Climbing stairs is an incidental physical activity that people can incorporate within daily life. Observational studies have shown that posters at the point of choice between stairs and escalators can increase stair use. As the greatest public health benefits can be gained from encouraging the least active to exercise more, stair and escalator users were interviewed to assess whether poster pro...

BACKGROUND Transtibial amputees encounter stairs and steps during their daily activities. The excessive pressure between residual limb/socket may reduce the walking capability of transtibial prosthetic users during ascent and descent on stairs. The purposes of the research were to evaluate the interface pressure between Dermo (shuttle lock) and Seal-In X5 (prosthetic valve) interface systems du...

The purpose of this study was to describe an imaging based, subject specific model that was developed to quantify patellofemoral joint reaction forces (PFJRF's). The secondary purpose was to test the model in a group of healthy individuals while performing various functional tasks. Twenty healthy subjects (10 males, 10 females) were recruited. All participants underwent two phases of data colle...

The purpose of this study is Comparing Effect of a Period of Stair Exercise on Physical and Mental Fitness Factors of Active and Inactive Women. In this way 15 active women with average (age of 32.12+-6.74, height of 162.07+8.67 and weigh of 61.21+-5.34) and 15 inactive women with average (age of 33.62+-6.93, height of 161.25+-7.15 and weight of 64.32+-6.86) participated voluntarily. The testes...

BACKGROUND Understanding the biomechanics of the medial longitudinal arch (MLA) may provide insights into injury risk and prevention, as well as function of the arch-supporting structures. Our understanding of MLA deformation is currently limited to sit-to-stand, walking, and running. MATERIAL AND METHODS Three-dimensional deformation of the MLA of the right foot was characterized in 17 healt...

BACKGROUND Previous Stroke Therapy Academic Industry Roundtable (STAIR) meetings focused on preclinical evidence of drug efficacy and enhancing acute stroke trial design and performance. A fourth (STAIR-IV) was held to discuss relevant issues related to acute stroke drug development and regulatory approval. SUMMARY OF REVIEW The STAIR-IV meeting had 3 main focus areas. The first topic was nov...

Stair gait is a useful activity for the assessment of knee function. The aim of this study was to determine whether knee joint kinematics and moments are affected by the choice of stair gait cycle (SGC) and the step used to measure ground reaction forces (GRFs). This was investigated through motion analysis of ten non-pathological subjects as they ascended and descended a four-step staircase. T...

INTRODUCTION K4b2 (COSMED Srl Italy) is a portable device that is considered valid and reliable for measuring oxygen uptake (VO2) and carbon dioxide production (VCO2) under laboratory conditions. OBJECTIVES Evaluate the test-retest reliability of K4b2 during walking, stair climbing and descending stairs under free living conditions. METHODS Twelve participants completed two self-selected co...

To encourage an increase in daily activity, researchers have tried a variety of health-related communications, but with mixed results. In the present research-using the stair escalator choice context-we examined predictions derived from the Heuristic Systematic Model (HSM), Self Determination Theory (SDT), and related theories. Specifically, we tested whether (as predicted by HSM) signs that en...
