This study aimed to investigate the influence of prophylactic ankle taping on two balance tests (static and dynamic balance) and one jump test, in the push off and the landing phase. Fifteen active young subjects (age: 21.0 ± 4.4 years) without previous ankle injuries volunteered for the study. Each participant performed three tests in two different situations: with taping and without taping. T...

Background and Objectives: Knee joint, like other joints in the body, is affected by defects, injuries and diseases. Genu valgum is one of the most common lower limb complications. The purpose of the present study was to determine the effects of corrective exercises using Thera-Band on components of ground reaction force in boy students with genu valgum during running. Materials and Methods: T...

In this study, a finite element model of a tissue-mimicking, viscoelastic phantom with a stiffer cylindrical inclusion subjected to an acoustic radiation force (ARF) is presented, and the resulting shear waves through the heterogeneous media are simulated, analyzed, and compared with experimental data. Six different models for the ARF were considered and compared. Each study used the same finit...

The purpose of this study was to investigate the influence of real time verbal feedback to optimise push arc during over ground manual wheelchair propulsion. 10 healthy non wheelchair users pushed a manual wheelchair for a distance of 25 metres on level paving, initially with no feedback and then with real time verbal feedback aimed at controlling push arc within a range of 85 ̊-100 ̊. The real t...

This study examined the effect of seat position on handrim biomechanics. Thirteen experienced users propelled a wheelchair over a smooth level floor at a self-selected speed. Kinetic and temporal-distance data were collected with the use of an instrumented rim and a motion analysis system. A custom-designed axle was used to change the seat position. We used repeated measures analysis of varianc...

We have developed a novel and relatively simple method for magnifying forces perceived by an operator using a surgical tool. A sensor measures force between the tip of a tool and its handle, and a proportionally greater force is created by an actuator between the handle and a brace attached to the operator’s hand, providing an enhanced perception of forces at the tip of the tool. Magnifying for...

This qualitative study, applying in-depth interview and push-pull theory, analyzed the factors influencing Chinese students’ choices to attend international branch campuses (IBCs) in China. The results showed that pull can be found from admission policies, pedagogical characteristics, postgraduation issues, while push are caused by China’s higher education entrance examination. study also discu...

Push or Pull? Drivers of Female Labor Force Participation during India’s Economic Boom In the past twenty years, India’s economy has grown at increasing rates and now belongs to the fastest-growing economies in the world. This paper examines drivers of female labor force participation in urban India between 1987 and 2004, showing a much more nuanced picture of female labor force participation t...
