Purpose: Little information is available on joint kinematic adaptations during walking on cross-slope surfaces (i.e. a surface incline perpendicular to the direction of locomotion). This study aimed to evaluate the effects of cross-slope surfaces on three-dimensional (3D) kinematics of hip, knee, and ankle joints during stance phase of walking.  Methods: This is a quasi-experimental study...

Background:Chronic synovitis is one of the most important complications in haemophilic patients. Rifampin is anantibiotic which its intra-articular injecion leads to destruction of the synovial membrane of haemophilic patientsmedically.Materials and Methods: Between September 2003 and November 2005, we administered intra-articular rifampinin ١۶ haemophilic joints of ٨ haemophilic patients.Resul...

in present paper, a point to point optimal path is planned for a mobile manipulator with flexible links and joints. for this purpose, a perfect dynamic modeling is performed for mobile manipulators considering large deformation in links, shear effects, elastic joints, effect of gravitation, and non-holonomic constraints. to study large deformation of links, non-linear relation of displacement-s...

Arthrogryposis as a congenital malformation that refers to the fixed flexion of one or more joints as a result of stiffness or limited movements of multiple joints, change of posture and limb function due to permanent contracture of joints and wasting of muscles that usually occur at early stage of gestation. This report describes congenital arthrogryposis associated with musculoskeletal defect...

Arch dams are generally built in cantilvever monoliths. Vertical contraction joints between monoliths control the stresses due to concrete shrinkage and temperature variations. Past studies in earthquake safety evaluation of the system often show the tensile fracture and local nonlinear deformation of joints. In this paper, some nonlinear joint element constitutive models are presented to exami...
