance in the articles published in scientific conferences in the biomechanical sport. Methods. One hundred twe...

A 2D biomechanical model of the tongue is used to simulate movement sequences and speech signals in Vowel-to-Vowel transitions. The analysis is focused on how central commands and biomechanics can interact and influence the physical speech signals. In particular, it is shown how complex velocity profiles can be explained by the biomechanics, and how the low-pass filtering effect of the biomecha...

Objectives—To investigate the eVect of bracing and taping on selected electromyographic, kinematic, and kinetic variables when landing from a jump. Methods—Fifteen netball players performed a jump, so as to land on their dominant limb on a force plate. Electromyographic activity was recorded from the gastrocnemius, tibialis anterior, and peroneus longus muscles. Subjects were also filmed and me...

Background Adolescent idiopathic scoliosis (AIS) can affect spine mobility and gait mechanisms. In some of the related science research it is showed that the kinematic differences in the spine, pelvis and lower limb may contribute to the causation and progression of idiopathic scoliosis. Various treatment methods have being used for scoliosis, however using brace is a commonly used method in th...
