Background: Vision plays an important role in supporting efficient locomotion. The present study aimed to measure the physiological cost index (PCI) and some kinematic parameters of preferred walking and jogging in blind and sighted students.Methods: A cross-sectional study was conducted among blind (n=18) and sighted (n=27) students aged 8-16 years. The following parameters were measured...

in this paper, stability analysis of walking gaits and robustness analysis are developed for a five-link and four-actuator biped robot. stability conditions are derived by studying unactuated dynamics and using the poincarã© map associated with periodic walking gaits. a stable gait is designed by an optimization process satisfying physical constraints and stability conditions. also, considering...

This paper presents the ability of hybrid zero dynamics (HZD) feedback control method to reproduce human like movements for walking push recovery of an under-actuated 3D biped model. The balance recovery controller is implemented on a three-dimensional under-actuated bipedal model subjected to a push disturbance. The biped robot model is considered as a hybrid system with eight degrees of freed...

introduction: many of study show decrease of quality of life in mothers of children with cerebral palsy due to care activity of their child but the researchers less pay attention to the decrease of mother’s quality of life in relationship with child-related factors like walking ability in children with cerebral palsy, so the aim of this study was tocomparing the quality of life of mothers with ...
