Stepping through fear
Description
A database from research on fear of falling in 81 older women over the age of 60. Based on the Short FES-I survey, the participants were divided into three groups with low, medium, and high levels of fear. Step initiation was assessed using two force platforms. The transitional task was executed under four different conditions: unper- turbed crossing, crossing obstacle, and step-up and step- down. The evaluated variables were: TT (s) – transit time, the duration of the transit phase; – S1 (s) – stability time 1 (preparatory stability time), time from the start of the 2nd phase to the first foot contact with the second platform (Fzplat2 > 0); – S2 (s) – stability time 2 (regained stability time), time from lifting the foot off the first platform (Fzplat2 = 0) to the start of the 3rd phase; – DST (s) – double-support time, when each foot is in contact with one of the platforms.
