Understanding the biomechanical properties and the effect of biomechanical force on epithelial cells is key to understanding how epithelial cells form uniquely shaped structures in two or three-dimensional space. Nevertheless, with the limitations and challenges posed by biological experiments at this scale, it becomes advantageous to use mathematical and 'in silico' (computational) models as a...

Introduction: Upper limbs are more susceptible to musculoskeletal disorders. The OCRA method is suggested to measure the biomechanical risk of the associated with the manual, repetitive work in upper limbs. Questionnaires can be used to measure the symptoms of diseases and disabilities. The DASH questionnaire is one of these questionnaires that are used to evaluate disability of upper limbs. In...

: 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...
