• Description:
  The friction between the shoe and floor, as measured by the coefficient of friction (COF), is predictive of slip and fall accidents. Developing COF tests requires a comprehensive understanding of the under-shoe mechanics during gait. This study assessed the effects of gender, age, weight, and height on the dynamics of slipping. The gait patterns of 22 older adults (14 female) and 11 younger adults (7 female) were recorded as they experienced an unexpected slip. Under-shoe mechanics (force, shoe angle, and sliding speed) were recorded at the moment when the foot began to slip. Increased height was correlated with increased normal force (p=0.0121) and shoe angle (p=0.0054) but not with sliding speed. Gender, age group, and weight did not significantly affect any of these variables. The COF of the shoe is known to be sensitive to normal force and shoe angle, indicating that individuals of different heights may experience different slip risk. View full paper here.
