designing the self-balancing two-wheeled mobile robots and reducing undesired vibrations are of great importance. for this purpose, the majority of researches are focused on application of relatively complex control approaches without improving the robot structure. therefore, in this paper we introduce a new two-wheeled mobile robot which, despite its relative simple structure, fulfills the req...
This paper describes the mechanical devices, the movements and the associated kinematic models of a novel wheelchair prototype capable of climbing staircases. The key feature of the mechanical design is the use of two decoupled mechanisms in each axle, one used to negotiate steps, and the other to position the axle with respect to the chair to accommodate the overall slope. This decoupling make...
BACKGROUND Stair climbing is a challenging task to the elderly being the task with the first complaint in patients with mild to moderate knee osteoarthritis. Stair climbing results in around six times more compressive load transmitted through the knee joint than walking on level ground. The purpose of this study was to assess whether lateral wedge insoles would reduce medial compartment knee lo...
AIM As society ages, there is a vast number of elderly people with locomotive syndrome. In this study, the factors associated with functional limitations in daily living activities evaluated by female hip osteoarthritis (OA) patients were investigated. METHODS This study was a cross-sectional study. The subjects were 353 female patients who were newly diagnosed with hip OA at an orthopedic cl...
Background. Stair climbing is often performed by people in daily life and requires considerable energy muscle effort. This task has been widely described the literature, but role of knee joint ligaments not sufficiently investigated. could be relevant for planning ligament reconstruction surgery, providing suggestions to subjects with partial injuries, identifying compensatory strategies reduci...
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...
