摘要: It is likely that many stair accidents result from a trip during negotiation, yet few studies have examined the exact nature of balance loss falls on stairs. The purpose this study was to investigate potential age-related differences in minimum clearance foot descent, and explore whether affected by available ambient lighting. Twelve young adults (24+/-3.3 years) 10 older (73.7+/-1.9 participated study. had significantly greater within subject coefficients variation compared adults, larger number clearances which fell below 5 mm. While subjects increased their 3.6 mm average response decrease lighting, maintained same over all stairs except one. These results suggest variability clearance, lack precautionary increases under reduced lighting may contribute elderly.
