Hamstring strains are common injuries, the majority of which occur whilst sprinting. An understanding of the biomechanical circumstances that cause the hamstrings to fail during sprinting is required to improve rehabilitation specificity. The aim of this study was to therefore investigate the biomechanics of an acute hamstring strain. Bilateral kinematic and ground reaction force data were capt...

This paper presents the use of multiple sensors for walking assessment and provision of cognitive feedback during early re-education of incomplete spinal cord injured (SCI) humans. The paper is focused on the swing phase estimation as an important part of the Functional Electrical Stimulation (FES) gait re-education system for incomplete spinal cord injured persons. The proposed sensory system ...

Background:Despite some successful dynamic simulation of self-impact double pendulum (SIDP)-as humanoid robots legs or arms- studies, there is limited information available about the control of one leg locomotion.Objective :The main goal of this research is to improve the reliability of the mammalians leg locomotion and building more elaborated models close to the natural movements, by modelin...

26 Human walking must be flexible enough to accommodate many contexts and goals. One 27 form of this flexibility is locomotor adaptation: a practice-dependent alteration to walking 28 occurring in response to some novel perturbing stimulus. Although studies have 29 examined locomotor adaptation and its storage by the central nervous system (CNS) in 30 humans, it remains unclear whether altered ...

It is known that humans intentionally choose skipping in special situations, e.g. when descending stairs or when moving in environments with lower gravity than on Earth. Although those situations involve uneven locomotion, the dynamics of human skipping on uneven ground have not yet been addressed. To find the reasons that may motivate this gait, we combined experimental data on humans with num...

Humans can make smooth, continuous transitions in walking direction from forward to backward. Thus, the processing of sensory input must allow a similar continuum of possibilities. Hip extension and reduced load are two important conditions that control the transition from the stance to swing phase during forward stepping in human infants. The purpose of this study was to determine whether the ...

In this study, we intend to show the basis of a general legged locomotion controller with the ability to integrate both posture and rhythmic motion controls and shift continuously from one control method to the other according to the walking speed. The rhythmic motion of each leg in the sagittal plane is generated by a single leg controller which controls the swing-to-stance and stance-toswing ...
