Purpose. Although stair use in workplaces can provide an accessible means of integrating physical activity into work routines, there is little information available on how building design influences stair use. Design. This cross-sectional study assessed the relationship between stair use and the design and location of stairs. Setting. Ten threeor four-story academic buildings on two university ...

This study evaluated the ability of three different messages to encourage stair climbing on the Barcelona underground. Two weeks of baseline were followed by three banner intervention periods with three different messages, each for a 2 week period. Follow-up data was gathered two weeks after removing the messages. Stair climbing increased overall [odds ratio (OR) = 1.45; 95% confidence interval...

Stair climbing can be a low-cost and relatively accessible way to add everyday physical activity, but many building stairwells are inaccessible or unpleasant and elevators are far more convenient. This study explores the use of and attitude toward stairs in an innovative office building where the main elevators for able-bodied users stop only at every third floor ("skip-stop" elevators). These ...

BACKGROUND Peak internal knee abduction moment is a common surrogate variable associated with medial compartment knee loading. Stair descent has been shown to yield a greater peak knee abduction moment compared to level-walking. Changes in step width (SW) may lead to changes in frontal plane lower extremity limb alignment in the frontal plane and alter peak knee abduction moment. The purpose of...

PURPOSE This study was designed to determine whether engagement in stair taking can be increased in a worksite setting through the provision of an employer-sponsored, behavior-based incentive system in which employees (members) accumulate points that can be redeemed for merchandise. METHODS/DESIGN ChipRewards implemented stair utilization in one employer as a part of a larger health incentive...

In this paper, we present an algorithm for autonomous stair climbing with a tracked vehicle. The proposed method achieves robust performance under real-world conditions, without assuming prior knowledge of the stair geometry, the dynamics of the vehicle’s interaction with the stair surface, or lighting conditions. Our approach relies on fast and accurate estimation of the robot’s heading and it...

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...

Balanced nesting is the most usual form of nesting and originates, when used singly or with crossing of such sub-models, orthogonal models. In balanced nesting we are forced to divide repeatedly the plots and we have few degrees of freedom for the first levels. If we apply stair nesting we will have plots all of the same size rendering the designs easier to apply. The stair nested designs are a...
