Falls from Ladders
z More than 17% of occupational fatal falls are
from ladders (. Bureau of Labor Statistics, 2001).
z More falls occur from ladders in non-
occupational settings (Tsipouras et al 2001).

Falls from Ladders
z More than 17% of occupational fatal falls are
from ladders (. Bureau of Labor Statistics, 2001).
z More falls occur from ladders in non-
occupational settings (Tsipouras et al 2001).
z 20-27% ladder fall injuries need to be
hospitalized for 7-8 days (Björnstig and Johnsson
1992; Faergemann and Larsen 2000).
z Ladder falls cause serious injuries in older
adults (Björnstig & Johnsson 1992; Faergemann &
Larsen 2000,2001).
z Lateral falls are the most frequent cause of
injuries of stepladder accidents (Björnstig &
Johnsson 1992).

Research Questions
z What are the factors that affect lateral stability of a
human standing on a rigid, non-fixed, raised structure?
z How does the lateral pliance affect
subjects’ stepping and balancing behavior?
z Are there any age or gender effects on such behavior?
z Are there any learning effects on balancing on a
pliant raised structure?
z Can we improve the safety of such structures?
