objectives: this paper describes further improvement and preliminarily evaluation of a novel viscoelastic ankle-foot prosthesis prototype. the objective was to control the ankle hysteresis at slow and normal walking speeds. methods: inspired by the ankle biomechanics, in which the hysteresis differs based on the gait speeds, a manually damping control mechanism imbedded in the prosthesis for ad...

Objectives: There exists no study concerning gait pattern while engaging in dual-task activities on different sizes of mobile devices. The present study aimed to compare gait patterns during normal walking, walking with smartphone use, and walking with tablet use.  Methods: Seventeen healthy female participants with an age range of 19-24 years (mean±SD age: 20.29±1.61 years, weight: 49.82±4.46...

Abstract. We apply Munthe-Kaas and Crouch-Grossman methods in the solution of some mechanical problems. These methods are quite new, and they exploit intrinsic properties of the manifolds de ned by the mechanical problems, thus ensuring that the numerical solution obey underlying constraints. A brief introduction to the methods are presented, and numerical simulations show some of the propertie...

Objectives: The purpose of this study was to evaluate the concurrent validity of the Farsi version of Functional Gait Assessment (FGA), Timed Up & Go (TUG), and Gait Speed tests in Persian communitydwelling older adults. Methods: Subjects were 100 males in falling or no falling history group (50 subjects in each group). Subjects were community-dwelling adults aged 60-90 years who were living...

Background. There have been many studies on partial weight support walking training. However, most studies have been performed in treadmill settings, not in actual walking environments. Objectives. This study aimed to investigate the effect of partial weight support ground walking training on the temporal and spatial gait parameters of chronic stroke patients. Methods. This study was designed...

With the increasing number of people who have problems with their walking, a new type of gait rehabilitation training robot has been put forward and designed. In order to meet the requirements of the gait rehabilitation training, the whole mechanical structure and control system have been designed, and the model machine for gait rehabilitation training robot has been made. Using the human gait ...

objectives: the purpose of this study was to compare spatio-temporal gait parameters between elderly and young male subjects. methods & materials: 57 able-bodied elderly (72±5.5 years) and 57 healthy young (25±8.5 years) subjects participated in this study. a four segment model consist of trunk, hip, shank, and foot with 10 reflective markers were used to define lower limbs. kinematic data coll...
