Trends in Robotic Systems for Lower Limb Rehabilitation

The aim of this review is to analyze robotic systems used in lower limb rehabilitation, focusing on signal acquisition, processing, and intelligent system applications. Literature research was done using keywords giving an initial result of 130 publications, to which inclusion and exclusion criteria were applied, giving 58 related publications found during the last ten years. The increasing development of intelligent systems applied to assistive or rehabilitation devices allows one to find new ways of robotic systems usage, in the coming future, in this area. The use of bibliometric analysis software shows the areas of greatest relevance in the conception of this type of system. Finally, from the state-of-the-art research conducted allows to show in this document the most relevant assistive or rehabilitation robotic systems, their main characteristics, their functionality, as well as future trends.
