BACKGROUND For single gait tasks, associations have been reported between gait speed and cognitive domains. However, few studies have evaluated if this association is altered in dual gait tasks given gait speed changes with complexity and nature of task. We evaluated relative contributions of specific elements of cognitive function (including sustained attention and processing speed) to dual ta...

[Purpose] This study sought to identify the gait aspects according to the FES stimulation position in stroke patients during gait training. [Subjects and Methods] To perform gait analysis, ten stroke patients were grouped based on 4 types of gait conditions: gait without FES stimulation (non-FES), gait with FES stimulation on the tibialis anterior (Ta), gait with FES stimulation on the tibialis...

conclusions based on the findings, in case a child suffers from calf pain or gait disturbances during influenza outbreak, the possibility of bacm should be considered before performing laboratory tests, radiological examinations, or other investigations. introduction identification of the etiology of limping and gait disturbances in children necessitates accurate physical examination and histor...

the aim of this work is to use self organizing map (som) for clustering of locomotion kinetic characteristics in normal and parkinson’s disease. the classification and analysis of the kinematic characteristics of human locomotion has been greatly increased by the use of artificial neural networks in recent years. the proposed methodology aims at overcoming the constraints of traditional analysi...

We developed a questionnaire to assess motor imagery (MI) of gait and administered it to 33 controls and 28 individuals with PD. Our goals were: 1) compare gait MI in individuals with and without PD, 2) determine whether walking performance relates to gait MI and 3) compare gait MI in individuals with PD with and without freezing of gait. Gait MI was not different between PD and controls. There...

Objectives: Fear of falling (FOF) is a common complication after stroke affecting gait and balance performance in individuals with a history of stroke. The current study aimed at determining the influence of the level of FOF on gait and balance performance after chronic stroke. Methods: A total of 76 persons with chronic stroke (including 41 women), who had no cognitive impairment and could wa...

this paper employs nonlinear disturbance observer (ndo) for robust trajectory-free nonlinear model predictive control (nmpc) of biped robots. the ndo is used to reject the additive disturbances caused by parameter uncertainties, unmodeled dynamics, joints friction, and external slow-varying forces acting on the biped robots. in contrary to the slow-varying disturbances, handling sudden pushing ...

this paper proposes a gait planning approach to reduce the required friction for a biped robot walking on various surfaces. to this end, a humanoid robot with 18 dof is considered to develop a dynamics model for studying various 3d manoeuvres. then, feasible trajectories are developed to alleviate the fluctuations on the upper body to resemble human-like walking. in order to generate feasible w...
