objectives: hypertonicity is a major problem in children with cerebral palsy that has not been explained effectively to address clinical decision making. therefore, this article aims to provide a theoretical framework about hypertonicity for clinicians, rehabilitation and medical practitioners to be used in their practice. methods: literature was reviewed to examine the new perspectives towards...

Head-up tilt (HUT) induces a reduction in preload, which is thought to be restored through sympathetic venoconstriction, reducing unstressed volume (V(u)) and venous compliance (VeC). In this study, we assessed venous inflow and outflow responses and their reproducibility and determined the relation with autonomic function during HUT. Eight healthy non-pregnant women were subjected to 20 degree...

PURPOSE Atheromatic plaque progression is affected, among others phenomena, by biomechanical, biochemical, and physiological factors. In this paper, the authors introduce a novel framework able to provide both morphological (vessel radius, plaque thickness, and type) and biomechanical (wall shear stress and Von Mises stress) indices of coronary arteries. METHODS First, the approach reconstruc...

Rev Esp Cardiol. 2005;58(2):121-5 121 It is well known that cardiovascular function is characterized by, among other factors, a number of biomechanical indices and parameters, and in turn, depends upon the phenomena that they describe. The article by Bia et al1 published in this issue of REVISTA ESPAÑOLA DE CARDIOLOGÍA assesses these parameters using in vitro techniques, and concludes that they...

controversy exists regarding cavity preparation for restoration of interproximal caries in posterior teeth in terms of preserving the tooth structure and suitable stress distribution. this study aimed to assess the effect of extension and type of class ii cavities and the remaining tooth structure in maxillary premolars restored with composite resin on the biomechanical properties of teeth usin...

What are the biomechanical implications in dynamics and evolution of a growing solid tumor? Although analysis some biochemical aspects related to signaling pathways involved spread tumors has advanced notably recent times, their feedback with mechanical is crucial challenge for global understanding problem. The aim this paper try illustrate role interaction between evolutionary processes (growt...

Scientific studies have been conducted to quantify attributes that may be important in the creation of more functional and comfortable lower-limb prostheses. The prosthesis socket, a human-machine interface, has to be designed properly to achieve satisfactory load transmission, stability, and efficient control for mobility. The biomechanical understanding of the interaction between prosthetic s...
