TL;DR: Two perturbed conditions were introduced in which stair distances were changed, forcing subjects to execute a foot-strike, either very far from or near to the stair, before climbing it, so as to reveal any significant adaptations the climber would undertake to avoid slips or falls.

TL;DR: Abnormal movement patterns on the surgical side increase demands on other joints and could lead to permanent joint damage and should be addressed during the early post-operative period through additional interventions in an attempt to normalize the differences and potentially improve long-term joint health throughout the lower extremity.

TL;DR: This study shows a successful stair-climbing intervention at the worksite and identifies the main barriers to adoption and implementation related to location and visibility of posters and process evaluation was useful in identifying these barriers and in finding appropriate solutions.
Abstract: Background Stair climbing helps to accumulate short bouts of physical activity throughout the day as a strategy for attaining recommended physical activity levels. There exists a need for effective long-term stair-climbing interventions that can be transferred to various worksite settings. The aims of this study were: 1) to evaluate short- and long-term effectiveness of a worksite stair-climbing intervention using an objective measurement of stair climbing and a controlled design; and 2) to perform a process evaluation of the intervention. Methods We performed a controlled before-and-after study. The study was conducted in two corporate buildings of the same company located in Paris (France), between September, 2013 and September, 2014. The status of either “intervention site” or “control site” was assigned by the investigators. Participants were on-site employees (intervention site: n = 783; control site: n = 545 at baseline). Two one-month intervention phases using signs (intervention phase 1) and enhancement of stairwell aesthetics (intervention phase 2) were performed. The main outcome was the change in stair climbing, measured with automatic counters and expressed in absolute counts/day/100 employees and percent change compared to baseline. Qualitative outcomes were used to describe the intervention process. Results Stair climbing significantly increased at the intervention site (+18.7 %) but decreased at the control site (-13.3 %) during the second intervention phase (difference between sites: +4.6 counts/day/100 employees, p < 0.001). After the intervention and over the long term, stair climbing returned to baseline levels at the intervention site, but a significant difference between sites was found (intervention site vs. control site: +2.9 counts/day/100 employees, p < 0.05). Some important facets of the intervention were implemented as intended but other aspects had to be adapted. The main difficulty reported by the company’s staff members lay in matching the internal communications rules with critical intervention criteria. The program was maintained at the setting level after the end of the study. Conclusions This study shows a successful stair-climbing intervention at the worksite. The main barriers to adoption and implementation were related to location and visibility of posters. Process evaluation was useful in identifying these barriers throughout the study, and in finding appropriate solutions.

TL;DR: The mobile base of PerMMA Gen II has two operating modes: “advanced driving mode’ on flat and uneven terrain, and “automatic climbing mode” during stair climbing, which are triggered either by local and dynamic conditions or by external commands from users.
Abstract: Background This paper describes the development of a mobile base for the Personal Mobility and Manipulation Appliance Generation II (PerMMA Gen II robotic wheelchair), an obstacle-climbing wheelchair able to move in structured and unstructured environments, and to climb over curbs as high as 8 inches. The mechanical, electrical, and software systems of the mobile base are presented in detail, and similar devices such as the iBOT mobility system, TopChair, and 6X6 Explorer are described. Findings The mobile base of PerMMA Gen II has two operating modes: “advanced driving mode” on flat and uneven terrain, and “automatic climbing mode” during stair climbing. The different operating modes are triggered either by local and dynamic conditions or by external commands from users. A step-climbing sequence, up to 0.2 m, is under development and to be evaluated via simulation. The mathematical model of the mobile base is introduced. A feedback and a feed-forward controller have been developed to maintain the posture...

TL;DR: A vision based algorithm used to guide the Unmanned Ground Vehicles (UGV) for autonomous stairways climbing and implement it on UGV successfully is presented and the results validate the algorithm.
Abstract: In the paper, we present a vision based algorithm used to guide the Unmanned Ground Vehicles (UGV) for autonomous stairways climbing and implement it on UGV successfully. The reliability of guiding UGV to climb stairs requires evaluating two offset parameters: the position of vehicle on stairs and the orientation angle to stairs. The intention of our algorithm is to estimate these two parameters through extracting the stair edges robustly. To achieve this goal, we apply the Gabor filter to eliminate the influence of the illumination and keep edges, and propose a fast method to remove small lines. Finally we link stair edges, and estimate the offset parameters used to steer the vehicle by RANSAC algorithm. Experiments on various stairways including indoor and outdoor are given in various light conditions. The results validate our algorithm.
