Abstract
Slips, trips and falls are one of the leading causes of injury and result in billions of dollars in medical and insurance costs annually. Current determination of slip potential does not always accurately predict whether an individual will slip or not. To better predict slip incidents, it may be possible to evaluate only one component, horizontal force, of the current friction calculation. The purpose of this dissertation was to determine if horizontal force generation would serve as a more accurate predictor of slip probability for movements associated with a high-risk of slipping; a 90° change in direction. It was discovered that if at least 50N of horizontal force was generated by 10.08ms following heel-strike, the corresponding slip distance was less than 100mm. By using the horizontal force generation associated with early heel-strike, the probability of correctly classifying slip and non-slip situations was greater compared to the currently utilized friction method.
