OBJECTIVE The proliferation of studies using motivational signs to promote stair use continues unabated, with their oft-cited potential for increasing population-level physical activity participation. This study examined all stair use promotional signage studies since 1980, calculating pre-estimates and post-estimates of stair use. The aim of this project was to conduct a sequential meta-analys...

A novel automatic escalator was designed, constructed and used in the present investigation. The aim of the present investigation was to compare the effect of two repeated sessions of stair descending versus stair ascending exercise on muscle performance and health-related parameters in young healthy men. Twenty males participated and were randomly divided into two equal-sized groups: a stair d...

A stacked type stair-case patch antenna with dielectric substrate (εr= 2.33) has been conceived and is theoretically demonstrated. Unlike conventional microstrip antenna it shows remarkable improvement in bandwidth (around 20%) as well as gain (around 10.5 dBi). The proposed structure is designed with two identical stair-case patches. Thorough investigations of the proposed antenna along with t...

INTRODUCTION Arthrodesis of the ankle is an established operation. The lack of normal ankle movement after ankle arthrodesis reduced the ability of the patients to walk smoothly on the arthrodesis foot. It would have a more profound effect in negotiating stairs, because large ranges of dorsiflexion and plantarflexion are required to accomplish this activity. Although gait characteristics have b...

OBJECTIVES To demonstrate the usefulness of computer simulation techniques in the investigation of pediatric stair falls. Since stair falls are a common falsely reported injury scenario in child abuse, our specific aim was to investigate the influence of stair characteristics on injury biomechanics of pediatric stair falls by using a computer simulation model. Our long-term goal is to use knowl...

Temporal Activation of Core Muscles and Vasti in Isolated Patellofemoral Osteoarthritis during Stair-Stepping: A Case-Control Study

Unintentional injury due to falls is one of the main reasons for hospitalization among children 0-4 years of age. The goal of this study was to assess the psychosocial correlates of parental safety behaviours to prevent falls from a staircase due to the lack of or the lack of adequate use of a stair gate. Data were collected from a cross-sectional survey using self-administered questionnaires m...

Stair nesting allows us to work with fewer observations than the most usual form of nesting, the balanced nesting. In the case of stair nesting the amount of information for the different factors is more evenly distributed. This new design leads to greater economy, because we can work with fewer observations. In this work we present the algebraic structure of the cross of balanced nested and st...

Experts have advocated exercise with little success, and have turned to encouraging physical activity by incorporating it into daily activities such as taking the stairs over elevators. Much literature exists suggesting that environmental prompts can encourage the use of stairs and literature has established that some messages may be more effective than others. This study aimed to assess the ef...

This study aimed to compare gait properties during level walking and during stair ascent and descent with varying loads. Fifteen healthy young men (mean age: 22.1 ± 1.6 years) walked while holding four different loads relative to each subject’s body mass (0, 20, 40 and 60% of body mass: BM) on their backs. Stance time, swing time, and double support times were selected as gait parameters. All p...
