encouraging an active lifestyle is an essential part of successful rehabilitation programs, and the link between physical activity and quality of life (qol) is well established among patients with mobility disorders. biomechanical aspects of wheelchair design play an important role in physical activity and social participation of disabled individuals. this review focuses on key biomechanical fe...

: investigating the mechanical behaviour of a healthy human ankle shows that it can be simulated by a mechanism composed of simple elements such as spring, and actuator. hence, appropriate design of this mechanism can be resulted to an artificial ankle that can help amputees properly. researches show that whatever the biomechanical behaviour of artificial ankle is similar to that of natural ank...

STUDY DESIGN An Ilizarov-type apparatus was applied to the tails of rats to assess the influence of immobilization, chronically applied compression, and sham intervention on intervertebral discs of mature rats. OBJECTIVES To test the hypothesis that chronically applied compressive forces and immobilization cause changes in the biomechanical behavior and biochemical composition of rat tail int...

Introduction/Objective. Finite element analysis (FEA) is mathematical method which can be used for the assessment of biomechanical behavior dento-alveolar complex. The objectives were to analyze changes teeth and supporting tissues under occlusal load in cases horizontal vertical alveolar bone loss, assess potential impact tooth displacement altered stress distribution on further damage, evalua...

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...

Organ motion, especially respiratory motion, is a technical challenge to radiation therapy planning and dosimetry. This motion induces displacements and deformation of the organ tissues within the irradiated region which need to be taken into account when simulating dose distribution during treatment. Finite element modeling (FEM) can provide a great insight into the mechanical behavior of the ...

OBJECTIVE To determine the influence of neoplasia on the biomechanical properties of canine antebrachia. STUDY DESIGN Ex vivo biomechanical study. SAMPLE POPULATION Osteosarcoma (OSA)-affected canine antebrachia (n = 12) and unaffected canine antebrachia (n = 9). METHODS Antebrachia were compressed in axial loading until failure. A load-deformation curve was used to acquire the structural...

Tumor development progresses through a complex path of biomechanical changes leading first to cell growth and contraction and then cell deadhesion, scattering, and invasion. Tumorigenic factors may act specifically on one of these steps or have a wider spectrum of actions, leading to a variety of effects and thus sometimes to apparent contradictory outcomes. Here we used micropatterned lines of...
