Uma marcha normal depende de um funcionamento adequado do sistema locomotor, em todos os seus níveis. Mediante a presença de uma marcha anormal, muitas vezes torna-se necessária a utilização de dispositivos auxiliadores, sendo a bengala o mais utilizado. Dentre as suas várias utilidades, encontra-se uma possível redução das pressões plantares em regiões específicas dps pés, durante a caminhada. Devido a escassez de estudos que envolvem a correlação entre as pressões plantares e as forças aplicadas na bengala durante a caminhada, o objetivo do presente estudo foi construir um protótipo capaz de mensurar as pressões plantares durante a marcha de sujeitos, com e sem a utilização de uma bengala em três alturas diferentes, ou seja, na altura preconizada, cinco centímetros acima desta e cinco centímetros abaixo. Trata-se de um estudo transversal analítico que foi constituído por 15 sujeitos hígidos. sendo 13(86,7%) do gênero... / Currently, the human walking is the most investigated pattern of locomotion. A normal gait depends on a proper functioning of the locomotor system at all levels. By the presence of an abnormal gait, often becomes necessary the use of assistive devices, being the cane the most utilized. Among its many uses, it is found a possible reduction of plantar pressures in specific regions of the foot during walking. Due to the lack of studies involving the correlation between plantar pressures and forces appplied to the cane during the walk, the aim of this study was to build a prototype able to measure plantar pressures during the gait of individuals, with and without the use of a cane at three different heights, at the recommended height, five centimeter above it and five centimeters below. It is a cross-sectional analysis consisted of 15 healthy individuals, being 13 (86,7%) females and 2 (13.3%) males. At first, they walked two times in a corridor of about five meter long, using a sensorized sandal in each foot ... (Complete abstract click electronic access below)

A new ultrasound intensity meter : characterization and optimization

Manning, Gavin N. January 1987 (has links)
The principle of operation of a novel rotating disk ultrasonic intensity meter is studied. Its characteristics are explained by a competition between acoustic radiation pressure and viscous drag on the disk. Acoustic streaming does not play a significant role in the operation of this meter as it is now configured. Experiments are described which were done to find the optimum dimensions and position for a nylon disk. In this optimum configuration, the rotation rate of the disk is related to the ultrasonic intensity by a power law. This relationship is theoretically predicted and found to hold as the ultrasonic intensity varies by a factor of at least ten. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
