Objective: Unstable shoes have been recommended to osteoarthritis patients in order to reduce walking injuries. The aim of this study was to test the effect of unstable shoe on biomechanical selected variables related to injury during stanse phase of running. Materials & Methods: Twenty five healthy young male students available men (21±2.27years) participated in this study. Subjects were as...
The commercial finite element program LS-DYNA was employed to evaluate the response and energy absorbing capacity of cylindrical metal tubes that are externally wrapped with composite. The effects of composite wall thickness, loading conditions and fiber ply orientation were examined. The results demonstrate that a wrapped composite can be utilized effectively to enhance the crushing characteri...
This paper numerically investigates the seismic response of the filled joint under high amplitude stress waves using the combined finite-discrete element method (FDEM). A thin layer of independent polygonal particles are used to simulate the joint fillings. Each particle is meshed using the Delaunay triangulation scheme and can be crushed when the load exceeds its strength. The propagation of t...
Objective: The aim of this study was comparing the ground reaction forces, center of pressure and body center of mass changes in voluntary, semi-voluntary and involuntary gait termination in healthy young men. Methods: In this study, 12 young men performed termination of gait in three different patterns. The variable of peak antero-posterior and vertical forces in two directions at both limb...
Background: Forward head posture is one of the most prevalent abnormal postures in patients with neck disorders. The aim of this study was to evaluate the effects of forward head posture on gait ground reaction force characteristics in children. Methods: Twelve children with forward head posture (age: 11.8±1.3 years) and sixteen healthy control children (...
Background: The aim of this study was to compare the effect of standard (Adidas) and local (Nahrein) shoes on some biomechanical variables related to tibia stress fracture in healthy male recreational runners. Methods: Fifteen healthy men (mean age: 35±2.27 years, height: 180.93±5.39cm, and weight: 85.30±8.84kg) performed running with controlled velocity on ...
Introduction: The aim of this study was to evaluate the effect of unstable shoes on lower limb kinetic parameters of walking in healthy male students with different geometric shapes. Today, various shoes have been developed to reduce the effects of injury parameters and improve performance parameters for walking. Methods: 20 of the healthy male lambs were selected 178.96 ± 3.92 cm, 27 ± 3 y...
This paper presents a user-friendly rapid prediction tool of damage to struck and striking vessels in a ship collision event. To do this, the so-called upper bound theorem is applied to calculate internal forces and energies of any substructure involved in the ships crushing process. At each increment of indentation, the total crushing force is transmitted to the external dynamics MCOL program,...
