Influence of body weight unloading on human gait characteristics : A systematic review

摘要: Body weight support (BWS) systems have shown promise as rehabilitation tools for neurologically impaired individuals. This paper reviews the experiment-based research on BWS with aim: (1) To investigate influence of body unloading (BWU) gait characteristics; (2) study whether effects differ between treadmill and overground walking (3) if modulated BWU influences characteristics less than unmodulated BWU. A systematic literature search was conducted in following engines: Pubmed, Scopus, Web Science Google Scholar. Statistical analysis used to quantify parameters. 54 studies experiments healthy individuals a system were included 32 these statistical analysis. Literature classified using three distinctions: or walking; type subjects nature force. Only 27% based subjects; low number considering that they are primary user group systems.
