• Description:
  Injuries and fatalities related to slips, trips, and falls continue to be prevalent in several occupational environments. A number of previous studies have found that localized muscle fatigue (LMF) can lead to gait changes that can increase the risk of slips and falls. For example, knee extensor fatigue increased the required coefficient of friction (RCOF) and heel contact velocity (HCV), both indicators of higher slip risk. Among the lower extremity muscles, the ankle musculature plays an important role in human locomotion and maintaining standing balance. Yet, changes in biomechanical gait parameters associated with ankle muscle fatigue, and its relationship to slip- and trip-induced fall accidents, have not been reported previously to our knowledge. Therefore, the primary objective of the current study was to investigate the effects of ankle fatigue on gait characteristics. It was hypothesized that LMF of the ankle would affect both kinematic and kinetic variables in a way that potentially leads to higher risks of slip- and trip-induced falls.
