Abstract
Falls are a leading cause of fatal and nonfatal injuries in adults, and slipping while walking accounts for 40% of these incidents. While slip research has focused on straight, level walking, 35-45% of daily steps turn our bodies in a new direction. No studies have characterized slips that occur during turns, which is crucial to developing fall prevention measures. Therefore, we hypothesized that slip attributes of the sliding foot (i.e. direction, distance, and peak velocity) will be influenced by slip context (i.e. slipped foot, slip onset phase, and turn radius). 18 young adults participated in a prospective, repeated measures study where they encountered slips delivered by the Wearable Apparatus for Slip Perturbations on 180° curvilinear turns. Subjects performed 12 trials to experience every combination of turn radius, onset phase, and slipped foot. Slip attributes were derived from kinematic data collected via motion capture system, and linear mixed effects models were built for each. Slip context had the greatest effect on slip directions, with main effects of and an interaction between slipped foot and onset phase (all p
