The required coefficient of friction (RCOF), a parameter highly predictive of risk of slipping, was measured on thirty-one young male adults during level gait on three separate days before slipping, immediately (<10 minutes) after slipping, and either one, two, four, or six weeks later.  On average, the RCOF decreased 12% from its baseline value (0.20) after slipping, indicating the adoption of a protective gait with a decreased risk of slipping.  The RCOF data trended toward baseline values 4-6 weeks after the slip experience, but remained statistically different from baseline.  This indicates that the slip-induced gait alterations have long-lasting effects, enduring up to six weeks after the slip experience.  ETDIn CopyrightBiomechanicsSlips and fallsGait adaptationsRCOFThesis
