• Description:
  Tripping accounts for an estimated 53% of falls among older adults. The most common measure for characterizing the probability of tripping is the minimum foot clearance (MFC) during swing. A decrease in the central tendency (i.e. mean/median) of MFC, or an increase in MFC variability, are both associated with an increased probability of tripping. These indirect measures of probability of tripping can lead to ambiguous results, though, when both increase or decrease simultaneously. Moreover, median MFC and MFC IQR are positively correlated, indicating concurrent increases or decreases in both are to be expected. The purpose of this study was to determine the probability of tripping using a method that avoids this ambiguous situation, and to demonstrate how this method can be used to compare this probability between groups of interest. This method was used to investigate differences in the probability of tripping between females and males, based upon reports of elevated risks of falling and sustaining a fall-related injury among females.
