• Description:
  Slip, trip, and fall accidents result in 20-40% of disabling injuries in industry with as many as half of these coming from slipping alone (Courtney et al., 2001). The number of incidences and resulting injury severity increases with age (Courtney et al., 2001). Center of mass (COM) position and velocity with respect to the base of support (BOS) are important in recovery from a slip perturbation during sit to stand tasks (Pai and Patton, 1997) and walking (Bhatt et al., 2006). Bhatt and colleagues have used an inverted pendulum model of the body to show that the saggittal plane angle and angular velocity of the COM with respect to the BOS are important predictors of istability during slipping (Bhatt et al., 2006). Intuitively, angular acceleration of the COM with respect to the BOS at heel contact (HC) may also be important as it affects angle and angular velocity measures. Yet, this variable has not been investigated in previous research. Thus, the purpose of this study is to examine differences in COM angular acceleration at HC between slip-recovery and slip-fall outcomes in young and older adults. [Description provided by NIOSH]
