Worksites have been targeted as an important setting for physical activity interventions. A recent emphasis for health promoters is the use of point-of-choice interventions to encourage stair climbing at work. The purpose of this paper is to explore three point-of-choice campaigns to increase stair climbing at work.

Ten focus groups and a rating task were conducted with 59 employees from a University and a University Hospital in the UK. Focus groups were structured around three messages and four prompts and sought to explore the motivational power of the resources, identify factors contributing to their effectiveness and provide recommendations to improve and optimize content. Benefits and barriers to stair climbing at work were also explored. Focus groups were recorded, transcribed and coded to identify key themes.

Intra-personal factors health, motivation, social norms and time management influence stair climbing at work. Critically, extra-personal factors associated with the worksite itself can also bias a traveler’s choice independently of any intervention. Results suggest that messages targeting heart health have the greatest impact on reported propensity to climb the stairs at work. Messages targeting rate of respiration for fitness, however, may have a negative effect given that most people want to avoid getting out of breath at work.

Qualitative research is essential for developing and refining the design detail of point-of-choice interventions and tailoring their components to address individuals’ needs in different settings but there is little evidence of this in practice.

The purpose of this paper is to describe a compact wheelchair, which has two 3-degrees of freedom (DOF) legs and a 1-DOF base (the total DOF of the leg system is 7) for stair-climbing, and wheels for flat surface driving.

The proposed wheelchair climbs stairs using the two 3-DOF legs with boomerang-shaped feet. The leg mechanisms are folded into the compact wheelchair body when the wheelchair moves over flat surfaces. The authors also propose a simple estimation method of stair shape using laser distance sensors, and a dual motor driving system to increase joint power.

The proposed wheelchair can climb arbitrary height and width stairs by itself, even when they are slightly curved. During climbing, the trajectory of the seat position is linear to guarantee the comfort of rider, and the wheelchair always keeps a stable condition to ensure the stability in an emergency stop.

The wheelchair mechanism with foldable legs and driving wheels enables smooth stair climbing, efficient flat surface driving and additional useful motions such as standing and tilting.

The purpose of this paper is to present the mechanical design and stability analysis of a new stair‐climbing robotic wheelchair.

A prototype stair‐climbing robotic wheelchair is constructed comprising a pair of rotational multi‐limbed structures pivotally mounted on opposite sides of a support base. The short arm, long arm, and triangular support structures within each rotational multi‐limbed structure rotate under the actuating effects of epicyclical gear trains.

The robotic wheelchair ascends and descends stairs in a statically stable manner and has an efficient planar navigation capability.

In its current state of development, the robotic wheelchair is controlled and powered remotely via umbilical cords rather than an onboard processor and power supply.

The robotic wheelchair provides an effective solution for enhancing the mobility of the elderly and disabled.

The rotational multi‐limbed mechanisms are developed to ensure the stability of the sitting base at all stages of the stair navigation maneuver without the need for additional servo‐mechanism. The proposed robotic wheelchair shows the simplification of the associated operation process.

This paper aims to deal with the development of a novel lower limb exoskeleton to assist disabled people in stair ascending.

For this purpose, a novel design of a mixture of motors and cables has been proposed for users to wear them easily and show the application of the system in stair climbing.

One of the prominences of this study is the provided robot design where four joints are actuated with only two motors; each motor actuates either the knees or ankles. Another advantage of the designed system is that with motors placed in a backpack, the knee braces can be worn under clothes to be concealed. Finally, the system performance is evaluated using electromyography (EMG) signals showing 28 per cent reduction in energy consumption of related muscles.

This investigation deals with the development of a novel lower limb exoskeleton to assist disabled people in stair ascending.

The purpose of this research is to evaluate the impact of theory‐based poster messages on stair‐climbing behaviour in a work environment. The highest‐rated poster developed by the Public Health Agency of Canada's stairway to health program was used as a comparison condition.

Naturalistic observation of stair traffic was conducted in order to measure the effectiveness of poster prompts on stair‐climbing behaviour. Over a period of three years, three separate studies were conducted aimed at increasing stair‐use via experimentally manipulated and theory‐based poster messages.

Results suggest that messages derived from a norm‐based framework are more persuasive than generic information‐based posters when attempting to increase stair‐climbing behaviour.

Small increases in health‐related behaviours at work have important consequences for both individuals and organizations. Using poster messages derived from social psychological theory could prove advantageous for practitioners attempting to increase healthy behaviours at work.

This research provides the first evidence for the use of norm‐based health‐related messages targeted at increasing healthy behaviours. The study makes a theoretical contribution to the creation and application of norm‐based appeals using both simple and complex message framing. Prior to this study, there was no available research on the effectiveness of such appeals on health‐related behaviour.

