This study evaluates the effects of a fall
experience caused by tripping during the repetitive stepping movements over
an obstacle [obstacle-single leg forward step (OSFS) test]. The study included
147 participants who were divided into 2 groups: 25 fallers caused by tripping
and 122 nonfallers. The subjects were asked to step forward over a 10-cm-high
obstacle with 1 leg and then return to their original position, as quickly as
possible, and this test was repeated for 5 times. The OSFS test was evaluated
in 2 phases: the OSFS-F phase, wherein the participants stepped forward on
one leg, and the OSFS-R phase, wherein they returned to their original
position. Significant differences were observed in both phases of the OSFS
test between the two groups, and the fallers by tripping were significantly
inferior to the nonfallers. The area under the curve [AUC; area under the
receiver operating characteristic (ROC) curve] was more than 0.63 for all the
parameters, which was statistically significant. In conclusion, the fallers
by tripping were inferior to the nonfallers in the obstacle step movement.
