In an aging society it is extremely important to develop devices, which can support and aid the elderly in their daily life. This demands means and tools that extend independent living and promote improved health. Thus, the goal of this article is to review the state of the art in the robotic technology for mobility assistive devices for people with(More)
Cerebrovascular accidents (CVA) and spinal cord injuries (SCI) are the most common causes of paralysis and paresis with reported prevalence of 12,000 cases per million and 800 cases per million, respectively. Disabilities that follow CVA (hemiplegia) or SCI (paraplegia, tetraplegia) severely impair motor functions (e.g., standing, walking, reaching and(More)
This article presents a corrosion resistant, maneuverable, and intrinsically safe fiber Bragg grating (FBG)-based temperature optical sensor. Temperature monitoring is a critical activity for the oil and gas industry. It typically involves acquiring the desired parameters in a hazardous and corrosive environment. The use of polytetrafluoroethylene (PTFE)(More)
Walker devices are often prescribed incorrectly to patients, leading to the increase of dissatisfaction and occurrence of several problems, such as, discomfort and pain. Thus, it is necessary to objectively evaluate the effects that assisted gait can have on the gait patterns of walker users, comparatively to a non-assisted gait. A gait analysis, focusing(More)
Walkers are commonly seen in hospitals and clinics, but only individuals with fairly good motor function can use them. Hence, walkers should be more adaptive to the various needs of the users. This study includes the conceptual design, implementation and validation of a Smart Walker with a new interface approach integrated. The implementation of the(More)
Nowadays, walkers are prescribed based on subjective standards that lead to incorrect indication of such devices to patients. This leads to the increase of dissatisfaction and occurrence of discomfort and fall events. Therefore, it is necessary to objectively evaluate the effects that walker can have on the gait patterns of its users, comparatively to(More)
