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...

OBJECTIVE To determine the neuroprosthetic effect of a peroneal nerve stimulator on tasks of functional ambulation in multiple sclerosis (MS). DESIGN A single point-in-time assessment of functional ambulation tasks under the conditions of no device and peroneal nerve stimulator. SETTING Outpatient academic medical center. PARTICIPANTS Participants (N=11) with diagnosis of MS (>6mo), dorsi...

OBJECTIVE To measure the validity of safety behaviours, safety equipment use and hazards reported on a questionnaire by parents/carers with children aged under 5 years participating in a series of home safety case-control studies. METHODS The questionnaire measured safety behaviours, safety equipment use and hazards being used as exposures in five case-control studies. Responses to questions ...

We propose and investigate thermometry of a setup employing dual quantum dots with staircase ground state configuration. The stair-case configuration actuates thermally controlled inelastic tunnelling, which translates into temperature sensitive conductance, thereby inducing thermometry. performance the set-up is then analyzed master equation (QME) for such systems in sequential tunnelling regi...
