Abstract
Fall is one of the leading causes of fatal and nonfatal injuries in older adults. Fall may lead to different kinds of harms such as physical and cognitive problems, psychological impairments or even death. More than 30% of older adults aged 65 and above experience fall every year. As people age, their ability in maintaining balance reduces, causing an increase in the incidence of fall. There are many prevention strategies and interventions presented to minimize the incidence of fall over the last decades in terms of exercising, improving fall-related knowledge, modifying home facilities, and assistive devices. This chapter presents a review of mobility-assistive devices including canes, wheelchairs, exoskeletons, and walkers for mobility-impaired people. In particular, the chapter also focuses on smart walking devices and highlights their features and subsystems with the aim to investigate their limitations.
