BACKGROUND Despite frequent use of pedometers in interventions targeting youth PA, there is no literature that addresses the prevalence and reasons for protocol nonadherence. METHODS Adherence behaviors of early adolescents (n = 43; Meanage = 12.3 ± 1.0) in an 8-week, faith-based intervention were monitored/recorded. Students provided reasons for various aspects of protocol breach, which were...

BACKGROUND Total knee arthroplasty is effective to regain quality of life. Standing up from and sitting down on a chair and stair stepping motion are important in daily living. We previously reported in vivo kinematics of this implant during a stepping exercise. The purpose of this analysis was to assess in vivo knee motion during standing up from and sitting down on a chair and determine the m...

Terrain geometry is, in general, nonsmooth, nonlinear, nonconvex, and, if perceived through a robot-centric visual unit, appears partially occluded and noisy. This article presents the complete control pipeline capable of handling aforementioned problems real-time. We formulate trajectory optimization problem that jointly optimizes over base pose footholds, subject to height map. To avoid conve...

Regional plantar pressures during stair walking may be injurious in at risk populations. However, limited data are available examining the reliability of plantar pressure data collected during stair walking. The aims of this study were three fold; to assess the reliability of the plantar pressure data recorded during stair walking, to assess the effects of level ground and stair walking on plan...

The purpose of this study was to examine the effects of two interventions, motivational signs and artwork, on stair use in a campus building. Methods: A longitudinal intervention study with no control group was designed to evaluate the effects of motivational signs and art murals on stair use in a six-story building. Sensors were installed in stairwells to monitor stair use. After a three week ...

Joint biomechanics during stair walking may contain important information on functional deficits in patients with orthopaedic conditions but depend on the stair dimension. The goal of this study was to compare knee kinematics and kinetics between patients with good outcome 2 years after total knee arthroplasty (TKA) and age-matched controls during stair ascent and descent at two different stair...

<b><i>Hintergrund:</i></b> Aktuelle Leitlinien empfehlen phasenbasierte Behandlungsansätze wie das Skills-Training zur Affektiven und Interpersonellen Regulation mit Narrativer Therapie (STAIR/NT) Behandlung der Posttraumatischen Belastungsstörung nach komplexer Traumatisierung. Bislang ist jedoch keine systematische Übersicht Wirksamkeit ersten Therapiephase STAIR von S...

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...
