Differential Consequences of Unilateral Nasal Air-Puff Stimulation on Breathing Pattern and Respiratory System Mechanics in Tracheotomized Rats

The efficacy of diaphragmatic breathing practice on respiratory function, balance, and quality of life in elderly women

Introduction: Introduction: The respiratory system affects the motor control and stability of the body, especially in the elderly. The present study aimed to determine the effect of diaphragmatic breathing practice on respiratory function, balance, and quality of life in elderly women. Materials and Methods: Forty elderly women with a mean age of 72.40 years participated in this study voluntari...

Effect of Dynamic Neuromuscular Stabilization Breathing Exercises on Some Spirometry Indices of Sedentary Students With Poor Posture

Purpose: Dynamic Neuromuscular Stabilization (DNS) approach is developed based on neurodevelopmental kinesiology and reflex-mediated core stabilization concepts. But the outcomes of this approach remain unclear. So changes in some spirometry indices in response to DNS breathing exercises in sedentary students with poor posture will be explored. Methods: In this single-group pretest-posttest st...

Dynamic Fracture Analysis Using an Uncoupled Arbitrary Lagrangian Eulerian Finite Element Formulation

This paper deals with the implementation of an efficient Arbitrary Lagrangian Eulerian (ALE) formulation for the three dimensional finite element modeling of mode I self-similar dynamic fracture process. Contrary to the remeshing technique, the presented algorithm can continuously advance the crack with the one mesh topology. The uncoupled approach is employed to treat the equations. So, each t...

Optimal Determination of Respiratory Airflow Patterns Using a Nonlinear Multicompartment Model for a Lung Mechanics System

We develop optimal respiratory airflow patterns using a nonlinear multicompartment model for a lung mechanics system. Specifically, we use classical calculus of variations minimization techniques to derive an optimal airflow pattern for inspiratory and expiratory breathing cycles. The physiological interpretation of the optimality criteria used involves the minimization of work of breathing and...
