Stair climbing is one of the most challenging tasks for vehicles, especially when transporting people and heavy loads. Although many solutions have been proposed demonstrated in practice, it necessary to further improve their ability safety. This paper presents a systematic review scientific engineering stair literature, providing brief descriptions mechanism method operation highlighting advan...

The purpose of this study is to investigate the kinematics in humans during stair climbing and the influence of stair slope variation on gait cycle .The analysis of biomechanical aspect involved in stair ascent and descent can add to our understanding of the diverse and complicated processes involved in human locomotion and also be useful in the design of private and public environments where s...

The aim of the study was to investigate differences in frontal plane knee kinetics, onset timing and duration of the gluteus medius (GMed), adductor longus (AL), and vastus medialis oblique (VMO) during stair ambulation between those with and without patellofemoral pain syndrome (PFPS). Twenty PFPS patients and twenty healthy participants completed stair ambulation while surface electromyograph...

Background Early detection of movement deficits during step initiation will facilitate the selection of the optimal physiotherapy management strategy. The main aim of the study was to assess potential differences in step initiation between 5- and 6-year-old children with faulty posture who had been diagnosed with neurodevelopmental disorders during infancy and healthy children. Methods The ex...

The purpose of this study was to examine the effects of load carrying methods, stair slopes and walking speeds on heart rate and walking postures. Nine participants climbed up and down stairs with various stair slopes (24°, 30° and 36°), walking speeds (72, 96, and 132 steps per minute), and using different load carrying methods (empty loads, backpack, and hand-held). The effects of these facto...

This paper presents the design of a quadrupedal robot that can automatically adapt its gait to, and climb, staircases of different configurations. This is accomplished by endowing the robot with a parameterized gait for stair climbing: First, a gait plan is synthesized that allows the robot to climb a stair of known dimensions. Second, the robot approaches a previously unseen stair and perceive...

OBJECTIVE We performed a literature review with the main aims to propose an updated overview of the effectiveness of stair-use interventions and to determine the most effective type of intervention. METHODS We systematically searched stair-use interventions performed in worksites or public settings, published up to mid 2013. We used a harvest plot approach to visualize the findings in additio...

BACKGROUND Preoperative evaluation of lung resection candidates with impaired pulmonary reserves includes measurement of aerobic capacity. Stair climbing is an attractive low-cost alternative to treadmill exercise testing but it lacks standardisation. OBJECTIVES To directly compare stair climbing and treadmill exercise testing with respect to an established cut-off value for lung resection. ...
