Purpose: Considering the influence of horizontal velocity on many biomechanical characteristics of walking, the purpose of this study was to investigate how inter-lower-limbs local and global asymmetry is influenced by changes in walking speed from slow to fast. Methods: Ground reaction force data and trajectory of attached markers of bilateral lower limbs of 15 right leg-dominant able-bodied ...

this is retrospective double-blind research, which was carried out in imam khomeini hospital in order to study the accuracy of color doppler ultrasonography for detecting the site and grade of stenosis in cervical carotid artery. 40 patients with mean age of 62 years studied with color doppler before dsa angiography. the most common sites of stenosis were left internal carotid (39.5%) and right...

background: autoregulation of blood flow is a marvelous phenomenon balanc- ing blood supply and tissue demand. although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. the biomechanical aspect provides insights to us to model vessel diameter changes more precisely and comp...

A 3D biomechanical model of the tongue is presented here. Its goal is to evaluate the speech control model. This model was designed considering three constraints: speech movement speed, tongue movements and tongue soft tissue mechanical properties. A model of the tongue has thus been introduced taking into account the non linear biomechanical behavior of its soft tissues in a large deformation ...

Synopsis: Computational neuroethology is the use of modeling and simulation to study adaptive behavior. The conceptual framework of computational neuroethology emphasizes that nervous systems are embodied, that is, sensory pre-processing, biomechanical properties, and the integration of sensing and action during active perception are all critical for behavior. Furthermore, animals are situated ...

Understanding of tibiofemoral joint mechanics at multiple spatial scales is essential for developing effective preventive measures and treatments for both pathology and injury management. Currently, there is a distinct lack of specimen-specific biomechanical data at multiple spatial scales, e.g., joint, tissue, and cell scales. Comprehensive multiscale data may improve the understanding of the ...