The purpose of this paper is to describe an innovative compliance control architecture for hybrid multi‐legged robots. The approach was verified on the hybrid legged‐wheeled robot ASGUARD, which was inspired by quadruped animals. The adaptive compliance controller allows the system to cope with a variety of stairs, very rough terrain, and is also able to move with high velocity on flat ground without changing the control parameters.

The paper shows how this adaptivity results in a versatile controller for hybrid legged‐wheeled robots. For the locomotion control we use an adaptive model of motion pattern generators. The control approach takes into account the proprioceptive information of the torques, which are applied on the legs. The controller itself is embedded on a FPGA‐based, custom designed motor control board. An additional proprioceptive inclination feedback is used to make the same controller more robust in terms of stair‐climbing capabilities.

The robot is well suited for disaster mitigation as well as for urban search and rescue missions, where it is often necessary to place sensors or cameras into dangerous or inaccessible areas to get a better situation awareness for the rescue personnel, before they enter a possibly dangerous area. A rugged, waterproof and dust‐proof corpus and the ability to swim are additional features of the robot.

Contrary to existing approaches, a pre‐defined walking pattern for stair‐climbing was not used, but an adaptive approach based only on internal sensor information. In contrast to many other walking pattern based robots, the direct proprioceptive feedback was used in order to modify the internal control loop, thus adapting the compliance of each leg on‐line.

This paper aims to present a new stair‐climbing wheelchair that tries to solve adaptability problems of previous prototypes.

A new prototype has been built using a new strategy. The climbing process is splint into two subproblems: climbing a single step and positioning the wheels on the staircase.

An optimized solution has been found for each subproblem, due to this the presented prototype is able to climb any staircase built according to standards, has a high capacity load and its stable equilibrium is always guaranteed.

The presented prototype is able to climb a parallel staircase; future works will try to solve the non parallel staircase climbing problem.

The practical application is to build an industrial new model of wheelchair that allows handicapped people to increase their mobility.

The principal value of the paper consists in using two independent mechanical solutions to solve the subproblems that appear when the stair‐climbing problem is split.

The Durable Reconnaissance and Observation Platform (DROP) is a prototype robotic platform with the ability to climb vertical cinder block surfaces at a rate of 25 cm/s, make rapid horizontal to vertical transitions, carry an audio/visual reconnaissance payload, and survive impacts from 3 meters.

The platform uses a two‐wheel, two‐motor design that delivers high mobility with low complexity. DROP extends microspine climbing technology from a linear to rotary implementation, providing improved transition ability, increased speeds, and simpler body mechanics while maintaining microspine's ability to opportunistically grip rough surfaces.

The DROP prototype was able to climb rough, vertical walls at a speed of 25 cm/s. These wheels were also deployed on a commercial platform, the ReconRobotics Scout, and demonstrated additional mobility capabilities such as curb mounting and stair climbing.

This robot is the first wheeled robot to use microspine technology. Various aspects of the prototype robot's design and performance are discussed, including the climbing mechanism, body design, and impact survival.

Increasing physical activity (PA) is an international public health priority. This study aims to assess the impact of an environmental stair‐use intervention using “point of decision” prompts with varying messages in an NHS workplace in the UK.

Observational data were collected using a covert method (infra‐red sensors) in an interrupted time‐series design over an eight‐week period. Intervention consisted of posters displaying encouraging messages in the entrance to two stairways of an acute NHS hospital. The hospital site is a public building accessible to patients, staff (n=∼7,000), students and the general public. Questionnaires (n=221) assessed employee self‐reports of and attitudes towards stair‐use.

Following 24‐hour observational counts (n=143,514) no statistically significant differences were seen in either stair climbing or descent on either stairway through the introduction and removal of promotional posters. A number of determinants and barriers to stair‐use were identified. Posters were reported as “seen” by a low proportion of respondents (7‐25 per cent) and only a small number felt encouraged to use the stairs as a result of the prompts (25‐37 per cent of those who “saw” them, 3‐18 per cent of total sample).

The study evaluates the impact of a stair‐use intervention in a public hospital building, a setting within which research investigations have to date been limited. More research is needed to further investigate determinants and barriers to stair‐use and the impact of different message types and locations of “point‐of‐decision” prompts in a hospital setting.

Environmental interventions to increase stair‐use in this setting may be best placed within a comprehensive workplace programme including health education and multi‐component interventions.

“Point of decision” prompts are inexpensive as a long‐term intervention. As part of a large‐scale workplace health campaign, encouraging even a small percentage of employees to use the stairs in organisations of this size is of significance to workplace health promoters.
