We analyzed kinematics of stair ascent and descent in autistic children and adolescents in comparison with age-matched healthy children and adolescents. Eight healthy adolescents, 6 autistic adolescents, 7 healthy children and 6 autistic children participated in the study. We found that autistic subjects of both groups showed significantly more fluctuations of hip joint angular velocity than ag...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
AIM To investigate risk and protective factors for stair falls in children aged <5 years. METHODS Multicentre case-control study at hospitals, minor injury units and general practices in and around four UK study centres. Cases were children with medically attended stair fall injuries. Controls were matched on age, sex, calendar time and study centre. A total of 610 cases and 2658 controls par...
Understanding joint kinetics during activities of daily living furthers our understanding of the factors involved in joint pathology and the effects of treatment. In this study, we examined hip and knee joint kinetics during stair climbing in 35 young healthy subjects using a subject-specific knee model to estimate bone-on-bone tibiofemoral and patello-femoral joint contact forces. The net knee...
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...
Fractures at the femoral neck play an important role in morbidity and mortality among older adults. Understanding the loading environment is a crucial factor for reducing the incidence of fracture at this site. In this study, the stresses on the femoral neck during stair ascent and descent were estimated. These femoral neck stresses were also compared to the peak loading from internal hip momen...
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...
