In this study, the influence of different external weight distribution on human gait and balance during obstacle negotiation maneuvers different age groups was investigated. Eight healthy participants performed different walking tasks on a force plate embedded walkway with different loading while their gait performance was evaluated. Results demonstrated that older adults showed significantly deteriorated gait performance and increased variability during the obstacle crossing phase. In addition, weight distribution also affected human gait performance significantly. Results of the current study provide useful data for new approaches to design improvements which will enhance human performance and prevent falling injuries.
