Abstract Summary
The purpose of this study was to investigate bilateral lower extremity (hip, knee, ankle) and distal lead foot kinematics during transition step negotiation in young women (YA) and older women with (OFH) and without (ONF) a fall history. Participants in the YA (n=6), OFH (n=4), and ONF (n=3) groups completed 5 trials in which they walked barefoot along a raised walkway for 3 m, descended a 17.3 cm step and continued walking 3 m. There were no significant differences in minimum step clearance between the groups. Further, neither the lower extremity positions at step clearance nor the distal foot kinematics during weight acceptance differed between the groups.
