background: prevention of slipping accidents requires provision of adequate friction through the use of suitable combinations of footwear and underfoot surfaces. shoe sole tread groove is one of the important factors on friction coefficient during walking. objective: to measure the effect of different shoe sole tread groove depths and different surfaces on the required quotient of friction (q),...

The main problem of Pedestrian Dead-Reckoning (PDR) using only a body-attached IMU is the accumulation of heading errors. The heading provided by magnetometers in indoor buildings is in general not reliable and therefore it is commonly not used. Recently, a new method was proposed called Heuristic Drift Elimination (HDE) that minimizes the heading error when navigating in buildings. It assumes ...

We consider a Planar Face Complex (PFC). It is defined by the immersion of a planar and connected graph G, which comprises a set of vertices joined by curved edges. G decomposes the plane into faces that need not be manifold or open-regularized and may be bounded by a single loop edge. The PFC may, for example, be used to represent the complex street network of a city, the decomposition of a co...

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...

purpose :   obesity has been identified as a risk factor for the development of bulimia nervosa (bn) in those who try to lose weight.  the purpose of the present study was to examine the effect of walking exercise in order to provide a method for overcoming bulimia nervosa in obese young women suffering from bulimia nervosa . methods:   twenty obese women with bulimia nervosa (body mass index [...

background: osteoporosis is one of the most common metabolic bone diseases. the purpose of this study is to investigate the effect of a walking education program based on the health belief model (hbm) on osteoporosis among women.   material and methods in this quasi-experimental research design, 120 patients (60 experimental and 60 control),who were registered with the health centers in fasa ci...

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...
