BACKGROUND This study tested the effectiveness of a stair use promotion strategy in visible and hidden stairwells during intervention and post intervention follow up. METHODS A quasi-experimental study design was used with a 1 week baseline, a 3 week intervention, and post intervention at 2 and 4 weeks in 4 university buildings in San Antonio, Texas with stairwells varying in visibility. Part...

BACKGROUND Although studies have demonstrated that stair prompts are associated with increased physical activity, many were conducted in low-rise buildings over a period of weeks and did not differentiate between stair climbing and descent. PURPOSE This study evaluated the impact of a prompt across different building types, and on stair climbing versus descent over several months. METHODS I...

Individuals with anterior cruciate ligament (ACL) reconstruction are at increased risk to develop knee osteoarthritis (OA). Gait analysis describing kinetics of the lower extremity during walking and stair use (stair ascent and stair descent) can provide insight to everyday dynamic knee joint loading. In this study, we compared lower extremity gait patterns of those with ACL reconstruction (>1 ...

This study aimed to evaluate whether a stair-promoting signed intervention could increase the use of the stairs over the elevator in a health-care facility. A time-series design was conducted over 12 weeks. Data were collected before, during and after displaying a signed intervention during weeks 4-5 and 8-9. Evaluation included anonymous counts recorded by an objective unobtrusive motion-sensi...

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...

BACKGROUND Natural foods contain not only nutrients, but also nonnutritious and potentially harmful chemicals. Thus, animals need to evaluate food content in order to make adequate feeding decisions. RESULTS Here, we investigate the effects of acids on the taste neuron responses and on taste behavior of desirable, nutritious sugars and sugar/bitter compound mixtures in Drosophila melanogaster...

Molecular data suggest that receptors for all bitter ligands are coexpressed in the same taste receptor cells (TRCs) while physiological results indicate that individual TRCs respond only to a subset of bitter stimuli. It is also unclear to what extent bitter-responsive neurons are stimulated by non-bitter stimuli. To explore these issues, single neuron responses were recorded from the rat nucl...

INTRODUCTION The challenging nature and high incidence of trips and falls in the elderly during stair negotiation has led to numerous research studies investigating lower extremity biomechanics in older adults [1]. Stair descent has been shown to yield greater impact peak ground reaction force (GRF), and greater peak knee internal abduction moment compared to stair ascent and level-walking [2,3...
