A Review of Lower Limb Exoskeleton Assistive Devices for Sit-To-Stand and Gait Motion

Abstract

This paper reviews several lower extremity wearable exoskeleton devices designed for people with various degrees of lower limb disabilities. Such devices provide an autonomous way to regain the ability to standup, sit down, and to walk. The goal of this work is to exhibit the different technologies used in devising exoskeletons up to date and to outline their features or their embedded techniques. Each exoskeleton system reviewed in this paper represents a technique that tackles issues associated with these devices such as comfort, ease of use, and compliance to its intended use. Eventually developers of exoskeletons offer users of such robotic systems a better life style.
